(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ).

See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations.

It’s been available across browsers since ⁨July 2015⁩. * Some parts of this feature may have varying levels of support. Learn more See full compatibility Report feedback The <link> HTML element specifies relationships between the current document and an external resource. This element is most commonly used to link to stylesheets , but is also used to establish site icons (both "favicon" style icons and icons for the home screen and apps on mobile devices) among other things. In this article Try it Attributes Examples Technical summary Specifications Browser compatibility See also Try it <link href="/shared-assets/misc/link-element-example.css" rel="stylesheet" /> <p>This text will be red as defined in the external stylesheet.</p> <p style="color: blue"> The <code>style</code> attribute can override it, though. </p> To link an external stylesheet, you'd include a <link> element inside your <head> like this: html <link href="main.css" rel="stylesheet" /> This example provides the path to the stylesheet inside an href attribute and a rel attribute with a value of stylesheet . The rel stands for "relationship", and is one of the key features of the <link> element — the value denotes how the item being linked to is related to the containing document. There are a number of other common types you'll come across. For example, a link to the site's favicon: html <link rel="icon" href="favicon.ico" /> There are a number of other icon rel values, mainly used to indicate special icon types for use on various mobile platforms, e.g.: html <link rel="apple-touch-icon" sizes="114x114" href="apple-icon-114.png" type="image/png" /> The sizes attribute indicates the icon size, while the type contains the MIME type of the resource being linked. These provide useful hints to allow the browser to choose the most appropriate icon available. You can also provide a media type or query inside a media attribute; this resource will then only be loaded if the media condition is true. For example: html <link href="print.css" rel="stylesheet" media="print" /> <link href="mobile.css" rel="stylesheet" media="screen and (width <= 600px)" /> Some interesting new performance and security features have been added to the <link> element too. Take this example: html <link rel="preload" href="myFont.woff2" as="font" type="font/woff2" crossorigin="anonymous" /> A rel value of preload indicates that the browser should preload this resource (see rel="preload" for more details), with the as attribute indicating the specific class of content being fetched. The crossorigin attribute indicates whether the resource should be fetched with a CORS request. Other usage notes: A <link> element can occur either in the <head> or <body> element, depending on whether it has a link type that is body-ok . For example, the stylesheet link type is body-ok, and therefore <link rel="stylesheet"> is permitted in the body. However, this isn't a good practice to follow; it makes more sense to separate your <link> elements from your body content, putting them in the <head> . When using <link> to establish a favicon for a site, and your site uses a Content Security Policy (CSP) to enhance its security, the policy applies to the favicon. If you encounter problems with the favicon not loading, verify that the Content-Security-Policy header's img-src directive is not preventing access to it. The HTML and XHTML specifications define event handlers for the <link> element, but it is unclear how they would be used. Under XHTML 1.0, void elements such as <link> require a trailing slash: <link /> . WebTV supports the use of the value next for rel to preload the next page in a document series. Attributes This element includes the global attributes . as This attribute is required when rel="preload" has been set on the <link> element, optional when rel="modulepreload" has been set, and otherwise should not be used. It specifies the type of content being loaded by the <link> , which is necessary for request matching, application of correct content security policy , and setting of correct Accept request header. Furthermore, rel="preload" uses this as a signal for request prioritization. The table below lists the valid values for this attribute and the elements or resources they apply to. Value Applies To audio <audio> elements document <iframe> and <frame> elements embed <embed> elements fetch fetch, XHR Note: This value also requires <link> to contain the crossorigin attribute, see CORS-enabled fetches . font CSS @font-face Note: This value also requires <link> to contain the crossorigin attribute, see CORS-enabled fetches . image <img> and <picture> elements with srcset or imageset attributes, SVG <image> elements, CSS *-image rules object <object> elements script <script> elements, Worker importScripts style <link rel=stylesheet> elements, CSS @import track <track> elements video <video> elements worker Worker, SharedWorker blocking This attribute explicitly indicates that certain operations should be blocked until specific conditions are met. It must only be used when the rel attribute contains the expect or stylesheet keywords. With rel="expect" , it indicates that operations should be blocked until a specific DOM node has been parsed. With rel="stylesheet" , it indicates that operations should be blocked until an external stylesheet and its critical subresources have been fetched and applied to the document. The operations that are to be blocked must be a space-separated list of blocking tokens listed below. Currently there is only one token: render : The rendering of content on the screen is blocked. Note: Only link elements in the document's <head> can possibly block rendering. By default, a link element with rel="stylesheet" in the <head> blocks rendering when the browser discovers it during parsing. If such a link element is added dynamically via script, you must additionally set blocking = "render" for it to block rendering. crossorigin This enumerated attribute indicates whether CORS must be used when fetching the resource. CORS-enabled images can be reused in the <canvas> element without being tainted . The allowed values are: anonymous A cross-origin request (i.e., with an Origin HTTP header) is performed, but no credential is sent (i.e., no cookie, X.509 certificate, or HTTP Basic authentication). If the server does not give credentials to the origin site (by not setting the Access-Control-Allow-Origin HTTP header) the resource will be tainted and its usage restricted. use-credentials A cross-origin request (i.e., with an Origin HTTP header) is performed along with a credential sent (i.e., a cookie, certificate, and/or HTTP Basic authentication is performed). If the server does not give credentials to the origin site (through Access-Control-Allow-Credentials HTTP header), the resource will be tainted and its usage restricted. If the attribute is not present, the resource is fetched without a CORS request (i.e., without sending the Origin HTTP header), preventing its non-tainted usage. If invalid, it is handled as if the enumerated keyword anonymous was used. See CORS settings attributes for additional information. disabled For rel="stylesheet" only, the disabled Boolean attribute indicates whether the described stylesheet should be loaded and applied to the document. If disabled is specified in the HTML when it is loaded, the stylesheet will not be loaded during page load. Instead, the stylesheet will be loaded on-demand, if and when the disabled attribute is changed to false or removed. Setting the disabled property in the DOM causes the stylesheet to be removed from the document's Document.styleSheets list. fetchpriority Provides a hint of the relative priority to use when fetching a resource of a particular type. Allowed values: high Fetch the resource at a high priority relative to other resources of the same type. low Fetch the resource at a low priority relative to other resources of the same type. auto Don't set a preference for the fetch priority. This is the default. It is used if no value or an invalid value is set. href This attribute specifies the URL of the linked resource. A URL can be absolute or relative. hreflang This attribute indicates the language of the linked resource. It is purely advisory. Values should be valid BCP 47 language tags . Use this attribute only if the href attribute is present. imagesizes For rel="preload" and as="image" only, the imagesizes attribute has similar syntax and semantics as the sizes attribute that indicates to preload the appropriate resource used by an img element with corresponding values for its srcset and sizes attributes. imagesrcset For rel="preload" and as="image" only, the imagesrcset attribute has similar syntax and semantics as the srcset attribute that indicates to preload the appropriate resource used by an img element with corresponding values for its srcset and sizes attributes. integrity Contains inline metadata — a base64-encoded cryptographic hash of the resource (file) you're telling the browser to fetch. The browser can use this to verify that the fetched resource has been delivered without unexpected manipulation. The attribute must only be specified when the rel attribute is specified to stylesheet , preload , or modulepreload . See Subresource Integrity . media This attribute specifies the media that the linked resource applies to. Its value must be a media type / media query . This attribute is mainly useful when linking to external stylesheets — it allows the user agent to pick the best adapted one for the device it runs on. referrerpolicy A string indicating which referrer to use when fetching the resource: no-referrer means that the Referer header will not be sent. no-referrer-when-downgrade means that no Referer header will be sent when navigating to an origin without TLS (HTTPS). This is a user agent's default behavior, if no policy is otherwise specified. origin means that the referrer will be the origin of the page, which is roughly the scheme, the host, and the port. origin-when-cross-origin means that navigating to other origins will be limited to the scheme, the host, and the port, while navigating on the same origin will include the referrer's path. unsafe-url means that the referrer will include the origin and the path (but not the fragment, password, or username). This case is unsafe because it can leak origins and paths from TLS-protected resources to insecure origins. rel This attribute names a relationship of the linked document to the current document. The attribute must be a space-separated list of link type values . sizes This attribute defines the sizes of the icons for visual media contained in the resource. It must be present only if the rel contains a value of icon or a non-standard type such as Apple's apple-touch-icon . It may have the following values: any , meaning that the icon can be scaled to any size as it is in a vector format, like image/svg+xml . a white-space separated list of sizes, each in the format <width in pixels>x<height in pixels> or <width in pixels>X<height in pixels> . Each of these sizes must be contained in the resource. Note: Most icon formats are only able to store one single icon; therefore, most of the time, the sizes attribute contains only one entry. Microsoft's ICO format and Apple's ICNS format can store multiple icon sizes in a single file. ICO has better browser support, so you should use this format if cross-browser support is a concern. title The title attribute has special semantics on the <link> element. When used on a <link rel="stylesheet"> it defines a default or an alternate stylesheet . type This attribute is used to define the type of the content linked to. The value of the attribute should be a MIME type such as text/html , text/css , and so on. The common use of this attribute is to define the type of stylesheet being referenced (such as text/css ), but given that CSS is the only stylesheet language used on the web, not only is it possible to omit the type attribute, but is actually now recommended practice. It is also used on rel="preload" link types, to make sure the browser only downloads file types that it supports. Non-standard attributes target Deprecated Defines the frame or window name that has the defined linking relationship or that will show the rendering of any linked resource. Obsolete attributes charset Deprecated This attribute defines the character encoding of the linked resource. The value is a space- and/or comma-delimited list of character sets as defined in RFC 2045 . The default value is iso-8859-1 . Note: To produce the same effect as this obsolete attribute, use the Content-Type HTTP header on the linked resource. rev Deprecated The value of this attribute shows the relationship of the current document to the linked document, as defined by the href attribute. The attribute thus defines the reverse relationship compared to the value of the rel attribute. Link type values for the attribute are similar to the possible values for rel . Note: Instead of rev , you should use the rel attribute with the opposite link type value . For example, to establish the reverse link for made , specify author . Also, this attribute doesn't stand for "revision" and must not be used with a version number, even though many sites misuse it in this way. Examples Including a stylesheet To include a stylesheet in a page, use the following syntax: html <link href="style.css" rel="stylesheet" /> Providing alternative stylesheets You can also specify alternative style sheets . The user can choose which style sheet to use by choosing it from the View > Page Style menu. This provides a way for users to see multiple versions of a page. html <link href="default.css" rel="stylesheet" title="Default Style" /> <link href="fancy.css" rel="alternate stylesheet" title="Fancy" /> <link href="basic.css" rel="alternate stylesheet" title="Basic" /> Providing icons for different usage contexts You can include links to several icons on the same page, and the browser will choose which one works best for its particular context using the rel and sizes values as hints. html <!-- iPad Pro with high-resolution Retina display: --> <link rel="apple-touch-icon" sizes="167x167" href="/apple-touch-icon-167x167.png" /> <!-- 3x resolution iPhone: --> <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon-180x180.png" /> <!-- non-Retina iPad, iPad mini, etc.: --> <link rel="apple-touch-icon" sizes="152x152" href="/apple-touch-icon-152x152.png" /> <!-- 2x resolution iPhone and other devices: --> <link rel="apple-touch-icon" href="/apple-touch-icon-120x120.png" /> <!-- basic favicon --> <link rel="icon" href="/favicon.ico" /> For information about what sizes to choose for Apple icons, see Apple's documentation on configuring web applications and the referenced Apple human interface guidelines . Usually, it is sufficient to provide a large image, such as 192x192, and let the browser scale it down as needed, but you may want to provide images with different levels of detail for different sizes, as the Apple design guideline recommends. Providing smaller icons for lower resolutions also saves bandwidth. It may not be necessary to provide <link> elements at all. For example, browsers automatically request /favicon.ico from the root of a site, and Apple also automatically requests /apple-touch-icon-[size].png , /apple-touch-icon.png , etc. However, providing explicit links protects you against changes to these conventions. Conditionally loading resources with media queries You can provide a media type or query inside a media attribute; this resource will then only be loaded if the media condition is true. For example: html <link href="print.css" rel="stylesheet" media="print" /> <link href="mobile.css" rel="stylesheet" media="all" /> <link href="desktop.css" rel="stylesheet" media="screen and (width >= 600px)" /> <link href="highres.css" rel="stylesheet" media="screen and (resolution >= 300dpi)" /> Stylesheet load events You can determine when a style sheet has been loaded by watching for a load event to fire on it; similarly, you can detect if an error has occurred while processing a style sheet by watching for an error event: html <link rel="stylesheet" href="mystylesheet.css" id="my-stylesheet" /> js const stylesheet = document.getElementById("my-stylesheet"); stylesheet.onload = () => { // Do something interesting; the sheet has been loaded }; stylesheet.onerror = () => { console.log("An error occurred loading the stylesheet!"); }; Note: The load event fires once the stylesheet and all of its imported content has been loaded and parsed, and immediately before the styles start being applied to the content. Preload examples You can find a number of <link rel="preload"> examples in Preloading content with rel="preload" . Blocking rendering till a resource is fetched You can include render token inside a blocking attribute; the rendering of the page will be blocked till the resource and its critical subresources are fetched and applied to the document. For example: html <link blocking="render" rel="stylesheet" href="example.css" crossorigin /> Technical summary Content categories Metadata content. If itemprop is present: Flow content and phrasing content . Permitted content None; it is a void element . Tag omission Must have a start tag and must not have an end tag.

Report Abuse YouTube Golf Posted on Jul 10, 2025 Golf.com: Warming Up with Jon Rahm and Tyrrell Hatton # golfyoutube # livgolf # rydercup # mentalgame Jon Rahm and Tyrrell Hatton team up on GOLF.com’s Warming Up series, showing why they’re golf soulmates both on and off the course. They share plenty of laughs—Hatton calls Rahm a “big teddy bear” despite his fierce on-course look, while Rahm insists Hatton is “one of the funniest people you’ll ever meet.” Beyond the jokes, they dive into their game-day mindsets: Rahm says he’s “irrationally positive,” whereas Hatton warns that too much positivity can drain you. Their chemistry and contrasting approaches make this rare two-player interview a must-watch for golf fans.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality.

Navigation Node.js SDK Trigger Workflow from API Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog Node.js SDK Trigger Workflow from API OpenAI Open in ChatGPT Learn how to trigger workflows using direct workflow API, with code snippets and examples. OpenAI Open in ChatGPT It is a unified API to trigger workflow and doesn’t require user creation before hand to trigger notification. Recommended for platforms transitioning their existing notifications to SuprSend. If you are using our frontend SDKs to configure notifications and passing events and user properties from third-party data platforms like Segment, then event-based trigger would be a better choice. 📘 Available in SDK version >= 1.10.0 ​ Payload Schema Once your request is accepted, you can check the status of your request in the SuprSend Logs . Sample Payload Response Copy Ask AI const { Suprsend , WorkflowTriggerRequest } = require ( "@suprsend/node-sdk" ); const supr_client = new Suprsend ( "_workspace_key_" , "_workspace_secret_" ); // Prepare workflow payload const body = { "workflow" : "_workflow_slug_" , "actor" : { "distinct_id" : "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08" , "name" : "actor_1" , "$skip_create" : true }, "recipients" : [ // notify user { "distinct_id" : "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09" , "$email" : [ " [email protected] " ], "name" : "recipient_1" , "$preferred_language" : "en" , "$timezone" : "America/New_York" , "$skip_create" : true }, // notify object { "object_type" : "teams" , "id" : "finance" , "$skip_create" : true } ], "data" : { "first_name" : "User" , "invoice_amount" : "$5000" , "invoice_id" : "Invoice-1234" } }; // Create workflow instance const w1 = new WorkflowTriggerRequest ( body , { tenant_id: "tenant_id1" , idempotency_key: "_unique_identifier_of_the_request_" }); // Trigger workflow const response = supr_client . workflows . trigger ( w1 ); response . then ( res => console . log ( "response" , res )); To prevent automatic creation of an actor, or recipient (user/object) in SuprSend (the case where they already exist in your system), you can use the "$skip_create": true flag. This can be applied inside the actor, individual user recipient objects, or object recipient objects. Property Type Description workflow string Slug of the designed workflow on the SuprSend dashboard. You’ll get the slug from workflow settings. recipients array of string / array of objects List of users who need to be notified. You can add up to 100 recipients in a workflow trigger. You can either pass recipients as an array of distinct_ID (if the user is pre-synced in the SuprSend database) or define recipient information inline . actor (Optional) string / object Includes distinct_id and properties of the user who performed the action. You can use it for cross-user notifications where you need to include actor properties in the notification template. Actor properties can be added as $actor.<prop> . data object Variable data required to render dynamic template content or workflow properties such as dynamic delay or channel override in the send node. tenant_id (Optional) string Trigger workflow for a specific tenant/brand. idempotency_key (Optional) string Unique identifier of the request. We’ll be returning idempotency_key in our outbound webhook response . You can use it to map notification statuses and replies in your system. recipients[].$preferred_language string To set the recipient’s preferred language. This is to support localization in notification content. You can pass the language in ISO 639-1 2-letter format. Refer to all language codes here . recipients[].$timezone string To set the recipient’s timezone. Used to send notifications in the user’s local timezone. You can pass the timezone in IANA (TZ identifier) format. ​ Sending notification to Multiple Users Recipients in workflow call is an array of distinct_ids or recipient objects. You can pass up to 100 recipients in a single workflow trigger. SuprSend will internally convert it into multiple workflow triggers, one for each recipient in the array. json Copy Ask AI "recipients" : [ "distinct_id1" , "distinct_id2" ] ---- OR ------ "recipients" : [ { "distinct_id" : "id1" , "$email" :[ " [email protected] " ], "name" : "recipient_1" }, { "distinct_id" : "id1" , "$email" :[ " [email protected] " ], "name" : "recipient_2" } ] Use lists to broadcast to a large list of users: We recommend you to use lists and broadcast to send notifications to a user list larger than 1000 users. This approach allows bulk processing, resulting in significantly faster delivery compared to individual workflow calls. Sending individual workflows to a large set of users may introduce delays in your notification queue. ​ Identifying Recipients Inline One of the benefits of using direct workflow trigger is that you can identify recipients inline. You can include recipient channel information, their channel preferences, and their user properties along with the workflow trigger. Upon triggering the workflow, the recipient will be automatically created in the SuprSend database in the background. This facilitates dynamic synchronization of your user data within SuprSend and eliminates the need for any migration efforts on your end to start sending notifications from SuprSend. You can also use recipient properties in your template as $recipient.<property> . This is how the complete recipient object with look like json Copy Ask AI "recipients" : [{ "distinct_id" : "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09" , "$email" :[ " [email protected] " ], // email communication channel "$sms" :[ "+15555555555" ], // sms communication channel "$channels" :[ "email" , "inbox" ], "$preferred_language" : "en" , "$timezone" : "America/New_York" , "custom_prop1" : "value_1" , // custom property "custom_prop2" : "value_2" , // custom property }] Property Type Description distinct_id string Unique identifier of the user to be notified. communication channels ( $email , $sms , etc.) array of string / objects The communication channel info provided will be updated in the user profile in the background. For this workflow, only the specified channel values for this recipient will be used for sending notifications instead of all channel values present in the user profile. $channels array of string By default, notifications will be sent to all channels defined in the workflow delivery nodes. However, if a user has a specific channel preference for a notification (e.g. they only want to receive payment reminders via email), you can include that preference in the workflow payload. This ensures notifications are sent only to the channels specified here. Supported channels: email, sms, whatsapp, androidpush, iospush, slack, webpush, ms_teams .You can always use our in-built preference APIs to maintain user notification preferences. Preferences defined within SuprSend will automatically apply with workflow triggers. $preferred_language string Sets the recipient’s preferred language to support localization in notification content. You can pass the language in ISO 639-1 2-letter format. Refer to all language codes here . $timezone string Sets the recipient’s timezone to send notifications in the user’s local timezone. You can pass the timezone in IANA (TZ identifier) format. * object You can pass other user properties to render dynamic template content. These properties will also be set in the user profile and can be used in the template as $recipient.<property> . ​ Add user communication channel json Copy Ask AI "$email" :[ " [email protected] " ], "$whatsapp" :[ "+15555555555" ], "$sms" :[ "+15555555555" ], "$androidpush" : [{ "token" : "__android_push_token__" , "provider" : "fcm" , "device_id" : "" }], "$iospush" :[{ "token" : "__ios_push_token__" , "provider" : "apns" , "device_id" : "" }], // slack using email "$slack" : [{ "email" : " [email protected] " , "access_token" : "xoxb-XXXXXXXX" }] // slack using member_id "$slack" : [{ "user_id" : "U/WXXXXXXXX" , "access_token" : "xoxb-XXXXXX" }] // slack channel "$slack" : [{ "channel" : "CXXXXXXXX" , "access_token" : "xoxb-XXXXXX" }] // slack incoming webhook "$slack" : [{ "incoming_webhook" : { "url" : "https://hooks.slack.com/services/TXXXX/BXXXX/XXXXXXX" } }] // MS teams user or channel using conversation_id "$ms_teams" : [{ "tenant_id" : "c1981ab2-9aaf-xxxx-xxxx" , "service_url" : "https://smba.trafficmanager.net/amer" , "conversation_id" : "19:c1524d7c-a06f-456f-8abe-xxxx" }] // MS teams user using user_id "$ms_teams" : [{ "tenant_id" : "c1981ab2-9aaf-xxxx-xxxx" , "service_url" : "https://smba.trafficmanager.net/amer" , "user_id" : "29:1nsLcmJ2RKtYH6Cxxxx-xxxx" }] // MS teams incoming webhook "$ms_teams" : [{ "incoming_webhook" : { "url" : "https://wnk1z.webhook.office.com/webhookb2/XXXXXXXXX" } }] ​ Sending cross-user notifications In scenarios where you need to notify a group of users based on another user’s action, such as sending a notification to the document owner when someone comments on it, you can specify the actor in your workflow call. This allows you to use actor’s name or other properties in your notification template. Actor properties can be included in the template as $actor.<property> . text Copy Ask AI //handlebar template Hi { {$recipient.name }}, { {$actor.name }} added { {length comments }} new comments on the { {doc_name }}. // rendered content with Sample Data Hi recipient_ 1 , actor_ 1 added 2 new comments on the annual IT report. Sample Workflow Body Copy Ask AI { "workflow" : "new_comment" , "actor" : { "distinct_id" : "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08" , "name" : "actor_1" }, "recipients" : [ { "distinct_id" : "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09" , "$email" : [ " [email protected] " ], "name" : "recipient_1" } ], "data" :{ "doc_name" : "annual IT report" , "date" : "2024-01-01" , "comments" : [ "change the date" , "rest looks good" ] } } ​ Sending notification to anonymous user You can send notifications to anonymous users by passing "is_transient": true in your recipient object. This approach is recommended for scenarios where you need to send notifications to unregistered users without creating them in the SuprSend platform. The same way, you can pass "is_transient": true in your actor object to use actor properties in template without creating user profile. Request Copy Ask AI const workflow_payload = { "workflow" : "_workflow_slug_" , "actor" : { "is_transient" : true , // for anonymous actor "name" : "actor_1" }, "recipients" : [ { "is_transient" : true , // for anonymous recipient "$email" : [ " [email protected] " ], "name" : "recipient_1" } ], "data" : { "first_name" : "User" , "invoice_amount" : "$5000" , "invoice_id" : "Invoice-1234" } } ​ Multi-tenant notifications For cases where you want to send notifications to your enterprise customers end users, pass the tenant_id in your workflow instance. You can use this to dynamically manage tenant level notification customizations . This includes the ability to customize template design or content and route notifications via tenant vendors. Request Copy Ask AI const workflow = new WorkflowTriggerRequest ( workflow_body , { tenant_id: "tenant_id1" }) ​ Idempotent requests SuprSend supports idempotency to ensure that requests can be retried safely without duplicate processing. If Suprsend receives and processes a request with an idempotency_key, it will skip processing requests with same idempotency_key for next 24 hours. Idempotency key should be uniquely generated for each request (max 255 characters allowed). Spaces in start and end of the key will be trimmed. Here are some common approaches for generating idempotency keys: Generate a random UUID for each request. Construct the idempotency key by combining relevant information about the request . This can include parameters, identifiers, or specific contextual details that are meaningful within your application. e.g., you could concatenate the user ID, action, and timestamp to form an idempotency key like user147-new-comment-1687437670 Request-specific Identifier : If your request already contains a unique identifier, such as an order ID or a job ID, you can use that identifier directly as the idempotency key. javascript Copy Ask AI const workflow = new WorkflowTriggerRequest ( workflow_body , { idempotency_key: "_unique_request_identifier" }) ​ Bulk API for triggering multiple workflows Bulk API allows you to send multiple workflow requests in a single call. Use .append() and workflows.bulk_trigger_instance() to add however-many-records to call in bulk. Request Response Copy Ask AI const { Suprsend , WorkflowTriggerRequest } = require ( "@suprsend/node-sdk" ); const supr_client = new Suprsend ( "_workspace_key_" , "_workspace_secret_" ); // workflow1 instance const wf1 = new WorkflowTriggerRequest ( wf_body1 , { tenant_id: "tenant_id1" , idempotency_key: "_unique_identifier_of_the_request_" }) // workflow2 instance const wf2 = new WorkflowTriggerRequest ( body2 ) // create bulk instance const bulk_ins = supr_client . workflows . bulk_trigger_instance () // add workflows instances to bulk instance bulk_ins . append ( wf1 , wf2 ) // trigger workflows const response = bulk_ins . trigger (); response . then ( res => console . log ( "response" , res )); ​ Add attachment (in email) To add one or more attachments to a notification (viz. Email), call wf_instance.add_attachment() for each file with local path or remote attachment url. Ensure that file path is valid, and public(for remote url) otherwise it will raise error.

The principal built-in types are numerics, sequences, mappings, classes, instances and exceptions. Some collection classes are mutable. The methods that add, subtract, or rearrange their members in place, and don’t return a specific item, never return the collection instance itself but None . Some operations are supported by several object types; in particular, practically all objects can be compared for equality, tested for truth value, and converted to a string (with the repr() function or the slightly different str() function). The latter function is implicitly used when an object is written by the print() function. Truth Value Testing ¶ Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object. [ 1 ] If one of the methods raises an exception when called, the exception is propagated and the object does not have a truth value (for example, NotImplemented ). Here are most of the built-in objects considered false: constants defined to be false: None and False zero of any numeric type: 0 , 0.0 , 0j , Decimal(0) , Fraction(0, 1) empty sequences and collections: '' , () , [] , {} , set() , range(0) Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.) Boolean Operations — and , or , not ¶ These are the Boolean operations, ordered by ascending priority: Operation Result Notes x or y if x is true, then x , else y (1) x and y if x is false, then x , else y (2) not x if x is false, then True , else False (3) Notes: This is a short-circuit operator, so it only evaluates the second argument if the first one is false. This is a short-circuit operator, so it only evaluates the second argument if the first one is true. not has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b) , and a == not b is a syntax error. Comparisons ¶ There are eight comparison operations in Python. They all have the same priority (which is higher than that of the Boolean operations). Comparisons can be chained arbitrarily; for example, x < y <= z is equivalent to x < y and y <= z , except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false). This table summarizes the comparison operations: Operation Meaning < strictly less than <= less than or equal > strictly greater than >= greater than or equal == equal != not equal is object identity is not negated object identity Unless stated otherwise, objects of different types never compare equal. The == operator is always defined but for some object types (for example, class objects) is equivalent to is . The < , <= , > and >= operators are only defined where they make sense; for example, they raise a TypeError exception when one of the arguments is a complex number. Non-identical instances of a class normally compare as non-equal unless the class defines the __eq__() method. Instances of a class cannot be ordered with respect to other instances of the same class, or other types of object, unless the class defines enough of the methods __lt__() , __le__() , __gt__() , and __ge__() (in general, __lt__() and __eq__() are sufficient, if you want the conventional meanings of the comparison operators). The behavior of the is and is not operators cannot be customized; also they can be applied to any two objects and never raise an exception. Two more operations with the same syntactic priority, in and not in , are supported by types that are iterable or implement the __contains__() method. Numeric Types — int , float , complex ¶ There are three distinct numeric types: integers , floating-point numbers , and complex numbers . In addition, Booleans are a subtype of integers. Integers have unlimited precision. Floating-point numbers are usually implemented using double in C; information about the precision and internal representation of floating-point numbers for the machine on which your program is running is available in sys.float_info . Complex numbers have a real and imaginary part, which are each a floating-point number. To extract these parts from a complex number z , use z.real and z.imag . (The standard library includes the additional numeric types fractions.Fraction , for rationals, and decimal.Decimal , for floating-point numbers with user-definable precision.) Numbers are created by numeric literals or as the result of built-in functions and operators. Unadorned integer literals (including hex, octal and binary numbers) yield integers. Numeric literals containing a decimal point or an exponent sign yield floating-point numbers. Appending 'j' or 'J' to a numeric literal yields an imaginary number (a complex number with a zero real part) which you can add to an integer or float to get a complex number with real and imaginary parts. The constructors int() , float() , and complex() can be used to produce numbers of a specific type. Python fully supports mixed arithmetic: when a binary arithmetic operator has operands of different numeric types, the operand with the “narrower” type is widened to that of the other, where integer is narrower than floating point. Arithmetic with complex and real operands is defined by the usual mathematical formula, for example: x + complex ( u , v ) = complex ( x + u , v ) x * complex ( u , v ) = complex ( x * u , x * v ) A comparison between numbers of different types behaves as though the exact values of those numbers were being compared. [ 2 ] All numeric types (except complex) support the following operations (for priorities of the operations, see Operator precedence ): Operation Result Notes Full documentation x + y sum of x and y x - y difference of x and y x * y product of x and y x / y quotient of x and y x // y floored quotient of x and y (1)(2) x % y remainder of x / y (2) -x x negated +x x unchanged abs(x) absolute value or magnitude of x abs() int(x) x converted to integer (3)(6) int() float(x) x converted to floating point (4)(6) float() complex(re, im) a complex number with real part re , imaginary part im . im defaults to zero. (6) complex() c.conjugate() conjugate of the complex number c divmod(x, y) the pair (x // y, x % y) (2) divmod() pow(x, y) x to the power y (5) pow() x ** y x to the power y (5) Notes: Also referred to as integer division. For operands of type int , the result has type int . For operands of type float , the result has type float . In general, the result is a whole integer, though the result’s type is not necessarily int . The result is always rounded towards minus infinity: 1//2 is 0 , (-1)//2 is -1 , 1//(-2) is -1 , and (-1)//(-2) is 0 . Not for complex numbers. Instead convert to floats using abs() if appropriate. Conversion from float to int truncates, discarding the fractional part. See functions math.floor() and math.ceil() for alternative conversions. float also accepts the strings “nan” and “inf” with an optional prefix “+” or “-” for Not a Number (NaN) and positive or negative infinity. Python defines pow(0, 0) and 0 ** 0 to be 1 , as is common for programming languages. The numeric literals accepted include the digits 0 to 9 or any Unicode equivalent (code points with the Nd property). See the Unicode Standard for a complete list of code points with the Nd property. All numbers.Real types ( int and float ) also include the following operations: Operation Result math.trunc(x) x truncated to Integral round(x[, n]) x rounded to n digits, rounding half to even. If n is omitted, it defaults to 0. math.floor(x) the greatest Integral <= x math.ceil(x) the least Integral >= x For additional numeric operations see the math and cmath modules. Bitwise Operations on Integer Types ¶ Bitwise operations only make sense for integers. The result of bitwise operations is calculated as though carried out in two’s complement with an infinite number of sign bits. The priorities of the binary bitwise operations are all lower than the numeric operations and higher than the comparisons; the unary operation ~ has the same priority as the other unary numeric operations ( + and - ). This table lists the bitwise operations sorted in ascending priority: Operation Result Notes x | y bitwise or of x and y (4) x ^ y bitwise exclusive or of x and y (4) x & y bitwise and of x and y (4) x << n x shifted left by n bits (1)(2) x >> n x shifted right by n bits (1)(3) ~x the bits of x inverted Notes: Negative shift counts are illegal and cause a ValueError to be raised. A left shift by n bits is equivalent to multiplication by pow(2, n) . A right shift by n bits is equivalent to floor division by pow(2, n) . Performing these calculations with at least one extra sign extension bit in a finite two’s complement representation (a working bit-width of 1 + max(x.bit_length(), y.bit_length()) or more) is sufficient to get the same result as if there were an infinite number of sign bits. Additional Methods on Integer Types ¶ The int type implements the numbers.Integral abstract base class . In addition, it provides a few more methods: int. bit_length ( ) ¶ Return the number of bits necessary to represent an integer in binary, excluding the sign and leading zeros: >>> n = - 37 >>> bin ( n ) '-0b100101' >>> n . bit_length () 6 More precisely, if x is nonzero, then x.bit_length() is the unique positive integer k such that 2**(k-1) <= abs(x) < 2**k . Equivalently, when abs(x) is small enough to have a correctly rounded logarithm, then k = 1 + int(log(abs(x), 2)) . If x is zero, then x.bit_length() returns 0 . Equivalent to: def bit_length ( self ): s = bin ( self ) # binary representation: bin(-37) --> '-0b100101' s = s . lstrip ( '-0b' ) # remove leading zeros and minus sign return len ( s ) # len('100101') --> 6 Added in version 3.1. int. bit_count ( ) ¶ Return the number of ones in the binary representation of the absolute value of the integer. This is also known as the population count. Example: >>> n = 19 >>> bin ( n ) '0b10011' >>> n . bit_count () 3 >>> ( - n ) . bit_count () 3 Equivalent to: def bit_count ( self ): return bin ( self ) . count ( "1" ) Added in version 3.10. int. to_bytes ( length = 1 , byteorder = 'big' , * , signed = False ) ¶ Return an array of bytes representing an integer. >>> ( 1024 ) . to_bytes ( 2 , byteorder = 'big' ) b'\x04\x00' >>> ( 1024 ) . to_bytes ( 10 , byteorder = 'big' ) b'\x00\x00\x00\x00\x00\x00\x00\x00\x04\x00' >>> ( - 1024 ) . to_bytes ( 10 , byteorder = 'big' , signed = True ) b'\xff\xff\xff\xff\xff\xff\xff\xff\xfc\x00' >>> x = 1000 >>> x . to_bytes (( x . bit_length () + 7 ) // 8 , byteorder = 'little' ) b'\xe8\x03' The integer is represented using length bytes, and defaults to 1. An OverflowError is raised if the integer is not representable with the given number of bytes. The byteorder argument determines the byte order used to represent the integer, and defaults to "big" . If byteorder is "big" , the most significant byte is at the beginning of the byte array. If byteorder is "little" , the most significant byte is at the end of the byte array. The signed argument determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised. The default value for signed is False . The default values can be used to conveniently turn an integer into a single byte object: >>> ( 65 ) . to_bytes () b'A' However, when using the default arguments, don’t try to convert a value greater than 255 or you’ll get an OverflowError . Equivalent to: def to_bytes ( n , length = 1 , byteorder = 'big' , signed = False ): if byteorder == 'little' : order = range ( length ) elif byteorder == 'big' : order = reversed ( range ( length )) else : raise ValueError ( "byteorder must be either 'little' or 'big'" ) return bytes (( n >> i * 8 ) & 0xff for i in order ) Added in version 3.2. Changed in version 3.11: Added default argument values for length and byteorder . classmethod int. from_bytes ( bytes , byteorder = 'big' , * , signed = False ) ¶ Return the integer represented by the given array of bytes. >>> int . from_bytes ( b ' \x00\x10 ' , byteorder = 'big' ) 16 >>> int . from_bytes ( b ' \x00\x10 ' , byteorder = 'little' ) 4096 >>> int . from_bytes ( b ' \xfc\x00 ' , byteorder = 'big' , signed = True ) -1024 >>> int . from_bytes ( b ' \xfc\x00 ' , byteorder = 'big' , signed = False ) 64512 >>> int . from_bytes ([ 255 , 0 , 0 ], byteorder = 'big' ) 16711680 The argument bytes must either be a bytes-like object or an iterable producing bytes. The byteorder argument determines the byte order used to represent the integer, and defaults to "big" . If byteorder is "big" , the most significant byte is at the beginning of the byte array. If byteorder is "little" , the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. The signed argument indicates whether two’s complement is used to represent the integer. Equivalent to: def from_bytes ( bytes , byteorder = 'big' , signed = False ): if byteorder == 'little' : little_ordered = list ( bytes ) elif byteorder == 'big' : little_ordered = list ( reversed ( bytes )) else : raise ValueError ( "byteorder must be either 'little' or 'big'" ) n = sum ( b << i * 8 for i , b in enumerate ( little_ordered )) if signed and little_ordered and ( little_ordered [ - 1 ] & 0x80 ): n -= 1 << 8 * len ( little_ordered ) return n Added in version 3.2. Changed in version 3.11: Added default argument value for byteorder . int. as_integer_ratio ( ) ¶ Return a pair of integers whose ratio is equal to the original integer and has a positive denominator. The integer ratio of integers (whole numbers) is always the integer as the numerator and 1 as the denominator. Added in version 3.8. int. is_integer ( ) ¶ Returns True . Exists for duck type compatibility with float.is_integer() . Added in version 3.12. Additional Methods on Float ¶ The float type implements the numbers.Real abstract base class . float also has the following additional methods. classmethod float. from_number ( x ) ¶ Class method to return a floating-point number constructed from a number x . If the argument is an integer or a floating-point number, a floating-point number with the same value (within Python’s floating-point precision) is returned. If the argument is outside the range of a Python float, an OverflowError will be raised. For a general Python object x , float.from_number(x) delegates to x.__float__() . If __float__() is not defined then it falls back to __index__() . Added in version 3.14. float. as_integer_ratio ( ) ¶ Return a pair of integers whose ratio is exactly equal to the original float. The ratio is in lowest terms and has a positive denominator. Raises OverflowError on infinities and a ValueError on NaNs. float. is_integer ( ) ¶ Return True if the float instance is finite with integral value, and False otherwise: >>> ( - 2.0 ) . is_integer () True >>> ( 3.2 ) . is_integer () False Two methods support conversion to and from hexadecimal strings. Since Python’s floats are stored internally as binary numbers, converting a float to or from a decimal string usually involves a small rounding error. In contrast, hexadecimal strings allow exact representation and specification of floating-point numbers. This can be useful when debugging, and in numerical work. float. hex ( ) ¶ Return a representation of a floating-point number as a hexadecimal string. For finite floating-point numbers, this representation will always include a leading 0x and a trailing p and exponent. classmethod float. fromhex ( s ) ¶ Class method to return the float represented by a hexadecimal string s . The string s may have leading and trailing whitespace. Note that float.hex() is an instance method, while float.fromhex() is a class method. A hexadecimal string takes the form: [ sign ] [ '0x' ] integer [ '.' fraction ] [ 'p' exponent ] where the optional sign may by either + or - , integer and fraction are strings of hexadecimal digits, and exponent is a decimal integer with an optional leading sign. Case is not significant, and there must be at least one hexadecimal digit in either the integer or the fraction. This syntax is similar to the syntax specified in section 6.4.4.2 of the C99 standard, and also to the syntax used in Java 1.5 onwards. In particular, the output of float.hex() is usable as a hexadecimal floating-point literal in C or Java code, and hexadecimal strings produced by C’s %a format character or Java’s Double.toHexString are accepted by float.fromhex() . Note that the exponent is written in decimal rather than hexadecimal, and that it gives the power of 2 by which to multiply the coefficient. For example, the hexadecimal string 0x3.a7p10 represents the floating-point number (3 + 10./16 + 7./16**2) * 2.0**10 , or 3740.0 : >>> float . fromhex ( '0x3.a7p10' ) 3740.0 Applying the reverse conversion to 3740.0 gives a different hexadecimal string representing the same number: >>> float . hex ( 3740.0 ) '0x1.d380000000000p+11' Additional Methods on Complex ¶ The complex type implements the numbers.Complex abstract base class . complex also has the following additional methods. classmethod complex. from_number ( x ) ¶ Class method to convert a number to a complex number. For a general Python object x , complex.from_number(x) delegates to x.__complex__() . If __complex__() is not defined then it falls back to __float__() . If __float__() is not defined then it falls back to __index__() . Added in version 3.14. Hashing of numeric types ¶ For numbers x and y , possibly of different types, it’s a requirement that hash(x) == hash(y) whenever x == y (see the __hash__() method documentation for more details). For ease of implementation and efficiency across a variety of numeric types (including int , float , decimal.Decimal and fractions.Fraction ) Python’s hash for numeric types is based on a single mathematical function that’s defined for any rational number, and hence applies to all instances of int and fractions.Fraction , and all finite instances of float and decimal.Decimal . Essentially, this function is given by reduction modulo P for a fixed prime P . The value of P is made available to Python as the modulus attribute of sys.hash_info . CPython implementation detail: Currently, the prime used is P = 2**31 - 1 on machines with 32-bit C longs and P = 2**61 - 1 on machines with 64-bit C longs. Here are the rules in detail: If x = m / n is a nonnegative rational number and n is not divisible by P , define hash(x) as m * invmod(n, P) % P , where invmod(n, P) gives the inverse of n modulo P . If x = m / n is a nonnegative rational number and n is divisible by P (but m is not) then n has no inverse modulo P and the rule above doesn’t apply; in this case define hash(x) to be the constant value sys.hash_info.inf . If x = m / n is a negative rational number define hash(x) as -hash(-x) . If the resulting hash is -1 , replace it with -2 . The particular values sys.hash_info.inf and -sys.hash_info.inf are used as hash values for positive infinity or negative infinity (respectively). For a complex number z , the hash values of the real and imaginary parts are combined by computing hash(z.real) + sys.hash_info.imag * hash(z.imag) , reduced modulo 2**sys.hash_info.width so that it lies in range(-2**(sys.hash_info.width - 1), 2**(sys.hash_info.width - 1)) . Again, if the result is -1 , it’s replaced with -2 . To clarify the above rules, here’s some example Python code, equivalent to the built-in hash, for computing the hash of a rational number, float , or complex : import sys , math def hash_fraction ( m , n ): """Compute the hash of a rational number m / n. Assumes m and n are integers, with n positive. Equivalent to hash(fractions.Fraction(m, n)). """ P = sys . hash_info . modulus # Remove common factors of P. (Unnecessary if m and n already coprime.) while m % P == n % P == 0 : m , n = m // P , n // P if n % P == 0 : hash_value = sys . hash_info . inf else : # Fermat's Little Theorem: pow(n, P-1, P) is 1, so # pow(n, P-2, P) gives the inverse of n modulo P. hash_value = ( abs ( m ) % P ) * pow ( n , P - 2 , P ) % P if m < 0 : hash_value = - hash_value if hash_value == - 1 : hash_value = - 2 return hash_value def hash_float ( x ): """Compute the hash of a float x.""" if math . isnan ( x ): return object . __hash__ ( x ) elif math . isinf ( x ): return sys . hash_info . inf if x > 0 else - sys . hash_info . inf else : return hash_fraction ( * x . as_integer_ratio ()) def hash_complex ( z ): """Compute the hash of a complex number z.""" hash_value = hash_float ( z . real ) + sys . hash_info . imag * hash_float ( z . imag ) # do a signed reduction modulo 2**sys.hash_info.width M = 2 ** ( sys . hash_info . width - 1 ) hash_value = ( hash_value & ( M - 1 )) - ( hash_value & M ) if hash_value == - 1 : hash_value = - 2 return hash_value Boolean Type - bool ¶ Booleans represent truth values. The bool type has exactly two constant instances: True and False . The built-in function bool() converts any value to a boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above). For logical operations, use the boolean operators and , or and not . When applying the bitwise operators & , | , ^ to two booleans, they return a bool equivalent to the logical operations “and”, “or”, “xor”. However, the logical operators and , or and != should be preferred over & , | and ^ . Deprecated since version 3.12: The use of the bitwise inversion operator ~ is deprecated and will raise an error in Python 3.16. bool is a subclass of int (see Numeric Types — int, float, complex ). In many numeric contexts, False and True behave like the integers 0 and 1, respectively. However, relying on this is discouraged; explicitly convert using int() instead. Iterator Types ¶ Python supports a concept of iteration over containers. This is implemented using two distinct methods; these are used to allow user-defined classes to support iteration. Sequences, described below in more detail, always support the iteration methods. One method needs to be defined for container objects to provide iterable support: container. __iter__ ( ) ¶ Return an iterator object. The object is required to support the iterator protocol described below. If a container supports different types of iteration, additional methods can be provided to specifically request iterators for those iteration types. (An example of an object supporting multiple forms of iteration would be a tree structure which supports both breadth-first and depth-first traversal.) This method corresponds to the tp_iter slot of the type structure for Python objects in the Python/C API. The iterator objects themselves are required to support the following two methods, which together form the iterator protocol : iterator. __iter__ ( ) ¶ Return the iterator object itself. This is required to allow both containers and iterators to be used with the for and in statements. This method corresponds to the tp_iter slot of the type structure for Python objects in the Python/C API. iterator. __next__ ( ) ¶ Return the next item from the iterator . If there are no further items, raise the StopIteration exception. This method corresponds to the tp_iternext slot of the type structure for Python objects in the Python/C API. Python defines several iterator objects to support iteration over general and specific sequence types, dictionaries, and other more specialized forms. The specific types are not important beyond their implementation of the iterator protocol. Once an iterator’s __next__() method raises StopIteration , it must continue to do so on subsequent calls. Implementations that do not obey this property are deemed broken. Generator Types ¶ Python’s generator s provide a convenient way to implement the iterator protocol. If a container object’s __iter__() method is implemented as a generator, it will automatically return an iterator object (technically, a generator object) supplying the __iter__() and __next__() methods. More information about generators can be found in the documentation for the yield expression . Sequence Types — list , tuple , range ¶ There are three basic sequence types: lists, tuples, and range objects. Additional sequence types tailored for processing of binary data and text strings are described in dedicated sections. Common Sequence Operations ¶ The operations in the following table are supported by most sequence types, both mutable and immutable. The collections.abc.Sequence ABC is provided to make it easier to correctly implement these operations on custom sequence types. This table lists the sequence operations sorted in ascending priority. In the table, s and t are sequences of the same type, n , i , j and k are integers and x is an arbitrary object that meets any type and value restrictions imposed by s . The in and not in operations have the same priorities as the comparison operations. The + (concatenation) and * (repetition) operations have the same priority as the corresponding numeric operations. [ 3 ] Operation Result Notes x in s True if an item of s is equal to x , else False (1) x not in s False if an item of s is equal to x , else True (1) s + t the concatenation of s and t (6)(7) s * n or n * s equivalent to adding s to itself n times (2)(7) s[i] i th item of s , origin 0 (3)(8) s[i:j] slice of s from i to j (3)(4) s[i:j:k] slice of s from i to j with step k (3)(5) len(s) length of s min(s) smallest item of s max(s) largest item of s Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length. (For full details see Comparisons in the language reference.) Forward and reversed iterators over mutable sequences access values using an index. That index will continue to march forward (or backward) even if the underlying sequence is mutated. The iterator terminates only when an IndexError or a StopIteration is encountered (or when the index drops below zero). Notes: While the in and not in operations are used only for simple containment testing in the general case, some specialised sequences (such as str , bytes and bytearray ) also use them for subsequence testing: >>> "gg" in "eggs" True Values of n less than 0 are treated as 0 (which yields an empty sequence of the same type as s ). Note that items in the sequence s are not copied; they are referenced multiple times. This often haunts new Python programmers; consider: >>> lists = [[]] * 3 >>> lists [[], [], []] >>> lists [ 0 ] . append ( 3 ) >>> lists [[3], [3], [3]] What has happened is that [[]] is a one-element list containing an empty list, so all three elements of [[]] * 3 are references to this single empty list. Modifying any of the elements of lists modifies this single list. You can create a list of different lists this way: >>> lists = [[] for i in range ( 3 )] >>> lists [ 0 ] . append ( 3 ) >>> lists [ 1 ] . append ( 5 ) >>> lists [ 2 ] . append ( 7 ) >>> lists [[3], [5], [7]] Further explanation is available in the FAQ entry How do I create a multidimensional list? . If i or j is negative, the index is relative to the end of sequence s : len(s) + i or len(s) + j is substituted. But note that -0 is still 0 . The slice of s from i to j is defined as the sequence of items with index k such that i <= k < j . If i is omitted or None , use 0 . If j is omitted or None , use len(s) . If i or j is less than -len(s) , use 0 . If i or j is greater than len(s) , use len(s) . If i is greater than or equal to j , the slice is empty. The slice of s from i to j with step k is defined as the sequence of items with index x = i + n*k such that 0 <= n < (j-i)/k . In other words, the indices are i , i+k , i+2*k , i+3*k and so on, stopping when j is reached (but never including j ). When k is positive, i and j are reduced to len(s) if they are greater. When k is negative, i and j are reduced to len(s) - 1 if they are greater. If i or j are omitted or None , they become “end” values (which end depends on the sign of k ). Note, k cannot be zero. If k is None , it is treated like 1 . Concatenating immutable sequences always results in a new object. This means that building up a sequence by repeated concatenation will have a quadratic runtime cost in the total sequence length. To get a linear runtime cost, you must switch to one of the alternatives below: if concatenating str objects, you can build a list and use str.join() at the end or else write to an io.StringIO instance and retrieve its value when complete if concatenating bytes objects, you can similarly use bytes.join() or io.BytesIO , or you can do in-place concatenation with a bytearray object. bytearray objects are mutable and have an efficient overallocation mechanism if concatenating tuple objects, extend a list instead for other types, investigate the relevant class documentation Some sequence types (such as range ) only support item sequences that follow specific patterns, and hence don’t support sequence concatenation or repetition. An IndexError is raised if i is outside the sequence range. Sequence Methods Sequence types also support the following methods: sequence. count ( value , / ) ¶ Return the total number of occurrences of value in sequence . sequence. index ( value[, start[, stop] ) ¶ Return the index of the first occurrence of value in sequence . Raises ValueError if value is not found in sequence . The start or stop arguments allow for efficient searching of subsections of the sequence, beginning at start and ending at stop . This is roughly equivalent to start + sequence[start:stop].index(value) , only without copying any data. Caution Not all sequence types support passing the start and stop arguments. Immutable Sequence Types ¶ The only operation that immutable sequence types generally implement that is not also implemented by mutable sequence types is support for the hash() built-in. This support allows immutable sequences, such as tuple instances, to be used as dict keys and stored in set and frozenset instances. Attempting to hash an immutable sequence that contains unhashable values will result in TypeError . Mutable Sequence Types ¶ The operations in the following table are defined on mutable sequence types. The collections.abc.MutableSequence ABC is provided to make it easier to correctly implement these operations on custom sequence types. In the table s is an instance of a mutable sequence type, t is any iterable object and x is an arbitrary object that meets any type and value restrictions imposed by s (for example, bytearray only accepts integers that meet the value restriction 0 <= x <= 255 ). Operation Result Notes s[i] = x item i of s is replaced by x del s[i] removes item i of s s[i:j] = t slice of s from i to j is replaced by the contents of the iterable t del s[i:j] removes the elements of s[i:j] from the list (same as s[i:j] = [] ) s[i:j:k] = t the elements of s[i:j:k] are replaced by those of t (1) del s[i:j:k] removes the elements of s[i:j:k] from the list s += t extends s with the contents of t (for the most part the same as s[len(s):len(s)] = t ) s *= n updates s with its contents repeated n times (2) Notes: If k is not equal to 1 , t must have the same length as the slice it is replacing. The value n is an integer, or an object implementing __index__() . Zero and negative values of n clear the sequence. Items in the sequence are not copied; they are referenced multiple times, as explained for s * n under Common Sequence Operations . Mutable Sequence Methods Mutable sequence types also support the following methods: sequence. append ( value , / ) ¶ Append value to the end of the sequence This is equivalent to writing seq[len(seq):len(seq)] = [value] . sequence. clear ( ) ¶ Added in version 3.3. Remove all items from sequence . This is equivalent to writing del sequence[:] . sequence. copy ( ) ¶ Added in version 3.3. Create a shallow copy of sequence . This is equivalent to writing sequence[:] . Hint The copy() method is not part of the MutableSequence ABC , but most concrete mutable sequence types provide it. sequence. extend ( iterable , / ) ¶ Extend sequence with the contents of iterable . For the most part, this is the same as writing seq[len(seq):len(seq)] = iterable . sequence. insert ( index , value , / ) ¶ Insert value into sequence at the given index . This is equivalent to writing sequence[index:index] = [value] . sequence. pop ( index = -1 , / ) ¶ Retrieve the item at index and also removes it from sequence . By default, the last item in sequence is removed and returned. sequence. remove ( value , / ) ¶ Remove the first item from sequence where sequence[i] == value . Raises ValueError if value is not found in sequence . sequence. reverse ( ) ¶ Reverse the items of sequence in place. This method maintains economy of space when reversing a large sequence. To remind users that it operates by side-effect, it returns None . Lists ¶ Lists are mutable sequences, typically used to store collections of homogeneous items (where the precise degree of similarity will vary by application). class list ( iterable = () , / ) ¶ Lists may be constructed in several ways: Using a pair of square brackets to denote the empty list: [] Using square brackets, separating items with commas: [a] , [a, b, c] Using a list comprehension: [x for x in iterable] Using the type constructor: list() or list(iterable) The constructor builds a list whose items are the same and in the same order as iterable ’s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If iterable is already a list, a copy is made and returned, similar to iterable[:] . For example, list('abc') returns ['a', 'b', 'c'] and list( (1, 2, 3) ) returns [1, 2, 3] . If no argument is given, the constructor creates a new empty list, [] . Many other operations also produce lists, including the sorted() built-in. Lists implement all of the common and mutable sequence operations. Lists also provide the following additional method: sort ( * , key = None , reverse = False ) ¶ This method sorts the list in place, using only < comparisons between items. Exceptions are not suppressed - if any comparison operations fail, the entire sort operation will fail (and the list will likely be left in a partially modified state). sort() accepts two arguments that can only be passed by keyword ( keyword-only arguments ): key specifies a function of one argument that is used to extract a comparison key from each list element (for example, key=str.lower ). The key corresponding to each item in the list is calculated once and then used for the entire sorting process. The default value of None means that list items are sorted directly without calculating a separate key value. The functools.cmp_to_key() utility is available to convert a 2.x style cmp function to a key function. reverse is a boolean value. If set to True , then the list elements are sorted as if each comparison were reversed. This method modifies the sequence in place for economy of space when sorting a large sequence. To remind users that it operates by side effect, it does not return the sorted sequence (use sorted() to explicitly request a new sorted list instance). The sort() method is guaranteed to be stable. A sort is stable if it guarantees not to change the relative order of elements that compare equal — this is helpful for sorting in multiple passes (for example, sort by department, then by salary grade). For sorting examples and a brief sorting tutorial, see Sorting Techniques . CPython implementation detail: While a list is being sorted, the effect of attempting to mutate, or even inspect, the list is undefined. The C implementation of Python makes the list appear empty for the duration, and raises ValueError if it can detect that the list has been mutated during a sort. Thread safety Reading a single element from a list is atomic : lst [ i ] # list.__getitem__ The following methods traverse the list and use atomic reads of each item to perform their function. That means that they may return results affected by concurrent modifications: item in lst lst . index ( item ) lst . count ( item ) All of the above methods/operations are also lock-free. They do not block concurrent modifications. Other operations that hold a lock will not block these from observing intermediate states. All other operations from here on block using the per-object lock. Writing a single item via lst[i] = x is safe to call from multiple threads and will not corrupt the list. The following operations return new objects and appear atomic to other threads: lst1 + lst2 # concatenates two lists into a new list x * lst # repeats lst x times into a new list lst . copy () # returns a shallow copy of the list Methods that only operate on a single elements with no shifting required are atomic : lst . append ( x ) # append to the end of the list, no shifting required lst . pop () # pop element from the end of the list, no shifting required The clear() method is also atomic . Other threads cannot observe elements being removed. The sort() method is not atomic . Other threads cannot observe intermediate states during sorting, but the list appears empty for the duration of the sort. The following operations may allow lock-free operations to observe intermediate states since they modify multiple elements in place: lst . insert ( idx , item ) # shifts elements lst . pop ( idx ) # idx not at the end of the list, shifts elements lst *= x # copies elements in place The remove() method may allow concurrent modifications since element comparison may execute arbitrary Python code (via __eq__() ). extend() is safe to call from multiple threads. However, its guarantees depend on the iterable passed to it. If it is a list , a tuple , a set , a frozenset , a dict or a dictionary view object (but not their subclasses), the extend operation is safe from concurrent modifications to the iterable. Otherwise, an iterator is created which can be concurrently modified by another thread. The same applies to inplace concatenation of a list with other iterables when using lst += iterable . Similarly, assigning to a list slice with lst[i:j] = iterable is safe to call from multiple threads, but iterable is only locked when it is also a list (but not its subclasses). Operations that involve multiple accesses, as well as iteration, are never atomic. For example: # NOT atomic: read-modify-write lst [ i ] = lst [ i ] + 1 # NOT atomic: check-then-act if lst : item = lst . pop () # NOT thread-safe: iteration while modifying for item in lst : process ( item ) # another thread may modify lst Consider external synchronization when sharing list instances across threads. See Python support for free threading for more information. Tuples ¶ Tuples are immutable sequences, typically used to store collections of heterogeneous data (such as the 2-tuples produced by the enumerate() built-in). Tuples are also used for cases where an immutable sequence of homogeneous data is needed (such as allowing storage in a set or dict instance). class tuple ( iterable = () , / ) ¶ Tuples may be constructed in a number of ways: Using a pair of parentheses to denote the empty tuple: () Using a trailing comma for a singleton tuple: a, or (a,) Separating items with commas: a, b, c or (a, b, c) Using the tuple() built-in: tuple() or tuple(iterable) The constructor builds a tuple whose items are the same and in the same order as iterable ’s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If iterable is already a tuple, it is returned unchanged. For example, tuple('abc') returns ('a', 'b', 'c') and tuple( [1, 2, 3] ) returns (1, 2, 3) . If no argument is given, the constructor creates a new empty tuple, () . Note that it is actually the comma which makes a tuple, not the parentheses. The parentheses are optional, except in the empty tuple case, or when they are needed to avoid syntactic ambiguity. For example, f(a, b, c) is a function call with three arguments, while f((a, b, c)) is a function call with a 3-tuple as the sole argument. Tuples implement all of the common sequence operations. For heterogeneous collections of data where access by name is clearer than access by index, collections.namedtuple() may be a more appropriate choice than a simple tuple object. Ranges ¶ The range type represents an immutable sequence of numbers and is commonly used for looping a specific number of times in for loops. class range ( stop , / ) ¶ class range ( start , stop , step = 1 , / ) The arguments to the range constructor must be integers (either built-in int or any object that implements the __index__() special method). If the step argument is omitted, it defaults to 1 . If the start argument is omitted, it defaults to 0 . If step is zero, ValueError is raised. For a positive step , the contents of a range r are determined by the formula r[i] = start + step*i where i >= 0 and r[i] < stop . For a negative step , the contents of the range are still determined by the formula r[i] = start + step*i , but the constraints are i >= 0 and r[i] > stop . A range object will be empty if r[0] does not meet the value constraint. Ranges do support negative indices, but these are interpreted as indexing from the end of the sequence determined by the positive indices. Ranges containing absolute values larger than sys.maxsize are permitted but some features (such as len() ) may raise OverflowError . Range examples: >>> list ( range ( 10 )) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> list ( range ( 1 , 11 )) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> list ( range ( 0 , 30 , 5 )) [0, 5, 10, 15, 20, 25] >>> list ( range ( 0 , 10 , 3 )) [0, 3, 6, 9] >>> list ( range ( 0 , - 10 , - 1 )) [0, -1, -2, -3, -4, -5, -6, -7, -8, -9] >>> list ( range ( 0 )) [] >>> list ( range ( 1 , 0 )) [] Ranges implement all of the common sequence operations except concatenation and repetition (due to the fact that range objects can only represent sequences that follow a strict pattern and repetition and concatenation will usually violate that pattern). start ¶ The value of the start parameter (or 0 if the parameter was not supplied) stop ¶ The value of the stop parameter step ¶ The value of the step parameter (or 1 if the parameter was not supplied) The advantage of the range type over a regular list or tuple is that a range object will always take the same (small) amount of memory, no matter the size of the range it represents (as it only stores the start , stop and step values, calculating individual items and subranges as needed). Range objects implement the collections.abc.Sequence ABC, and provide features such as containment tests, element index lookup, slicing and support for negative indices (see Sequence Types — list, tuple, range ): >>> r = range ( 0 , 20 , 2 ) >>> r range(0, 20, 2) >>> 11 in r False >>> 10 in r True >>> r . index ( 10 ) 5 >>> r [ 5 ] 10 >>> r [: 5 ] range(0, 10, 2) >>> r [ - 1 ] 18 Testing range objects for equality with == and != compares them as sequences. That is, two range objects are considered equal if they represent the same sequence of values. (Note that two range objects that compare equal might have different start , stop and step attributes, for example range(0) == range(2, 1, 3) or range(0, 3, 2) == range(0, 4, 2) .) Changed in version 3.2: Implement the Sequence ABC. Support slicing and negative indices. Test int objects for membership in constant time instead of iterating through all items. Changed in version 3.3: Define ‘==’ and ‘!=’ to compare range objects based on the sequence of values they define (instead of comparing based on object identity). Added the start , stop and step attributes. See also The linspace recipe shows how to implement a lazy version of range suitable for floating-point applications.

Strings are immutable sequences of Unicode code points. String literals are written in a variety of ways: Single quotes: 'allows embedded "double" quotes' Double quotes: "allows embedded 'single' quotes" Triple quoted: '''Three single quotes''' , """Three double quotes""" Triple quoted strings may span multiple lines - all associated whitespace will be included in the string literal. String literals that are part of a single expression and have only whitespace between them will be implicitly converted to a single string literal. That is, ("spam " "eggs") == "spam eggs" . See String and Bytes literals for more about the various forms of string literal

Para gerar a documentação em português siga os passos a seguir (usaremos o Django como exemplo): 1 - Conforme a documentação do Transifex , será preciso criar um arquivo chamado .transifexrc na raiz do seu diretório pessoal (ex.: /home/user/.transifexrc ) contendo seu login e senha no Transifex: [https://www.transifex.com] username = user token = password = passw0rd hostname = https://www.transifex.com 2 - Será preciso baixar os repositórios e instalar algumas bibliotecas, para isso é recomendado criar uma pasta de trabalho: mkdir ~/traducoes/django-br && cd ~/traducoes/django-br 3 - Faça o clone do repositório no GitHub: git clone https://github.com/django/django.git 4 - Faça também o clone do repositório contendo as traduções do Django (como as traduções consomem muito espaço, elas foram movidas para um repositório separado): git clone https://github.com/django/django-docs-translations.git 5 - Para gerar a documentação em português, nós vamos trabalhar dentro do diretório django-docs-translations : cd django-docs-translations/ 6 - Existem várias traduções disponíveis, uma para cada versão do Django, nesse exemplo nós vamos gerar a documentação para a versão 1.10.x: git checkout stable/1.10.x 7 - Para a instalação das bibliotecas, é recomendado também criar e ativar um virtualenv: python -m venv .django-br source .django-br/bin/activate 6 - Para gerar a documentação, o Django utiliza uma biblioteca chamada Sphinx, você pode instalá-la rodando o comando abaixo: pip install sphinx 7 - Para baixar as últimas traduções do site Transifex, nós vamos precisar instalar também a biblioteca Transifex-Client : pip install transifex-client 8 - Com o Transifex-Client instalado e com o arquivo .transifexrc configurado na raiz do seu diretório pessoal, será possível executar o comando abaixo para baixar as traduções do Transifex: tx pull -f -l pt_BR 9 - Com o download das traduções concluído, agora é preciso executar o comando 'make translations' para compilá-las: make translations 10 - Também é necessário criar um link simbólico para que o Sphinx gere a documentação utilizando os arquivos baixados e compilados por você (ao invés dos arquivos padrão no repositório do Django): ln -s ~/traducoes/django-br/django-docs-translations/translations/ ~/traducoes/django-br/django/docs/locale 11 - Agora saia do repositório django-docs-translations e vá para o repositório django, onde vamos encontrar um diretório chamado docs . É dentro desse diretório que vamos poder gerar a documentação: cd ../django/docs/ 12 - Dentro do diretório docs do repositório do Django, após executar os passos acima, rode o comando abaixo para que o Sphinx gere a documentação em português: make html LANGUAGE=pt_BR 13 - Como medida de segurança, eu sugiro excluir o arquivo ~/.transifexrc do seu home ou apagar a senha contida dentro dele já que o Transifex não oferece autenticação via tokens (ainda): rm ~/.transifexrc 14 - Ao final do processo, um novo diretório _build é criado e dentro desse diretório é possível encontrar também o diretório html contendo os arquivos gerados pelo Sphinx. Para visualizar a documentação entre em _build/html/ : cd _build/html/ A página principal da documentação é a index.html , clique duas vezes nesse arquivo para que ele seja aberto no seu browser. Clique nos links para navegar pela documentação, embora sejam links html, todo o conteúdo está contido dentro da pasta _build e portanto disponível offline. O Sphinx permite ainda gerar a documentação em outros formatos como .pdf . Dicas de tradução Nesta seção apresentamos agumas dicas de tradução. Atenção com palavras de grafia parecida Model: Modelo -- Classe que representa uma tabela. Module: Módulo -- Módulo Python, e dentro do Django ainda pode ser o nome de uma Django "app". Cuidado com neologismo A maioria dos termos de computação vem do inglês. E muitas vezes usamos os termos em inglês sem nos dar conta, ou pior, usamos uma tradução cujo o sentido da palavra em português é outro. Adotando a linguagem neutra de gênero Tente usar a linguagem neutra de gênero, pois é uma forma inclusiva de comunicação. Usar 'x' ou '@' no final de termos masculinos ou femininos não é inclusivo e não é reconhecido por leitores de tela. Tente usar uma linguagem que se refira à pessoas, não somente ao masculino ou feminino. Por exemplo: Se você está interessado em contribuir entre em contato conosco Use ao invés disso: Caso haja interesse em contribuir entre em contato conosco Para saber mais sobre a linguagem neutra de gênero você poder ler este artigo da ThoughtWorks Brasil: Adotando a linguagem neutra de gênero Cuidado com os artigos Em inglês as palavras não possuem gênero, portando tenha atenção quanto a concordância dos artigos ao realizar a tradução: Or use a common ancestor to hold the :class:`~django.db.models.AutoField` alguém poderia traduzir como usando o artigo "o" referindo-se ao "autoField": Ou use um acestral comum para manter o :class:`~django.db.models.AutoField` Mas não seria correto. Talvez para uma leitura menos atenta fique até estranho, o que é bom pois chamará atenção se usarmos um artigo feminino neste caso. Ou use um acestral comum para manter a :class:`~django.db.models.AutoField` quer dizer, "ou use um acestral comum para a manter a classe ~django.db.models.AutoField" Depois do texto renderizado, a diretiva :class: não é mostrada, e usar o artigo correto ajuda a lembrar que referenciamos uma classe ou método por exemplo. Não tente explicar mais que na autoria original Cuidado ao achar que um texto em inglês não está bem explicado, ou falta detalhes. Você pode ter razão, e a solução é sugerir melhorias no texto original. Se ao invés disso, tentar escrever um texto melhor na tradução, além do problema raiz persistir, pode acontecer de estar sendo repetitivo. O erro no texto original pode existir, mas antes de afirmá-lo, procure ler o contexto todo e entender se aquele detalhe ou explicação deveria estar ali, ou já foi comentado em outra seção, ou se é realmente papel do texto explicar em detalhes tal condição. Glossário de tradução Este glossário tem como objetivo criar uma consistência de tradução entre os projetos: Sobre Este site busca reunir todo o conteúdo produzido e traduzido pela comunidade brasileira bem como informações relevantes em relação a mesma.

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Status and Lifecycle | DevCycle Docs Skip to main content Home SDKs APIs Management API Bucketing API Integrations CLI / MCP Best Practices Community Blog Discord Search Sign Up Home Getting Started Essentials DevCycle Overview Key Features System Architecture Feature Hierarchy Feature Types Platform Feature Flags Features Variables and Variations Targeting Status and Lifecycle Stale Feature Notifications Experimentation Account Management Security and Guardrails Testing and QA Extras Examples Platform Feature Flags Status and Lifecycle On this page Feature Status and Lifecycle Management In DevCycle, Features have Statuses that indicate their current position in the feature lifecycle. Statuses provide a clear, at-a-glance understanding of where a Feature is in its development, release, and cleanup process. Each Status belongs to a Status Category , which defines how the Feature behaves, what actions are allowed, and how it is displayed across the dashboard. Statuses ​ Every Feature in DevCycle always has one Status , which determines its lifecycle stage. By default, DevCycle provides a set of predefined Statuses aligned to core lifecycle categories. The default Statuses are: Development Live Completed Archived In addition to the default Statuses, teams can define custom Statuses within their Project settings. This allows teams to better align Feature lifecycle tracking with their internal development and release processes while preserving DevCycle's lifecycle guarantees. Each custom Status inherits the behavior of their Category. Status changes are not automatic and are always managed explicitly by the user. Status Categories ​ Statuses are grouped into Categories , which define shared lifecycle behavior. Development ​ This Category represents Features that are actively being built, tested, or prepared for release. By default, new Features are created with the Development Status. While a Feature is in Development, all Targeting rules and Variations remain editable. This stage is typically used while work is ongoing and before a Feature is considered ready for a broader release. Below are some examples of different Statuses that would make sense in the Development Category: In Development Pending Design QA Internal Testing Live ​ The Live Category represents Features that are actively running in production or being exposed to users. While a Feature is Live, all Targeting rules and Variations remain editable. Below are some examples of different Statuses that would make sense in the Live Category: Beta Ramping In Production Live Experiment Completed ​ The Completed Category represents Features that have reached the end of active development and rollout. A Feature may be considered Completed once it has been tested, approved, and is fully released, or when no further targeting changes are expected. When a Feature is moved into a Status within the Completed Category, it enters a semi-read-only state : A single final (release) Variation must be selected All Environments will serve this Variation to all users Targeting rules are replaced with an "All users" rule New targeting rules and Variations cannot be added Variable values may still be edited Environments can still be toggled on or off When using the CLI to generate TypeScript types, Variables belonging to a Feature in the Completed Category will be marked as deprecated . Below are some examples of different Statuses that would make sense in the Completed Category: Ready for Cleanup All Users Enabled Stable Release Cleanup Checklist ​ Upon entering a Completed Status, a cleanup checklist is shown for each Variable associated with the Feature. This checklist helps teams determine when it is safe to remove Variables from their codebase or archive them. If a Variable is still referenced in code or evaluated in production, removing it may result in default values being served. If Code References are enabled, additional context will be provided to assist with cleanup. Archived ​ The Archived Category represents the terminal lifecycle state for Features. This Category and Status cannot be edited or changed. A Feature should be archived once it has been fully cleaned up and its Variables have been removed from the codebase. When a Feature is Archived: It becomes fully read-only It is hidden from standard dashboard views Audit Logs remain accessible for historical reference Metrics & Reach data will not be visible on the dashboard for Archived features Archiving Features helps keep both your dashboard and codebase clean while preserving valuable lifecycle history. Note: Feature deletion still exists, but should only be used for mistakes. Deleting a Feature permanently removes it and its Audit Log. Archived Features retain historical data that may be used for future reporting and analysis. Changing Status ​ Moving a Feature to Completed ​ When a Feature is moved into the Completed Category: A final Variation must be selected All Environments serve that Variation to all users Existing Environment statuses are preserved Targeting rules are replaced with a single "All users" rule Additional Variations and targeting rules are locked Reverting to Development or Live ​ Features in the Completed Category can be reverted back to an earlier Status. When reverting: Previous Variations become available again Changes made to Variable values while Completed are retained Prior targeting rules are not restored and must be reconfigured Viewing Features by Status (Kanban View) ​ On the Feature list page, users can switch between a List view and a Kanban-style view that displays Features grouped by their current Status, allowing teams to quickly visualize progress across the Feature lifecycle. In this view: Each column represents a Feature Status Each column header includes a total count of Features in each Status Features appear as cards within the column matching their current Status, and can be sorted differently by selected criteria Columns are ordered based on the Status order defined in Project Settings Status colors are reflected in the column headers for quick visual scanning This view is intended for high-level lifecycle tracking and workflow management. Selecting a Feature card opens the Feature detail view for configuration, targeting, and Variable management. Managing Statuses ​ Statuses are managed at the Project level and apply to all Features within that Project. Each Project starts with a default set of Statuses aligned to DevCycle's lifecycle categories. Teams may customize these Statuses to better reflect their internal workflows. Project Settings ​ Statuses can be viewed and managed from the Project Settings page under the Feature Statuses section. From this page, users can: View all Statuses grouped by Category Create new custom Statuses within supported Categories Edit existing Status names (Note: each Status must have a unique key) Reorder Statuses within a Category Assign colors to Statuses for quick visual identification Add a description to provide context behind what a Status represents Select the default Status applied when a new Feature is created Changes made in Project Settings take effect immediately and apply across the Project. Status Categories and Rules ​ Statuses must belong to one of DevCycle's predefined Categories. The following rules apply: New Categories cannot be created Each Category must contain at least one Status The last remaining Status in a Category cannot be deleted Status labels and ordering within a Category can be modified Permissions for Status Changes ​ Permission Rules ​ When permissions are enabled: Statuses in the Development and Live Categories can be applied by any user with access to the Project Statuses in the Completed and Archived Categories can only be applied by users with the Publisher permission Only Publishers can create, and modify Feature Statuses in the Project Settings Edit this page Last updated on Jan 9, 2026 Previous EdgeDB (Stored Custom Properties) Next Stale Feature Notifications Statuses Status Categories Development Live Completed Archived Changing Status Moving a Feature to Completed Reverting to Development or Live Viewing Features by Status (Kanban View) Managing Statuses Project Settings Permissions for Status Changes DevCycle Dashboard Blog Privacy Policy Twitter Discord GitHub Copyright © 2026 DevCycle.

Status and Lifecycle | DevCycle Docs Skip to main content Home SDKs APIs Management API Bucketing API Integrations CLI / MCP Best Practices Community Blog Discord Search Sign Up Home Getting Started Essentials DevCycle Overview Key Features System Architecture Feature Hierarchy Feature Types Platform Feature Flags Features Variables and Variations Targeting Status and Lifecycle Stale Feature Notifications Experimentation Account Management Security and Guardrails Testing and QA Extras Examples Platform Feature Flags Status and Lifecycle On this page Feature Status and Lifecycle Management In DevCycle, Features have Statuses that indicate their current position in the feature lifecycle. Statuses provide a clear, at-a-glance understanding of where a Feature is in its development, release, and cleanup process. Each Status belongs to a Status Category , which defines how the Feature behaves, what actions are allowed, and how it is displayed across the dashboard. Statuses ​ Every Feature in DevCycle always has one Status , which determines its lifecycle stage. By default, DevCycle provides a set of predefined Statuses aligned to core lifecycle categories. The default Statuses are: Development Live Completed Archived In addition to the default Statuses, teams can define custom Statuses within their Project settings. This allows teams to better align Feature lifecycle tracking with their internal development and release processes while preserving DevCycle's lifecycle guarantees. Each custom Status inherits the behavior of their Category. Status changes are not automatic and are always managed explicitly by the user. Status Categories ​ Statuses are grouped into Categories , which define shared lifecycle behavior. Development ​ This Category represents Features that are actively being built, tested, or prepared for release. By default, new Features are created with the Development Status. While a Feature is in Development, all Targeting rules and Variations remain editable. This stage is typically used while work is ongoing and before a Feature is considered ready for a broader release. Below are some examples of different Statuses that would make sense in the Development Category: In Development Pending Design QA Internal Testing Live ​ The Live Category represents Features that are actively running in production or being exposed to users. While a Feature is Live, all Targeting rules and Variations remain editable. Below are some examples of different Statuses that would make sense in the Live Category: Beta Ramping In Production Live Experiment Completed ​ The Completed Category represents Features that have reached the end of active development and rollout. A Feature may be considered Completed once it has been tested, approved, and is fully released, or when no further targeting changes are expected. When a Feature is moved into a Status within the Completed Category, it enters a semi-read-only state : A single final (release) Variation must be selected All Environments will serve this Variation to all users Targeting rules are replaced with an "All users" rule New targeting rules and Variations cannot be added Variable values may still be edited Environments can still be toggled on or off When using the CLI to generate TypeScript types, Variables belonging to a Feature in the Completed Category will be marked as deprecated . Below are some examples of different Statuses that would make sense in the Completed Category: Ready for Cleanup All Users Enabled Stable Release Cleanup Checklist ​ Upon entering a Completed Status, a cleanup checklist is shown for each Variable associated with the Feature. This checklist helps teams determine when it is safe to remove Variables from their codebase or archive them. If a Variable is still referenced in code or evaluated in production, removing it may result in default values being served. If Code References are enabled, additional context will be provided to assist with cleanup. Archived ​ The Archived Category represents the terminal lifecycle state for Features. This Category and Status cannot be edited or changed. A Feature should be archived once it has been fully cleaned up and its Variables have been removed from the codebase. When a Feature is Archived: It becomes fully read-only It is hidden from standard dashboard views Audit Logs remain accessible for historical reference Metrics & Reach data will not be visible on the dashboard for Archived features Archiving Features helps keep both your dashboard and codebase clean while preserving valuable lifecycle history. Note: Feature deletion still exists, but should only be used for mistakes. Deleting a Feature permanently removes it and its Audit Log. Archived Features retain historical data that may be used for future reporting and analysis. Changing Status ​ Moving a Feature to Completed ​ When a Feature is moved into the Completed Category: A final Variation must be selected All Environments serve that Variation to all users Existing Environment statuses are preserved Targeting rules are replaced with a single "All users" rule Additional Variations and targeting rules are locked Reverting to Development or Live ​ Features in the Completed Category can be reverted back to an earlier Status. When reverting: Previous Variations become available again Changes made to Variable values while Completed are retained Prior targeting rules are not restored and must be reconfigured Viewing Features by Status (Kanban View) ​ On the Feature list page, users can switch between a List view and a Kanban-style view that displays Features grouped by their current Status, allowing teams to quickly visualize progress across the Feature lifecycle. In this view: Each column represents a Feature Status Each column header includes a total count of Features in each Status Features appear as cards within the column matching their current Status, and can be sorted differently by selected criteria Columns are ordered based on the Status order defined in Project Settings Status colors are reflected in the column headers for quick visual scanning This view is intended for high-level lifecycle tracking and workflow management. Selecting a Feature card opens the Feature detail view for configuration, targeting, and Variable management. Managing Statuses ​ Statuses are managed at the Project level and apply to all Features within that Project. Each Project starts with a default set of Statuses aligned to DevCycle's lifecycle categories. Teams may customize these Statuses to better reflect their internal workflows. Project Settings ​ Statuses can be viewed and managed from the Project Settings page under the Feature Statuses section. From this page, users can: View all Statuses grouped by Category Create new custom Statuses within supported Categories Edit existing Status names (Note: each Status must have a unique key) Reorder Statuses within a Category Assign colors to Statuses for quick visual identification Add a description to provide context behind what a Status represents Select the default Status applied when a new Feature is created Changes made in Project Settings take effect immediately and apply across the Project. Status Categories and Rules ​ Statuses must belong to one of DevCycle's predefined Categories. The following rules apply: New Categories cannot be created Each Category must contain at least one Status The last remaining Status in a Category cannot be deleted Status labels and ordering within a Category can be modified Permissions for Status Changes ​ Permission Rules ​ When permissions are enabled: Statuses in the Development and Live Categories can be applied by any user with access to the Project Statuses in the Completed and Archived Categories can only be applied by users with the Publisher permission Only Publishers can create, and modify Feature Statuses in the Project Settings Edit this page Last updated on Jan 9, 2026 Previous EdgeDB (Stored Custom Properties) Next Stale Feature Notifications Statuses Status Categories Development Live Completed Archived Changing Status Moving a Feature to Completed Reverting to Development or Live Viewing Features by Status (Kanban View) Managing Statuses Project Settings Permissions for Status Changes DevCycle Dashboard Blog Privacy Policy Twitter Discord GitHub Copyright © 2026 DevCycle.

Perl Weekly Issue #755 - 2026-01-12 - Does TIOBE help Perl? Perl Weekly Issue #755 - 2026-01-12 - Does TIOBE help Perl? latest | archive | edited by Gabor Szabo This edition was made possible by the supporters of our cause . Don't miss the next issue! Enter your e-mail: --> --> Hi there! Dave Cross has an article showing position of Perl on the TIOBE index. As I don't see any up-tick in new subscribers to the Perl Weekly nor do I see any increase in the MetaCPAN activity I keep track of, I doubt that the changes in the position reflects actual changes in the market. However I wonder, could the TIOBE index have an impact on the interest in Perl? How and when could we see that? Speaking of the MetaCPAN report , I'd love if someone sent a PR to the Perl Weekly that would generates same graphs using these numbers. Here is the issue for it. And another comment related to those stats. I just noticed that the No CI column went up from 30-40% to 80-90% in recent weeks. I wonder why? Is it because some changes in the way I am collecting the data or are those real changes? Is it real change? I also just noticed some negative numbers in the No VCS (%) column. That's not good. I guess I have to investigate this. Maybe during one of the Perl code reading and open source contribution events. Enjoy your week!

RECAP - The Weekly Challenge - 355 by Mohammad Sajid Anwar ( MANWAR ) Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Thousand Separator" and "Mountain Array" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. Mountain Separator by Arne Sommer The post demonstrates an idiomatic and compact use of Raku for typical programming challenges. It balances expressive language features with clarity, though readers unfamiliar with hyperoperators and the pipeline style might need supplemental explanation. Perl Weekly Challenge: Week 355 by Jaldhar H. Vyas Technically solid, readable, and well-structured. The solutions are both correct and practical, illustrating good problem decomposition and Perl/Raku coding style. Separated Mountains by Jorg Sommrey Efficient and idiomatic Perl for the thousand separator using a classic unpack pattern.️ A formally defined mountain array solution with vectorised and language-diverse implementations. number formatting and sorting by Luca Ferrari This is a well‑engineered, comprehensive, and professionally presented technical write‑up that goes beyond minimal solutions to showcase how to solve the Weekly Challenge across ecosystems. It favors clarity and breadth over micro‑optimizations, making it valuable for learners and polyglot developers alike. Perl Weekly Challenge 355 by W Luis Mochan The solutions for Weekly Challenge #355 are technically strong, correct, and efficient. Task 2 (Mountain Array) leverages PDL for vectorized comparisons, producing a concise, single-pass check for mountain arrays while correctly handling edge cases such as plateaus and short arrays. Thousand Mountains by Matthias Muth This is technically excellent, showing a high level of Perl proficiency, algorithmic awareness, and performance consciousness. Both tasks are solved correctly, with multiple alternative implementations explored and benchmarked, demonstrating a thoughtful and professional approach rather than a "just pass the tests" mentality. Oh to live on Array Mountain… by Packy Anderson ( PACKY ) This post is a strong, well-executed multi-language technical write-up that emphasizes algorithmic reasoning, clarity of transformation, and comparative programming paradigms over minimalism or raw performance. Thousands of mountains by Peter Campbell Smith This submission demonstrates strong problem understanding, solid algorithmic choices, and pragmatic Perl coding. The solutions are intentionally explicit, readable, and correct, favoring clarity and single-pass logic over clever one-liners. Both tasks are handled with approaches that scale reasonably and align well with Perl’s strengths. The Weekly Challenge #355 by Robbie Hatley This submission is technically strong, correct, and deliberately written for clarity and maintainability rather than brevity. It reflects an experienced Perl programmer who values explicit logic, readable structure, and thorough documentation. Mountains by the Thousand by Roger Bell West ( FIREDRAKE ) This is a thoughtful, well-structured solution to both Weekly Challenge tasks, with a clear emphasis on explicit logic and state-based reasoning rather than relying on library tricks. Roger demonstrates good cross-language fluency and a solid grasp of algorithm design. Commify every mountain by Simon Green ( SGREEN ) This post delivers clean, pragmatic, and idiomatic solutions to both tasks in The Weekly Challenge #355. It emphasizes using the right tool for the job, clarity, and efficiency over algorithmic novelty.

Full Salesforce Privacy Statement Effective as of August 26, 2025. At Salesforce, trust is our #1 value. This Privacy Statement describes how Salesforce collects, uses, shares or otherwise processes information relating to individuals (“Personal Data”) and the rights associated with that processing. 1. Responsible Salesforce entity Salesforce, Inc. and/or its affiliated entities (“Salesforce, “we”, “us”, or the “Company”) are responsible for the processing of your Personal Data as described in this Privacy Statement, unless specified otherwise, and act as the controller of such Personal Data. A list of Salesforce’s affiliates can be found in the List of Subsidiaries section of Salesforce’s most recent Form 10-K, available under the SEC Filings tab by selecting the “Annual Filings” filter on the page located here . This Privacy Statement does not apply to the extent we process Personal Data as a processor or service provider on behalf of our customers, including where we offer to our customers various services through which our customers (or their affiliates): (i) create their own websites and applications running on our platforms; (ii) sell or offer their own products and services; (iii) send electronic communications to others; or (iv) otherwise collect, use, share or process Personal Data via our services. For detailed privacy information related to a Salesforce customer or a customer affiliate who uses Salesforce services as the controller, please contact our customer directly. We are not responsible for the privacy or data security practices of our customers, which may differ from those explained in this Privacy Statement. For more information, please also see Section 10.3 below. 2. When this Privacy Statement applies This Privacy Statement applies to the processing of Personal Data collected by us when you: • Visit or interact with our websites that display or link to this Privacy Statement; • Visit or interact with our branded social media pages; • Visit our offices or other premises; • Receive communications from us or otherwise communicate with us, including but not limited to emails, phone calls, texts or faxes; • Use our services where we act as a controller of your Personal Data; • Register for, attend or take part in our events, webinars, programs, trainings, certifications or contests; • Act as or work for a service provider or supplier to Salesforce, to the extent Salesforce acts as a controller with respect to your Personal Data; • Are employed by a customer using our services where your Personal Data has been shared with us in our capacity as a controller (for example, during the sales or contracting process); • Participate in a Salesforce community, such as that focused on open source development; or • Participate in surveys, research or other similar data collection facilitated by us. We also host several online marketplaces such as: • AppExchange, which is an online marketplace for on-demand web applications that run on the Salesforce platform and that may be provided by us or by third parties (see https://appexchange.salesforce.com/ ), and • Tableau’s Extension Gallery ( https://extensiongallery.tableau.com ) which offers connectors and solutions that provide additional functionality for Tableau, such as dashboard extensions. When applications, connectors, extensions or other solutions are provided by us and they link to this Privacy Statement, this Privacy Statement applies. When these offerings are provided by third parties, the privacy statement of the relevant third party applies and this Privacy Statement does not. Our websites and services may contain links to other websites, applications, platforms and services maintained by third parties. Salesforce does not control these and the information practices of those third parties, including the social media platforms that host our branded social media pages, are governed by their own privacy statements. It is recommended that you read the applicable privacy statements carefully to understand their privacy practices. In some circumstances, we also collect, or our partners provide us with, publicly available information which may contain Personal Data that you have published or that has been made available online. The way in which our partners collect this is detailed in their own privacy statements, available on their websites. Salesforce may use artificial intelligence to process your Personal Data, including to develop and deploy AI systems. Where artificial intelligence is leveraged, it will only be used where legally permissible, in compliance with this Privacy Statement, and in a manner which is consistent with our commitments and values. More information on Salesforce’s responsible AI practices can be found here. For the avoidance of doubt, this applies where Salesforce processes your Personal Data as a controller. It does not apply to Personal Data you voluntarily submit to our services as an authorised user of a Salesforce customer for which Salesforce always acts as a processor. 3.

Parenting is the most rewarding, challenging, and unpredictable journey of a lifetime. Whether you're celebrating a first smile, navigating the tumultuous teens, or learning to let go with adult children, we're here for you. Parenting is a warm and supportive community built by parents, for parents. We're here to share the unfiltered realities—the sleepless nights and the belly laughs, the tough questions and the proudest moments. You are not alone on this adventure. Our Mission Our purpose is simple: to create a judgment-free space where parents can connect, share experiences, and find solidarity. We embrace the idea that there is no one-size-fits-all manual for raising children. Instead, we learn from each other, offering diverse perspectives and unwavering support through every stage of parenthood, from the first cries of infancy to the complexities of having grown-up kids. What to Discuss We encourage open and honest conversations about all aspects of family life. Jump into discussions or start your own on topics like: Milestone Moments: Share the joy of first steps, graduations, and everything in between. Tough Questions: From sleep training and toddler tantrums to screen time debates and difficult conversations. Product & Resource Swaps: Ask for recommendations on everything from the best strollers to books on navigating teenage anxiety. Personal Stories: Share the funny, messy, and beautiful moments that make up your unique parenting story. Seeking Advice: Get real-world perspectives on challenges you're facing. Relationship Dynamics: Discuss co-parenting, managing family expectations, and finding time for your partner. How to Get Involved Becoming part of our community is easy! Here’s how you can contribute: Ask a question: No question is too big or too small. The collective wisdom here is one of our greatest assets. Share your experience: Your story could be exactly what another parent needs to hear today. Offer support: Sometimes, the best response is a simple, "I've been there too." Lend an ear and a virtual shoulder to lean on. Leave some love: Engage with posts that resonate with you. Your participation helps great conversations rise to the top. Our Community Values To keep this a safe, welcoming, and helpful space for everyone, we ask all members to follow a few simple guidelines: Be Kind and Respectful. We all have different backgrounds and parenting styles. Engage in constructive, not critical, conversations. It's okay to disagree with an idea, but it's never okay to attack a person. Support, Don't Judge. This is a shame-free zone. Offer empathy and encouragement. We are here to lift each other up. Protect Privacy. Be mindful of sharing personally identifiable information about yourself and your children. What you share is public. Never share private information about other members. This Is Not a Substitute for Professional Advice. While sharing personal experiences is valuable, please remember that this community cannot provide professional medical, legal, or mental health advice.

Perl Weekly Issue #755 - 2026-01-12 - Does TIOBE help Perl? Perl Weekly Issue #755 - 2026-01-12 - Does TIOBE help Perl? latest | archive | edited by Gabor Szabo This edition was made possible by the supporters of our cause . Don't miss the next issue! Enter your e-mail: --> --> Hi there! Dave Cross has an article showing position of Perl on the TIOBE index. As I don't see any up-tick in new subscribers to the Perl Weekly nor do I see any increase in the MetaCPAN activity I keep track of, I doubt that the changes in the position reflects actual changes in the market. However I wonder, could the TIOBE index have an impact on the interest in Perl? How and when could we see that? Speaking of the MetaCPAN report , I'd love if someone sent a PR to the Perl Weekly that would generates same graphs using these numbers. Here is the issue for it. And another comment related to those stats. I just noticed that the No CI column went up from 30-40% to 80-90% in recent weeks. I wonder why? Is it because some changes in the way I am collecting the data or are those real changes? Is it real change? I also just noticed some negative numbers in the No VCS (%) column. That's not good. I guess I have to investigate this. Maybe during one of the Perl code reading and open source contribution events. Enjoy your week!

If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ . RECAP - The Weekly Challenge - 355 by Mohammad Sajid Anwar ( MANWAR ) Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Thousand Separator" and "Mountain Array" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. Mountain Separator by Arne Sommer The post demonstrates an idiomatic and compact use of Raku for typical programming challenges. It balances expressive language features with clarity, though readers unfamiliar with hyperoperators and the pipeline style might need supplemental explanation. Perl Weekly Challenge: Week 355 by Jaldhar H. Vyas Technically solid, readable, and well-structured. The solutions are both correct and practical, illustrating good problem decomposition and Perl/Raku coding style. Separated Mountains by Jorg Sommrey Efficient and idiomatic Perl for the thousand separator using a classic unpack pattern.️ A formally defined mountain array solution with vectorised and language-diverse implementations. number formatting and sorting by Luca Ferrari This is a well‑engineered, comprehensive, and professionally presented technical write‑up that goes beyond minimal solutions to showcase how to solve the Weekly Challenge across ecosystems. It favors clarity and breadth over micro‑optimizations, making it valuable for learners and polyglot developers alike. Perl Weekly Challenge 355 by W Luis Mochan The solutions for Weekly Challenge #355 are technically strong, correct, and efficient. Task 2 (Mountain Array) leverages PDL for vectorized comparisons, producing a concise, single-pass check for mountain arrays while correctly handling edge cases such as plateaus and short arrays. Thousand Mountains by Matthias Muth This is technically excellent, showing a high level of Perl proficiency, algorithmic awareness, and performance consciousness. Both tasks are solved correctly, with multiple alternative implementations explored and benchmarked, demonstrating a thoughtful and professional approach rather than a "just pass the tests" mentality. Oh to live on Array Mountain… by Packy Anderson ( PACKY ) This post is a strong, well-executed multi-language technical write-up that emphasizes algorithmic reasoning, clarity of transformation, and comparative programming paradigms over minimalism or raw performance. Thousands of mountains by Peter Campbell Smith This submission demonstrates strong problem understanding, solid algorithmic choices, and pragmatic Perl coding. The solutions are intentionally explicit, readable, and correct, favoring clarity and single-pass logic over clever one-liners. Both tasks are handled with approaches that scale reasonably and align well with Perl’s strengths. The Weekly Challenge #355 by Robbie Hatley This submission is technically strong, correct, and deliberately written for clarity and maintainability rather than brevity. It reflects an experienced Perl programmer who values explicit logic, readable structure, and thorough documentation. Mountains by the Thousand by Roger Bell West ( FIREDRAKE ) This is a thoughtful, well-structured solution to both Weekly Challenge tasks, with a clear emphasis on explicit logic and state-based reasoning rather than relying on library tricks. Roger demonstrates good cross-language fluency and a solid grasp of algorithm design. Commify every mountain by Simon Green ( SGREEN ) This post delivers clean, pragmatic, and idiomatic solutions to both tasks in The Weekly Challenge #355. It emphasizes using the right tool for the job, clarity, and efficiency over algorithmic novelty.

Install and set up Git and other dependencies (see the Git Setup page for detailed information). Fork the CPython repository to your GitHub account and get the source code using: git clone https://github.com/<your_username>/cpython cd cpython Build Python: Unix ./configure --with-pydebug && make -j $( nproc ) macOS ./configure --with-pydebug && make -j8 Windows PCbuild\build.bat -e -d See also more detailed instructions , how to install and build dependencies , and the platform-specific pages for Unix , macOS , and Windows . Run the tests : Unix ./python -m test -j3 macOS ./python.exe -m test -j8 Note: Most macOS systems use ./python.exe in order to avoid filename conflicts with the Python directory. Windows .\python.bat -m test -j3 Create a new branch where your work for the issue will go, for example: git checkout -b fix-issue-12345 main If an issue does not already exist, please create it . Trivial issues (for example, typo fixes) do not require any issue to be created. Once you fixed the issue, run the tests, and the patchcheck: Unix make patchcheck macOS make patchcheck Windows .\python.bat Tools\patchcheck\patchcheck.py If everything is ok, commit. Push the branch on your fork on GitHub and create a pull request . Include the issue number using gh-NNNN in the pull request description. For example: gh-12345: Fix some bug in spam module Add a News entry into the Misc/NEWS.d directory as individual file. The news entry can be created by using blurb-it , or the blurb tool and its blurb add command. Please read more about blurb in its repository . Note First time contributors will need to sign the Contributor Licensing Agreement (CLA) as described in the Licensing section of this guide. Quick links ¶ Here are some links that you probably will reference frequently while contributing to Python: Issue tracker Buildbot status Where to get help PEPs (Python Enhancement Proposals) Git bootcamp and cheat sheet Contributing ¶ We encourage everyone to contribute to Python and that’s why we have put up this developer’s guide. If you still have questions after reviewing the material in this guide, then the Core Python Mentorship group is available to help guide new contributors through the process. A number of individuals from the Python community have contributed to a series of excellent guides at Open Source Guides . Core developers and contributors alike will find the following guides useful: How to Contribute to Open Source Building Welcoming Communities Guide for contributing to Python: Contributors Documentarians Triagers Core team Setup and building Helping with documentation Issue tracker Responsibilities Where to get help Getting started Triaging an issue Team log Lifecycle of a pull request Style guide Helping triage issues Accepting pull requests Running and writing tests reStructuredText primer Experts index Development cycle Fixing “easy” issues (and beyond) Translating GitHub labels Motivations and affiliations Following Python’s development Helping with the Developer’s Guide GitHub issues for BPO users Experts index Git bootcamp and cheat sheet Triage Team Development cycle We recommend that the documents in this guide be read as needed. You can stop where you feel comfortable and begin contributing immediately without reading and understanding these documents all at once. If you do choose to skip around within the documentation, be aware that it is written assuming preceding documentation has been read so you may find it necessary to backtrack to fill in missing concepts and terminology. Proposing changes to Python itself ¶ Improving Python’s code, documentation and tests are ongoing tasks that are never going to be “finished”, as Python operates as part of an ever-evolving system of technology. An even more challenging ongoing task than these necessary maintenance activities is finding ways to make Python, in the form of the standard library and the language definition, an even better tool in a developer’s toolkit. While these kinds of change are much rarer than those described above, they do happen and that process is also described as part of this guide: Adding to the stdlib Changing Python Other interpreter implementations ¶ This guide is specifically for contributing to the Python reference interpreter, also known as CPython (while most of the standard library is written in Python, the interpreter core is written in C and integrates most easily with the C and C++ ecosystems). There are other Python implementations, each with a different focus. Like CPython, they always have more things they would like to do than they have developers to work on them. Some major examples that may be of interest are: PyPy : A Python interpreter focused on high speed (JIT-compiled) operation on major platforms. GraalPy : A Python interpreter which has first-class support for embedding in Java, built on GraalVM. Jython : A Python interpreter focused on good integration with the Java Virtual Machine (JVM) environment. IronPython : A Python interpreter focused on good integration with the Common Language Runtime (CLR) provided by .NET and Mono. Stackless : A Python interpreter focused on providing lightweight microthreads while remaining largely compatible with CPython specific extension modules. MicroPython : A tiny Python interpreter with small subset of the Python standard library that is optimised to run on microcontrollers and in constrained environments. CircuitPython : A fork of MicroPython designed to simplify experimenting and learning to code on low-cost microcontroller boards.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services.

Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services.

For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS Refer-a-Friend and Similar Incentive Programs . As described above in the How We Use Your Personal Information section ("Share Content with Friends or Colleagues" subsection), we may offer referral programs or other incentivized data collection programs. For example, we may offer incentives to you such as discounts or promotional items or credit in connection with these programs, wherein you provide your personal information in exchange for a reward, or provide personal information regarding your friends or colleagues (such as their email address) and receive rewards when they sign up to use our Services. (The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services. Said value will be reflected in the incentive offered in connection with each program. Accessibility . This Privacy Policy uses industry-standard technologies and was developed in line with the World Wide Web Consortium's Web Content Accessibility Guidelines, version 2.1* . * If you wish to print this policy, please do so from your web browser or by saving the page as a PDF.

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible. Terms and conditions for accessing or otherwise using Python ¶ Python software and documentation are licensed under the Python Software Foundation License Version 2. Starting with Python 3.8.6, examples, recipes, and other code in the documentation are dual licensed under the PSF License Version 2 and the Zero-Clause BSD license . Some software incorporated into Python is under different licenses. The licenses are listed with code falling under that license.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3. HOW WE USE YOUR INFORMATION We use your information for a variety of business purposes, including to provide our Services, for administrative purposes, and to market our products and Services, as described below. A. Provide Our Services We use your information to fulfill our contract with you and provide you with our Services, such as: Managing your information and accounts; Providing access to certain areas, functionalities, and features of our Services; Answering requests for customer or technical support; Communicating with you about your account, activities on our Services, and policy changes; Processing your financial information and other payment methods for products or Services purchased; Processing applications if you apply for a job we post on our Services; and Allowing you to register for events.

We may use personal information for other purposes that are clearly disclosed to you at the time you provide personal information or with your consent. Automated Decision Making. We may engage in automated decision making, including profiling, such as to suggest topics or other Users for you to follow. DEV's processing of your personal information will not result in a decision based solely on automated processing that significantly affects you unless such a decision is necessary as part of a contract we have with you, we have your consent, or we are permitted by law to engage in such automated decision making. If you have questions about our automated decision making, you may contact us as set forth in the "Contact Us" section below. De-identified and Aggregated Information . We may use personal information and other information about you to create de-identified and/or aggregated information, such as de-identified demographic information, information about the device from which you access our Services, or other analyses we create. For example, we may collect system-wide information to ensure availability of the platform, or measure aggregate data trends to analyze and optimize our Services. Share Content with Friends or Colleagues. Our Services may offer various tools and functionalities. For example, we may allow you to provide information about your friends through our referral services. Our referral services may allow you to forward or share certain content with a friend or colleague, such as an email inviting your friend to use our Services. Please only share with us contact information of people with whom you have a relationship (e.g., relative, friend neighbor, or co-worker). 4.

A. Disclosures to Provide our Services The categories of third parties with whom we may share your information are described below. Service Providers . We may share your personal information with our third-party service providers who use that information to help us provide our Services.

YOUR PRIVACY CHOICES AND RIGHTS Your Privacy Choices . The privacy choices you may have about your personal information are determined by applicable law and are described below. Email Communications . If you receive an unwanted email from us, you can use the unsubscribe link found at the bottom of the email to opt out of receiving future emails. Note that you will continue to receive transaction-related emails regarding products or Services you have requested. We may also send you certain non-promotional communications regarding us and our Services, and you will not be able to opt out of those communications (e.g., communications regarding our Services or updates to our Terms or this Privacy Policy). Mobile Devices . We may send you push notifications through our mobile application. You may opt out from receiving these push notifications by changing the settings on your mobile device. "Do Not Track." Do Not Track (" DNT ") is a privacy preference that users can set in certain web browsers.

You may stop or restrict the placement of Technologies on your device or remove them by adjusting your preferences as your browser or device permits. However, if you adjust your preferences, our Services may not work properly. Please note that cookie-based opt-outs are not effective on mobile applications.

In accordance with applicable law, you may have the right to: Access Personal Information about you, including: (i) confirming whether we are processing your personal information; (ii) obtaining access to or a copy of your personal information; Request Correction of your personal information where it is inaccurate, incomplete or outdated.

INTERNATIONAL DATA TRANSFERS All information processed by us may be transferred, processed, and stored anywhere in the world, including, but not limited to, the United States or other countries, which may have data protection laws that are different from the laws where you live. We always strive to safeguard your information consistent with the requirements of applicable laws. 7. RETENTION OF PERSONAL INFORMATION We store the personal information we collect as described in this Privacy Policy for as long as you use our Services or as necessary: to fulfill the purpose or purposes for which it was collected, to provide our Services, to resolve disputes, to establish legal defenses, to conduct audits, to pursue legitimate business purposes, to enforce our agreements, and to comply with applicable laws.  8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS Refer-a-Friend and Similar Incentive Programs . As described above in the How We Use Your Personal Information section ("Share Content with Friends or Colleagues" subsection), we may offer referral programs or other incentivized data collection programs. For example, we may offer incentives to you such as discounts or promotional items or credit in connection with these programs, wherein you provide your personal information in exchange for a reward, or provide personal information regarding your friends or colleagues (such as their email address) and receive rewards when they sign up to use our Services. (The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services. Said value will be reflected in the incentive offered in connection with each program. Accessibility . This Privacy Policy uses industry-standard technologies and was developed in line with the World Wide Web Consortium's Web Content Accessibility Guidelines, version 2.1* . * If you wish to print this policy, please do so from your web browser or by saving the page as a PDF. California Shine the Light . The California "Shine the Light" law permits users who are California residents to request and obtain from us once a year, free of charge, a list of the third parties to whom we have disclosed their personal information (if any) for their direct marketing purposes in the prior calendar year, as well as the type of personal information disclosed to those parties. Right for Minors to Remove Posted Content . Where required by law, California residents under the age of 18 may request to have their posted content or information removed from the publicly-viewable portions of the Services by contacting us directly as set forth in the "Contact Us" section below or by logging into their account and removing the content or information using our self-service tools. 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS If you are a resident of Nevada, you have the right to opt-out of the sale of certain Personal Information to third parties who intend to license or sell that Personal Information. You can exercise this right by contacting us as set forth in the "Contact Us\" section below with the subject line "Nevada Do Not Sell Request" and providing us with your name and the email address associated with your account. Please note that we do not currently sell your Personal Information as sales are defined in Nevada Revised Statutes Chapter 603A. If you have any questions, please contact us as set forth below. 10. CHILDREN'S INFORMATION The Services are not directed to children under 13 (or other age as required by local law), and we do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has uploaded personal information to our site without your consent, you may contact us as described in the "Contact Us" section below. If we become aware that a child has provided us with personal information in violation of applicable law, we will delete any personal information we have collected, unless we have a legal obligation to keep it, and terminate the child's account if applicable. 11. OTHER PROVISIONS Third-Party Websites or Applications . The Services may contain links to other websites or applications, and other websites or applications may reference or link to our Services. These third-party services are not controlled by us. We encourage our users to read the privacy policies of each website and application with which they interact. We do not endorse, screen or approve, and are not responsible for, the privacy practices or content of such other websites or applications. Providing personal information to third-party websites or applications is at your own risk. Changes to Our Privacy Policy . We may revise this Privacy Policy from time to time in our sole discretion.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

(The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services.

You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent.

This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics .

Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible. Terms and conditions for accessing or otherwise using Python ¶ Python software and documentation are licensed under the Python Software Foundation License Version 2. Starting with Python 3.8.6, examples, recipes, and other code in the documentation are dual licensed under the PSF License Version 2 and the Zero-Clause BSD license . Some software incorporated into Python is under different licenses. The licenses are listed with code falling under that license. See Licenses and Acknowledgements for Incorporated Software for an incomplete list of these licenses. PYTHON SOFTWARE FOUNDATION LICENSE VERSION 2 ¶ 1.

A no-nonsense (well, some-nonsense) podcast about API design & development, new features in the world of HTTP, service-orientated architecture, microservices, and probably bikes. Matt Trask: Cool. Welcome back to APS. You won't hate episode 17. I have Phil with me and we're joined by a very special guest today. Matthew Reinbold, fresh from postman, who is a director of API ecosystems and digital transformations here to talk about their report, the 2021 state of the API ecosystem. Matthew, how's it going? Matthew Reinbold: It is going. I am happy to be here first time, caller, long time listener. Is that how we say that? Matt Trask: I think that's yeah. It's how you say it. Yeah. So I mean, for those of you, like in the off chance that someone doesn't know who you are in the API ecosystem world can you give us a little bit kind of about yourself? Like you manage two different newsletters, at least as well as a pretty prolific Twitter presence as well. But if someone hasn't run into you, like. Matthew Reinbold: Well, yeah, well, first off, thanks for calling it prolific. Some people would call it annoying, but yeah, I I manage a fair number of tweets over at Twitter slash L I B E L underscore Vox, reliable Vox. That's where I talk about digital transformation and APIs and a lot of technology stuff. Occasionally. Fights with blockchain and NFT enthusiastic. But then I also manage, I also manage a newsletter called net API notes, where for almost 200 issues, going back to 2015, I've covered the landscape. I've shared essential bits of information. I've tried to boil down the, the. Current climate and get it right into just the most essential things that decision makers need to know and care about. And then I do a fair amount of blogging on a blog. That's very imaginatively named Matthew reinbold.com. In there, I talk about a fair number of things as well, but in, in, in short my passion is really about coaching people, helping people, teaching people to get better with their API ecosystem. Matt Trask: That's really cool. So one thing that kinda stuck out to me cause it's, so we're going to be talking about the 20, 21 Sidi APR report. However, I'm curious since you've been doing it now since 2015, you've been keeping notes on. The API world. How does your kind of, I hate to say this phrase, the 30,000 foot view of everything that, you know, from 2015, how does that kind of line up to what you saw with the 2021 state of the API report? Matthew Reinbold: Oh, that's interesting. So there's definitely. Maturing as a industry, we've gone through a number of phases. Those of us that have been around the block a few times, see trends come. And most often they, they tend to roll away. And over that time we have to develop models so that we can kind of. Pick the, the, the wheat from the chaff, you know, what, what are the properties of something new, some kind of buzzword, some kind of hyperbole that we can latch onto and say, yes, this is worth investing in. This is worth our interest in our effort versus, yeah, this is some marketing system, some spin as I'm looking at the 20, 21 postman report. I see. Where we've come. It's gone from being single point to point integrations. One-off bespoke API APIs to where we're now talking about things as ecosystems. We're now talking about collections of these things and how entire organizations. Manage these as, as something that's beneficial, something that's collaborative and, and managed as a separate entity rather than, than each individual unit I've got Phil here. So I have to use the forest for the trees analogy rather than just managing the individual API trees. There's now a greater awareness of what the forest, what the forest role is in the company and how to manage that. In a unique way, as opposed to the individual pieces. I will say for those that are listening, like I'm one of the things I want to highlight right up front here is that you don't have to enter an email address. It's not behind the page. We really felt strongly at postman that we had to get this information out to the most number of decision-makers so that they could make better decisions so that they could be informed as they're developing their strategies and roadmaps. So if you go to postman.com/state-of-api, you'll be able to download. With out any worry about having somebody from sales follow up with you later, or getting spam in your inbox, it's free for all. We want this information to be used. We want the dialogues to happen. We want the discourse to be rich and for me and frothy. And so please, you know, don't let past marketing spam. Stop you from checking this out. We want this in the hands of people. Phil Sturgeon: Fantastic. That's good to hear. I mean, that's I haven't got around to reading it as you might have seen from Twitter. Life has been a bit of a mess recently just spending far too much time in the field, as opposed to in the field doing APA stuff. But, yeah, that's definitely always been a concern of mine, of, you know, you hear about these white papers and reports and you just know so many of them like should have just be in the blog post, but instead that like a PDF that and you've got to enter information and then you just get like that fifth email, like, why didn't you reply to my previous four? I was like, I don't know who you are. I just want to read this thing. So yeah, I'm glad you folks are going in a different direction, but Maybe just taking a step back. Like, what is the state of API is report all about where are you getting your information from? What sort of research is being done? And what's the hospital. Matthew Reinbold: Great question. So this is, as far as I know, the largest survey of its kind, we had more than 28,000 people respond to our latest in a series. What we tend to do is try and track where the industry is at. And typically that's been around certain areas. Like how much time do you spend developing API APIs? What kind of tools are you using? Really good stuff there tracking the growth of, of the industry and the maturation of the industry. What I brought to the table this year. Was an interest on finding the behaviors that lead to sustainable, healthy API ecosystems. Like so much of what we talk about when it comes to API ecosystems is still very anecdotal. We tell stories about the Bezos Amazon memo, where we talk about like Twilio or Stripe, but when it comes to decision makers in large organizations, they're still. Trying to pull at what are decent KPIs, what are the behaviors I should be grooming or promoting within my company to make sure that I can keep producing quality API experiences again and again and again. And so what we did with this report that I'm really proud of is dig deep and discover, like, what are the correlating behaviors in organizations that lead to good things happening for companies? Phil Sturgeon: Okay. That's interesting. Cause I think. There's always this question around, like, what's a good API and what's a bad API. Right. And that's just such a nebulous, almost pointless topic so often, because you're just going to end up with opinions about camel case versus kebab case and opinions about rest versus graph UI, and all the nonsense that we love to fight about. And there's going to be someone with a fever at HTTP status code. And none of that actually matters, but you're talking about more of the business level stuff or what, what sort of things have come up as like. Really interesting results from, from your survey about how to build a good API what's what's, what's new and what's interesting. Matthew Reinbold: Right. Well, one of the things I wanted to look at was some of the insights that popped out to me when I was reading accelerate. So accelerate is like from. The previous decade, but it was written by Nicole Forsgren, Jess humble, Jean Kim, they came together and tried to figure out like, what was it about dev ops? That was so powerful. And they wanted to do it in a, in a way that quantified things, not just like, Hey, this is awesome. You should be doing it, but like get to the meat and potatoes of why is this powerful and why should businesses adopt dev ops? And as they went through their research they ended up discovering that there was really four things, four metrics that showed how dev. Made for better organizational performance. And those things were lead time, deployment, frequency, meantime to restore, or how quickly you recover and the change fail percentage. And I thought, huh, that's really interesting. Now that's for dev ops, but if these things are so instrumental in having organizations outperform. Their peers. Can we find the same correlation with API APIs? If we have the same behaviors, can we therefore then draw a line and say, if you have these things, if you have positive aspects of these four attributes, can you then have a more sustainable, more powerful API program? And based on our survey results, the answer is yes. So I can, I can go in and how we, how we drew that correlation. Phil Sturgeon: I'm curious, what sort of metrics are We, looking at? Matthew Reinbold: yeah. So first off we asked people on a 10 point scale. What, how, how well do you think that you've become API first? So out of our 28,000 respondents, they looked at this 10 point scale and they, they put themselves, you know, how they felt approximately 8% of the people that responded said, yes, we are either a nine or a 10 on the scale for API first, we said fine. And then we went through and we said, okay, you know, how long does it take you to make an API? Are we talking hours, days, weeks, so on and so forth. And we also said, okay, you know, not just time to produce, but how frequently you deploy and how many times do you have a deployment failure? Meaning like you put something in production, but it didn't work. Right. So you have to roll back and then like, what was your time to recovery? Like when an outage does occur and let's be. And outage always occurs at some point. Like how, how quickly can you recover from those things? So we got these nice, you know, bell curves and everybody kind of clumped toward the center on these things. And then we said, okay, Now the magic is we go back to that first question, the people that say their API first that have some kind of strong belief that they're doing API first, let's see how they compare to their peers on these metrics. And again, and again, all for these items, API, first people perform better. So, you know, taking one example here. API first people were able to deploy 17% faster than their peers and you know, in a day or less. So if you are API first and granted, there, there might be some subtlety in how a company defines that. But bottom line, if you are API first, you perform better on these metrics than your counterparts. Phil Sturgeon: Interesting. And yeah. Seeing, seeing as you raised it, what is API first? There's, there's a lot of different definitions floating around. Right. And so just for listeners that might not have listened to everything we've ever talked about and read every blog post we've ever read ref ever wrote how do you define it? Matthew Reinbold: Sure. Well, first for people that haven't heard this and haven't listened to every episode, shame on you. Second, I define I defined API first and. Making the API experience or the interface, the primary means for the functionality exchange. So not viewing, like I'm going to create this functionality and then subsequently go and some other team or, or some other project we'll be wrapping this thing in an API. It's thinking of creating an API experience as the primary exchange mechanism with dysfunctional. Not a library, not a module, not a class, the API. So this is slightly different than API design first, which is, I am going to subsequently talk to stakeholders, create a model, whether that's in an open API document or some other means, but I'm going to sketch that out. Test my assumptions, and then subsequently only begin code after. That's API design. First, I do draw a line between those two. They are very copacetic. They, they work together like peanut butter and chocolate, but there, there is a difference. You can, you can do API first without necessarily being API design first. Phil Sturgeon: For sure. Oh, well, we've got you on a roll. You're doing these really well. What is API as a product? Matthew Reinbold: Ooh, API API as a product. So that is creating an API with the. Awareness that it will have a roadmap. It will have ownership beyond just being put into a production environment that it will grow and change and subsequently necessitates the kind of modeling responsibilities and, and awareness that it will be growing and changing over time. Phil Sturgeon: Okay. So instead of, yeah, API first is your product should have an API. And that will be managed by the team who was making this product. And API as a product is a slight variant of API. First, that kind of takes that API out of that generic functionality team and says the API itself is the product. And another team potentially on the same team will be making a product using that Matthew Reinbold: Right. I, I would, I would, I would venture there's a lot of large enterprise environments for which API for. It's about a project that gets the thing into production. And then that thing is left to operate and run on its own. Perhaps there's some monitoring, perhaps some observability, but the actual team that made it is off doing the next thing and the next thing and the next thing there's not the idea that. This is a long lived item that, that produces some kind of business functionality value that is competing in a complex dynamic marketplace like that. That's the API product side of the house. Phil Sturgeon: Hm. Matt Trask: So the, I guess like the, the big question to bring up, I think right now is what did the pandemic do for the API ecosystem? Matthew Reinbold: Well, you know, first of all, I want to just stress that, that this thing that we kind of hand wave is the pandemic was actually like multiple congenital. Crises all at once. Right. You know, I, I want to, for the audience, like we're talking social unrest and political upheaval and supply chain disruption, and the, the pandemic was really a catch all for a tremendous amount of business stress. And what we've seen in the report is the usage of APIs, the number of API APIs the. Amount of focus and care on API. APIs has increased tremendously with that pandemic because business leaders, technology leaders are struggling with this amount of change, this amount of disruption. And so having architectures that are slow to change, difficult to change is just not cutting it in this. Set of multiple crises. So any kind of architectural advantage that allows them to change rapidly change quickly to do different things with how their development investment is deployed. So, you know, for example, taking that one dev team that was altogether in the office and being able to break it down into microservices to allow for greater asynchronous operation, greater flexibility. Those are the architectures that are being sought right now. Matt Trask: Yeah, that makes sense. I mean, it always here in America, I don't know if it feels sing, but you know, like there's. At the core level there. So like the whole, did we go back to the office and be Sandy the office upheaval as well. So it makes sense that there is kind of like a, a struggle on rapping, like getting non-technical CEOs, CTOs, CFOs their heads around the game-changing, this of APIs that doesn't surprise me at all to hear that they're still kind of, I don't want to say struggling, but unsure. Maybe like, Matthew Reinbold: Well, and, and, well, I, I think that's an interesting perspective because it assumes that leaders were in command and control positions of how the labor was divided anyway. And I would actually, I would actually posit that it's the opposite. It was everybody immediately going and running to their home offices and working in a remote work environment. The change in the communication paths changed the architectures that were subsequently produced by those teams. It's Conway's law in effect. And therefore, as we, as we look forward, as we look forward to what's going to happen, I would, I would venture that the organizations that pull people back to centralized locations, for whatever reason, I'm not going to debate whether that's good or bad, but the people that pull the development teams back to. see, like the Terminator two bad guy they'll reform remold because there will be more efficient communication patterns when everybody's face to face. Whereas those organizations that continue to have a distributed workforce will have more distributed architectural patterns because that's how communication is happening. Phil Sturgeon: That's really interesting. I haven't really thought about it before, but I, I, I bet there's been an uptick in kind of API design first, specifically due to this as well. Right? Because my experience working we work was, was pretty awful as far as like API planning goes and as a result, APA architecture and API performance and Matthew Reinbold: You don't say you should blog about that. Fail. Matt Trask: Yeah. Phil Sturgeon: 25. I'm going to do a book about that shit. Matt Trask: Have you tweeted about this yet? Phil? I'm not sure if anyone knows your true Phil Sturgeon: I did a talk. I did a talk recently. But yeah, there was, there was such an element of like, we're real in an open plan office, playing ping pong together and shooting each other with nerves that there was never any effort on API contract being written down in any shape or form because you're all sitting about. And you're just like, what's that end point? Cool mate. Oh, if slash whatever. Oh, is that a, is that property of booty? It's a string called true with QuoteWerks and then you didn't have a need to write it down because you just show it over, over the top of Nerf fire. And I, I do wonder if remote work, well, not necessarily remote work, but quarantine remote work has helped push people more towards it because if you can all be sitting around asking each other, you're going to be typing. The contract over slack. And if you're going to be typing it out over slack, which is inherently ephemeral, then you might as well type it into a Yammel file and commit that in the repo. And then you can have design reviews around the board request or other tools that the offer, that sort of thing. So, yeah, that's, that's just completely a hypothetical and something I'm thinking the second night and check that, but I'm sure it's happening. Matthew Reinbold: I completely agree. And, and let me throw in something that's not in the report, but something that's got me totally geeked out and I'm watching for on my radar, we are going to see the greatest Renaissance of API design documentation that we've ever seen in the next couple of years. Now, granted, you know, as far as Renaissance goes, maybe Renaissance. Documentation are not that great. So, you know, let's put the party hats back in the closet, but what we're seeing with the great resignation right now is all of that knowledge that people acquired in their heads is leaving. It's headed out the door and I've read reports like up to 80% of how to do things with API APIs is in people's heads. Like at we work. If you needed to know how API has worked. You know, you knew Phil was the guy that could get you straightened and Phil Sturgeon: I didn't have a clue. That was the problem. I was trying to find out how to do it. Matthew Reinbold: Okay. So I wasn't, it was somebody, it was somebody on the other end of a, of a Nerf battle away Phil Sturgeon: Someone who quit already is the person that you. Matthew Reinbold: But right now in organizations like you have this phenomenon where a tremendous number of people are leaving organizations and they might've been the sole person who knew where the end points were or knew how that particular tricky function worked. And as organizations are trying to deal with this and recover and still be productive, there's going to be a greater emphasis on having that crap written down, having things documented. Organizations don't have aren't left on their back foot like they are right now. So whether that's heavy handed processes, whether that's just a greater appreciation for documentation among the staff, that's left, whatever that manifests as there's going to be an increasing amount of emphasis on documentation, because people have seen that too much was stuck in people's heads and it's not sustained. Phil Sturgeon: Yeah, that's a really good point. I mean, and not just kind of documentation, but the whole open API as a source of truth earlier on. And I figured it has to be, has to become more noticeably important when Yeah. They've, they've lost the whole team. How the API works and you know what it's like, code's always a bloody mess. Cause you just hacked up within about what over the place and patch things and fix things. And what about and yeah, when they find themselves rewrite in the API, cause no one can really take it over and no one remembers how it works and there's no documentation for it. And it's just too hard to figure out when they just make a brand new one. And they have a whole brand new team doing it. Cause they've already lost all that stuff. Matthew Reinbold: Yeah. Phil Sturgeon: That's a situation that a lot of managers and business people are going to say, how can we go about avoiding doing this? And I just hope there's someone in the room that says, well, APA designed first would really help avoid this problem because otherwise they'll just repeat all the same mistakes again. Matthew Reinbold: Right. Absolutely. Whether it's design first or tools that help analyze existing traffic and write the document afterwards, like whatever you got to do, get that written down and start taking some notes against it because. It's it, I believe right now with the great resignation. It's an Achilles heel. That's probably hampering a lot of organizational ecosystems right now. Matt Trask: Yeah, I would definitely agree. I mean, it shows in the report under open API three dot oh, 44% of people are aware of it, but they don't use it 28% say they use it. 12% said they use it, the love it. So even just combining use it and use it in love. It still does not match aware of we're not using it. Which means that there is definitely a. A river to jump over. So to speak, to getting more people on, to open API, which is probably currently like the standard for API documentation right now which comes back to your point, which allows them to start writing things down and start documenting things. And Phil gets it by bus tomorrow. We work is still going to be okay. It very well could happen. Which is exactly why I use that example. And it, it, yeah, it it'll give the organization a little bit more or a little less reliance on what's in people's heads a little bit more stability in case great races, nation three Datto happens in three years. You know, you don't know what's gonna happen. Phil Sturgeon: Is that when everyone resigns from web three point now, Matt Trask: please. Don't don't threaten me with a good time. Like I've already, I've already muted those web three and NFD on my Twitter and it cleaned it up so Phil Sturgeon: Why do you hate progress, man? Matt Trask: A lot of reasons. I'm a combustion at heart? No. Matthew Reinbold: Hey, if you don't, Phil Sturgeon: particular messages of this progress that are the problem. Matthew Reinbold: if you, don't stand for something, you'll fall for anything. Good for you, Matt. Matt Trask: yes, I've always wanted my life to be attributed to a, a Hamilton quote. So I am glad I did. I can check that one off to get back onto the actual topic and not just bashing NFTs for an hour and a half, which sounds like a lot of fun. What you the most about this report? Like what was something that you read that just you weren't expecting? Matthew Reinbold: I, I think there was two things that when you combine them together it made me tilt my head and go, huh? The, the first is that more than anything else? Including speed to production. People want quality API APIs. They want stability. They want some other things reliability. But the primary thing that people want out of their, their API APIs is quality. And yet when it came to whether or not people had time to test. Everybody acknowledged that testing was good. Tested was valid, but nobody had enough time for testing and it's like, huh? These two things kind of seem like. The, the two sides of a coin, right. You know, people aren't getting the quality that they want, but everybody acknowledges that they don't have enough time to do testing, even though they recognize the testing is an extremely valuable type thing. So I think when it comes to socializing this report and talking to decision-makers and doing the kind of coaching that I so often do, I, this is one of those things too, to bring up, like how in your program are you supporting. Testing and ensuring that enough is being done there so that your developers feel like you're, you're reaching the kind of quality goals that, that you're, you're promising to the rest of the world. Phil Sturgeon: Hm, do you, is the survey broken down by role? So can you, can you look to see if. Managers and engineers have a rule, very interested in, in high quality. And engineers are going, but we don't have enough time, but the manager's like, oh, they definitely have enough time. Matthew Reinbold: Right. So we do have a breakdown by role and job title, but I don't have the numbers in front of me that, that combined, and show me how to break down the quality question. Phil Sturgeon: Yeah, that'd be an interesting one. Cause yeah, so many roles, so many organizations, I just take it as like a universal truth is that companies are just, you know, business and product are demanding feature, feature, feature, feature, feature, and engineers are just like screaming, just keyboards on fire, trying to try to hit them goals. And everything's just wonky as hell. And it seems to be everywhere I go. There's not enough to have. There's not enough time for QA. They might've got rid of the QA team because it's slowed down product and slowed down delivery of features. Yeah, everyone wants high-quality API has, but no one wants to put the time in to testing because testing is inherently hard and slow. Matthew Reinbold: Right. And kind of along those same lines, another stat that jumped out at me was that 76% of the people building API APIs have less than five years experience doing. I mean, you know, as far as restful APIs now, we're, we're more than a decade into that journey. So that stat leaps out at me, like what is it about API development, where we're getting people with zero to five years experience like what's happening. There are the successful API builders, aging out and becoming management. it, are they moving on to web three O and NFTs? Like, like what is, where are our experienced API builders and why are these critical pieces of business infrastructure? In the hands of relatively younger people. That's not to say that they can't be doing a good job, that, that it's impossible to build a great web experience at your first time at bat. But it's also something where I think everybody on this call would probably agree. Experience counts, experience matters. Ha being around the block once or twice, you pick up a feel for what's beneficial, what's maybe a little wonky and you can imbue that into a better design at launch. So, you know, where are the. 10 year, the 12 year, the 15 year veterans. And why are they not the primary source of API infrastructure development? Phil Sturgeon: Yeah. Some that I've seen so much, again, just, I love complaining about we work. Pretty much everyone that was a junior developer, Right. Like the vast majority, what, what you need developers and their role responsible for creating you know, there's like a hundred API APIs and, you know more than a hundred junior developers with just a sprinkling of seniors who were more on the cowboy coder end of things. Not, not to be rude, you know, like startup, you need to be super agile, super fast, not, not a perfectionist. And so, so many of the problems where this is, this person's first rails app, like they know how to accept incoming Jason parameters and they know how to spit something back from the database. And. That's that, and they know how to make a web request. So he talks to . He talks to F talks to G in the thread, and then no, one's got a timer anyway. So everything falls over, like, things like that. The sort of thing you realize, if you've been doing APIs for five years, or for 10 years, you've been doing it for 10 years, you wouldn't do that. You just wouldn't do that. You'd put something in a sidekick job and then implement a web socket or a web hook, or literally anything else. But. That's the sort of thing you do when you consider like HTP failures or server downtime, to be an edge case that is like some weird scenario that probably won't happen. And when you've been doing it for a longer time, you're like you, you change your mindset to this web requests probably won't work. And on the off chance that it. This is what should happen. And you just get really defensive and paranoid and have like 25 different guard statements and, you know, 25 different types of ex exception catching and, and every single circuit breaker and trigger warning that you can possibly put on this thing. And there is, yeah, there is a change in mind. Around around that kind of it doesn't, I'm not being a gatekeeper or at least they're saying you've got to be doing EPS for 10 years until you're good. But when you start out, you you're such, you're more of an optimist. You haven't seen it go wrong in as many ways. You haven't had cascading failures and you haven't had all these terrifying things that happen. So that, that is definitely a concern for me is that I think, yeah. Happy, happy path development. When you go from having one AP. To having 20 or a hundred, the, the the chance of straying off the happy path gets exponentially worse. Right. And, and that's just something, I think a lot of these younger developers on experience with. Matthew Reinbold: Right. Even, even when it comes to design, having used API APIs, having to incorporate the API APIs, you better understand what makes a good description and what is just a reiteration of the, the name itself. Yeah. Yeah. If I have a field called date of birth and the description is just the birth, that, the date that the person was born on, like, well, what was the. do I need to refresh it? Or is it cashed? You know, like, can I store it or is it part of some kind of regulatory PII? And I shouldn't, you know, I can use it, but I shouldn't store, like, there's so many issues that once you've been down that road, and then you're asked to produce an API, you bring that experience with you and you put it into the description that adds so much that yeah. I, I, I, I don't know. How we continue to get that, that experience circulating and get that in front of people. But I think it's really important. Matt Trask: Well, I must wonder too, like how many of those, like experienced API builders are getting swallowed up into Stripe? Twilio, Google. And kind of almost locked away working on their API APIs and not able to share their experiences down the road to junior developers in their own companies or interim networks, things like that too, because it feels like you do your five, seven years as developer, you get pulled into the management game and then all of your knowledge is still there, but you're having to balance both managing a development team, hitting your goals. Pushing out products because you've got to make money for the business. And all of your knowledge that you've worked so hard to gain is kind of sidelined in the name of profits or KPIs or whatever it might be. Matthew Reinbold: Possibly there's, there's certainly exceptions that spring to mind. One of which is Tim Burks and the team over at Google and with the number of resources that they put out there. For their APIs. It's, it's kind of a mouthful, but if you do a Google search for that, they've produced a tremendous amount of documentation about how they support API APIs at scale, how they do their design reviews, how they think about consistency and cohesion across their entire footprint. So that certainly what you described could be the case in some places. You know, I, I, I do think that it's not necessarily the default that's people go off to these big organizations and then just disappear because the folks at Google around Tim and his crew they're doing some great work. Phil Sturgeon: So I've been sat in the room with you having these sort of conversations your last job, Right, Like a center of excellence type stuff. You, you get a bunch of smart people and me together and start talking about what, what would help with these various different problems? Like how do we do APA design reviews? How do we do governance? What standards should we be interested in? So I think sometimes yeah. Experienced developers can get sucked up into these companies and kind of finish and end up having that scale was used for something else. But I, I think companies that have those governance processes, like they're sharing their experience back by creating style guides, by creating programs that they explain how these, how these like API designed life cycles or API life cycle should work. And that's a way that they can essentially. Distribute their experience. So instead of like, I know what to look for when I'm reviewing a poor request, they can create a style guide. That means that everyone will do that. I think the danger there is that when style goes focus on what, instead of why then, then you kind of lose some of that experience because it just seems like arbitrary decisions delivered from upon high. Right. You just get. Do it this way, but, but Y I've read loads of style guides recently. And, and some of them, I should probably show the examples. It's just like, do this. Like, why you don't tell me what to do? You don't my dad, like, it just, I couldn't figure out what they possibly could have meant by it. Cause usually I can look at something. Why might they mean that? Oh, that reminds me of a thing that happened along these lines. They probably got burned by that before, and they want to avoid it, but if you don't see why it just sounds arbitrary and you're not actually teaching anyone on anything, but if you do it right. that that can be really helpful. Matthew Reinbold: Right. And it's also essential that if you're designing these systems like a governance or like a center of excellence that you have the feedback process that you have, the, the communication cycles so that when people do have that kind of. That they have a recourse. It's not a dead end. It's not either you do this or you're punished for it, but oh, if this doesn't make sense, here's who you talk to. Here's how you can escalate your concern here is how you elevate your edge case. And we can have a discussion about it and you can help co-evolve this thing, because you own this as much as somebody else, the, the phenomenon that you described, where it's a dead end. It's thrust upon you. You don't have ownership of that. And as a developer, that does not feel good, that does not invest you in seeing the long-term growth of, of that system. You want to burn that system. You want to be the rebels flying through the death star trench. You want to take that thing down? So what's essential is to realize. You provide the avenues for people to, to voice their concerns, voice their questions, and make them feel heard in such a way that their process, the process is theirs. It's not something done to them. It's it's their process. Phil Sturgeon: I'm just laughing about the death star rebel situation. Now I'm completely distracted. I need to go rewatch some star wars. I don't know. Matt Trask: I mean, your, your thought on the ownership thing is also interesting cause And we like watching the junior Twitter, the junior developer Twitter circles, which is not the end all be all of it all, but there is a large emphasis on if you want to make more money, you need to jump ship every two years on average. And that kind of removes the does or not the desire, but like the, the ownership of any sort of product from a junior developer, because in two years, they're going to be onto another thing. They're going to be onto another system. Codebase, maybe another language and it, it does kind of bring back, like, how do you entice people to have ownership, even if they only are going to plan to say somewhere for a short period? Because we all know that like having, like you said, having that ownership is going to kind of make you more invested, more caring, more thoughtful, more empathetic towards whatever it is that you're building. Matthew Reinbold: Right. I mean, we're veering into management territory, which I'm happy to talk about. I, I know. Matt Trask: very allergic to management. So. Matthew Reinbold: But I, I was just reading Harvard business review. Hey, I'm fun at parties too. So I was reading Harvard business review talking about COVID and the great resignation and the, the management challenges that, that come with that and what we need more. In all companies is a feeling of belonging, a feeling like we have a career progression feeling like our, our, our work has impact and all too often management, just as about making sure people don't do dumpster. Right. You know, I'm, I'm here to police you because the organization doesn't trust you. And it leads to all kinds of weird effects. Like, Hey, if you actually want to grow your career, you need to leave. You need to hop companies every two years and let's be clear that may work, but it's still very disruptive, not just for the company, but for the individual. 'cause they're having to rebuild all of those social structures, their relationships, their patterns, the routines it, it's not, it doesn't come for free. And so from a management standpoint, if you can show people how to have that fulfilling career, how to fulfill those needs. They don't have to jump ship every two years. There's no reason that that has to be the default blueprint. And from a company standpoint, you actually benefit from that accrued experience rather than having a developer. That's done the same thing. Five times you get five years of experience. That's really powerful, really tremendous. And that, that ultimately not only leads to better APIs, but leads to a better employee. So there is a disconnect we need to work with our management layers. It shouldn't just be the technician that has some headcount is by default manager. There needs to be an appreciation for how those are unique skill sets. Those are unique muscles that need to be exercised, but. If we can create that fulfilling sense of duty then, and that the career path for these individuals, we can get them off of this kind of binge and purge career treadmill. Matt Trask: So that's a really, yeah, that's a really good way to put the whole two year turn. And I mean, it comes back full circle to what you just said earlier, which is, you know, 75% of API has been developed now or done by people with less than five years experience. And that's probably because of the same, people are jumping, jumping, jumping. Whereas if you can keep them around, make them happy, make them feel like they belong. We might actually start seeing that number. Dropped significantly to more experienced API developers building more thoughtful API design with, with years of knowledge built up. So I think it'll be really interesting to see kind of what happens with this great resignation how that all shapes up. And then it'll be interesting to see to kind of the 2022 say the API report. How does that. How, how will things change from a year in a year going forward? And what can we expect possibly looking at these two years, the next five years after that, the next 10 years growing on different trends, you know, we might see NFTs ruling the world. We might see graph QL. Rolling. Phil Sturgeon: No comment. Matt Trask: Matthew is kind of shrugging Phil Sturgeon: we're all sad. Now, rural sat now, NFTs powered by graft UL, problem solved. Can you, can you still right click that? No, you can't. It's like a post. So. Matt Trask: Well, there goes Matthew Reinbold: Each unique query is published as an innovator. And you can put the ownership of that query in a blockchain so that you don't have the centralized point of failure. Phil Sturgeon: I was going to thank you for being for, for making this podcast sound intelligent for once. And, Matthew Reinbold: And then I ruined it. Sorry. Phil Sturgeon: and then you. Matt Trask: no, no, no, you didn't ruin it. You just brought it back down to its normal level of ridiculousness. Phil Sturgeon: Fantastic. No. Do you have any predictions for what we're going to see in the, in next year's state of this report? Because then we can play that clip back and laugh at how wrong you were. Matthew Reinbold: Oh, lovely. All right, well, let me have a few minutes to sandbag my answer. No, I think there's a tremendous amount of, of areas where we can take this correlation that I talked about before behaviors. You know how the question immediately becomes well, okay. If these four behaviors are so good and are present in high-performing API companies, how do we get there? And this year we had a little bit around leadership and what leaders do. To get an API first company. I think there is a lot of exploration we can do there to really dial in and say, okay, we know these things are good. How do you get there? How do you promote these things? How do you, how do you get it so that you are able to deploy in a minimal amount of time or recover faster? What are leaders in those organizations doing? That's one of the things I'd love to dig into obviously. A lot of post pandemic aftermath. There's been a tremendous amount of published about how this digital transformation and, you know, we're so much more flexible and adaptable because we, we are now doing all our conversations over zoom. And I look at that and I, I scratch my head because. Digital transformation, at least in the non buzzword compliant way is a whole lot more difficult than just moving everything to a slack conversation or a, or a zoom conversation. Like it means fundamentally dismantling your policies and procedures and reinventing them in a way that digital technology lends itself to. So figuring out what that post pandemic landscape looks like and how we're still feeling the knock on effect. Is going to be something that's also going to be very interesting to explore. Matt Trask: Yeah, that's definitely true. I mean, I think one thing I would like to see is, is that number of people who know open API, but don't use it start to gradually shift down and people who are using open. Start to shift up, which, you know, from a silver right back to having documentation and some sort of notes about their API. So when the, the knowledge people do eventually leave because everyone leaves the company at some point, the knowledge isn't necessarily leaving. And instead we're, we're kind of leaving a better legacy to the people following us. Yeah, definitely. Matthew Reinbold: Here here. Matt Trask: Cool. Matthew, thank you so much for taking some time out of your, your, your day to talk to us. We really appreciate it. Look forward to having you back in roughly a year's time to talk 20, 22. Say the API report Matthew Reinbold: I love it. Let's do it. Pencil it in right now. Matt Trask: Yep. It's it's on my calendar. I don't know what I'll be doing in a year from today, but I know for a fact we'll be talking again. If you want to get. Matthew on Twitter. He is at libel Vox, L I B E L underscore V O X M. And we'll throw the link to your blog and Twitter in the show notes as well as everything else. Awesome. Cool. Thank you so much. We appreciate it. Phil Sturgeon: Yeah.

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Navigation Node.js SDK Send and Track Events Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog Node.js SDK Send and Track Events OpenAI Open in ChatGPT Learn how to send events to trigger workflows, with code snippets and examples. OpenAI Open in ChatGPT ​ Send Event You can send event to Suprsend platform by using the supr_client.track_event method. When you call supr_client.track_event , the SDK internally makes an HTTP call to SuprSend Platform to register this request, and you’ll immediately receive a response indicating the acceptance status. The actual processing/execution of event happens asynchronously. Request Sample Response Copy Ask AI const { Suprsend , Event } = require ( "@suprsend/node-sdk" ); const supr_client = new Suprsend ( "_workspace_key_" , "_workspace_secret_" ); // dictionary containing variable/info about event, If none use {} const properties = { "key1" : "value1" , "key2" : "value2" } const event = new Event ( distinct_id , event_name , properties , { tenant_id : "_tenant_id" , idempotency_key = "__uniq_request_id__" }) // trigger request const response = supr_client . track_event ( event ) response . then (( res ) => console . log ( "response" , res )); Parameter Description distinct_id distinct_id of subscriber performing the event. event_name string identifier for the event like product_purchased . This should exactly match the one from created workflow. properties dictionary representing event information. This can be used to pass variables to template. Property keys shouldn’t start with ss_ or $ . tenant_id (Optional) Tenant ID of the tenant. idempotency_key (Optional) unique key in the request call for idempotent requests . Event naming guidelines: Event Name or Property Name should not start with or , as we have reserved these symbols for our internal events and property names. ​ Idempotent requests SuprSend supports idempotency to ensure that requests can be retried safely without duplicate processing. If Suprsend receives and processes a request with an idempotency_key , it will skip processing requests with same idempotency_key for next 24 hours. You can use this key to track webhooks related to workflow notifications. To make an idempotent request, pass idempotency_key in the event instance. idempotency_key should be unique that you generate for each request. You may use any string up to 255 characters in length as an idempotency key. Ensure that you don’t add any space in start and end of the key as it will be trimmed. Here are some common approaches for assigning idempotency keys: Generate a random UUID for each request. Construct the idempotency key by combining relevant information about the request . This can include parameters, identifiers, or specific contextual details that are meaningful within your application. e.g., you could concatenate the user ID, action, and timestamp to form an idempotency key like user147-new-comment-1687437670 Request-specific Identifier : If your request already contains a unique identifier, such as an order ID or a job ID, you can use that identifier directly as the idempotency key. ​ Trigger multiple events in bulk Use .append() on bulk_events instance to add however-many-records to call in bulk. Request Response Copy Ask AI const { Suprsend , Event } = require ( "@suprsend/node-sdk" ); const supr_client = new Suprsend ( "_workspace_key_" , "_workspace_secret_" ); // create bulk instance const bulk_ins = supr_client . bulk_events . new_instance (); // create event1 instance const event1 = new Event ( "distinct_id1" , "event_name1" , { "k1" : "v1" }) // create event2 instance const event2 = new Event ( "distinct_id2" , "event_name2" , { "k2" : "v2" }) // add event instance to bulk instance bulk_ins . append ( event1 ); bulk_ins . append ( event2 ); // OR bulk_ins . append ( event1 , event2 ); // trigger request const response = bulk_ins . trigger (); response . then (( res ) => console . log ( "response" , res )); ​ Add file attachment (for email) To add one or more attachments to a notification (viz. Email), call add_attachment() on event instance for each attachment file. Ensure that attachment url is valid and public, otherwise error will be raised. Since event API size can’t be > 100 KB, local file paths can’t be passed in event attachment. javascript Copy Ask AI const event = new Event ( distinct_id , event_name , properties ); event . add_attachment ( "/home/user/billing.pdf" ); event . add_attachment ( "https://www.adobe.com/sample_file.pdf" ); A single event instance size (including attachment) must not exceed 100KB (100 x 1024 bytes).

React Únete a la React Conf del 7 al 8 de Octubre. Más información. React v 19.1 Búsqueda ⌘ Ctrl K Aprende Referencia Comunidad Blog React La biblioteca para interfaces de usuario web y nativas Aprende React Referencia de la API Crea interfaces de usuario a partir de componentes React te permite construir interfaces de usuario a partir de piezas individuales llamadas componentes. Crea tus propios componentes de React como Thumbnail , LikeButton , y Video . Luego combínalos para formar pantallas, páginas y aplicaciones. Video.js function Video ( { video } ) { return ( < div > < Thumbnail video = { video } /> < a href = { video . url } > < h3 > { video . title } </ h3 > < p > { video . description } </ p > </ a > < LikeButton video = { video } /> </ div > ) ; } My video Video description Sin importar si trabajas por tu cuenta o con otros miles de desarrolladores, utilizar React se siente igual. Está diseñado para permitirte combinar a la perfección componentes escritos por personas, equipos y organizaciones de forma independiente. Escribe componentes con código y marcado Los componentes de React son funciones de JavaScript. ¿Quieres mostrar algún contenido condicionalmente? Utiliza una sentencia if . ¿Mostrar una lista? Prueba la función map() de un array. Aprender React es aprender a programar. VideoList.js function VideoList ( { videos , emptyHeading } ) { const count = videos . length ; let heading = emptyHeading ; if ( count > 0 ) { const noun = count > 1 ? 'Videos' : 'Video' ; heading = count + ' ' + noun ; } return ( < section > < h2 > { heading } </ h2 > { videos . map ( video => < Video key = { video . id } video = { video } /> ) } </ section > ) ; } 3 Videos First video Video description Second video Video description Third video Video description Esta sintaxis de marcado se llama JSX. Es una extensión de la sintaxis de JavaScript popularizada por React. Al poner marcado JSX cerca de la lógica de renderizado relacionada hace que los componentes de React sean fáciles de crear, mantener y eliminar. Añade interactividad dondequiera que la necesites Los componentes de React reciben datos y devuelven lo que debe aparecer en la pantalla. Puedes pasarles nuevos datos en respuesta a una interacción, como cuando el usuario escribe en un campo de texto. React actualizará entonces la pantalla para que se corresponda con los nuevos datos. SearchableVideoList.js import { useState } from 'react' ; function SearchableVideoList ( { videos } ) { const [ searchText , setSearchText ] = useState ( '' ) ; const foundVideos = filterVideos ( videos , searchText ) ; return ( < > < SearchInput value = { searchText } onChange = { newText => setSearchText ( newText ) } /> < VideoList videos = { foundVideos } emptyHeading = { `No matches for “ ${ searchText } ”` } /> </ > ) ; } example.com / videos.html React Videos A brief history of React Buscar 5 Videos React: The Documentary The origin story of React Rethinking Best Practices Pete Hunt (2013) Introducing React Native Tom Occhino (2015) Introducing React Hooks Sophie Alpert and Dan Abramov (2018) Introducing Server Components Dan Abramov and Lauren Tan (2020) No tienes que construir toda tu página con React.

Te permite agrupar componentes, pero no prescribe cómo hacer el enrutamiento y la obtención de datos. Para construir una aplicación completa en React, recomendamos un framework full-stack de React como Next.js o Remix . confs/[slug].js import { db } from './database.js' ; import { Suspense } from 'react' ; async function ConferencePage ( { slug } ) { const conf = await db . Confs . find ( { slug } ) ; return ( < ConferenceLayout conf = { conf } > < Suspense fallback = { < TalksLoading /> } > < Talks confId = { conf . id } /> </ Suspense > </ ConferenceLayout > ) ; } async function Talks ( { confId } ) { const talks = await db . Talks . findAll ( { confId } ) ; const videos = talks . map ( talk => talk . video ) ; return < SearchableVideoList videos = { videos } /> ; } example.com / confs/react-conf-2021 React Conf 2021 React Conf 2019 Buscar 19 Videos React Conf React 18 Keynote The React Team React Conf React 18 for App Developers Shruti Kapoor React Conf Streaming Server Rendering with Suspense Shaundai Person React Conf The First React Working Group Aakansha Doshi React Conf React Developer Tooling Brian Vaughn React Conf React without memo Xuan Huang (黄玄) React Conf React Docs Keynote Rachel Nabors React Conf Things I Learnt from the New React Docs Debbie O'Brien React Conf Learning in the Browser Sarah Rainsberger React Conf The ROI of Designing with React Linton Ye React Conf Interactive Playgrounds with React Delba de Oliveira React Conf Re-introducing Relay Robert Balicki React Conf React Native Desktop Eric Rozell and Steven Moyes React Conf On-device Machine Learning for React Native Roman Rädle React Conf React 18 for External Store Libraries Daishi Kato React Conf Building Accessible Components with React 18 Diego Haz React Conf Accessible Japanese Form Components with React Tafu Nakazaki React Conf UI Tools for Artists Lyle Troxell React Conf Hydrogen + React 18 Helen Lin React también es una arquitectura. Los frameworks que la implementan te permiten obtener datos en componentes asíncronos que se ejecutan en el servidor o incluso durante la compilación. Lee datos de un archivo o una base de datos y pásalos hacia abajo a tus componentes interactivos. Comienza a usar un framework Utiliza lo mejor de cada plataforma A las personas les encantan las aplicaciones web y nativas por razones diferentes. React te permite construir tanto aplicaciones web como nativas utilizando las mismas habilidades. Se apoya en las fortalezas únicas de cada plataforma para permitir que tus interfaces se sientan naturales en cada una de ellas. example.com Mantente fiel a la web Las personas esperan que las páginas de las aplicaciones web carguen rápidamente. En el servidor, React te permite servir HTML bajo demanda mientras aún estás cargando datos, rellenando progresivamente el contendido faltante antes de que cargue ningún código de JavaScript. En el cliente, React puede usar APIs web estándares para mantener tu interfaz de usuario responsiva incluso en medio del renderizado. 2:19 AM Logra una UI realmente nativa Las personas esperan que las aplicaciones nativas se vean y se sientan como su plataforma. React Native y Expo te permiten construir aplicaciones en React para Android, iOS y más. Lucen y se sienten como nativas porque sus UIs son realmente nativas. No es una vista web: tus componentes de React renderizan vistas reales de Android e iOS provistas por la plataforma. Con React, puedes ser un desarrollador web y de aplicaciones nativas. Tu equipo puede producir para muchas plataformas sin sacrificar la experiencia de usuario. Tu organización puede tender puentes para romper el aislamiento entre plataformas y formar equipos que estén a cargo de funcionalidades completas de extremo a extremo. Construye para plataformas nativas Actualiza cuando el futuro esté listo React atiende los cambios con cuidado. Cada commit de React se prueba en escenarios críticos para el negocio con más de mil millones de usuarios. Más de 100 000 componentes de React en Meta ayudan a validar cada estrategia de migración. El equipo de React siempre está investigando como mejorar React. Algunas investigaciones toman años en arrojar resultados. React tiene el listón alto para llevar una idea de investigación a producción. Solo enfoques probados se vuelven parte de React.

Glossary — Python 3.14.2 documentation Theme Auto Light Dark Previous topic Deprecations Next topic About this documentation This page Report a bug Show source Navigation index modules | next | previous | Python » 3.14.2 Documentation » Glossary | Theme Auto Light Dark | Glossary ¶ >>> ¶ The default Python prompt of the interactive shell. Often seen for code examples which can be executed interactively in the interpreter. ... ¶ Can refer to: The default Python prompt of the interactive shell when entering the code for an indented code block, when within a pair of matching left and right delimiters (parentheses, square brackets, curly braces or triple quotes), or after specifying a decorator. The three dots form of the Ellipsis object. abstract base class ¶ Abstract base classes complement duck-typing by providing a way to define interfaces when other techniques like hasattr() would be clumsy or subtly wrong (for example with magic methods ). ABCs introduce virtual subclasses, which are classes that don’t inherit from a class but are still recognized by isinstance() and issubclass() ; see the abc module documentation. Python comes with many built-in ABCs for data structures (in the collections.abc module), numbers (in the numbers module), streams (in the io module), import finders and loaders (in the importlib.abc module). You can create your own ABCs with the abc module. annotate function ¶ A function that can be called to retrieve the annotations of an object. This function is accessible as the __annotate__ attribute of functions, classes, and modules. Annotate functions are a subset of evaluate functions . annotation ¶ A label associated with a variable, a class attribute or a function parameter or return value, used by convention as a type hint . Annotations of local variables cannot be accessed at runtime, but annotations of global variables, class attributes, and functions can be retrieved by calling annotationlib.get_annotations() on modules, classes, and functions, respectively. See variable annotation , function annotation , PEP 484 , PEP 526 , and PEP 649 , which describe this functionality. Also see Annotations Best Practices for best practices on working with annotations. argument ¶ A value passed to a function (or method ) when calling the function. There are two kinds of argument: keyword argument : an argument preceded by an identifier (e.g. name= ) in a function call or passed as a value in a dictionary preceded by ** . For example, 3 and 5 are both keyword arguments in the following calls to complex() : complex ( real = 3 , imag = 5 ) complex ( ** { 'real' : 3 , 'imag' : 5 }) positional argument : an argument that is not a keyword argument. Positional arguments can appear at the beginning of an argument list and/or be passed as elements of an iterable preceded by * . For example, 3 and 5 are both positional arguments in the following calls: complex ( 3 , 5 ) complex ( * ( 3 , 5 )) Arguments are assigned to the named local variables in a function body. See the Calls section for the rules governing this assignment. Syntactically, any expression can be used to represent an argument; the evaluated value is assigned to the local variable. See also the parameter glossary entry, the FAQ question on the difference between arguments and parameters , and PEP 362 . asynchronous context manager ¶ An object which controls the environment seen in an async with statement by defining __aenter__() and __aexit__() methods. Introduced by PEP 492 . asynchronous generator ¶ A function which returns an asynchronous generator iterator . It looks like a coroutine function defined with async def except that it contains yield expressions for producing a series of values usable in an async for loop. Usually refers to an asynchronous generator function, but may refer to an asynchronous generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity. An asynchronous generator function may contain await expressions as well as async for , and async with statements. asynchronous generator iterator ¶ An object created by an asynchronous generator function. This is an asynchronous iterator which when called using the __anext__() method returns an awaitable object which will execute the body of the asynchronous generator function until the next yield expression. Each yield temporarily suspends processing, remembering the execution state (including local variables and pending try-statements). When the asynchronous generator iterator effectively resumes with another awaitable returned by __anext__() , it picks up where it left off. See PEP 492 and PEP 525 . asynchronous iterable ¶ An object, that can be used in an async for statement. Must return an asynchronous iterator from its __aiter__() method. Introduced by PEP 492 . asynchronous iterator ¶ An object that implements the __aiter__() and __anext__() methods. __anext__() must return an awaitable object. async for resolves the awaitables returned by an asynchronous iterator’s __anext__() method until it raises a StopAsyncIteration exception. Introduced by PEP 492 . atomic operation ¶ An operation that appears to execute as a single, indivisible step: no other thread can observe it half-done, and its effects become visible all at once. Python does not guarantee that high-level statements are atomic (for example, x += 1 performs multiple bytecode operations and is not atomic). Atomicity is only guaranteed where explicitly documented. See also race condition and data race . attached thread state ¶ A thread state that is active for the current OS thread. When a thread state is attached, the OS thread has access to the full Python C API and can safely invoke the bytecode interpreter. Unless a function explicitly notes otherwise, attempting to call the C API without an attached thread state will result in a fatal error or undefined behavior. A thread state can be attached and detached explicitly by the user through the C API, or implicitly by the runtime, including during blocking C calls and by the bytecode interpreter in between calls. On most builds of Python, having an attached thread state implies that the caller holds the GIL for the current interpreter, so only one OS thread can have an attached thread state at a given moment. In free-threaded builds of Python, threads can concurrently hold an attached thread state, allowing for true parallelism of the bytecode interpreter. attribute ¶ A value associated with an object which is usually referenced by name using dotted expressions. For example, if an object o has an attribute a it would be referenced as o.a . It is possible to give an object an attribute whose name is not an identifier as defined by Names (identifiers and keywords) , for example using setattr() , if the object allows it. Such an attribute will not be accessible using a dotted expression, and would instead need to be retrieved with getattr() . awaitable ¶ An object that can be used in an await expression. Can be a coroutine or an object with an __await__() method. See also PEP 492 . BDFL ¶ Benevolent Dictator For Life, a.k.a. Guido van Rossum , Python’s creator. binary file ¶ A file object able to read and write bytes-like objects . Examples of binary files are files opened in binary mode ( 'rb' , 'wb' or 'rb+' ), sys.stdin.buffer , sys.stdout.buffer , and instances of io.BytesIO and gzip.GzipFile . See also text file for a file object able to read and write str objects. borrowed reference ¶ In Python’s C API, a borrowed reference is a reference to an object, where the code using the object does not own the reference. It becomes a dangling pointer if the object is destroyed. For example, a garbage collection can remove the last strong reference to the object and so destroy it. Calling Py_INCREF() on the borrowed reference is recommended to convert it to a strong reference in-place, except when the object cannot be destroyed before the last usage of the borrowed reference. The Py_NewRef() function can be used to create a new strong reference . bytes-like object ¶ An object that supports the Buffer Protocol and can export a C- contiguous buffer. This includes all bytes , bytearray , and array.array objects, as well as many common memoryview objects. Bytes-like objects can be used for various operations that work with binary data; these include compression, saving to a binary file, and sending over a socket. Some operations need the binary data to be mutable. The documentation often refers to these as “read-write bytes-like objects”. Example mutable buffer objects include bytearray and a memoryview of a bytearray . Other operations require the binary data to be stored in immutable objects (“read-only bytes-like objects”); examples of these include bytes and a memoryview of a bytes object. bytecode ¶ Python source code is compiled into bytecode, the internal representation of a Python program in the CPython interpreter. The bytecode is also cached in .pyc files so that executing the same file is faster the second time (recompilation from source to bytecode can be avoided). This “intermediate language” is said to run on a virtual machine that executes the machine code corresponding to each bytecode. Do note that bytecodes are not expected to work between different Python virtual machines, nor to be stable between Python releases. A list of bytecode instructions can be found in the documentation for the dis module . callable ¶ A callable is an object that can be called, possibly with a set of arguments (see argument ), with the following syntax: callable ( argument1 , argument2 , argumentN ) A function , and by extension a method , is a callable. An instance of a class that implements the __call__() method is also a callable. callback ¶ A subroutine function which is passed as an argument to be executed at some point in the future. class ¶ A template for creating user-defined objects. Class definitions normally contain method definitions which operate on instances of the class. class variable ¶ A variable defined in a class and intended to be modified only at class level (i.e., not in an instance of the class). closure variable ¶ A free variable referenced from a nested scope that is defined in an outer scope rather than being resolved at runtime from the globals or builtin namespaces. May be explicitly defined with the nonlocal keyword to allow write access, or implicitly defined if the variable is only being read. For example, in the inner function in the following code, both x and print are free variables , but only x is a closure variable : def outer (): x = 0 def inner (): nonlocal x x += 1 print ( x ) return inner Due to the codeobject.co_freevars attribute (which, despite its name, only includes the names of closure variables rather than listing all referenced free variables), the more general free variable term is sometimes used even when the intended meaning is to refer specifically to closure variables. complex number ¶ An extension of the familiar real number system in which all numbers are expressed as a sum of a real part and an imaginary part. Imaginary numbers are real multiples of the imaginary unit (the square root of -1 ), often written i in mathematics or j in engineering. Python has built-in support for complex numbers, which are written with this latter notation; the imaginary part is written with a j suffix, e.g., 3+1j . To get access to complex equivalents of the math module, use cmath . Use of complex numbers is a fairly advanced mathematical feature. If you’re not aware of a need for them, it’s almost certain you can safely ignore them. concurrency ¶ The ability of a computer program to perform multiple tasks at the same time. Python provides libraries for writing programs that make use of different forms of concurrency. asyncio is a library for dealing with asynchronous tasks and coroutines. threading provides access to operating system threads and multiprocessing to operating system processes. Multi-core processors can execute threads and processes on different CPU cores at the same time (see parallelism ). concurrent modification ¶ When multiple threads modify shared data at the same time. Concurrent modification without proper synchronization can cause race conditions , and might also trigger a data race , data corruption, or both. context ¶ This term has different meanings depending on where and how it is used. Some common meanings: The temporary state or environment established by a context manager via a with statement. The collection of key­value bindings associated with a particular contextvars.Context object and accessed via ContextVar objects. Also see context variable . A contextvars.Context object. Also see current context . context management protocol ¶ The __enter__() and __exit__() methods called by the with statement. See PEP 343 . context manager ¶ An object which implements the context management protocol and controls the environment seen in a with statement. See PEP 343 . context variable ¶ A variable whose value depends on which context is the current context . Values are accessed via contextvars.ContextVar objects. Context variables are primarily used to isolate state between concurrent asynchronous tasks. contiguous ¶ A buffer is considered contiguous exactly if it is either C-contiguous or Fortran contiguous . Zero-dimensional buffers are C and Fortran contiguous. In one-dimensional arrays, the items must be laid out in memory next to each other, in order of increasing indexes starting from zero. In multidimensional C-contiguous arrays, the last index varies the fastest when visiting items in order of memory address. However, in Fortran contiguous arrays, the first index varies the fastest. coroutine ¶ Coroutines are a more generalized form of subroutines. Subroutines are entered at one point and exited at another point. Coroutines can be entered, exited, and resumed at many different points. They can be implemented with the async def statement. See also PEP 492 . coroutine function ¶ A function which returns a coroutine object. A coroutine function may be defined with the async def statement, and may contain await , async for , and async with keywords. These were introduced by PEP 492 . CPython ¶ The canonical implementation of the Python programming language, as distributed on python.org . The term “CPython” is used when necessary to distinguish this implementation from others such as Jython or IronPython. current context ¶ The context ( contextvars.Context object) that is currently used by ContextVar objects to access (get or set) the values of context variables . Each thread has its own current context. Frameworks for executing asynchronous tasks (see asyncio ) associate each task with a context which becomes the current context whenever the task starts or resumes execution. cyclic isolate ¶ A subgroup of one or more objects that reference each other in a reference cycle, but are not referenced by objects outside the group. The goal of the cyclic garbage collector is to identify these groups and break the reference cycles so that the memory can be reclaimed. data race ¶ A situation where multiple threads access the same memory location concurrently, at least one of the accesses is a write, and the threads do not use any synchronization to control their access. Data races lead to non-deterministic behavior and can cause data corruption. Proper use of locks and other synchronization primitives prevents data races. Note that data races can only happen in native code, but that native code might be exposed in a Python API. See also race condition and thread-safe . deadlock ¶ A situation in which two or more tasks (threads, processes, or coroutines) wait indefinitely for each other to release resources or complete actions, preventing any from making progress. For example, if thread A holds lock 1 and waits for lock 2, while thread B holds lock 2 and waits for lock 1, both threads will wait indefinitely. In Python this often arises from acquiring multiple locks in conflicting orders or from circular join/await dependencies. Deadlocks can be avoided by always acquiring multiple locks in a consistent order. See also lock and reentrant . decorator ¶ A function returning another function, usually applied as a function transformation using the @wrapper syntax. Common examples for decorators are classmethod() and staticmethod() . The decorator syntax is merely syntactic sugar, the following two function definitions are semantically equivalent: def f ( arg ): ... f = staticmethod ( f ) @staticmethod def f ( arg ): ... The same concept exists for classes, but is less commonly used there. See the documentation for function definitions and class definitions for more about decorators. descriptor ¶ Any object which defines the methods __get__() , __set__() , or __delete__() . When a class attribute is a descriptor, its special binding behavior is triggered upon attribute lookup. Normally, using a.b to get, set or delete an attribute looks up the object named b in the class dictionary for a , but if b is a descriptor, the respective descriptor method gets called. Understanding descriptors is a key to a deep understanding of Python because they are the basis for many features including functions, methods, properties, class methods, static methods, and reference to super classes. For more information about descriptors’ methods, see Implementing Descriptors or the Descriptor How To Guide . dictionary ¶ An associative array, where arbitrary keys are mapped to values. The keys can be any object with __hash__() and __eq__() methods. Called a hash in Perl. dictionary comprehension ¶ A compact way to process all or part of the elements in an iterable and return a dictionary with the results. results = {n: n ** 2 for n in range(10)} generates a dictionary containing key n mapped to value n ** 2 . See Displays for lists, sets and dictionaries . dictionary view ¶ The objects returned from dict.keys() , dict.values() , and dict.items() are called dictionary views. They provide a dynamic view on the dictionary’s entries, which means that when the dictionary changes, the view reflects these changes. To force the dictionary view to become a full list use list(dictview) . See Dictionary view objects . docstring ¶ A string literal which appears as the first expression in a class, function or module. While ignored when the suite is executed, it is recognized by the compiler and put into the __doc__ attribute of the enclosing class, function or module. Since it is available via introspection, it is the canonical place for documentation of the object. duck-typing ¶ A programming style which does not look at an object’s type to determine if it has the right interface; instead, the method or attribute is simply called or used (“If it looks like a duck and quacks like a duck, it must be a duck.”) By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance() . (Note, however, that duck-typing can be complemented with abstract base classes .) Instead, it typically employs hasattr() tests or EAFP programming. dunder ¶ An informal short-hand for “double underscore”, used when talking about a special method . For example, __init__ is often pronounced “dunder init”. EAFP ¶ Easier to ask for forgiveness than permission. This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements. The technique contrasts with the LBYL style common to many other languages such as C. evaluate function ¶ A function that can be called to evaluate a lazily evaluated attribute of an object, such as the value of type aliases created with the type statement. expression ¶ A piece of syntax which can be evaluated to some value. In other words, an expression is an accumulation of expression elements like literals, names, attribute access, operators or function calls which all return a value. In contrast to many other languages, not all language constructs are expressions. There are also statement s which cannot be used as expressions, such as while . Assignments are also statements, not expressions. extension module ¶ A module written in C or C++, using Python’s C API to interact with the core and with user code. f-string ¶ f-strings ¶ String literals prefixed with f or F are commonly called “f-strings” which is short for formatted string literals . See also PEP 498 . file object ¶ An object exposing a file-oriented API (with methods such as read() or write() ) to an underlying resource. Depending on the way it was created, a file object can mediate access to a real on-disk file or to another type of storage or communication device (for example standard input/output, in-memory buffers, sockets, pipes, etc.). File objects are also called file-like objects or streams . There are actually three categories of file objects: raw binary files , buffered binary files and text files . Their interfaces are defined in the io module. The canonical way to create a file object is by using the open() function. file-like object ¶ A synonym for file object . filesystem encoding and error handler ¶ Encoding and error handler used by Python to decode bytes from the operating system and encode Unicode to the operating system. The filesystem encoding must guarantee to successfully decode all bytes below 128. If the file system encoding fails to provide this guarantee, API functions can raise UnicodeError . The sys.getfilesystemencoding() and sys.getfilesystemencodeerrors() functions can be used to get the filesystem encoding and error handler. The filesystem encoding and error handler are configured at Python startup by the PyConfig_Read() function: see filesystem_encoding and filesystem_errors members of PyConfig . See also the locale encoding . finder ¶ An object that tries to find the loader for a module that is being imported. There are two types of finder: meta path finders for use with sys.meta_path , and path entry finders for use with sys.path_hooks . See Finders and loaders and importlib for much more detail. floor division ¶ Mathematical division that rounds down to nearest integer. The floor division operator is // . For example, the expression 11 // 4 evaluates to 2 in contrast to the 2.75 returned by float true division. Note that (-11) // 4 is -3 because that is -2.75 rounded downward . See PEP 238 . free threading ¶ A threading model where multiple threads can run Python bytecode simultaneously within the same interpreter. This is in contrast to the global interpreter lock which allows only one thread to execute Python bytecode at a time. See PEP 703 . free variable ¶ Formally, as defined in the language execution model , a free variable is any variable used in a namespace which is not a local variable in that namespace. See closure variable for an example. Pragmatically, due to the name of the codeobject.co_freevars attribute, the term is also sometimes used as a synonym for closure variable . function ¶ A series of statements which returns some value to a caller. It can also be passed zero or more arguments which may be used in the execution of the body. See also parameter , method , and the Function definitions section. function annotation ¶ An annotation of a function parameter or return value. Function annotations are usually used for type hints : for example, this function is expected to take two int arguments and is also expected to have an int return value: def sum_two_numbers ( a : int , b : int ) -> int : return a + b Function annotation syntax is explained in section Function definitions . See variable annotation and PEP 484 , which describe this functionality. Also see Annotations Best Practices for best practices on working with annotations. __future__ ¶ A future statement , from __future__ import <feature> , directs the compiler to compile the current module using syntax or semantics that will become standard in a future release of Python. The __future__ module documents the possible values of feature . By importing this module and evaluating its variables, you can see when a new feature was first added to the language and when it will (or did) become the default: >>> import __future__ >>> __future__ . division _Feature((2, 2, 0, 'alpha', 2), (3, 0, 0, 'alpha', 0), 8192) garbage collection ¶ The process of freeing memory when it is not used anymore. Python performs garbage collection via reference counting and a cyclic garbage collector that is able to detect and break reference cycles. The garbage collector can be controlled using the gc module. generator ¶ A function which returns a generator iterator . It looks like a normal function except that it contains yield expressions for producing a series of values usable in a for-loop or that can be retrieved one at a time with the next() function. Usually refers to a generator function, but may refer to a generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity. generator iterator ¶ An object created by a generator function. Each yield temporarily suspends processing, remembering the execution state (including local variables and pending try-statements). When the generator iterator resumes, it picks up where it left off (in contrast to functions which start fresh on every invocation). generator expression ¶ An expression that returns an iterator . It looks like a normal expression followed by a for clause defining a loop variable, range, and an optional if clause. The combined expression generates values for an enclosing function: >>> sum ( i * i for i in range ( 10 )) # sum of squares 0, 1, 4, ... 81 285 generic function ¶ A function composed of multiple functions implementing the same operation for different types. Which implementation should be used during a call is determined by the dispatch algorithm. See also the single dispatch glossary entry, the functools.singledispatch() decorator, and PEP 443 . generic type ¶ A type that can be parameterized; typically a container class such as list or dict . Used for type hints and annotations . For more details, see generic alias types , PEP 483 , PEP 484 , PEP 585 , and the typing module. GIL ¶ See global interpreter lock . global interpreter lock ¶ The mechanism used by the CPython interpreter to assure that only one thread executes Python bytecode at a time. This simplifies the CPython implementation by making the object model (including critical built-in types such as dict ) implicitly safe against concurrent access. Locking the entire interpreter makes it easier for the interpreter to be multi-threaded, at the expense of much of the parallelism afforded by multi-processor machines. However, some extension modules, either standard or third-party, are designed so as to release the GIL when doing computationally intensive tasks such as compression or hashing. Also, the GIL is always released when doing I/O. As of Python 3.13, the GIL can be disabled using the --disable-gil build configuration. After building Python with this option, code must be run with -X gil=0 or after setting the PYTHON_GIL=0 environment variable. This feature enables improved performance for multi-threaded applications and makes it easier to use multi-core CPUs efficiently. For more details, see PEP 703 . In prior versions of Python’s C API, a function might declare that it requires the GIL to be held in order to use it. This refers to having an attached thread state . global state ¶ Data that is accessible throughout a program, such as module-level variables, class variables, or C static variables in extension modules . In multi-threaded programs, global state shared between threads typically requires synchronization to avoid race conditions and data races . hash-based pyc ¶ A bytecode cache file that uses the hash rather than the last-modified time of the corresponding source file to determine its validity. See Cached bytecode invalidation . hashable ¶ An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() method). Hashable objects which compare equal must have the same hash value. Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally. Most of Python’s immutable built-in objects are hashable; mutable containers (such as lists or dictionaries) are not; immutable containers (such as tuples and frozensets) are only hashable if their elements are hashable. Objects which are instances of user-defined classes are hashable by default. They all compare unequal (except with themselves), and their hash value is derived from their id() . IDLE ¶ An Integrated Development and Learning Environment for Python. IDLE — Python editor and shell is a basic editor and interpreter environment which ships with the standard distribution of Python. immortal ¶ Immortal objects are a CPython implementation detail introduced in PEP 683 . If an object is immortal, its reference count is never modified, and therefore it is never deallocated while the interpreter is running. For example, True and None are immortal in CPython. Immortal objects can be identified via sys._is_immortal() , or via PyUnstable_IsImmortal() in the C API. immutable ¶ An object with a fixed value. Immutable objects include numbers, strings and tuples. Such an object cannot be altered. A new object has to be created if a different value has to be stored. They play an important role in places where a constant hash value is needed, for example as a key in a dictionary. Immutable objects are inherently thread-safe because their state cannot be modified after creation, eliminating concerns about improperly synchronized concurrent modification . import path ¶ A list of locations (or path entries ) that are searched by the path based finder for modules to import. During import, this list of locations usually comes from sys.path , but for subpackages it may also come from the parent package’s __path__ attribute. importing ¶ The process by which Python code in one module is made available to Python code in another module. importer ¶ An object that both finds and loads a module; both a finder and loader object. interactive ¶ Python has an interactive interpreter which means you can enter statements and expressions at the interpreter prompt, immediately execute them and see their results. Just launch python with no arguments (possibly by selecting it from your computer’s main menu). It is a very powerful way to test out new ideas or inspect modules and packages (remember help(x) ). For more on interactive mode, see Interactive Mode . interpreted ¶ Python is an interpreted language, as opposed to a compiled one, though the distinction can be blurry because of the presence of the bytecode compiler. This means that source files can be run directly without explicitly creating an executable which is then run. Interpreted languages typically have a shorter development/debug cycle than compiled ones, though their programs generally also run more slowly. See also interactive . interpreter shutdown ¶ When asked to shut down, the Python interpreter enters a special phase where it gradually releases all allocated resources, such as modules and various critical internal structures. It also makes several calls to the garbage collector . This can trigger the execution of code in user-defined destructors or weakref callbacks. Code executed during the shutdown phase can encounter various exceptions as the resources it relies on may not function anymore (common examples are library modules or the warnings machinery). The main reason for interpreter shutdown is that the __main__ module or the script being run has finished executing. iterable ¶ An object capable of returning its members one at a time. Examples of iterables include all sequence types (such as list , str , and tuple ) and some non-sequence types like dict , file objects , and objects of any classes you define with an __iter__() method or with a __getitem__() method that implements sequence semantics. Iterables can be used in a for loop and in many other places where a sequence is needed ( zip() , map() , …). When an iterable object is passed as an argument to the built-in function iter() , it returns an iterator for the object. This iterator is good for one pass over the set of values. When using iterables, it is usually not necessary to call iter() or deal with iterator objects yourself. The for statement does that automatically for you, creating a temporary unnamed variable to hold the iterator for the duration of the loop. See also iterator , sequence , and generator . iterator ¶ An object representing a stream of data. Repeated calls to the iterator’s __next__() method (or passing it to the built-in function next() ) return successive items in the stream. When no more data are available a StopIteration exception is raised instead. At this point, the iterator object is exhausted and any further calls to its __next__() method just raise StopIteration again. Iterators are required to have an __iter__() method that returns the iterator object itself so every iterator is also iterable and may be used in most places where other iterables are accepted. One notable exception is code which attempts multiple iteration passes. A container object (such as a list ) produces a fresh new iterator each time you pass it to the iter() function or use it in a for loop. Attempting this with an iterator will just return the same exhausted iterator object used in the previous iteration pass, making it appear like an empty container. More information can be found in Iterator Types . CPython implementation detail: CPython does not consistently apply the requirement that an iterator define __iter__() . And also please note that free-threaded CPython does not guarantee thread-safe behavior of iterator operations. key function ¶ A key function or collation function is a callable that returns a value used for sorting or ordering. For example, locale.strxfrm() is used to produce a sort key that is aware of locale specific sort conventions. A number of tools in Python accept key functions to control how elements are ordered or grouped. They include min() , max() , sorted() , list.sort() , heapq.merge() , heapq.nsmallest() , heapq.nlargest() , and itertools.groupby() . There are several ways to create a key function. For example. the str.casefold() method can serve as a key function for case insensitive sorts. Alternatively, a key function can be built from a lambda expression such as lambda r: (r[0], r[2]) . Also, operator.attrgetter() , operator.itemgetter() , and operator.methodcaller() are three key function constructors. See the Sorting HOW TO for examples of how to create and use key functions. keyword argument ¶ See argument . lambda ¶ An anonymous inline function consisting of a single expression which is evaluated when the function is called. The syntax to create a lambda function is lambda [parameters]: expression LBYL ¶ Look before you leap. This coding style explicitly tests for pre-conditions before making calls or lookups. This style contrasts with the EAFP approach and is characterized by the presence of many if statements. In a multi-threaded environment, the LBYL approach can risk introducing a race condition between “the looking” and “the leaping”. For example, the code, if key in mapping: return mapping[key] can fail if another thread removes key from mapping after the test, but before the lookup. This issue can be solved with locks or by using the EAFP approach. See also thread-safe . lexical analyzer ¶ Formal name for the tokenizer ; see token . list ¶ A built-in Python sequence . Despite its name it is more akin to an array in other languages than to a linked list since access to elements is O (1). list comprehension ¶ A compact way to process all or part of the elements in a sequence and return a list with the results. result = ['{:#04x}'.format(x) for x in range(256) if x % 2 == 0] generates a list of strings containing even hex numbers (0x..) in the range from 0 to 255. The if clause is optional. If omitted, all elements in range(256) are processed. lock ¶ A synchronization primitive that allows only one thread at a time to access a shared resource. A thread must acquire a lock before accessing the protected resource and release it afterward. If a thread attempts to acquire a lock that is already held by another thread, it will block until the lock becomes available. Python’s threading module provides Lock (a basic lock) and RLock (a reentrant lock). Locks are used to prevent race conditions and ensure thread-safe access to shared data. Alternative design patterns to locks exist such as queues, producer/consumer patterns, and thread-local state. See also deadlock , and reentrant . loader ¶ An object that loads a module. It must define the exec_module() and create_module() methods to implement the Loader interface. A loader is typically returned by a finder . See also: Finders and loaders importlib.abc.Loader PEP 302 locale encoding ¶ On Unix, it is the encoding of the LC_CTYPE locale. It can be set with locale.setlocale(locale.LC_CTYPE, new_locale) . On Windows, it is the ANSI code page (ex: "cp1252" ). On Android and VxWorks, Python uses "utf-8" as the locale encoding. locale.getencoding() can be used to get the locale encoding. See also the filesystem encoding and error handler . magic method ¶ An informal synonym for special method . mapping ¶ A container object that supports arbitrary key lookups and implements the methods specified in the collections.abc.Mapping or collections.abc.MutableMapping abstract base classes . Examples include dict , collections.defaultdict , collections.OrderedDict and collections.Counter . meta path finder ¶ A finder returned by a search of sys.meta_path . Meta path finders are related to, but different from path entry finders . See importlib.abc.MetaPathFinder for the methods that meta path finders implement. metaclass ¶ The class of a class. Class definitions create a class name, a class dictionary, and a list of base classes. The metaclass is responsible for taking those three arguments and creating the class. Most object oriented programming languages provide a default implementation. What makes Python special is that it is possible to create custom metaclasses. Most users never need this tool, but when the need arises, metaclasses can provide powerful, elegant solutions. They have been used for logging attribute access, adding thread-safety, tracking object creation, implementing singletons, and many other tasks. More information can be found in Metaclasses . method ¶ A function which is defined inside a class body. If called as an attribute of an instance of that class, the method will get the instance object as its first argument (which is usually called self ). See function and nested scope . method resolution order ¶ Method Resolution Order is the order in which base classes are searched for a member during lookup. See The Python 2.3 Method Resolution Order for details of the algorithm used by the Python interpreter since the 2.3 release. module ¶ An object that serves as an organizational unit of Python code. Modules have a namespace containing arbitrary Python objects. Modules are loaded into Python by the process of importing . See also package . module spec ¶ A namespace containing the import-related information used to load a module. An instance of importlib.machinery.ModuleSpec . See also Module specs . MRO ¶ See method resolution order . mutable ¶ An object with state that is allowed to change during the course of the program. In multi-threaded programs, mutable objects that are shared between threads require careful synchronization to avoid race conditions . See also immutable , thread-safe , and concurrent modification . named tuple ¶ The term “named tuple” applies to any type or class that inherits from tuple and whose indexable elements are also accessible using named attributes. The type or class may have other features as well. Several built-in types are named tuples, including the values returned by time.localtime() and os.stat() . Another example is sys.float_info : >>> sys . float_info [ 1 ] # indexed access 1024 >>> sys . float_info . max_exp # named field access 1024 >>> isinstance ( sys . float_info , tuple ) # kind of tuple True Some named tuples are built-in types (such as the above examples). Alternatively, a named tuple can be created from a regular class definition that inherits from tuple and that defines named fields. Such a class can be written by hand, or it can be created by inheriting typing.NamedTuple , or with the factory function collections.namedtuple() . The latter techniques also add some extra methods that may not be found in hand-written or built-in named tuples. namespace ¶ The place where a variable is stored. Namespaces are implemented as dictionaries. There are the local, global and built-in namespaces as well as nested namespaces in objects (in methods). Namespaces support modularity by preventing naming conflicts. For instance, the functions builtins.open and os.open() are distinguished by their namespaces. Namespaces also aid readability and maintainability by making it clear which module implements a function. For instance, writing random.seed() or itertools.islice() makes it clear that those functions are implemented by the random and itertools modules, respectively. namespace package ¶ A package which serves only as a container for subpackages. Namespace packages may have no physical representation, and specifically are not like a regular package because they have no __init__.py file. Namespace packages allow several individually installable packages to have a common parent package. Otherwise, it is recommended to use a regular package . For more information, see PEP 420 and Namespace packages . See also module . native code ¶ Code that is compiled to machine instructions and runs directly on the processor, as opposed to code that is interpreted or runs in a virtual machine. In the context of Python, native code typically refers to C, C++, Rust or Fortran code in extension modules that can be called from Python. See also extension module . nested scope ¶ The ability to refer to a variable in an enclosing definition. For instance, a function defined inside another function can refer to variables in the outer function. Note that nested scopes by default work only for reference and not for assignment. Local variables both read and write in the innermost scope. Likewise, global variables read and write to the global namespace. The nonlocal allows writing to outer scopes. new-style class ¶ Old name for the flavor of classes now used for all class objects. In earlier Python versions, only new-style classes could use Python’s newer, versatile features like __slots__ , descriptors, properties, __getattribute__() , class methods, and static methods. non-deterministic ¶ Behavior where the outcome of a program can vary between executions with the same inputs. In multi-threaded programs, non-deterministic behavior often results from race conditions where the relative timing or interleaving of threads affects the result. Proper synchronization using locks and other synchronization primitives helps ensure deterministic behavior. object ¶ Any data with state (attributes or value) and defined behavior (methods). Also the ultimate base class of any new-style class . optimized scope ¶ A scope where target local variable names are reliably known to the compiler when the code is compiled, allowing optimization of read and write access to these names. The local namespaces for functions, generators, coroutines, comprehensions, and generator expressions are optimized in this fashion. Note: most interpreter optimizations are applied to all scopes, only those relying on a known set of local and nonlocal variable names are restricted to optimized scopes. optional module ¶ An extension module that is part of the standard library , but may be absent in some builds of CPython , usually due to missing third-party libraries or because the module is not available for a given platform. See Requirements for optional modules for a list of optional modules that require third-party libraries. package ¶ A Python module which can contain submodules or recursively, subpackages. Technically, a package is a Python module with a __path__ attribute. See also regular package and namespace package . parallelism ¶ Executing multiple operations at the same time (e.g. on multiple CPU cores). In Python builds with the global interpreter lock (GIL) , only one thread runs Python bytecode at a time, so taking advantage of multiple CPU cores typically involves multiple processes (e.g. multiprocessing ) or native extensions that release the GIL. In free-threaded Python, multiple Python threads can run Python code simultaneously on different cores. parameter ¶ A named entity in a function (or method) definition that specifies an argument (or in some cases, arguments) that the function can accept. There are five kinds of parameter: positional-or-keyword : specifies an argument that can be passed either positionally or as a keyword argument . This is the default kind of parameter, for example foo and bar in the following: def func ( foo , bar = None ): ... positional-only : specifies an argument that can be supplied only by position. Positional-only parameters can be defined by including a / character in the parameter list of the function definition after them, for example posonly1 and posonly2 in the following: def func ( posonly1 , posonly2 , / , positional_or_keyword ): ... keyword-only : specifies an argument that can be supplied only by keyword. Keyword-only parameters can be defined by including a single var-positional parameter or bare * in the parameter list of the function definition before them, for example kw_only1 and kw_only2 in the following: def func ( arg , * , kw_only1 , kw_only2 ): ... var-positional : specifies that an arbitrary sequence of positional arguments can be provided (in addition to any positional arguments already accepted by other parameters). Such a parameter can be defined by prepending the parameter name with * , for example args in the following: def func ( * args , ** kwargs ): ... var-keyword : specifies that arbitrarily many keyword arguments can be provided (in addition to any keyword arguments already accepted by other parameters). Such a parameter can be defined by prepending the parameter name with ** , for example kwargs in the example above. Parameters can specify both optional and required arguments, as well as default values for some optional arguments. See also the argument glossary entry, the FAQ question on the difference between arguments and parameters , the inspect.Parameter class, the Function definitions section, and PEP 362 . path entry ¶ A single location on the import path which the path based finder consults to find modules for importing. path entry finder ¶ A finder returned by a callable on sys.path_hooks (i.e. a path entry hook ) which knows how to locate modules given a path entry . See importlib.abc.PathEntryFinder for the methods that path entry finders implement. path entry hook ¶ A callable on the sys.path_hooks list which returns a path entry finder if it knows how to find modules on a specific path entry . path based finder ¶ One of the default meta path finders which searches an import path for modules. path-like object ¶ An object representing a file system path. A path-like object is either a str or bytes object representing a path, or an object implementing the os.PathLike protocol. An object that supports the os.PathLike protocol can be converted to a str or bytes file system path by calling the os.fspath() function; os.fsdecode() and os.fsencode() can be used to guarantee a str or bytes result instead, respectively. Introduced by PEP 519 . PEP ¶ Python Enhancement Proposal. A PEP is a design document providing information to the Python community, or describing a new feature for Python or its processes or environment. PEPs should provide a concise technical specification and a rationale for proposed features. PEPs are intended to be the primary mechanisms for proposing major new features, for collecting community input on an issue, and for documenting the design decisions that have gone into Python. The PEP author is responsible for building consensus within the community and documenting dissenting opinions. See PEP 1 . portion ¶ A set of files in a single directory (possibly stored in a zip file) that contribute to a namespace package, as defined in PEP 420 . positional argument ¶ See argument . provisional API ¶ A provisional API is one which has been deliberately excluded from the standard library’s backwards compatibility guarantees. While major changes to such interfaces are not expected, as long as they are marked provisional, backwards incompatible changes (up to and including removal of the interface) may occur if deemed necessary by core developers. Such changes will not be made

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details).

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy.  They're called "defined terms," and we use them so that we don't have to repeat the same language again and again.  They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3.

This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us.

Simple statements | Theme Auto Light Dark | 7. Simple statements ¶ A simple statement is comprised within a single logical line. Several simple statements may occur on a single line separated by semicolons. The syntax for simple statements is: simple_stmt : expression_stmt | assert_stmt | assignment_stmt | augmented_assignment_stmt | annotated_assignment_stmt | pass_stmt | del_stmt | return_stmt | yield_stmt | raise_stmt | break_stmt | continue_stmt | import_stmt | future_stmt | global_stmt | nonlocal_stmt | type_stmt 7.1. Expression statements ¶ Expression statements are used (mostly interactively) to compute and write a value, or (usually) to call a procedure (a function that returns no meaningful result; in Python, procedures return the value None ). Other uses of expression statements are allowed and occasionally useful. The syntax for an expression statement is: expression_stmt : starred_expression An expression statement evaluates the expression list (which may be a single expression). In interactive mode, if the value is not None , it is converted to a string using the built-in repr() function and the resulting string is written to standard output on a line by itself (except if the result is None , so that procedure calls do not cause any output.) 7.2. Assignment statements ¶ Assignment statements are used to (re)bind names to values and to modify attributes or items of mutable objects: assignment_stmt : ( target_list "=" )+ ( starred_expression | yield_expression ) target_list : target ( "," target )* [ "," ] target : identifier | "(" [ target_list ] ")" | "[" [ target_list ] "]" | attributeref | subscription | slicing | "*" target (See section Primaries for the syntax definitions for attributeref , subscription , and slicing .) An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right. Assignment is defined recursively depending on the form of the target (list). When a target is part of a mutable object (an attribute reference, subscription or slicing), the mutable object must ultimately perform the assignment and decide about its validity, and may raise an exception if the assignment is unacceptable. The rules observed by various types and the exceptions raised are given with the definition of the object types (see section The standard type hierarchy ). Assignment of an object to a target list, optionally enclosed in parentheses or square brackets, is recursively defined as follows. If the target list is a single target with no trailing comma, optionally in parentheses, the object is assigned to that target. Else: If the target list contains one target prefixed with an asterisk, called a “starred” target: The object must be an iterable with at least as many items as there are targets in the target list, minus one. The first items of the iterable are assigned, from left to right, to the targets before the starred target. The final items of the iterable are assigned to the targets after the starred target. A list of the remaining items in the iterable is then assigned to the starred target (the list can be empty). Else: The object must be an iterable with the same number of items as there are targets in the target list, and the items are assigned, from left to right, to the corresponding targets. Assignment of an object to a single target is recursively defined as follows. If the target is an identifier (name): If the name does not occur in a global or nonlocal statement in the current code block: the name is bound to the object in the current local namespace. Otherwise: the name is bound to the object in the global namespace or the outer namespace determined by nonlocal , respectively. The name is rebound if it was already bound. This may cause the reference count for the object previously bound to the name to reach zero, causing the object to be deallocated and its destructor (if it has one) to be called. If the target is an attribute reference: The primary expression in the reference is evaluated. It should yield an object with assignable attributes; if this is not the case, TypeError is raised. That object is then asked to assign the assigned object to the given attribute; if it cannot perform the assignment, it raises an exception (usually but not necessarily AttributeError ). Note: If the object is a class instance and the attribute reference occurs on both sides of the assignment operator, the right-hand side expression, a.x can access either an instance attribute or (if no instance attribute exists) a class attribute. The left-hand side target a.x is always set as an instance attribute, creating it if necessary. Thus, the two occurrences of a.x do not necessarily refer to the same attribute: if the right-hand side expression refers to a class attribute, the left-hand side creates a new instance attribute as the target of the assignment: class Cls : x = 3 # class variable inst = Cls () inst . x = inst . x + 1 # writes inst.x as 4 leaving Cls.x as 3 This description does not necessarily apply to descriptor attributes, such as properties created with property() . If the target is a subscription: The primary expression in the reference is evaluated. It should yield either a mutable sequence object (such as a list) or a mapping object (such as a dictionary). Next, the subscript expression is evaluated. If the primary is a mutable sequence object (such as a list), the subscript must yield an integer. If it is negative, the sequence’s length is added to it. The resulting value must be a nonnegative integer less than the sequence’s length, and the sequence is asked to assign the assigned object to its item with that index. If the index is out of range, IndexError is raised (assignment to a subscripted sequence cannot add new items to a list). If the primary is a mapping object (such as a dictionary), the subscript must have a type compatible with the mapping’s key type, and the mapping is then asked to create a key/value pair which maps the subscript to the assigned object. This can either replace an existing key/value pair with the same key value, or insert a new key/value pair (if no key with the same value existed). For user-defined objects, the __setitem__() method is called with appropriate arguments. If the target is a slicing: The primary expression in the reference is evaluated. It should yield a mutable sequence object (such as a list). The assigned object should be a sequence object of the same type. Next, the lower and upper bound expressions are evaluated, insofar they are present; defaults are zero and the sequence’s length. The bounds should evaluate to integers. If either bound is negative, the sequence’s length is added to it. The resulting bounds are clipped to lie between zero and the sequence’s length, inclusive. Finally, the sequence object is asked to replace the slice with the items of the assigned sequence. The length of the slice may be different from the length of the assigned sequence, thus changing the length of the target sequence, if the target sequence allows it. CPython implementation detail: In the current implementation, the syntax for targets is taken to be the same as for expressions, and invalid syntax is rejected during the code generation phase, causing less detailed error messages. Although the definition of assignment implies that overlaps between the left-hand side and the right-hand side are ‘simultaneous’ (for example a, b = b, a swaps two variables), overlaps within the collection of assigned-to variables occur left-to-right, sometimes resulting in confusion. For instance, the following program prints [0, 2] : x = [ 0 , 1 ] i = 0 i , x [ i ] = 1 , 2 # i is updated, then x[i] is updated print ( x ) See also PEP 3132 - Extended Iterable Unpacking The specification for the *target feature. 7.2.1. Augmented assignment statements ¶ Augmented assignment is the combination, in a single statement, of a binary operation and an assignment statement: augmented_assignment_stmt : augtarget augop ( expression_list | yield_expression ) augtarget : identifier | attributeref | subscription | slicing augop : "+=" | "-=" | "*=" | "@=" | "/=" | "//=" | "%=" | "**=" | ">>=" | "<<=" | "&=" | "^=" | "|=" (See section Primaries for the syntax definitions of the last three symbols.) An augmented assignment evaluates the target (which, unlike normal assignment statements, cannot be an unpacking) and the expression list, performs the binary operation specific to the type of assignment on the two operands, and assigns the result to the original target. The target is only evaluated once. An augmented assignment statement like x += 1 can be rewritten as x = x + 1 to achieve a similar, but not exactly equal effect. In the augmented version, x is only evaluated once. Also, when possible, the actual operation is performed in-place , meaning that rather than creating a new object and assigning that to the target, the old object is modified instead. Unlike normal assignments, augmented assignments evaluate the left-hand side before evaluating the right-hand side. For example, a[i] += f(x) first looks-up a[i] , then it evaluates f(x) and performs the addition, and lastly, it writes the result back to a[i] . With the exception of assigning to tuples and multiple targets in a single statement, the assignment done by augmented assignment statements is handled the same way as normal assignments. Similarly, with the exception of the possible in-place behavior, the binary operation performed by augmented assignment is the same as the normal binary operations. For targets which are attribute references, the same caveat about class and instance attributes applies as for regular assignments. 7.2.2. Annotated assignment statements ¶ Annotation assignment is the combination, in a single statement, of a variable or attribute annotation and an optional assignment statement: annotated_assignment_stmt : augtarget ":" expression [ "=" ( starred_expression | yield_expression )] The difference from normal Assignment statements is that only a single target is allowed. The assignment target is considered “simple” if it consists of a single name that is not enclosed in parentheses. For simple assignment targets, if in class or module scope, the annotations are gathered in a lazily evaluated annotation scope . The annotations can be evaluated using the __annotations__ attribute of a class or module, or using the facilities in the annotationlib module. If the assignment target is not simple (an attribute, subscript node, or parenthesized name), the annotation is never evaluated. If a name is annotated in a function scope, then this name is local for that scope. Annotations are never evaluated and stored in function scopes. If the right hand side is present, an annotated assignment performs the actual assignment as if there was no annotation present. If the right hand side is not present for an expression target, then the interpreter evaluates the target except for the last __setitem__() or __setattr__() call. See also PEP 526 - Syntax for Variable Annotations The proposal that added syntax for annotating the types of variables (including class variables and instance variables), instead of expressing them through comments. PEP 484 - Type hints The proposal that added the typing module to provide a standard syntax for type annotations that can be used in static analysis tools and IDEs. Changed in version 3.8: Now annotated assignments allow the same expressions in the right hand side as regular assignments. Previously, some expressions (like un-parenthesized tuple expressions) caused a syntax error. Changed in version 3.14: Annotations are now lazily evaluated in a separate annotation scope . If the assignment target is not simple, annotations are never evaluated. 7.3. The assert statement ¶ Assert statements are a convenient way to insert debugging assertions into a program: assert_stmt : "assert" expression [ "," expression ] The simple form, assert expression , is equivalent to if __debug__ : if not expression : raise AssertionError The extended form, assert expression1, expression2 , is equivalent to if __debug__ : if not expression1 : raise AssertionError ( expression2 ) These equivalences assume that __debug__ and AssertionError refer to the built-in variables with those names. In the current implementation, the built-in variable __debug__ is True under normal circumstances, False when optimization is requested (command line option -O ). The current code generator emits no code for an assert statement when optimization is requested at compile time. Note that it is unnecessary to include the source code for the expression that failed in the error message; it will be displayed as part of the stack trace. Assignments to __debug__ are illegal. The value for the built-in variable is determined when the interpreter starts. 7.4. The pass statement ¶ pass_stmt : "pass" pass is a null operation — when it is executed, nothing happens. It is useful as a placeholder when a statement is required syntactically, but no code needs to be executed, for example: def f ( arg ): pass # a function that does nothing (yet) class C : pass # a class with no methods (yet) 7.5. The del statement ¶ del_stmt : "del" target_list Deletion is recursively defined very similar to the way assignment is defined. Rather than spelling it out in full details, here are some hints. Deletion of a target list recursively deletes each target, from left to right. Deletion of a name removes the binding of that name from the local or global namespace, depending on whether the name occurs in a global statement in the same code block. Trying to delete an unbound name raises a NameError exception. Deletion of attribute references, subscriptions and slicings is passed to the primary object involved; deletion of a slicing is in general equivalent to assignment of an empty slice of the right type (but even this is determined by the sliced object). Changed in version 3.2: Previously it was illegal to delete a name from the local namespace if it occurs as a free variable in a nested block. 7.6. The return statement ¶ return_stmt : "return" [ expression_list ] return may only occur syntactically nested in a function definition, not within a nested class definition. If an expression list is present, it is evaluated, else None is substituted. return leaves the current function call with the expression list (or None ) as return value. When return passes control out of a try statement with a finally clause, that finally clause is executed before really leaving the function. In a generator function, the return statement indicates that the generator is done and will cause StopIteration to be raised. The returned value (if any) is used as an argument to construct StopIteration and becomes the StopIteration.value attribute. In an asynchronous generator function, an empty return statement indicates that the asynchronous generator is done and will cause StopAsyncIteration to be raised. A non-empty return statement is a syntax error in an asynchronous generator function. 7.7. The yield statement ¶ yield_stmt : yield_expression A yield statement is semantically equivalent to a yield expression . The yield statement can be used to omit the parentheses that would otherwise be required in the equivalent yield expression statement. For example, the yield statements yield < expr > yield from < expr > are equivalent to the yield expression statements ( yield < expr > ) ( yield from < expr > ) Yield expressions and statements are only used when defining a generator function, and are only used in the body of the generator function. Using yield in a function definition is sufficient to cause that definition to create a generator function instead of a normal function. For full details of yield semantics, refer to the Yield expressions section. 7.8. The raise statement ¶ raise_stmt : "raise" [ expression [ "from" expression ]] If no expressions are present, raise re-raises the exception that is currently being handled, which is also known as the active exception . If there isn’t currently an active exception, a RuntimeError exception is raised indicating that this is an error. Otherwise, raise evaluates the first expression as the exception object. It must be either a subclass or an instance of BaseException . If it is a class, the exception instance will be obtained when needed by instantiating the class with no arguments. The type of the exception is the exception instance’s class, the value is the instance itself. A traceback object is normally created automatically when an exception is raised and attached to it as the __traceback__ attribute. You can create an exception and set your own traceback in one step using the with_traceback() exception method (which returns the same exception instance, with its traceback set to its argument), like so: raise Exception ( "foo occurred" ) . with_traceback ( tracebackobj ) The from clause is used for exception chaining: if given, the second expression must be another exception class or instance. If the second expression is an exception instance, it will be attached to the raised exception as the __cause__ attribute (which is writable). If the expression is an exception class, the class will be instantiated and the resulting exception instance will be attached to the raised exception as the __cause__ attribute. If the raised exception is not handled, both exceptions will be printed: >>> try : ... print ( 1 / 0 ) ... except Exception as exc : ... raise RuntimeError ( "Something bad happened" ) from exc ... Traceback (most recent call last): File "<stdin>" , line 2 , in <module> print ( 1 / 0 ) ~~^~~ ZeroDivisionError : division by zero The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<stdin>" , line 4 , in <module> raise RuntimeError ( "Something bad happened" ) from exc RuntimeError : Something bad happened A similar mechanism works implicitly if a new exception is raised when an exception is already being handled. An exception may be handled when an except or finally clause, or a with statement, is used. The previous exception is then attached as the new exception’s __context__ attribute: >>> try : ... print ( 1 / 0 ) ... except : ... raise RuntimeError ( "Something bad happened" ) ... Traceback (most recent call last): File "<stdin>" , line 2 , in <module> print ( 1 / 0 ) ~~^~~ ZeroDivisionError : division by zero During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>" , line 4 , in <module> raise RuntimeError ( "Something bad happened" ) RuntimeError : Something bad happened Exception chaining can be explicitly suppressed by specifying None in the from clause: >>> try : ... print ( 1 / 0 ) ... except : ... raise RuntimeError ( "Something bad happened" ) from None ... Traceback (most recent call last): File "<stdin>" , line 4 , in <module> RuntimeError : Something bad happened Additional information on exceptions can be found in section Exceptions , and information about handling exceptions is in section The try statement . Changed in version 3.3: None is now permitted as Y in raise X from Y . Added the __suppress_context__ attribute to suppress automatic display of the exception context. Changed in version 3.11: If the traceback of the active exception is modified in an except clause, a subsequent raise statement re-raises the exception with the modified traceback. Previously, the exception was re-raised with the traceback it had when it was caught. 7.9. The break statement ¶ break_stmt : "break" break may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop. It terminates the nearest enclosing loop, skipping the optional else clause if the loop has one. If a for loop is terminated by break , the loop control target keeps its current value. When break passes control out of a try statement with a finally clause, that finally clause is executed before really leaving the loop. 7.10. The continue statement ¶ continue_stmt : "continue" continue may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop. It continues with the next cycle of the nearest enclosing loop. When continue passes control out of a try statement with a finally clause, that finally clause is executed before really starting the next loop cycle. 7.11. The import statement ¶ import_stmt : "import" module [ "as" identifier ] ( "," module [ "as" identifier ])* | "from" relative_module "import" identifier [ "as" identifier ] ( "," identifier [ "as" identifier ])* | "from" relative_module "import" "(" identifier [ "as" identifier ] ( "," identifier [ "as" identifier ])* [ "," ] ")" | "from" relative_module "import" "*" module : ( identifier "." )* identifier relative_module : "." * module | "." + The basic import statement (no from clause) is executed in two steps: find a module, loading and initializing it if necessary define a name or names in the local namespace for the scope where the import statement occurs. When the statement contains multiple clauses (separated by commas) the two steps are carried out separately for each clause, just as though the clauses had been separated out into individual import statements. The details of the first step, finding and loading modules, are described in greater detail in the section on the import system , which also describes the various types of packages and modules that can be imported, as well as all the hooks that can be used to customize the import system. Note that failures in this step may indicate either that the module could not be located, or that an error occurred while initializing the module, which includes execution of the module’s code. If the requested module is retrieved successfully, it will be made available in the local namespace in one of three ways: If the module name is followed by as , then the name following as is bound directly to the imported module. If no other name is specified, and the module being imported is a top level module, the module’s name is bound in the local namespace as a reference to the imported module If the module being imported is not a top level module, then the name of the top level package that contains the module is bound in the local namespace as a reference to the top level package. The imported module must be accessed using its full qualified name rather than directly The from form uses a slightly more complex process: find the module specified in the from clause, loading and initializing it if necessary; for each of the identifiers specified in the import clauses: check if the imported module has an attribute by that name if not, attempt to import a submodule with that name and then check the imported module again for that attribute if the attribute is not found, ImportError is raised. otherwise, a reference to that value is stored in the local namespace, using the name in the as clause if it is present, otherwise using the attribute name Examples: import foo # foo imported and bound locally import foo.bar.baz # foo, foo.bar, and foo.bar.baz imported, foo bound locally import foo.bar.baz as fbb # foo, foo.bar, and foo.bar.baz imported, foo.bar.baz bound as fbb from foo.bar import baz # foo, foo.bar, and foo.bar.baz imported, foo.bar.baz bound as baz from foo import attr # foo imported and foo.attr bound as attr If the list of identifiers is replaced by a star ( '*' ), all public names defined in the module are bound in the local namespace for the scope where the import statement occurs. The public names defined by a module are determined by checking the module’s namespace for a variable named __all__ ; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ( '_' ). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module). The wild card form of import — from module import * — is only allowed at the module level. Attempting to use it in class or function definitions will raise a SyntaxError . When specifying what module to import you do not have to specify the absolute name of the module. When a module or package is contained within another package it is possible to make a relative import within the same top package without having to mention the package name. By using leading dots in the specified module or package after from you can specify how high to traverse up the current package hierarchy without specifying exact names. One leading dot means the current package where the module making the import exists. Two dots means up one package level. Three dots is up two levels, etc. So if you execute from . import mod from a module in the pkg package then you will end up importing pkg.mod . If you execute from ..subpkg2 import mod from within pkg.subpkg1 you will import pkg.subpkg2.mod . The specification for relative imports is contained in the Package Relative Imports section. importlib.import_module() is provided to support applications that determine dynamically the modules to be loaded. Raises an auditing event import with arguments module , filename , sys.path , sys.meta_path , sys.path_hooks . 7.11.1. Future statements ¶ A future statement is a directive to the compiler that a particular module should be compiled using syntax or semantics that will be available in a specified future release of Python where the feature becomes standard. The future statement is intended to ease migration to future versions of Python that introduce incompatible changes to the language. It allows use of the new features on a per-module basis before the release in which the feature becomes standard. future_stmt : "from" "__future__" "import" feature [ "as" identifier ] ( "," feature [ "as" identifier ])* | "from" "__future__" "import" "(" feature [ "as" identifier ] ( "," feature [ "as" identifier ])* [ "," ] ")" feature : identifier A future statement must appear near the top of the module. The only lines that can appear before a future statement are: the module docstring (if any), comments, blank lines, and other future statements. The only feature that requires using the future statement is annotations (see PEP 563 ). All historical features enabled by the future statement are still recognized by Python 3. The list includes absolute_import , division , generators , generator_stop , unicode_literals , print_function , nested_scopes and with_statement . They are all redundant because they are always enabled, and only kept for backwards compatibility. A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime. For any given release, the compiler knows which feature names have been defined, and raises a compile-time error if a future statement contains a feature not known to it. The direct runtime semantics are the same as for any import statement: there is a standard module __future__ , described later, and it will be imported in the usual way at the time the future statement is executed. The interesting runtime semantics depend on the specific feature enabled by the future statement. Note that there is nothing special about the statement: import __future__ [ as name ] That is not a future statement; it’s an ordinary import statement with no special semantics or syntax restrictions. Code compiled by calls to the built-in functions exec() and compile() that occur in a module M containing a future statement will, by default, use the new syntax or semantics associated with the future statement. This can be controlled by optional arguments to compile() — see the documentation of that function for details. A future statement typed at an interactive interpreter prompt will take effect for the rest of the interpreter session. If an interpreter is started with the -i option, is passed a script name to execute, and the script includes a future statement, it will be in effect in the interactive session started after the script is executed. See also PEP 236 - Back to the __future__ The original proposal for the __future__ mechanism. 7.12. The global statement ¶ global_stmt : "global" identifier ( "," identifier )* The global statement causes the listed identifiers to be interpreted as globals. It would be impossible to assign to a global variable without global , although free variables may refer to globals without being declared global. The global statement applies to the entire current scope (module, function body or class definition). A SyntaxError is raised if a variable is used or assigned to prior to its global declaration in the scope. At the module level, all variables are global, so a global statement has no effect. However, variables must still not be used or assigned to prior to their global declaration. This requirement is relaxed in the interactive prompt ( REPL ). Programmer’s note: global is a directive to the parser. It applies only to code parsed at the same time as the global statement. In particular, a global statement contained in a string or code object supplied to the built-in exec() function does not affect the code block containing the function call, and code contained in such a string is unaffected by global statements in the code containing the function call. The same applies to the eval() and compile() functions. 7.13. The nonlocal statement ¶ nonlocal_stmt : "nonlocal" identifier ( "," identifier )* When the definition of a function or class is nested (enclosed) within the definitions of other functions, its nonlocal scopes are the local scopes of the enclosing functions. The nonlocal statement causes the listed identifiers to refer to names previously bound in nonlocal scopes. It allows encapsulated code to rebind such nonlocal identifiers. If a name is bound in more than one nonlocal scope, the nearest binding is used. If a name is not bound in any nonlocal scope, or if there is no nonlocal scope, a SyntaxError is raised. The nonlocal statement applies to the entire scope of a function or class body. A SyntaxError is raised if a variable is used or assigned to prior to its nonlocal declaration in the scope. See also PEP 3104 - Access to Names in Outer Scopes The specification for the nonlocal statement. Programmer’s note: nonlocal is a directive to the parser and applies only to code parsed along with it. See the note for the global statement. 7.14. The type statement ¶ type_stmt : 'type' identifier [ type_params ] "=" expression The type statement declares a type alias, which is an instance of typing.TypeAliasType . For example, the following statement creates a type alias: type Point = tuple [ float , float ] This code is roughly equivalent to: annotation - def VALUE_OF_Point (): return tuple [ float , float ] Point = typing . TypeAliasType ( "Point" , VALUE_OF_Point ()) annotation-def indicates an annotation scope , which behaves mostly like a function, but with several small differences. The value of the type alias is evaluated in the annotation scope. It is not evaluated when the type alias is created, but only when the value is accessed through the type alias’s __value__ attribute (see Lazy evaluation ). This allows the type alias to refer to names that are not yet defined. Type aliases may be made generic by adding a type parameter list after the name. See Generic type aliases for more. type is a soft keyword . Added in version 3.12. See also PEP 695 - Type Parameter Syntax Introduced the type statement and syntax for generic classes and functions.

Cijene usluga koje se plaćaju, uključujući ponavljajuće naknade za pretplatu, podložne su povremenim promjenama iz razloga koji obuhvaćaju poslovne, financijske ili pravne razloge. X će u razumnom roku unaprijed objaviti obavijest o svakoj bitnoj promjeni cijene usluga koje se plaćaju. Za pretplatne usluge promjene cijena stupaju na snagu s početkom sljedećeg pretplatnog razdoblja nakon datuma promjene cijene. Ako se ne slažete s promjenom cijene, imate pravo odbiti promjenu otkazivanjem pretplate na odgovarajuću uslugu koja se plaća prije nego što promjena cijene stupi na snagu. Uvjeti plaćanja .  X nudi razne opcije plaćanja, koje mogu varirati ovisno o usluzi koja se plaća, vašem uređaju i/ili operacijskom sustavu, vašoj geografskoj lokaciji ili drugim čimbenicima. U dostupnoj mjeri (budući da X može povremeno učiniti dostupnima različite načine kupnje) te opcije plaćanja mogu obuhvaćati ​​mogućnost korištenja funkcije „plaćanja u aplikaciji” koju nude Google ili Apple, kao i plaćanja putem weba i treće strane koja djeluje u svojstvu X-ovog voditelja obrade plaćanja, servisa Stripe ( www.stripe.com; u nastavku teksta „ Stripe ”). Kada izvršite plaćanje, izričito pristajete: (i) platiti cijenu navedenu za tu uslugu koja se plaća, zajedno sa svim dodatnim iznosima primjenjivih poreza, naknada za upotrebu kreditnih kartica, bankovnih naknada, naknada za inozemne transakcije, mjenjačkih naknada i valutnih fluktuacija; i (ii) pridržavati se svih relevantnih uvjeta pružanja usluge, pravila o privatnosti ili drugih pravnih ugovora ili ograničenja (uključujući dodatna dobna ograničenja) koja propisuju Google, Apple ili Stripe (kao treće strane koje djeluju u svojstvu X-ovih voditelja obrade plaćanja) u vezi s vašim korištenjem određenog načina plaćanja (samo za potrebe primjera, ako odaberete plaćanje putem Appleove funkcije kupnje u aplikaciji, pristajete pridržavati se svih relevantnih uvjeta, zahtjeva i/ili ograničenja koje propisuje Apple). Svi privatni osobni podaci koje navedete u vezi s korištenjem usluga koje se plaćaju, uključujući, među ostalim, sve podatke navedene u vezi s plaćanjem, obrađivat će se u skladu s X-ovim pravilima o privatnosti. X može podijeliti vaše podatke za plaćanje s pružateljima usluga plaćanja radi obrade plaćanja, sprječavanja, otkrivanja i istraživanja prijevara ili drugih zabranjenih aktivnosti, olakšavanja rješavanja sporova poput storniranja ili povrata novca te u druge svrhe povezane s prihvaćanjem kreditnih i debitnih kartica ili ACH-a. Sami ste dužni pobrinuti se da vaši bankovni podaci, podaci o kreditnoj ili debitnoj kartici i/ili drugi podaci za plaćanje u svakom trenutku budu ažurni, potpuni i točni. Ako izvršite uplatu za uslugu koja se plaća, možda ćemo primiti informacije o vašoj transakciji, kao što su vrijeme izvršenja, datum isteka ili automatskog obnavljanja pretplate, platforma na kojoj ste izvršili kupnju i drugi podaci. X ne snosi odgovornost ni za kakve pogreške ili kašnjenja koje prouzroče voditelj plaćanja, Appleova trgovina App Store ili Google Play Store, vaša banka, tvrtka koja vam je izdala kreditnu karticu i/ili bilo koja platna mreža.

Primjena i raskid ugovora s korisnikom X-a, nepostojanje mogućnosti povrata novca, veći broj računa za X i ograničenja 1. Vezani ste ugovorom s korisnikom X-a . UVIJEK MORATE POŠTIVATI UGOVOR S KORISNIKOM X-a I PRIDRŽAVATI GA SE. Ugovor s korisnikom X-a uvijek se primjenjuje na vašu upotrebu usluge X, uključujući usluge i značajke koje se plaćaju. Ako ne budete poštivali ugovor s korisnikom X-a ili ga se ne budete pridržavali, odnosno ako X bude smatrao da ga niste poštivali ili ga se pridržavali, to može dovesti do otkazivanja vaših usluga koje se plaćaju. Svako takvo otkazivanje nadovezivat će se, bez ograničenja, na sve radnje koje X može poduzeti protiv vas u skladu s ugovorom s korisnikom X-a. U takvim slučajevima možete izgubiti pogodnosti svojih usluga koje se plaćaju te nećete imati pravo na povrat bilo kojeg iznosa koji ste platili (ili unaprijed platili) za usluge koje se plaćaju. 2. Zbog čega X može ukinuti vaš pristup uslugama koje se plaćaju. X može obustaviti ili ukinuti vaš pristup uslugama koje se plaćaju ili prestati pružati vam sve usluge koje se plaćaju ili dio tih usluga ili poduzeti bilo koju drugu radnju koju smatra prikladnom, uključujući obustavu vašeg računa (bez ikakve odgovornosti) u bilo kojem trenutku i zbog bilo kojeg razloga ili bez razloga, uključujući, među ostalim, bilo koji od sljedećih razloga: a. X smatra, prema isključivo vlastitu nahođenju, da ste prekršili ove uvjete ili da bi vaša upotreba usluga koje se plaćaju prekršila neki zakon. b. Takvo postupanje od X-a traži ili mu ga nalaže neki nadležni sud, regulatorno tijelo ili agencija za provođenje zakona. c. X ima neočekivanih tehničkih ili sigurnosnih problema. d. X vjeruje, prema vlastitom nahođenju, da ste prekršili X Korisnički ugovor; e. X vjeruje, prema vlastitom nahođenju, da sudjelujete u manipulaciji ili drugom ometajućem ili zabranjenom ponašanju općenito ili u vezi s plaćenim uslugama; f.  Stvarate rizik ili moguću pravnu izloženost za X; g. Vaš se račun treba ukloniti zbog nezakonitog postupanja. h. Vaš se račun treba ukloniti zbog produljene neaktivnosti, ili i. Naše pružanje plaćenih usluga (u cijelosti ili djelomično) više nije komercijalno održivo (prema vlastitom nahođenju X-a). 3. Sve su transakcije konačne. Sva plaćanja usluga koje se plaćaju konačna su te ne omogućuju povrat novca ili zamjenu, osim u skladu s mjerodavnim pravom. Ne jamčimo prirodu, kvalitetu ni vrijednost usluge koja se plaća ili njezinu dostupnost ili ponudu. Ni za koju neiskorištenu ili djelomično iskorištenu uslugu koja se plaća (na primjer, za djelomično iskorišteno pretplatno razdoblje) ne nude se povrati novca ili krediti.  4. Usluge koje se plaćaju nisu prenosive između računa za X. Svaka kupnja usluge koja se plaća odnosi se samo na jedan račun za X, što znači da će se vaša kupnja odnositi isključivo na račun koji ste koristili kada ste kupili uslugu koja se plaća te se neće odnositi ​​na druge račune kojima možda možete pristupati ili nad kojima imate kontrolu. Ako imate ili kontrolirate više računa i želite pristup uslugama koje se plaćaju putem svakog od računa, morate kupiti uslugu koja se plaća ponaosob za svaki račun. 5. Ograničenja i obveze.  a. Uslugu koja se plaća možete kupiti i koristiti samo ako vam zakoni u vašoj državi to dopuštaju i ako živite u državi koju X podržava za pripadnu uslugu koja se plaća. X može, prema vlastitom nahođenju, u određenim državama ograničiti mogućnost pristupa ili kupnje usluge koja se plaća. X zadržava pravo povremene izmjene popisa podržanih država. b. Zadržavamo pravo odbijanja transakcija za usluge koje se plaćaju ili otkazivanja ili ukidanja prodaje ili korištenja usluga koje se plaćaju prema isključivo vlastitu nahođenju.  c.  Ne smijete dopustiti drugima da vaš račun za X koriste za pristupanje bilo kojoj usluzi koja se plaća, a koju ta osoba nije naručila. d. Ne smijete kupiti ili koristiti uslugu koja se plaća ako ste osoba s kojom osobama iz SAD-a nije dopušteno poslovati zbog ekonomskih sankcija, uključujući, među ostalim, sankcije koje provodi Ured za kontrolu strane imovine u okviru Ministarstva financija Sjedinjenih Država ili bilo koje drugo primjenjivo sankcijsko tijelo („ zabranjena osoba ”). To, među ostalim, uključuje osobe koje se nalaze u sljedećim državama i regijama ili ondje imaju prebivalište: Kuba, Iran, ukrajinske regije Krima, Sjeverna Koreja i Sirija. Izjavljujete i jamčite da niste zabranjena osoba. e. IZJAVLJUJETE DA ĆETE USLUGE KOJE SE PLAĆAJU KORISTITI SAMO U ZAKONITE SVRHE I SAMO U SKLADU S UVJETIMA. Porezi i naknade . Sami snosite odgovornost za sve primjenjive poreze, davanja, carine i naknade povezane s kupnjom usluga koje se plaćaju, uključujući one koje treba platiti X-u ili trećoj strani koja obrađuje plaćanja, i pristajete ih platiti. Ti porezi mogu, među ostalim, obuhvaćati PDV, GST, porez na promet, porez po odbitku i sve druge primjenjive poreze. Ovisno o vašoj lokaciji, X može biti zadužen za prikupljanje i prijavljivanje informacija povezanih s porezima na transakcije koji proizlaze iz vaše kupnje usluga koje se plaćaju. X-u dajete dopuštenje za davanje informacija o vašem računu i vaših osobnih podataka relevantnim poreznim tijelima radi ispunjavanja naših obaveza povezanih s prikupljanjem poreza i poreznim izvješćivanjem.   Opći uvjeti 1.

Promjene odredbi.  X može povremeno revidirati ove Uvjete pružanja usluge kupcu X-ovih usluga na temelju valjane i razumne osnove. Valjana i razumna osnova može uključivati (i) promjenu naših usluga, na primjer zbog tehničkog, sigurnosnog ili operativnog događaja, (ii) otklanjanje tehničkih pogrešaka, (iii) promjenu našeg poslovanja, na primjer zbog promjena pravila, financijskih ili drugih smjernica, (iv) promjenu pravne situacije, na primjer zbog promjene zakona, zahtjeva službenog tijela ili odluke suda i (v) optimizaciju korisničkog iskustva kroz implementaciju novih značajki. Promjene neće biti retroaktivne, a vašu upotrebu usluga koje se plaćaju i sve pripadne transakcije regulirat će najnovija verzija uvjeta pružanja usluge kupcu X-ovih usluga, dostupna na adresi legal.x.com/purchaser-terms . Ako izmijenimo ili revidiramo ove Uvjete nakon što ste na njih pristali (na primjer, ako se ovi uvjeti izmijene nakon što ste kupili pretplatu), obvezujemo se obavijestiti vas do 30 dana (ovisno o konkretnim promjenama) prije stupanja na snagu materijalnih izmjena ovih uvjeta, istovremeno postavljajući razuman rok za korisnika u vezi s promjenama i obavještavajući vas o posljedicama daljnjeg korištenja nakon isteka roka. Takva se obavijest može dostaviti elektroničkim putem, uključujući (među ostalim) obavijest u okviru usluge ili e-poštu poslanu na adresu e-pošte povezanu s vašim računom. U slučaju da nastavite koristiti Plaćene usluge nakon isteka gore navedenog roka, slažete se da ćete biti vezani revidiranim X Uvjetima pružanja usluge kupca.

Uvjeti pružanja usluge kupcu X-ovih usluga napisani su na engleskom, ali su dostupni njihovi prijevodi na više jezika. X nastoji da prijevodi budu što točniji i vjerniji izvornoj engleskoj verziji. Međutim, u slučaju bilo kakvih odstupanja ili nedosljednosti, prednost imaju uvjeti pružanja usluge kupcu X-ovih usluga na engleskom jeziku. Prihvaćate da engleski bude referentni jezik za tumačenje i konstruiranje uvjeta pružanja usluge kupcu X-ovih usluga. 2. Promjene plaćenih usluga.  Naše plaćene usluge i naši proizvodi i usluge neprestano se razvijaju. X može promijeniti plaćene usluge na razumnoj i valjanoj osnovi. Takva valjana i razumna osnova može uključivati (i) tehnički, sigurnosni ili operativni razvoj, (ii) otklanjanje tehničkih pogrešaka, (iii) usklađenost s promijenjenom pravnom situacijom, primjerice zbog promjene zakona, zahtjeva službene agencije ili odluke suda, (iv) optimizaciju korisničkog iskustva kroz implementaciju novih značajki, i (v) promjena u našem poslovanju, na primjer zbog politike, financijskih okolnosti ili drugih promjena smjera. Obavijestit ćemo vas o svim promjenama plaćenih usluga do 30 dana prije nego što stupe na snagu, na primjer putem obavijesti o usluzi ili e-pošte poslane na adresu e-pošte povezanu s vašim računom, navodeći karakteristike i datum stupanja na snagu promjena te vas obavještavajući o vašem eventualnom pravu na raskid pretplate. Rok se može skratiti u slučaju promjena povezanih sa sigurnošću. Sljedeće se neće smatrati promjenama usluga koje se plaćaju u okviru ove odredbe: (i) promjene koje utječu na osnovnu prirodu usluga koje se plaćaju i bitne karakteristike usluge koju pruža X i (ii) trajni prekid pružanja usluga. X ne snosi odgovornost prema vama zbog bilo kakvih izmjena, obustavljanja ili ukidanja usluga koje se plaćaju. Kad je to zakonski propisano, prethodno navedeno ograničenje odgovornosti neće se primjenjivati na (i) naknadu predvidive štete u slučajevima donekle zanemarive povrede obveza, u mjeri u kojoj je njihovo ispunjenje nužno za pravilno izvršenje ugovora i korisnici se mogu osloniti na njihovo ispunjenje (bitne ugovorne obveze), od strane platforme X ili njezinih zakonskih zastupnika ili posrednika, i (ii) odgovornost platforme X za (a) štetu nastalu povredom života, tijela ili zdravlja, kao i za štetu prouzročenu namjernom ili grubom nepažnjom platforme X, njezinih zakonskih zastupnika ili posrednika te (b) štetu zbog nepoštivanja jamstva ili zajamčenih karakteristika ili kao rezultat prijevarno skrivenog nedostatka. Posebni uvjeti i odredbe (uključeni u nastavku) za određenu plaćenu uslugu određuju kako možete otkazati pretplatu ili, ako je primjenjivo, zatražiti povrat novca.  3. Promjene cijena. Cijene plaćenih usluga, uključujući ponavljajuće pretplatničke naknade, podložne su promjenama s vremena na vrijeme zbog promjene troškova koji se odnose na rad, održavanje, tehničku opskrbu, poslovna razmatranja i naknade koje naplaćuju treće strane ili zakonske naknade, prema našem razumnom nahođenju. U slučaju povećanja troškova, X zadržava pravo prilagodbe cijena usluga uz naplatu. X će vas obavijestiti o svim promjenama cijena u pisanom obliku do 30 dana prije nego što stupe na snagu, na primjer putem obavijesti o usluzi ili e-poštom na adresu e-pošte povezanu s vašim računom, navodeći svoja prava i posljedice njihovog neostvarivanja. U slučaju promjene cijene, možete raskinuti pretplatu na primjenjivu plaćenu uslugu ili korisnički ugovor do 24 sata prije početka sljedećeg ciklusa naplate, pod uvjetom da se otkazivanje izvrši u roku od 30 dana od primitka obavijesti. U suprotnom, promjena cijene stupit će na snagu u vrijeme navedeno u obavijesti. Za pretplatničke usluge promjene cijena stupit će na snagu na početku sljedećeg pretplatničkog razdoblja nakon datuma stupanja na snagu promjene cijene.  Uvjeti plaćanja .  X nudi razne opcije plaćanja, koje mogu varirati ovisno o usluzi koja se plaća, vašem uređaju i/ili operacijskom sustavu, vašoj geografskoj lokaciji ili drugim čimbenicima. U dostupnoj mjeri (budući da X može povremeno učiniti dostupnima različite načine kupnje) te opcije plaćanja mogu obuhvaćati ​​mogućnost korištenja funkcije „plaćanja u aplikaciji” koju nude Google ili Apple, kao i plaćanja putem weba i treće strane koja djeluje u svojstvu X-ovog voditelja obrade plaćanja, servisa Stripe ( www.stripe.com; u nastavku teksta „ Stripe ”). Kada izvršite plaćanje, izričito pristajete: (i) platiti cijenu navedenu za tu uslugu koja se plaća, zajedno sa svim dodatnim iznosima primjenjivih poreza, naknada za upotrebu kreditnih kartica, bankovnih naknada, naknada za inozemne transakcije, mjenjačkih naknada i valutnih fluktuacija; i (ii) pridržavati se svih relevantnih uvjeta pružanja usluge, pravila o privatnosti ili drugih pravnih ugovora ili ograničenja (uključujući dodatna dobna ograničenja) koja propisuju Google, Apple ili Stripe (kao treće strane koje djeluju u svojstvu X-ovih voditelja obrade plaćanja) u vezi s vašim korištenjem određenog načina plaćanja (samo za potrebe primjera, ako odaberete plaćanje putem Appleove funkcije kupnje u aplikaciji, pristajete pridržavati se svih relevantnih uvjeta, zahtjeva i/ili ograničenja koje propisuje Apple). Svi privatni osobni podaci koje navedete u vezi s korištenjem usluga koje se plaćaju, uključujući, među ostalim, sve podatke navedene u vezi s plaćanjem, obrađivat će se u skladu s X-ovim pravilima o privatnosti. X može podijeliti vaše podatke za plaćanje s pružateljima usluga plaćanja radi obrade plaćanja, sprječavanja, otkrivanja i istraživanja prijevara ili drugih zabranjenih aktivnosti, olakšavanja rješavanja sporova poput storniranja ili povrata novca te u druge svrhe povezane s prihvaćanjem kreditnih i debitnih kartica ili ACH-a. Sami ste dužni pobrinuti se da vaši bankovni podaci, podaci o kreditnoj ili debitnoj kartici i/ili drugi podaci za plaćanje u svakom trenutku budu ažurni, potpuni i točni. Ako izvršite uplatu za uslugu koja se plaća, možda ćemo primiti informacije o vašoj transakciji, kao što su vrijeme izvršenja, datum isteka ili automatskog obnavljanja pretplate, platforma na kojoj ste izvršili kupnju i drugi podaci. X ne snosi odgovornost ni za kakve pogreške ili kašnjenja koje prouzroče voditelj plaćanja, Appleova trgovina App Store ili Google Play Store, vaša banka, tvrtka koja vam je izdala kreditnu karticu i/ili bilo koja platna mreža. Uvjete plaćanja koji se primjenjuju na određenu uslugu koja se plaća, uključujući način postupanja s obnovama pretplate i druge važne uvjete, potražite u nastavku u pripadnim uvjetima i odredbama za tu uslugu koja se plaća. Primjena i raskid ugovora s korisnikom X-a, nepostojanje mogućnosti povrata novca, veći broj računa za X i ograničenja 1. Vezani ste ugovorom s korisnikom X-a . UVIJEK MORATE POŠTIVATI UGOVOR S KORISNIKOM X-a I PRIDRŽAVATI GA SE. Ugovor s korisnikom X-a uvijek se primjenjuje na vašu upotrebu usluge X, uključujući usluge i značajke koje se plaćaju. Ako ne budete poštivali ugovor s korisnikom X-a ili ga se ne budete pridržavali, odnosno ako X bude smatrao da ga niste poštivali ili ga se pridržavali, to može dovesti do otkazivanja vaših usluga koje se plaćaju. Svako takvo otkazivanje nadovezivat će se, bez ograničenja, na sve radnje koje X može poduzeti protiv vas u skladu s ugovorom s korisnikom X-a. U takvim slučajevima možete izgubiti pogodnosti svojih usluga koje se plaćaju te nećete imati pravo na povrat bilo kojeg iznosa koji ste platili (ili unaprijed platili) za usluge koje se plaćaju. 2. Zbog čega X može ukinuti vaš pristup uslugama koje se plaćaju. X može obustaviti ili ukinuti vaš pristup uslugama koje se plaćaju ili prestati pružati vam sve usluge koje se plaćaju ili dio tih usluga ili poduzeti bilo koju drugu radnju koju smatra prikladnom, uključujući obustavu vašeg računa (bez ikakve odgovornosti) u bilo kojem trenutku i zbog bilo kojeg razloga ili bez razloga, uključujući, među ostalim, bilo koji od sljedećih razumnih temelja: a. X smatra, prema isključivo vlastitu nahođenju, da ste prekršili ove uvjete ili da bi vaša upotreba usluga koje se plaćaju prekršila neki zakon. b. Takvo postupanje od X-a traži ili mu ga nalaže neki nadležni sud, regulatorno tijelo ili agencija za provođenje zakona. c. X ima neočekivanih tehničkih ili sigurnosnih problema. d. X vjeruje, prema vlastitom razumnom nahođenju, da ste prekršili X korisnički ugovor; e. X vjeruje iz valjanih razloga, kao što je ako sudjelujete u manipulaciji, igranju ili drugom ometajućem ili zabranjenom ponašanju u vezi s plaćenim uslugama; f.  Stvarate rizik ili moguću pravnu izloženost za X; g. Vaš se račun treba ukloniti zbog nezakonitog postupanja. h. Vaš se račun treba ukloniti zbog produljene neaktivnosti, ili i. Naše pružanje plaćenih usluga (u cijelosti ili djelomično) više nije komercijalno održivo (prema vlastitom nahođenju X-a). 3. Sve su transakcije konačne. Sva plaćanja usluga koje se plaćaju konačna su te ne omogućuju povrat novca ili zamjenu, osim u skladu s mjerodavnim pravom. Ne jamčimo prirodu, kvalitetu ni vrijednost usluge koja se plaća ili njezinu dostupnost ili ponudu. Ni za koju neiskorištenu ili djelomično iskorištenu uslugu koja se plaća (na primjer, za djelomično iskorišteno pretplatno razdoblje) ne nude se povrati novca ili krediti.  4. Usluge koje se plaćaju nisu prenosive između računa za X. Svaka kupnja usluge koja se plaća odnosi se samo na jedan račun za X, što znači da će se vaša kupnja odnositi isključivo na račun koji ste koristili kada ste kupili uslugu koja se plaća te se neće odnositi ​​na druge račune kojima možda možete pristupati ili nad kojima imate kontrolu. Ako imate ili kontrolirate više računa i želite pristup uslugama koje se plaćaju putem svakog od računa, morate kupiti uslugu koja se plaća ponaosob za svaki račun. 5. Ograničenja i obveze.  a. Uslugu koja se plaća možete kupiti i koristiti samo ako vam zakoni u vašoj državi to dopuštaju i ako živite u državi koju X podržava za pripadnu uslugu koja se plaća. X može, prema vlastitom nahođenju, u određenim državama ograničiti mogućnost pristupa ili kupnje usluge koja se plaća. X zadržava pravo povremene izmjene popisa podržanih država. b. Zadržavamo pravo odbijanja transakcija za usluge koje se plaćaju ili otkazivanja ili ukidanja prodaje ili korištenja usluga koje se plaćaju prema isključivo vlastitu nahođenju.  c.  Ne smijete dopustiti drugima da vaš račun za X koriste za pristupanje bilo kojoj usluzi koja se plaća, a koju ta osoba nije naručila. d. Ne smijete kupiti ili koristiti uslugu koja se plaća ako ste osoba s kojom osobama iz SAD-a nije dopušteno poslovati zbog ekonomskih sankcija, uključujući, među ostalim, sankcije koje provodi Ured za kontrolu strane imovine u okviru Ministarstva financija Sjedinjenih Država ili bilo koje drugo primjenjivo sankcijsko tijelo („ zabranjena osoba ”). To, među ostalim, uključuje osobe koje se nalaze u sljedećim državama i regijama ili ondje imaju prebivalište: Kuba, Iran, ukrajinske regije Krima, Sjeverna Koreja i Sirija. Izjavljujete i jamčite da niste zabranjena osoba. e. IZJAVLJUJETE DA ĆETE USLUGE KOJE SE PLAĆAJU KORISTITI SAMO U ZAKONITE SVRHE I SAMO U SKLADU S UVJETIMA. Porezi i naknade . Sami snosite odgovornost za sve primjenjive poreze, davanja, carine i naknade povezane s kupnjom usluga koje se plaćaju, uključujući one koje treba platiti X-u ili trećoj strani koja obrađuje plaćanja, i pristajete ih platiti. Ti porezi mogu, među ostalim, obuhvaćati PDV, GST, porez na promet, porez po odbitku i sve druge primjenjive poreze. Ovisno o vašoj lokaciji, X može biti zadužen za prikupljanje i prijavljivanje informacija povezanih s porezima na transakcije koji proizlaze iz vaše kupnje usluga koje se plaćaju. X-u dajete dopuštenje za davanje informacija o vašem računu i vaših osobnih podataka relevantnim poreznim tijelima radi ispunjavanja naših obaveza povezanih s prikupljanjem poreza i poreznim izvješćivanjem. Opći uvjeti 1. Podaci za kontakt. Ako imate pitanja o uslugama koje se plaćaju ili ovim uvjetima, dodatne pojedinosti možete potražiti u X-ovu centru za pomoć za usluge koje se plaćaju . Ako ste već kupili uslugu koja se plaća, možete nas kontaktirati i putem veze za podršku, koja je dostupna u navigacijskom izborniku vašeg računa za X pod postavkama plaćanja ili pretplate. Ako imate dodatnih pitanja, možete nam se obratiti ovdje putem obrasca „Pomoć za značajke koje se plaćaju”. 2. ODRICANJA OD ODGOVORNOSTI. U NAJVEĆOJ MJERI DOPUŠTENOJ MJERODAVNIM PRAVOM USLUGAMA KOJE SE PLAĆAJU PRISTUPATE I KORISTITE IH NA VLASTITU ODGOVORNOST. RAZUMIJETE I PRISTAJETE DA VAM SE USLUGE KOJE SE PLAĆAJU PRUŽAJU „KAKVE JESU” I „KAKO BUDU DOSTUPNE”. X SE ODRIČE SVIH JAMSTAVA I UVJETA, BILO IZRIČITIH ILI PODRAZUMIJEVANIH, POVEZANIH S PRIKLADNOSTI ZA PRODAJU, PRIMJERENOSTI ODREĐENOJ NAMJENI ILI NEPOSTOJANJEM KRŠENJA TUĐIH PRAVA. X NE DAJE NIKAKVO JAMSTVO NI IZJAVU TE SE ODRIČE BILO KAKVE ODGOVORNOSTI I OBAVEZE VEZANE UZ: (I) POTPUNOST, TOČNOST, DOSTUPNOST, PRAVOVREMENOST, SIGURNOST ILI POUZDANOST USLUGA KOJE SE PLAĆAJU I (II) UDOVOLJAVANJE USLUGA KOJE SE PLAĆAJU VAŠIM ZAHTJEVIMA ILI NJIHOVU DOSTUPNOST KOJA BI BILA NEPREKIDNA, SIGURNA I LIŠENA POGREŠAKA. SAMI STE ODGOVORNI ZA KORIŠTENJE USLUGE X, UKLJUČUJUĆI USLUGE KOJE SE PLAĆAJU, I SVEG SADRŽAJA KOJI IZRADITE. 3. OGRANIČENJE ODGOVORNOSTI. U NAJVEĆOJ MJERI DOPUŠTENOJ MJERODAVNIM PRAVOM SUBJEKTI PLATFORME X NE SNOSE ODGOVORNOST NI ZA KAKVU NEIZRAVNU, SLUČAJNU, POSEBNU, POSLJEDIČNU ILI KAZNENU ŠTETU I NI ZA KAKAV GUBITAK DOBITI ILI PRIHODA, BILO DA JE NASTAO IZRAVNO ILI NEIZRAVNO, TE NI ZA KAKAV GUBITAK PODATAKA, UPOTREBE, REPUTACIJE ILI DRUGI NEMATERIJALNI GUBITAK PROIZAŠAO IZ (i) VAŠEG PRISTUPANJA USLUGAMA KOJE SE PLAĆAJU ILI NJIHOVE UPOTREBE ODNOSNO NEMOGUĆNOSTI PRISTUPANJA USLUGAMA KOJE SE PLAĆAJU ILI NJIHOVE UPOTREBE (ii) BILO KAKVOG POSTUPANJA ILI SADRŽAJA BILO KOJE TREĆE STRANE OBJAVLJENOG PUTEM USLUGA KOJE SE PLAĆAJU, UKLJUČUJUĆI, MEĐU OSTALIM, BILO KAKVO KLEVETNIČKO, UVREDLJIVO ILI NEZAKONITO POSTUPANJE DRUGIH KORISNIKA ILI TREĆIH STRANA (iii) BILO KAKVOG SADRŽAJA DOBIVENOG PUTEM USLUGA KOJE SE PLAĆAJU ILI (iv) NEOVLAŠTENOG PRISTUPA, UPOTREBE ILI IZMJENE VAŠIH PRIJENOSA ILI SADRŽAJA.

OGRANIČENJA OVOG PODODJELJKA PRIMJENJUJU SE NA SVE TEORIJE ODGOVORNOSTI, BILO TEMELJENE NA JAMSTVU, UGOVORU, STATUTU, DELIKTU (UKLJUČUJUĆI NEMAR) ILI DRUGOME, TE BEZ OBZIRA NA TO JESU LI SUBJEKTI PLATFORME X BILI OBAVIJEŠTENI O MOGUĆNOSTI TAKVE ŠTETE, ČAK I AKO SE ZA OVDJE NAVEDENI PRAVNI LIJEK UTVRDI DA NIJE POSLUŽIO SVOJOJ SUŠTINSKOJ SVRSI. „SUBJEKTI PLATFORME X-OVI” OBUHVAĆAJU X, NJEGOVA MATIČNA DRUŠTVA, PODRUŽNICE, POVEZANA DRUŠTVA, DUŽNOSNIKE, DIREKTORE, ZAPOSLENIKE, AGENTE, PREDSTAVNIKE, PARTNERE I DAVATELJE LICENCI.

Apprendre React Démarrage rapide Bienvenue dans la documentation React ! Dans cette page, vous allez découvrir les 80% de concepts React que vous utiliserez sans doute au quotidien. Vous allez apprendre Comment créer et imbriquer des composants Comment ajouter du balisage et des styles Comment afficher des données Comment faire un rendu conditionnel et traiter des listes Comment réagir à des événements et mettre à jour l’affichage Comment partager des données entre composants Créer et imbriquer des composants Les applis React sont constituées de composants . Un composant, c’est un bout d’UI ( User Interface , donc interface utilisateur) avec son comportement et son apparence propres. Un composant peut être aussi petit qu’un bouton, ou aussi grand qu’une page entière. Les composants React sont des fonctions JavaScript qui renvoient du balisage : function MyButton ( ) { return ( < button > Je suis un bouton </ button > ) ; } À présent que vous avez déclaré MyButton , vous pouvez l’imbriquer dans un autre composant : export default function MyApp ( ) { return ( < div > < h1 > Bienvenue dans mon appli </ h1 > < MyButton /> </ div > ) ; } Remarquez que <MyButton /> commence par une majuscule. C’est comme ça que React sait qu’il s’agit d’un composant. Les noms de composants React doivent toujours démarrer par une majuscule, alors que les balises HTML doivent être en minuscules. Voyons ce que ça donne : App.js App.js Réinitialiser Fork function MyButton ( ) { return ( < button > Je suis un bouton </ button > ) ; } export default function MyApp ( ) { return ( < div > < h1 > Bienvenue dans mon appli </ h1 > < MyButton /> </ div > ) ; } Voir plus Les mots-clés export default indiquent le composant principal du fichier. Si vous n’êtes pas habitué·e à certains éléments syntaxiques de JavaScript, le MDN et javascript.info sont d’excellentes références. Écrire du balisage avec JSX La syntaxe de balisage que vous avez vue ci-avant s’appelle JSX . Elle n’est pas à proprement parler obligatoire, mais la plupart des projets React utilisent JSX par confort. Tous les outils que nous recommandons pour le développement en local prennent en charge JSX d’entrée de jeu. JSX est plus exigeant que HTML. Vous devez fermer les balises telles que <br /> . Par ailleurs, votre composant ne peut pas renvoyer plusieurs balises JSX. Il vous faudrait les enrober dans un parent commun, tel qu’un <div>...</div> ou un Fragment <>...</> vide : function AboutPage ( ) { return ( < > < h1 > À propos </ h1 > < p > Bien le bonjour. < br /> Comment ça va ? </ p > </ > ) ; } Si vous avez beaucoup de HTML à migrer vers du JSX, vous pouvez vous aider d’un convertisseur en ligne . Ajouter des styles Dans React, vous précisez une classe CSS avec className . Ça fonctionne exactement comme l’attribut class en HTML : < img className = "avatar" /> Ensuite vous écrivez vos règles CSS dans un fichier CSS distinct : /* Dans votre CSS */ .avatar { border-radius : 50 % ; } React n’impose aucune façon particulière de fournir des fichiers CSS. Le cas le plus simple consiste à utiliser une balise <link> dans votre HTML. Si vous utilisez un outil de build ou un framework, consultez sa documentation pour apprendre comment ajouter un fichier CSS à votre projet. Afficher des données JSX vous permet de mettre du balisage dans du JavaScript. Les accolades servent à « ressortir » dans JavaScript afin d’injecter une variable ou expression dans votre code et de l’afficher à l’utilisateur. Par exemple, ce code affichera user.name  : return ( < h1 > { user . name } </ h1 > ) ; Vous pouvez aussi « ressortir dans JavaScript » au sein d’attributs JSX, mais vous devrez utiliser des accolades à la place des guillemets. Par exemple, className="avatar" passe la chaîne "avatar" comme classe CSS, mais src={user.imageUrl} lit d’abord la valeur de l’expression JavaScript user.imageUrl , et ensuite passe cette valeur à l’attribut src  : return ( < img className = "avatar" src = { user . imageUrl } /> ) ; Vous pouvez utiliser des expressions plus complexes au sein des accolades JSX, par exemple de la concaténation de chaînes  : App.js App.js Réinitialiser Fork const user = { name : 'Hedy Lamarr' , imageUrl : 'https://i.imgur.com/yXOvdOSs.jpg' , imageSize : 90 , } ; export default function Profile ( ) { return ( < > < h1 > { user . name } </ h1 > < img className = "avatar" src = { user . imageUrl } alt = { 'Photo de ' + user . name } style = { { width : user . imageSize , height : user . imageSize } } /> </ > ) ; } Voir plus Dans l’exemple ci-avant, style={{}} ne constitue pas une syntaxe spéciale : c’est un littéral objet {} au sein d’accolades JSX style={} . Vous pouvez utiliser l’attribut style lorsque vos styles dépendent de données dans votre code JavaScript. Affichage conditionnel Dans React, il n’y a pas de syntaxe spéciale pour écrire des conditions. Au lieu de ça, on utilise les mêmes techniques que pour écrire du code JavaScript normal. Par exemple, vous pouvez utiliser une instruction if pour choisir quel bout de JSX inclure : let content ; if ( isLoggedIn ) { content = < AdminPanel /> ; } else { content = < LoginForm /> ; } return ( < div > { content } </ div > ) ; Si vous préférez un style plus compact, vous pouvez utiliser l’ opérateur ternaire conditionnel ? . Contrairement à if , celui-ci marche aussi au sein-même de JSX : < div > { isLoggedIn ? ( < AdminPanel /> ) : ( < LoginForm /> ) } </ div > Si vous n’avez pas besoin de la branche else , vous pouvez utiliser l’ opérateur && logique , plus court : < div > { isLoggedIn && < AdminPanel /> } </ div > Toutes ces façons de faire fonctionnent aussi pour la définition conditionnelle d’attributs. Si certaines de ces syntaxes vous déroutent, vous pouvez toujours commencer par if...else . Afficher des listes Pour afficher des listes de composants vous utiliserez principalement la méthode map() des tableaux , et parfois des boucles for . Par exemple, disons que vous avez un tableau de produits : const products = [ { title : 'Chou' , id : 1 } , { title : 'Ail' , id : 2 } , { title : 'Pomme' , id : 3 } , ] ; Dans ce composant, on utilise la méthode map() pour transformer un tableau de produits en tableau d’éléments <li>  : const listItems = products . map ( product => < li key = { product . id } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; Remarquez que <li> a un attribut key . Pour chaque élément d’une liste, vous devriez passer une chaîne de caractères ou un numéro qui l’identifie de façon unique au sein de cette liste. En général, cette clé vient de vos données, par exemple une clé primaire dans la base de données. React utilise ces clés pour comprendre la nature de vos changements : insertion, suppression ou réordonnancement des éléments. App.js App.js Réinitialiser Fork const products = [ { title : 'Chou' , isFruit : false , id : 1 } , { title : 'Ail' , isFruit : false , id : 2 } , { title : 'Pomme' , isFruit : true , id : 3 } , ] ; export default function ShoppingList ( ) { const listItems = products . map ( product => < li key = { product . id } style = { { color : product . isFruit ? 'magenta' : 'darkgreen' } } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; } Voir plus Réagir à des événements Vous pouvez réagir à des événements en utilisant des gestionnaires d’événements dans vos composants : function MyButton ( ) { function handleClick ( ) { alert ( 'Vous avez cliqué !' ) ; } return ( < button onClick = { handleClick } > Cliquez ici </ button > ) ; } Remarquez que onClick={handleClick} n’a pas de parenthèses à la fin ! Prenez garde de ne pas appeler la fonction de gestion d’événement : vous avez seulement besoin de la transmettre . React appellera votre gestionnaire d’événement lorsque l’utilisateur activera le bouton. Mettre à jour l’affichage Le plus souvent, vous voudrez que votre composant « se souvienne » de certaines informations et les affiche. Par exemple, peut-être souhaitez-vous compter le nombre de fois qu’un bouton a été cliqué. Pour cela, il vous faut équiper votre composant d’un état . Commencez par importer useState depuis React : import { useState } from 'react' ; Servez-vous-en pour déclarer une variable d’état dans votre composant : function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; // ... Un appel à useState vous renvoie deux choses : l’état courant ( count ), et une fonction pour le mettre à jour ( setCount ). Vous pouvez leur donner n’importe quels noms, mais la convention largement répandue consiste à écrire [something, setSomething] . La première fois que le bouton est affiché, count est à 0 car vous avez passé 0 à useState() . Lorsque vous souhaitez modifier l’état, appelez setCount() et passez-lui la nouvelle valeur. Cliquer sur ce bouton incrémentera le compteur : function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Cliqué { count } fois </ button > ) ; } React appellera à nouveau la fonction de votre composant. Cette fois, count vaudra 1 . La fois suivante, ce sera 2 . Et ainsi de suite. Si vous affichez le même composant plusieurs fois, chacun a son propre état. Cliquez les différents boutons séparément : App.js App.js Réinitialiser Fork import { useState } from 'react' ; export default function MyApp ( ) { return ( < div > < h1 > Des compteurs indépendants </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Cliqué { count } fois </ button > ) ; } Voir plus Voyez comme chaque bouton « se souvient » de son propre état count et n’affecte pas les autres boutons. Utiliser des Hooks Les fonctions dont le nom commence par use sont appelées Hooks . useState est un Hook fourni directement par React. Vous pouvez trouver les autres Hooks fournis dans la référence de l’API . Vous pouvez aussi créer vos propres Hooks en combinant ceux existants. Les Hooks sont plus contraignants que les autres fonctions. Vous pouvez seulement appeler les Hooks au début du code vos composants (ou d’autres Hooks). Si vous voulez utiliser useState dans une condition ou une boucle, extrayez un composant dédié au besoin et mettez le Hook à l’intérieur. Partager des données entre composants Dans l’exemple précédent, chaque MyButton avait son propre count indépendant, et lorsqu’un bouton était cliqué, seul le count de ce bouton changeait : Au départ, l’état count de chaque MyButton est à 0 Le premier MyButton met à jour son état count à 1 Toutefois, vous aurez régulièrement besoin que vos composants partagent des données et se mettent à jour de façon synchronisée . Afin que les deux composants MyButton affichent le même count et se mettent à jour ensemble, vous allez devoir déplacer l’état depuis les boutons individuels « vers le haut », vers le plus proche composant qui les contienne tous. Dans cet exemple, il s’agit de MyApp  : Au départ, l’état count de MyApp vaut 0 , qui est transmis aux deux enfants Au clic, MyApp met à jour son état count à 1 , et le transmet aux deux enfants À présent quand vous cliquez l’un ou l’autre bouton, le count de MyApp change, ce qui altère les deux compteurs dans MyButton . Voici comment exprimer la même chose sous forme de code. Pour commencer, faites remonter l’état de MyButton vers MyApp  : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Des compteurs indépendants </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { // ... on a bougé ce code à partir d’ici ... } Ensuite, transmettez l’état vers le bas de MyApp à chaque MyButton , ainsi que le gestionnaire partagé de clics. Vous pouvez passer ces informations à MyButton au moyen d’accolades JSX, comme nous le faisions précédemment pour des balises natives comme <img>  : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Des compteurs synchronisés </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } Les informations ainsi transmises vers le bas s’appellent des props . Désormais, le composant MyApp contient l’état state et le gestionnaire d’événement handleClick , et passe ces deux informations comme props à chacun des boutons. Pour finir, modifiez MyButton pour lire les props que le composant parent lui a passées : function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Cliqué { count } fois </ button > ) ; } Lorsque vous cliquez un bouton, le gestionnaire onClick est déclenché. La prop onClick de chaque bouton utilise la fonction handleClick issue de MyApp , c’est donc ce code-là qui s’exécute. Le code appelle setCount(count + 1) , incrémentant la variable d’état count . La nouvelle valeur count est passée comme prop à chaque bouton, de sorte qu’ils affichent tous cette nouvelle valeur. C’est ce qu’on appelle « faire remonter l’état » (“lifting state up”, NdT) . En déplaçant l’état vers le haut, nos composants peuvent le partager. App.js App.js Réinitialiser Fork import { useState } from 'react' ; export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Des compteurs synchronisés </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Cliqué { count } fois </ button > ) ; } Voir plus Et maintenant ?

Navigation React Native iOS Push Setup Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog React Native iOS Push Setup OpenAI Open in ChatGPT Step-by-step guide to setup APNS iOSpush notifications in your react native app. OpenAI Open in ChatGPT Major Release (V 1.0.0) 🚧 Starting from iOS version v1.0.0, we have introduced explicit push notification permission and option to add images in your notification. Also, introduced background mode for improved tracking of notification delivery. If you are using an iOS version older than v1.0.0 and upgrading to the new version. Please ensure to use the latest integration steps, especially for below methods: Adding Background mode capability (point 3 of capabilities) Calling registerPush method Tracking delivery methods 1 Add capabilities in iOS application Inside Targets select signing and capabilities Click on +capabilities and select Push Notifications and Background Modes In Background Modes, select Remote Notifications option. We use background notifications to receive delivery reports when your app is in quit and background state. Refer doc to know more about background notification 2 Register for push notifications Call registerForPushNotifications method below the SuprSend SDK initialised code which will register the iOS device for push service. If you have AppDelegate.m file then make follow code changes given in AppDelegate.h and AppDelegate.m file. If you have AppDelegate.swift file then make follow code changes given in AppDelegate.swift file. AppDelegate.h AppDelegate.m AppDelegate.swift Copy Ask AI #import <UserNotifications/UserNotifications.h> // Add this @interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate> // Add UNUserNotificationCenterDelegate in the already existing line 3 Asking User to send push notifications There are 2 ways in which your app can prompt the users to allow push notifications on their device: Explicit Authorization Explicit authorization allows you to display alerts, add a badge to the app icon, or play sounds whenever a notification is delivered. In this type of authorization, the request is made the first time user launches your app. If the user denies the request, you can’t send subsequent prompts to send the notification. Explicit authorization is our default authorization method as it automatically sets alert, sound and badge as soon as the user allows this request. Provisional Authorization (Supported in iOS 12.0 and above) Provisional notifications are sent quietly to the users —they don’t interrupt the user with a sound or banner. Also, they will not be shown when your app is in foreground. First time this type of notifications are sent, user is asked to “Keep” or “Turn off” the notifications. If they click on “Keep”, the further notifications continue to be sent Add below code in AppDelegate file for provisional authorization. AppDelegate.m AppDelegate.swift Copy Ask AI [SuprSend.shared configureWithConfiguration:configuration launchOptions:launchOptions]; // init code which is already added at time of initialisation UNAuthorizationOptions options = UNAuthorizationOptionAlert+UNAuthorizationOptionBadge+UNAuthorizationOptionSound; // Add this if (@available(iOS 12.0, *)) { options = options | UNAuthorizationOptionProvisional; } [SuprSend.shared registerForPushNotificationsWithOptions:options]; // Add this 4 Enable sending and tracking of push notifications To enable sending iOS APNS token to SuprSend backend, delivery and tracking of push notification delivery/clicks/dismiss events, add below 4 methods in AppDelegate file after last existing method. AppDelegate.m AppDelegate.swift Copy Ask AI - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSUInteger dataLength = deviceToken.length; if (dataLength == 0) { return; } const unsigned char *dataBuffer = (const unsigned char *)deviceToken.bytes; NSMutableString *hexString = [NSMutableString stringWithCapacity:(dataLength * 2)]; for (int i = 0; i < dataLength; ++i) { [hexString appendFormat:@"%02x", dataBuffer[i]]; } [SuprSend.shared setPushNotificationTokenWithToken:hexString]; } - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{ if (@available(iOS 14.0, *)) { completionHandler(UNAuthorizationOptionSound | UNNotificationPresentationOptionBanner | UNAuthorizationOptionBadge); } else { completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge); } } - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler API_AVAILABLE(ios(7.0)){ [SuprSend.shared application:application didReceiveRemoteNotification:userInfo]; completionHandler(UIBackgroundFetchResultNewData); } - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler{ if ([response isSuprSendNotification]) { [SuprSend.shared userNotificationCenter:center didReceive:response]; } completionHandler(); } @end // before this line iOS Push notifications only work on real devices so while developing/testing use real device to test it instead of simulators 5 Adding support for Notification service For better notification status (delivered, seen) tracking this step is needed. In Xcode go to File > New > Target . Select Notification Service Extension from the template list. Then in Next popup give it any product name, select your team, select swift language and click finish. After clicking on “Finish”, a folder will be created with your given product name. Inside that there will be NotificationService.swift file like below. In your project podFile add following snippet at the end of existing code like shown in image. Replace <your notification service name> with name you given to notification service while creating it. After that Run pod install . podFile Copy Ask AI target '<your notification service name>' do pod 'SuprsendCore' pod 'SuprSendSdk' end Replace the content in NotificationService.swift file with below code. In this snippet on line 11, 12 replace values with your workspace key and workspace secret.

X 可随时以任何理由或无理由暂停或终止你对付费服务的访问,停止向你提供全部或部分付费服务,或采取其认为适当的任何其他行动,例如冻结你的账号(不承担任何责任),包括但不限于以下任何原因: a. X 自行决定认为你违反了本条款或你对付费服务的使用违反了任何适用法律; b. X 被任何有管辖权的法院、监管机构或执法机构要求或指示这样做; c. X 遇到意外的技术或安全问题; d.

账号,这意味着你的购买将仅适用于在购买付费服务时所使用的账号,而不适用于你可能有权访问或控制的其他账号。如果你拥有或控制多个账号,并且希望在每个账号上使用付费服务,则必须为每个账号单独购买付费服务。 5.限制和义务。 a. 只有你所在国家/地区的法律允许你使用付费服务,并且 X 在你所居住的国家/地区支持适用的付费服务,你才能购买和使用付费服务。X 可以自行决定在某些国家/地区限制对付费服务的访问或购买。X 保留随时修改支持的国家/地区列表的权利。 b. 我们保留自行决定拒绝付费服务交易、取消或中止付费服务销售或使用的权利。 c.  你不得允许他人使用你的 X 账号访问其并未订购的任何付费服务。 d. 如果你是受到经济制裁(包括但不限于美国财政部外国资产控制办公室或任何其他适用的制裁机构实施的制裁)而不允许与美国人进行交易的人员(“" 受禁制人士 "”),则你不得购买或使用付费服务。这包括但不限于位于以下国家和地区或通常居住在以下国家和地区的人员:古巴、伊朗、乌克兰克里米亚地区、朝鲜和叙利亚。你声明并保证自己并非受禁制人士。 e. 你声明自己只会出于合法目的且仅按照条款使用付费服务。 税费 。 你有责任并同意支付与购买付费服务相关的任何适用税款、关税和费用,包括需要支付给 X

支付的金额(如有),两者以较高者为准。本小节的限制适用于任何责任理论,无论是基于保证、合同、法规、侵权行为(包括疏忽)还是其他,也无论 X 实体是否已被告知任何此类损害的可能性,即使本文所述的补救措施被发现未能达到其基本目的。“X 实体”是指 X、其母公司、附属公司、相关公司、管理人员、董事、员工、代理、代表、合作伙伴和许可方。 你所在司法管辖区的适用法律可能不允许某些责任限制。在你所在司法管辖区适用法律要求的范围内,上述规定并不限制 X 实体对欺诈、欺诈性虚假陈述、因我们的疏忽、重大疏忽和/或故意行为而造成的死亡或人身伤害的责任。在适用法律允许的最大范围内,X 实体对任何非排他性保证的最大累计责任仅限于一百美元 (US$100.00)。 4. 关于 Apple 的通知。 如果你购买了付费服务或在 iOS

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Learn React Quick Start Welcome to the React documentation! This page will give you an introduction to 80% of the React concepts that you will use on a daily basis. You will learn How to create and nest components How to add markup and styles How to display data How to render conditions and lists How to respond to events and update the screen How to share data between components Creating and nesting components React apps are made out of components . A component is a piece of the UI (user interface) that has its own logic and appearance. A component can be as small as a button, or as large as an entire page. React components are JavaScript functions that return markup: function MyButton ( ) { return ( < button > I'm a button </ button > ) ; } Now that you’ve declared MyButton , you can nest it into another component: export default function MyApp ( ) { return ( < div > < h1 > Welcome to my app </ h1 > < MyButton /> </ div > ) ; } Notice that <MyButton /> starts with a capital letter. That’s how you know it’s a React component. React component names must always start with a capital letter, while HTML tags must be lowercase. Have a look at the result: App.js App.js Reload Clear Fork function MyButton ( ) { return ( < button > I'm a button </ button > ) ; } export default function MyApp ( ) { return ( < div > < h1 > Welcome to my app </ h1 > < MyButton /> </ div > ) ; } Show more The export default keywords specify the main component in the file. If you’re not familiar with some piece of JavaScript syntax, MDN and javascript.info have great references. Writing markup with JSX The markup syntax you’ve seen above is called JSX . It is optional, but most React projects use JSX for its convenience. All of the tools we recommend for local development support JSX out of the box. JSX is stricter than HTML. You have to close tags like <br /> . Your component also can’t return multiple JSX tags. You have to wrap them into a shared parent, like a <div>...</div> or an empty <>...</> wrapper: function AboutPage ( ) { return ( < > < h1 > About </ h1 > < p > Hello there. < br /> How do you do? </ p > </ > ) ; } If you have a lot of HTML to port to JSX, you can use an online converter. Adding styles In React, you specify a CSS class with className . It works the same way as the HTML class attribute: < img className = "avatar" /> Then you write the CSS rules for it in a separate CSS file: /* In your CSS */ .avatar { border-radius : 50 % ; } React does not prescribe how you add CSS files. In the simplest case, you’ll add a <link> tag to your HTML. If you use a build tool or a framework, consult its documentation to learn how to add a CSS file to your project. Displaying data JSX lets you put markup into JavaScript. Curly braces let you “escape back” into JavaScript so that you can embed some variable from your code and display it to the user. For example, this will display user.name : return ( < h1 > { user . name } </ h1 > ) ; You can also “escape into JavaScript” from JSX attributes, but you have to use curly braces instead of quotes. For example, className="avatar" passes the "avatar" string as the CSS class, but src={user.imageUrl} reads the JavaScript user.imageUrl variable value, and then passes that value as the src attribute: return ( < img className = "avatar" src = { user . imageUrl } /> ) ; You can put more complex expressions inside the JSX curly braces too, for example, string concatenation : App.js App.js Reload Clear Fork const user = { name : 'Hedy Lamarr' , imageUrl : 'https://i.imgur.com/yXOvdOSs.jpg' , imageSize : 90 , } ; export default function Profile ( ) { return ( < > < h1 > { user . name } </ h1 > < img className = "avatar" src = { user . imageUrl } alt = { 'Photo of ' + user . name } style = { { width : user . imageSize , height : user . imageSize } } /> </ > ) ; } Show more In the above example, style={{}} is not a special syntax, but a regular {} object inside the style={ } JSX curly braces. You can use the style attribute when your styles depend on JavaScript variables. Conditional rendering In React, there is no special syntax for writing conditions. Instead, you’ll use the same techniques as you use when writing regular JavaScript code. For example, you can use an if statement to conditionally include JSX: let content ; if ( isLoggedIn ) { content = < AdminPanel /> ; } else { content = < LoginForm /> ; } return ( < div > { content } </ div > ) ; If you prefer more compact code, you can use the conditional ? operator. Unlike if , it works inside JSX: < div > { isLoggedIn ? ( < AdminPanel /> ) : ( < LoginForm /> ) } </ div > When you don’t need the else branch, you can also use a shorter logical && syntax : < div > { isLoggedIn && < AdminPanel /> } </ div > All of these approaches also work for conditionally specifying attributes. If you’re unfamiliar with some of this JavaScript syntax, you can start by always using if...else . Rendering lists You will rely on JavaScript features like for loop and the array map() function to render lists of components. For example, let’s say you have an array of products: const products = [ { title : 'Cabbage' , id : 1 } , { title : 'Garlic' , id : 2 } , { title : 'Apple' , id : 3 } , ] ; Inside your component, use the map() function to transform an array of products into an array of <li> items: const listItems = products . map ( product => < li key = { product . id } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; Notice how <li> has a key attribute. For each item in a list, you should pass a string or a number that uniquely identifies that item among its siblings. Usually, a key should be coming from your data, such as a database ID. React uses your keys to know what happened if you later insert, delete, or reorder the items. App.js App.js Reload Clear Fork const products = [ { title : 'Cabbage' , isFruit : false , id : 1 } , { title : 'Garlic' , isFruit : false , id : 2 } , { title : 'Apple' , isFruit : true , id : 3 } , ] ; export default function ShoppingList ( ) { const listItems = products . map ( product => < li key = { product . id } style = { { color : product . isFruit ? 'magenta' : 'darkgreen' } } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; } Show more Responding to events You can respond to events by declaring event handler functions inside your components: function MyButton ( ) { function handleClick ( ) { alert ( 'You clicked me!' ) ; } return ( < button onClick = { handleClick } > Click me </ button > ) ; } Notice how onClick={handleClick} has no parentheses at the end! Do not call the event handler function: you only need to pass it down . React will call your event handler when the user clicks the button. Updating the screen Often, you’ll want your component to “remember” some information and display it. For example, maybe you want to count the number of times a button is clicked. To do this, add state to your component. First, import useState from React: import { useState } from 'react' ; Now you can declare a state variable inside your component: function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; // ... You’ll get two things from useState : the current state ( count ), and the function that lets you update it ( setCount ). You can give them any names, but the convention is to write [something, setSomething] . The first time the button is displayed, count will be 0 because you passed 0 to useState() . When you want to change state, call setCount() and pass the new value to it. Clicking this button will increment the counter: function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Clicked { count } times </ button > ) ; } React will call your component function again. This time, count will be 1 . Then it will be 2 . And so on. If you render the same component multiple times, each will get its own state. Click each button separately: App.js App.js Reload Clear Fork import { useState } from 'react' ; export default function MyApp ( ) { return ( < div > < h1 > Counters that update separately </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Clicked { count } times </ button > ) ; } Show more Notice how each button “remembers” its own count state and doesn’t affect other buttons. Using Hooks Functions starting with use are called Hooks . useState is a built-in Hook provided by React. You can find other built-in Hooks in the API reference. You can also write your own Hooks by combining the existing ones. Hooks are more restrictive than other functions. You can only call Hooks at the top of your components (or other Hooks). If you want to use useState in a condition or a loop, extract a new component and put it there. Sharing data between components In the previous example, each MyButton had its own independent count , and when each button was clicked, only the count for the button clicked changed: Initially, each MyButton ’s count state is 0 The first MyButton updates its count to 1 However, often you’ll need components to share data and always update together . To make both MyButton components display the same count and update together, you need to move the state from the individual buttons “upwards” to the closest component containing all of them. In this example, it is MyApp : Initially, MyApp ’s count state is 0 and is passed down to both children On click, MyApp updates its count state to 1 and passes it down to both children Now when you click either button, the count in MyApp will change, which will change both of the counts in MyButton . Here’s how you can express this in code. First, move the state up from MyButton into MyApp : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update separately </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { // ... we're moving code from here ... } Then, pass the state down from MyApp to each MyButton , together with the shared click handler. You can pass information to MyButton using the JSX curly braces, just like you previously did with built-in tags like <img> : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update together </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } The information you pass down like this is called props . Now the MyApp component contains the count state and the handleClick event handler, and passes both of them down as props to each of the buttons. Finally, change MyButton to read the props you have passed from its parent component: function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Clicked { count } times </ button > ) ; } When you click the button, the onClick handler fires. Each button’s onClick prop was set to the handleClick function inside MyApp , so the code inside of it runs. That code calls setCount(count + 1) , incrementing the count state variable. The new count value is passed as a prop to each button, so they all show the new value. This is called “lifting state up”. By moving state up, you’ve shared it between components. App.js App.js Reload Clear Fork import { useState } from 'react' ; export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update together </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Clicked { count } times </ button > ) ; } Show more Next Steps By now, you know the basics of how to write React code!

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Simple statements | Theme Auto Light Dark | 7. Simple statements ¶ A simple statement is comprised within a single logical line. Several simple statements may occur on a single line separated by semicolons. The syntax for simple statements is: simple_stmt : expression_stmt | assert_stmt | assignment_stmt | augmented_assignment_stmt | annotated_assignment_stmt | pass_stmt | del_stmt | return_stmt | yield_stmt | raise_stmt | break_stmt | continue_stmt | import_stmt | future_stmt | global_stmt | nonlocal_stmt | type_stmt 7.1. Expression statements ¶ Expression statements are used (mostly interactively) to compute and write a value, or (usually) to call a procedure (a function that returns no meaningful result; in Python, procedures return the value None ). Other uses of expression statements are allowed and occasionally useful. The syntax for an expression statement is: expression_stmt : starred_expression An expression statement evaluates the expression list (which may be a single expression). In interactive mode, if the value is not None , it is converted to a string using the built-in repr() function and the resulting string is written to standard output on a line by itself (except if the result is None , so that procedure calls do not cause any output.) 7.2. Assignment statements ¶ Assignment statements are used to (re)bind names to values and to modify attributes or items of mutable objects: assignment_stmt : ( target_list "=" )+ ( starred_expression | yield_expression ) target_list : target ( "," target )* [ "," ] target : identifier | "(" [ target_list ] ")" | "[" [ target_list ] "]" | attributeref | subscription | slicing | "*" target (See section Primaries for the syntax definitions for attributeref , subscription , and slicing .) An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right. Assignment is defined recursively depending on the form of the target (list). When a target is part of a mutable object (an attribute reference, subscription or slicing), the mutable object must ultimately perform the assignment and decide about its validity, and may raise an exception if the assignment is unacceptable. The rules observed by various types and the exceptions raised are given with the definition of the object types (see section The standard type hierarchy ). Assignment of an object to a target list, optionally enclosed in parentheses or square brackets, is recursively defined as follows. If the target list is a single target with no trailing comma, optionally in parentheses, the object is assigned to that target. Else: If the target list contains one target prefixed with an asterisk, called a “starred” target: The object must be an iterable with at least as many items as there are targets in the target list, minus one. The first items of the iterable are assigned, from left to right, to the targets before the starred target. The final items of the iterable are assigned to the targets after the starred target. A list of the remaining items in the iterable is then assigned to the starred target (the list can be empty). Else: The object must be an iterable with the same number of items as there are targets in the target list, and the items are assigned, from left to right, to the corresponding targets. Assignment of an object to a single target is recursively defined as follows. If the target is an identifier (name): If the name does not occur in a global or nonlocal statement in the current code block: the name is bound to the object in the current local namespace. Otherwise: the name is bound to the object in the global namespace or the outer namespace determined by nonlocal , respectively. The name is rebound if it was already bound. This may cause the reference count for the object previously bound to the name to reach zero, causing the object to be deallocated and its destructor (if it has one) to be called. If the target is an attribute reference: The primary expression in the reference is evaluated. It should yield an object with assignable attributes; if this is not the case, TypeError is raised. That object is then asked to assign the assigned object to the given attribute; if it cannot perform the assignment, it raises an exception (usually but not necessarily AttributeError ). Note: If the object is a class instance and the attribute reference occurs on both sides of the assignment operator, the right-hand side expression, a.x can access either an instance attribute or (if no instance attribute exists) a class attribute. The left-hand side target a.x is always set as an instance attribute, creating it if necessary. Thus, the two occurrences of a.x do not necessarily refer to the same attribute: if the right-hand side expression refers to a class attribute, the left-hand side creates a new instance attribute as the target of the assignment: class Cls : x = 3 # class variable inst = Cls () inst . x = inst . x + 1 # writes inst.x as 4 leaving Cls.x as 3 This description does not necessarily apply to descriptor attributes, such as properties created with property() . If the target is a subscription: The primary expression in the reference is evaluated. It should yield either a mutable sequence object (such as a list) or a mapping object (such as a dictionary). Next, the subscript expression is evaluated. If the primary is a mutable sequence object (such as a list), the subscript must yield an integer. If it is negative, the sequence’s length is added to it. The resulting value must be a nonnegative integer less than the sequence’s length, and the sequence is asked to assign the assigned object to its item with that index. If the index is out of range, IndexError is raised (assignment to a subscripted sequence cannot add new items to a list). If the primary is a mapping object (such as a dictionary), the subscript must have a type compatible with the mapping’s key type, and the mapping is then asked to create a key/value pair which maps the subscript to the assigned object. This can either replace an existing key/value pair with the same key value, or insert a new key/value pair (if no key with the same value existed). For user-defined objects, the __setitem__() method is called with appropriate arguments. If the target is a slicing: The primary expression in the reference is evaluated. It should yield a mutable sequence object (such as a list). The assigned object should be a sequence object of the same type. Next, the lower and upper bound expressions are evaluated, insofar they are present; defaults are zero and the sequence’s length. The bounds should evaluate to integers. If either bound is negative, the sequence’s length is added to it. The resulting bounds are clipped to lie between zero and the sequence’s length, inclusive. Finally, the sequence object is asked to replace the slice with the items of the assigned sequence. The length of the slice may be different from the length of the assigned sequence, thus changing the length of the target sequence, if the target sequence allows it. CPython implementation detail: In the current implementation, the syntax for targets is taken to be the same as for expressions, and invalid syntax is rejected during the code generation phase, causing less detailed error messages. Although the definition of assignment implies that overlaps between the left-hand side and the right-hand side are ‘simultaneous’ (for example a, b = b, a swaps two variables), overlaps within the collection of assigned-to variables occur left-to-right, sometimes resulting in confusion. For instance, the following program prints [0, 2] : x = [ 0 , 1 ] i = 0 i , x [ i ] = 1 , 2 # i is updated, then x[i] is updated print ( x ) See also PEP 3132 - Extended Iterable Unpacking The specification for the *target feature. 7.2.1. Augmented assignment statements ¶ Augmented assignment is the combination, in a single statement, of a binary operation and an assignment statement: augmented_assignment_stmt : augtarget augop ( expression_list | yield_expression ) augtarget : identifier | attributeref | subscription | slicing augop : "+=" | "-=" | "*=" | "@=" | "/=" | "//=" | "%=" | "**=" | ">>=" | "<<=" | "&=" | "^=" | "|=" (See section Primaries for the syntax definitions of the last three symbols.) An augmented assignment evaluates the target (which, unlike normal assignment statements, cannot be an unpacking) and the expression list, performs the binary operation specific to the type of assignment on the two operands, and assigns the result to the original target. The target is only evaluated once. An augmented assignment statement like x += 1 can be rewritten as x = x + 1 to achieve a similar, but not exactly equal effect. In the augmented version, x is only evaluated once. Also, when possible, the actual operation is performed in-place , meaning that rather than creating a new object and assigning that to the target, the old object is modified instead. Unlike normal assignments, augmented assignments evaluate the left-hand side before evaluating the right-hand side. For example, a[i] += f(x) first looks-up a[i] , then it evaluates f(x) and performs the addition, and lastly, it writes the result back to a[i] . With the exception of assigning to tuples and multiple targets in a single statement, the assignment done by augmented assignment statements is handled the same way as normal assignments. Similarly, with the exception of the possible in-place behavior, the binary operation performed by augmented assignment is the same as the normal binary operations. For targets which are attribute references, the same caveat about class and instance attributes applies as for regular assignments. 7.2.2. Annotated assignment statements ¶ Annotation assignment is the combination, in a single statement, of a variable or attribute annotation and an optional assignment statement: annotated_assignment_stmt : augtarget ":" expression [ "=" ( starred_expression | yield_expression )] The difference from normal Assignment statements is that only a single target is allowed. The assignment target is considered “simple” if it consists of a single name that is not enclosed in parentheses. For simple assignment targets, if in class or module scope, the annotations are gathered in a lazily evaluated annotation scope . The annotations can be evaluated using the __annotations__ attribute of a class or module, or using the facilities in the annotationlib module. If the assignment target is not simple (an attribute, subscript node, or parenthesized name), the annotation is never evaluated. If a name is annotated in a function scope, then this name is local for that scope. Annotations are never evaluated and stored in function scopes. If the right hand side is present, an annotated assignment performs the actual assignment as if there was no annotation present. If the right hand side is not present for an expression target, then the interpreter evaluates the target except for the last __setitem__() or __setattr__() call. See also PEP 526 - Syntax for Variable Annotations The proposal that added syntax for annotating the types of variables (including class variables and instance variables), instead of expressing them through comments. PEP 484 - Type hints The proposal that added the typing module to provide a standard syntax for type annotations that can be used in static analysis tools and IDEs. Changed in version 3.8: Now annotated assignments allow the same expressions in the right hand side as regular assignments. Previously, some expressions (like un-parenthesized tuple expressions) caused a syntax error. Changed in version 3.14: Annotations are now lazily evaluated in a separate annotation scope . If the assignment target is not simple, annotations are never evaluated. 7.3. The assert statement ¶ Assert statements are a convenient way to insert debugging assertions into a program: assert_stmt : "assert" expression [ "," expression ] The simple form, assert expression , is equivalent to if __debug__ : if not expression : raise AssertionError The extended form, assert expression1, expression2 , is equivalent to if __debug__ : if not expression1 : raise AssertionError ( expression2 ) These equivalences assume that __debug__ and AssertionError refer to the built-in variables with those names. In the current implementation, the built-in variable __debug__ is True under normal circumstances, False when optimization is requested (command line option -O ). The current code generator emits no code for an assert statement when optimization is requested at compile time. Note that it is unnecessary to include the source code for the expression that failed in the error message; it will be displayed as part of the stack trace. Assignments to __debug__ are illegal. The value for the built-in variable is determined when the interpreter starts. 7.4. The pass statement ¶ pass_stmt : "pass" pass is a null operation — when it is executed, nothing happens. It is useful as a placeholder when a statement is required syntactically, but no code needs to be executed, for example: def f ( arg ): pass # a function that does nothing (yet) class C : pass # a class with no methods (yet) 7.5. The del statement ¶ del_stmt : "del" target_list Deletion is recursively defined very similar to the way assignment is defined. Rather than spelling it out in full details, here are some hints. Deletion of a target list recursively deletes each target, from left to right. Deletion of a name removes the binding of that name from the local or global namespace, depending on whether the name occurs in a global statement in the same code block. Trying to delete an unbound name raises a NameError exception. Deletion of attribute references, subscriptions and slicings is passed to the primary object involved; deletion of a slicing is in general equivalent to assignment of an empty slice of the right type (but even this is determined by the sliced object). Changed in version 3.2: Previously it was illegal to delete a name from the local namespace if it occurs as a free variable in a nested block. 7.6. The return statement ¶ return_stmt : "return" [ expression_list ] return may only occur syntactically nested in a function definition, not within a nested class definition. If an expression list is present, it is evaluated, else None is substituted. return leaves the current function call with the expression list (or None ) as return value. When return passes control out of a try statement with a finally clause, that finally clause is executed before really leaving the function. In a generator function, the return statement indicates that the generator is done and will cause StopIteration to be raised. The returned value (if any) is used as an argument to construct StopIteration and becomes the StopIteration.value attribute. In an asynchronous generator function, an empty return statement indicates that the asynchronous generator is done and will cause StopAsyncIteration to be raised. A non-empty return statement is a syntax error in an asynchronous generator function. 7.7. The yield statement ¶ yield_stmt : yield_expression A yield statement is semantically equivalent to a yield expression . The yield statement can be used to omit the parentheses that would otherwise be required in the equivalent yield expression statement. For example, the yield statements yield < expr > yield from < expr > are equivalent to the yield expression statements ( yield < expr > ) ( yield from < expr > ) Yield expressions and statements are only used when defining a generator function, and are only used in the body of the generator function. Using yield in a function definition is sufficient to cause that definition to create a generator function instead of a normal function. For full details of yield semantics, refer to the Yield expressions section. 7.8. The raise statement ¶ raise_stmt : "raise" [ expression [ "from" expression ]] If no expressions are present, raise re-raises the exception that is currently being handled, which is also known as the active exception . If there isn’t currently an active exception, a RuntimeError exception is raised indicating that this is an error. Otherwise, raise evaluates the first expression as the exception object. It must be either a subclass or an instance of BaseException . If it is a class, the exception instance will be obtained when needed by instantiating the class with no arguments. The type of the exception is the exception instance’s class, the value is the instance itself. A traceback object is normally created automatically when an exception is raised and attached to it as the __traceback__ attribute. You can create an exception and set your own traceback in one step using the with_traceback() exception method (which returns the same exception instance, with its traceback set to its argument), like so: raise Exception ( "foo occurred" ) . with_traceback ( tracebackobj ) The from clause is used for exception chaining: if given, the second expression must be another exception class or instance. If the second expression is an exception instance, it will be attached to the raised exception as the __cause__ attribute (which is writable). If the expression is an exception class, the class will be instantiated and the resulting exception instance will be attached to the raised exception as the __cause__ attribute. If the raised exception is not handled, both exceptions will be printed: >>> try : ... print ( 1 / 0 ) ... except Exception as exc : ... raise RuntimeError ( "Something bad happened" ) from exc ... Traceback (most recent call last): File "<stdin>" , line 2 , in <module> print ( 1 / 0 ) ~~^~~ ZeroDivisionError : division by zero The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<stdin>" , line 4 , in <module> raise RuntimeError ( "Something bad happened" ) from exc RuntimeError : Something bad happened A similar mechanism works implicitly if a new exception is raised when an exception is already being handled. An exception may be handled when an except or finally clause, or a with statement, is used. The previous exception is then attached as the new exception’s __context__ attribute: >>> try : ... print ( 1 / 0 ) ... except : ... raise RuntimeError ( "Something bad happened" ) ... Traceback (most recent call last): File "<stdin>" , line 2 , in <module> print ( 1 / 0 ) ~~^~~ ZeroDivisionError : division by zero During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>" , line 4 , in <module> raise RuntimeError ( "Something bad happened" ) RuntimeError : Something bad happened Exception chaining can be explicitly suppressed by specifying None in the from clause: >>> try : ... print ( 1 / 0 ) ... except : ... raise RuntimeError ( "Something bad happened" ) from None ... Traceback (most recent call last): File "<stdin>" , line 4 , in <module> RuntimeError : Something bad happened Additional information on exceptions can be found in section Exceptions , and information about handling exceptions is in section The try statement . Changed in version 3.3: None is now permitted as Y in raise X from Y . Added the __suppress_context__ attribute to suppress automatic display of the exception context. Changed in version 3.11: If the traceback of the active exception is modified in an except clause, a subsequent raise statement re-raises the exception with the modified traceback. Previously, the exception was re-raised with the traceback it had when it was caught. 7.9. The break statement ¶ break_stmt : "break" break may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop. It terminates the nearest enclosing loop, skipping the optional else clause if the loop has one. If a for loop is terminated by break , the loop control target keeps its current value. When break passes control out of a try statement with a finally clause, that finally clause is executed before really leaving the loop. 7.10. The continue statement ¶ continue_stmt : "continue" continue may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop. It continues with the next cycle of the nearest enclosing loop. When continue passes control out of a try statement with a finally clause, that finally clause is executed before really starting the next loop cycle. 7.11. The import statement ¶ import_stmt : "import" module [ "as" identifier ] ( "," module [ "as" identifier ])* | "from" relative_module "import" identifier [ "as" identifier ] ( "," identifier [ "as" identifier ])* | "from" relative_module "import" "(" identifier [ "as" identifier ] ( "," identifier [ "as" identifier ])* [ "," ] ")" | "from" relative_module "import" "*" module : ( identifier "." )* identifier relative_module : "." * module | "." + The basic import statement (no from clause) is executed in two steps: find a module, loading and initializing it if necessary define a name or names in the local namespace for the scope where the import statement occurs. When the statement contains multiple clauses (separated by commas) the two steps are carried out separately for each clause, just as though the clauses had been separated out into individual import statements. The details of the first step, finding and loading modules, are described in greater detail in the section on the import system , which also describes the various types of packages and modules that can be imported, as well as all the hooks that can be used to customize the import system. Note that failures in this step may indicate either that the module could not be located, or that an error occurred while initializing the module, which includes execution of the module’s code. If the requested module is retrieved successfully, it will be made available in the local namespace in one of three ways: If the module name is followed by as , then the name following as is bound directly to the imported module. If no other name is specified, and the module being imported is a top level module, the module’s name is bound in the local namespace as a reference to the imported module If the module being imported is not a top level module, then the name of the top level package that contains the module is bound in the local namespace as a reference to the top level package. The imported module must be accessed using its full qualified name rather than directly The from form uses a slightly more complex process: find the module specified in the from clause, loading and initializing it if necessary; for each of the identifiers specified in the import clauses: check if the imported module has an attribute by that name if not, attempt to import a submodule with that name and then check the imported module again for that attribute if the attribute is not found, ImportError is raised. otherwise, a reference to that value is stored in the local namespace, using the name in the as clause if it is present, otherwise using the attribute name Examples: import foo # foo imported and bound locally import foo.bar.baz # foo, foo.bar, and foo.bar.baz imported, foo bound locally import foo.bar.baz as fbb # foo, foo.bar, and foo.bar.baz imported, foo.bar.baz bound as fbb from foo.bar import baz # foo, foo.bar, and foo.bar.baz imported, foo.bar.baz bound as baz from foo import attr # foo imported and foo.attr bound as attr If the list of identifiers is replaced by a star ( '*' ), all public names defined in the module are bound in the local namespace for the scope where the import statement occurs. The public names defined by a module are determined by checking the module’s namespace for a variable named __all__ ; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ( '_' ). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module). The wild card form of import — from module import * — is only allowed at the module level. Attempting to use it in class or function definitions will raise a SyntaxError . When specifying what module to import you do not have to specify the absolute name of the module. When a module or package is contained within another package it is possible to make a relative import within the same top package without having to mention the package name. By using leading dots in the specified module or package after from you can specify how high to traverse up the current package hierarchy without specifying exact names. One leading dot means the current package where the module making the import exists. Two dots means up one package level. Three dots is up two levels, etc. So if you execute from . import mod from a module in the pkg package then you will end up importing pkg.mod . If you execute from ..subpkg2 import mod from within pkg.subpkg1 you will import pkg.subpkg2.mod . The specification for relative imports is contained in the Package Relative Imports section. importlib.import_module() is provided to support applications that determine dynamically the modules to be loaded. Raises an auditing event import with arguments module , filename , sys.path , sys.meta_path , sys.path_hooks . 7.11.1. Future statements ¶ A future statement is a directive to the compiler that a particular module should be compiled using syntax or semantics that will be available in a specified future release of Python where the feature becomes standard. The future statement is intended to ease migration to future versions of Python that introduce incompatible changes to the language. It allows use of the new features on a per-module basis before the release in which the feature becomes standard. future_stmt : "from" "__future__" "import" feature [ "as" identifier ] ( "," feature [ "as" identifier ])* | "from" "__future__" "import" "(" feature [ "as" identifier ] ( "," feature [ "as" identifier ])* [ "," ] ")" feature : identifier A future statement must appear near the top of the module. The only lines that can appear before a future statement are: the module docstring (if any), comments, blank lines, and other future statements. The only feature that requires using the future statement is annotations (see PEP 563 ). All historical features enabled by the future statement are still recognized by Python 3. The list includes absolute_import , division , generators , generator_stop , unicode_literals , print_function , nested_scopes and with_statement . They are all redundant because they are always enabled, and only kept for backwards compatibility. A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime. For any given release, the compiler knows which feature names have been defined, and raises a compile-time error if a future statement contains a feature not known to it. The direct runtime semantics are the same as for any import statement: there is a standard module __future__ , described later, and it will be imported in the usual way at the time the future statement is executed. The interesting runtime semantics depend on the specific feature enabled by the future statement. Note that there is nothing special about the statement: import __future__ [ as name ] That is not a future statement; it’s an ordinary import statement with no special semantics or syntax restrictions. Code compiled by calls to the built-in functions exec() and compile() that occur in a module M containing a future statement will, by default, use the new syntax or semantics associated with the future statement. This can be controlled by optional arguments to compile() — see the documentation of that function for details. A future statement typed at an interactive interpreter prompt will take effect for the rest of the interpreter session. If an interpreter is started with the -i option, is passed a script name to execute, and the script includes a future statement, it will be in effect in the interactive session started after the script is executed. See also PEP 236 - Back to the __future__ The original proposal for the __future__ mechanism. 7.12. The global statement ¶ global_stmt : "global" identifier ( "," identifier )* The global statement causes the listed identifiers to be interpreted as globals. It would be impossible to assign to a global variable without global , although free variables may refer to globals without being declared global. The global statement applies to the entire current scope (module, function body or class definition). A SyntaxError is raised if a variable is used or assigned to prior to its global declaration in the scope. At the module level, all variables are global, so a global statement has no effect. However, variables must still not be used or assigned to prior to their global declaration. This requirement is relaxed in the interactive prompt ( REPL ). Programmer’s note: global is a directive to the parser. It applies only to code parsed at the same time as the global statement. In particular, a global statement contained in a string or code object supplied to the built-in exec() function does not affect the code block containing the function call, and code contained in such a string is unaffected by global statements in the code containing the function call. The same applies to the eval() and compile() functions. 7.13. The nonlocal statement ¶ nonlocal_stmt : "nonlocal" identifier ( "," identifier )* When the definition of a function or class is nested (enclosed) within the definitions of other functions, its nonlocal scopes are the local scopes of the enclosing functions. The nonlocal statement causes the listed identifiers to refer to names previously bound in nonlocal scopes. It allows encapsulated code to rebind such nonlocal identifiers. If a name is bound in more than one nonlocal scope, the nearest binding is used. If a name is not bound in any nonlocal scope, or if there is no nonlocal scope, a SyntaxError is raised. The nonlocal statement applies to the entire scope of a function or class body. A SyntaxError is raised if a variable is used or assigned to prior to its nonlocal declaration in the scope. See also PEP 3104 - Access to Names in Outer Scopes The specification for the nonlocal statement. Programmer’s note: nonlocal is a directive to the parser and applies only to code parsed along with it. See the note for the global statement. 7.14. The type statement ¶ type_stmt : 'type' identifier [ type_params ] "=" expression The type statement declares a type alias, which is an instance of typing.TypeAliasType . For example, the following statement creates a type alias: type Point = tuple [ float , float ] This code is roughly equivalent to: annotation - def VALUE_OF_Point (): return tuple [ float , float ] Point = typing . TypeAliasType ( "Point" , VALUE_OF_Point ()) annotation-def indicates an annotation scope , which behaves mostly like a function, but with several small differences. The value of the type alias is evaluated in the annotation scope. It is not evaluated when the type alias is created, but only when the value is accessed through the type alias’s __value__ attribute (see Lazy evaluation ). This allows the type alias to refer to names that are not yet defined. Type aliases may be made generic by adding a type parameter list after the name. See Generic type aliases for more. type is a soft keyword . Added in version 3.12. See also PEP 695 - Type Parameter Syntax Introduced the type statement and syntax for generic classes and functions.

React React v 19.2 Search ⌘ Ctrl K Öğren Referans Topluluk Blog React Web ve yerel (native) kullanıcı arayüzü için kütüphane React'ı öğrenin API Tanımları Bileşenlerden kullanıcı arayüzleri oluşturun React, bileşen adı verilen birbirinden ayrı parçalardan kullanıcı arayüzü oluşturmanızı sağlar. Thumbnail , LikeButton ve Video gibi kendi React bileşenlerinizi oluşturabilirsiniz. Ardından bunları birleştirerek tam ekranlara, sayfalara ve uygulamalara çevirebilirsiniz. Video.js function Video ( { video } ) { return ( < div > < Thumbnail video = { video } /> < a href = { video . url } > < h3 > { video . title } </ h3 > < p > { video . description } </ p > </ a > < LikeButton video = { video } /> </ div > ) ; } My video Video description İster tek başınıza ister diğer binlerce geliştirici ile çalışın, React kullanmak aynı hissettirir. React diğer insanlar, gruplar veya organizasyonlar tarafından yazılmış bileşenleri sorunsuz bir şekilde birleştirebilmeniz için tasarlanmıştır. Kod ve işaretleme kullanarak bileşenler yazın React bileşenleri aslında JavaScript fonksiyonlarıdır. Bazı içerikleri koşullu olarak göstermek mi istiyorsunuz? Bir if ifadesi kullanın. Bir liste mi göstermek istiyorsunuz? Dizi map() fonksiyonunu deneyin. React öğrenmek programlamayı öğrenmektir. VideoList.js function VideoList ( { videos , emptyHeading } ) { const count = videos . length ; let heading = emptyHeading ; if ( count > 0 ) { const noun = count > 1 ? 'Videos' : 'Video' ; heading = count + ' ' + noun ; } return ( < section > < h2 > { heading } </ h2 > { videos . map ( video => < Video key = { video . id } video = { video } /> ) } </ section > ) ; } 3 Videos First video Video description Second video Video description Third video Video description Bu işaretleme sözdizimine JSX denir. React tarafından popüler hale getirilen bir JavaScript sözdizimi uzantısıdır. JSX işaretlemesini ilgili render etme mantığına yakın yerleştirmek, React bileşenlerini oluşturmayı, bakımını ve silmeyi kolaylaştırır. İhtiyacınız olan her yere interaktivite ekleyin React bileşenleri veri alır ve ekranda görüntülenecek olanı döndürür. Kullanıcı girişi gibi bir etkileşime yanıt olarak bileşenlere yeni veri yollayabilirsiniz. React daha sonra ekranı yeni veriyle eşleşecek şekilde günceller. SearchableVideoList.js import { useState } from 'react' ; function SearchableVideoList ( { videos } ) { const [ searchText , setSearchText ] = useState ( '' ) ; const foundVideos = filterVideos ( videos , searchText ) ; return ( < > < SearchInput value = { searchText } onChange = { newText => setSearchText ( newText ) } /> < VideoList videos = { foundVideos } emptyHeading = { `No matches for “ ${ searchText } ”` } /> </ > ) ; } example.com / videos.html React Videos A brief history of React Search 5 Videos React: The Documentary The origin story of React Rethinking Best Practices Pete Hunt (2013) Introducing React Native Tom Occhino (2015) Introducing React Hooks Sophie Alpert and Dan Abramov (2018) Introducing Server Components Dan Abramov and Lauren Tan (2020) Tüm sayfanızı React ile oluşturmak zorunda değilsiniz.

İnsanlar yerel (native) uygulamaların kendi platformları gibi görünüp hisettirmelerini bekliyorlar. React Native ve Expo , React ile Android, iOS ve daha fazlası için uygulama oluşturmanıza olanak tanır. Arayüzleri yerel (native) gibi gözükür ve hissettirir, çünkü gerçekten öyleler. Bu bir web görünümü (webview) değil. React bileşenleriniz, platform tarafından sağlanan gerçek Android ve iOS viewlarını render eder. React ile web ve yerel (native) geliştirici olabilirsiniz. Takımınız, kullanıcı deneyimini feda etmeden birçok platforma uygulama yapabilir. Organizasyonunuz, platform farklılıklarını bağdaştırabilir ve baştan sona tüm özelliklere sahip olan takımlar oluşturabilir.

Learn React Quick Start Welcome to the React documentation! This page will give you an introduction to 80% of the React concepts that you will use on a daily basis. You will learn How to create and nest components How to add markup and styles How to display data How to render conditions and lists How to respond to events and update the screen How to share data between components Creating and nesting components React apps are made out of components . A component is a piece of the UI (user interface) that has its own logic and appearance. A component can be as small as a button, or as large as an entire page. React components are JavaScript functions that return markup: function MyButton ( ) { return ( < button > I'm a button </ button > ) ; } Now that you’ve declared MyButton , you can nest it into another component: export default function MyApp ( ) { return ( < div > < h1 > Welcome to my app </ h1 > < MyButton /> </ div > ) ; } Notice that <MyButton /> starts with a capital letter. That’s how you know it’s a React component. React component names must always start with a capital letter, while HTML tags must be lowercase. Have a look at the result: App.js App.js Reload Clear Fork function MyButton ( ) { return ( < button > I'm a button </ button > ) ; } export default function MyApp ( ) { return ( < div > < h1 > Welcome to my app </ h1 > < MyButton /> </ div > ) ; } Show more The export default keywords specify the main component in the file. If you’re not familiar with some piece of JavaScript syntax, MDN and javascript.info have great references. Writing markup with JSX The markup syntax you’ve seen above is called JSX . It is optional, but most React projects use JSX for its convenience. All of the tools we recommend for local development support JSX out of the box. JSX is stricter than HTML. You have to close tags like <br /> . Your component also can’t return multiple JSX tags. You have to wrap them into a shared parent, like a <div>...</div> or an empty <>...</> wrapper: function AboutPage ( ) { return ( < > < h1 > About </ h1 > < p > Hello there. < br /> How do you do? </ p > </ > ) ; } If you have a lot of HTML to port to JSX, you can use an online converter. Adding styles In React, you specify a CSS class with className . It works the same way as the HTML class attribute: < img className = "avatar" /> Then you write the CSS rules for it in a separate CSS file: /* In your CSS */ .avatar { border-radius : 50 % ; } React does not prescribe how you add CSS files. In the simplest case, you’ll add a <link> tag to your HTML. If you use a build tool or a framework, consult its documentation to learn how to add a CSS file to your project. Displaying data JSX lets you put markup into JavaScript. Curly braces let you “escape back” into JavaScript so that you can embed some variable from your code and display it to the user. For example, this will display user.name : return ( < h1 > { user . name } </ h1 > ) ; You can also “escape into JavaScript” from JSX attributes, but you have to use curly braces instead of quotes. For example, className="avatar" passes the "avatar" string as the CSS class, but src={user.imageUrl} reads the JavaScript user.imageUrl variable value, and then passes that value as the src attribute: return ( < img className = "avatar" src = { user . imageUrl } /> ) ; You can put more complex expressions inside the JSX curly braces too, for example, string concatenation : App.js App.js Reload Clear Fork const user = { name : 'Hedy Lamarr' , imageUrl : 'https://i.imgur.com/yXOvdOSs.jpg' , imageSize : 90 , } ; export default function Profile ( ) { return ( < > < h1 > { user . name } </ h1 > < img className = "avatar" src = { user . imageUrl } alt = { 'Photo of ' + user . name } style = { { width : user . imageSize , height : user . imageSize } } /> </ > ) ; } Show more In the above example, style={{}} is not a special syntax, but a regular {} object inside the style={ } JSX curly braces. You can use the style attribute when your styles depend on JavaScript variables. Conditional rendering In React, there is no special syntax for writing conditions. Instead, you’ll use the same techniques as you use when writing regular JavaScript code. For example, you can use an if statement to conditionally include JSX: let content ; if ( isLoggedIn ) { content = < AdminPanel /> ; } else { content = < LoginForm /> ; } return ( < div > { content } </ div > ) ; If you prefer more compact code, you can use the conditional ? operator. Unlike if , it works inside JSX: < div > { isLoggedIn ? ( < AdminPanel /> ) : ( < LoginForm /> ) } </ div > When you don’t need the else branch, you can also use a shorter logical && syntax : < div > { isLoggedIn && < AdminPanel /> } </ div > All of these approaches also work for conditionally specifying attributes. If you’re unfamiliar with some of this JavaScript syntax, you can start by always using if...else . Rendering lists You will rely on JavaScript features like for loop and the array map() function to render lists of components. For example, let’s say you have an array of products: const products = [ { title : 'Cabbage' , id : 1 } , { title : 'Garlic' , id : 2 } , { title : 'Apple' , id : 3 } , ] ; Inside your component, use the map() function to transform an array of products into an array of <li> items: const listItems = products . map ( product => < li key = { product . id } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; Notice how <li> has a key attribute. For each item in a list, you should pass a string or a number that uniquely identifies that item among its siblings. Usually, a key should be coming from your data, such as a database ID. React uses your keys to know what happened if you later insert, delete, or reorder the items. App.js App.js Reload Clear Fork const products = [ { title : 'Cabbage' , isFruit : false , id : 1 } , { title : 'Garlic' , isFruit : false , id : 2 } , { title : 'Apple' , isFruit : true , id : 3 } , ] ; export default function ShoppingList ( ) { const listItems = products . map ( product => < li key = { product . id } style = { { color : product . isFruit ? 'magenta' : 'darkgreen' } } > { product . title } </ li > ) ; return ( < ul > { listItems } </ ul > ) ; } Show more Responding to events You can respond to events by declaring event handler functions inside your components: function MyButton ( ) { function handleClick ( ) { alert ( 'You clicked me!' ) ; } return ( < button onClick = { handleClick } > Click me </ button > ) ; } Notice how onClick={handleClick} has no parentheses at the end! Do not call the event handler function: you only need to pass it down . React will call your event handler when the user clicks the button. Updating the screen Often, you’ll want your component to “remember” some information and display it. For example, maybe you want to count the number of times a button is clicked. To do this, add state to your component. First, import useState from React: import { useState } from 'react' ; Now you can declare a state variable inside your component: function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; // ... You’ll get two things from useState : the current state ( count ), and the function that lets you update it ( setCount ). You can give them any names, but the convention is to write [something, setSomething] . The first time the button is displayed, count will be 0 because you passed 0 to useState() . When you want to change state, call setCount() and pass the new value to it. Clicking this button will increment the counter: function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Clicked { count } times </ button > ) ; } React will call your component function again. This time, count will be 1 . Then it will be 2 . And so on. If you render the same component multiple times, each will get its own state. Click each button separately: App.js App.js Reload Clear Fork import { useState } from 'react' ; export default function MyApp ( ) { return ( < div > < h1 > Counters that update separately </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < button onClick = { handleClick } > Clicked { count } times </ button > ) ; } Show more Notice how each button “remembers” its own count state and doesn’t affect other buttons. Using Hooks Functions starting with use are called Hooks . useState is a built-in Hook provided by React. You can find other built-in Hooks in the API reference. You can also write your own Hooks by combining the existing ones. Hooks are more restrictive than other functions. You can only call Hooks at the top of your components (or other Hooks). If you want to use useState in a condition or a loop, extract a new component and put it there. Sharing data between components In the previous example, each MyButton had its own independent count , and when each button was clicked, only the count for the button clicked changed: Initially, each MyButton ’s count state is 0 The first MyButton updates its count to 1 However, often you’ll need components to share data and always update together . To make both MyButton components display the same count and update together, you need to move the state from the individual buttons “upwards” to the closest component containing all of them. In this example, it is MyApp : Initially, MyApp ’s count state is 0 and is passed down to both children On click, MyApp updates its count state to 1 and passes it down to both children Now when you click either button, the count in MyApp will change, which will change both of the counts in MyButton . Here’s how you can express this in code. First, move the state up from MyButton into MyApp : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update separately </ h1 > < MyButton /> < MyButton /> </ div > ) ; } function MyButton ( ) { // ... we're moving code from here ... } Then, pass the state down from MyApp to each MyButton , together with the shared click handler. You can pass information to MyButton using the JSX curly braces, just like you previously did with built-in tags like <img> : export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update together </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } The information you pass down like this is called props . Now the MyApp component contains the count state and the handleClick event handler, and passes both of them down as props to each of the buttons. Finally, change MyButton to read the props you have passed from its parent component: function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Clicked { count } times </ button > ) ; } When you click the button, the onClick handler fires. Each button’s onClick prop was set to the handleClick function inside MyApp , so the code inside of it runs. That code calls setCount(count + 1) , incrementing the count state variable. The new count value is passed as a prop to each button, so they all show the new value. This is called “lifting state up”. By moving state up, you’ve shared it between components. App.js App.js Reload Clear Fork import { useState } from 'react' ; export default function MyApp ( ) { const [ count , setCount ] = useState ( 0 ) ; function handleClick ( ) { setCount ( count + 1 ) ; } return ( < div > < h1 > Counters that update together </ h1 > < MyButton count = { count } onClick = { handleClick } /> < MyButton count = { count } onClick = { handleClick } /> </ div > ) ; } function MyButton ( { count , onClick } ) { return ( < button onClick = { onClick } > Clicked { count } times </ button > ) ; } Show more Next Steps By now, you know the basics of how to write React code!

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible?

All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

Follow Episode Details Phil and Matt talk with Marc-Andre Giroux, a developer working at Github who helps maintain their REST and GraphQL APIs. Show Notes A quick note before we get started: We recorded this episode back in April of 2020 when everyone was quarantining and making bread to post on instagram. Fast forward to now, in June, American cities, and cities around the world are joining in, protesting the systemic racism that has long been an issue in our societies. While our energy and focus turned to current events, editing this episode took a seat on the backburner. That said, we have it ready… but it couldn’t be released at a worse time. Three white dudes talking about APIs while our friends in other communities are fighting injustices that have long kept them down seems to be a bit tone deaf, and we know that, recognize that and commit ourselves to being involved. There are a lot of conversations we want to have around this topic both in the API world, and outside of it. We don’t want this episode to take away from the discussions going on around such important and heavy topics, but we hope this can serve as a way for you to take a break while you travel to and from a protest. If you are going to protest please be safe, drink as much water as you can to stay hydrated in the heat and know that things are changing for the better. To all the Black API developers out there: we see you, we're fighting with you, and we want you to know that we're listening.  From all of us at APIs You Won't Hate: Black lives matter. Recorded back in April, Matt and Phil are joined by Marc-Andre Giroux to talk about the APIs he works on at Github and his fascination of GraphQL. Marc-Andre recently released a book titled " Production Ready GraphQL " where he talks about schema design, tooling, architecture and more. We take a dive into knowing when GraphQL is the right tool for the job, versus when to use REST and talk a little about the whole quarantine thing that was happening. Sponsors: Stoplight makes it possible for us to bring you this podcast while we nerd out about APIs. Check them out for their tooling around documentation with Studio, an app that makes API documentation an absolute joy to work with.

Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

More Control Flow Tools | Theme Auto Light Dark | 4. More Control Flow Tools ¶ As well as the while statement just introduced, Python uses a few more that we will encounter in this chapter. 4.1. if Statements ¶ Perhaps the most well-known statement type is the if statement. For example: >>> x = int ( input ( "Please enter an integer: " )) Please enter an integer: 42 >>> if x < 0 : ... x = 0 ... print ( 'Negative changed to zero' ) ... elif x == 0 : ... print ( 'Zero' ) ... elif x == 1 : ... print ( 'Single' ) ... else : ... print ( 'More' ) ... More There can be zero or more elif parts, and the else part is optional. The keyword ‘ elif ’ is short for ‘else if’, and is useful to avoid excessive indentation. An if … elif … elif … sequence is a substitute for the switch or case statements found in other languages. If you’re comparing the same value to several constants, or checking for specific types or attributes, you may also find the match statement useful. For more details see match Statements . 4.2. for Statements ¶ The for statement in Python differs a bit from what you may be used to in C or Pascal. Rather than always iterating over an arithmetic progression of numbers (like in Pascal), or giving the user the ability to define both the iteration step and halting condition (as C), Python’s for statement iterates over the items of any sequence (a list or a string), in the order that they appear in the sequence. For example (no pun intended): >>> # Measure some strings: >>> words = [ 'cat' , 'window' , 'defenestrate' ] >>> for w in words : ... print ( w , len ( w )) ... cat 3 window 6 defenestrate 12 Code that modifies a collection while iterating over that same collection can be tricky to get right. Instead, it is usually more straight-forward to loop over a copy of the collection or to create a new collection: # Create a sample collection users = { 'Hans' : 'active' , 'Éléonore' : 'inactive' , '景太郎' : 'active' } # Strategy: Iterate over a copy for user , status in users . copy () . items (): if status == 'inactive' : del users [ user ] # Strategy: Create a new collection active_users = {} for user , status in users . items (): if status == 'active' : active_users [ user ] = status 4.3. The range() Function ¶ If you do need to iterate over a sequence of numbers, the built-in function range() comes in handy. It generates arithmetic progressions: >>> for i in range ( 5 ): ... print ( i ) ... 0 1 2 3 4 The given end point is never part of the generated sequence; range(10) generates 10 values, the legal indices for items of a sequence of length 10. It is possible to let the range start at another number, or to specify a different increment (even negative; sometimes this is called the ‘step’): >>> list ( range ( 5 , 10 )) [5, 6, 7, 8, 9] >>> list ( range ( 0 , 10 , 3 )) [0, 3, 6, 9] >>> list ( range ( - 10 , - 100 , - 30 )) [-10, -40, -70] To iterate over the indices of a sequence, you can combine range() and len() as follows: >>> a = [ 'Mary' , 'had' , 'a' , 'little' , 'lamb' ] >>> for i in range ( len ( a )): ... print ( i , a [ i ]) ... 0 Mary 1 had 2 a 3 little 4 lamb In most such cases, however, it is convenient to use the enumerate() function, see Looping Techniques . A strange thing happens if you just print a range: >>> range ( 10 ) range(0, 10) In many ways the object returned by range() behaves as if it is a list, but in fact it isn’t. It is an object which returns the successive items of the desired sequence when you iterate over it, but it doesn’t really make the list, thus saving space. We say such an object is iterable , that is, suitable as a target for functions and constructs that expect something from which they can obtain successive items until the supply is exhausted. We have seen that the for statement is such a construct, while an example of a function that takes an iterable is sum() : >>> sum ( range ( 4 )) # 0 + 1 + 2 + 3 6 Later we will see more functions that return iterables and take iterables as arguments. In chapter Data Structures , we will discuss in more detail about list() . 4.4. break and continue Statements ¶ The break statement breaks out of the innermost enclosing for or while loop: >>> for n in range ( 2 , 10 ): ... for x in range ( 2 , n ): ... if n % x == 0 : ... print ( f " { n } equals { x } * { n // x } " ) ... break ... 4 equals 2 * 2 6 equals 2 * 3 8 equals 2 * 4 9 equals 3 * 3 The continue statement continues with the next iteration of the loop: >>> for num in range ( 2 , 10 ): ... if num % 2 == 0 : ... print ( f "Found an even number { num } " ) ... continue ... print ( f "Found an odd number { num } " ) ... Found an even number 2 Found an odd number 3 Found an even number 4 Found an odd number 5 Found an even number 6 Found an odd number 7 Found an even number 8 Found an odd number 9 4.5. else Clauses on Loops ¶ In a for or while loop the break statement may be paired with an else clause. If the loop finishes without executing the break , the else clause executes. In a for loop, the else clause is executed after the loop finishes its final iteration, that is, if no break occurred. In a while loop, it’s executed after the loop’s condition becomes false. In either kind of loop, the else clause is not executed if the loop was terminated by a break . Of course, other ways of ending the loop early, such as a return or a raised exception, will also skip execution of the else clause. This is exemplified in the following for loop, which searches for prime numbers: >>> for n in range ( 2 , 10 ): ... for x in range ( 2 , n ): ... if n % x == 0 : ... print ( n , 'equals' , x , '*' , n // x ) ... break ... else : ... # loop fell through without finding a factor ... print ( n , 'is a prime number' ) ... 2 is a prime number 3 is a prime number 4 equals 2 * 2 5 is a prime number 6 equals 2 * 3 7 is a prime number 8 equals 2 * 4 9 equals 3 * 3 (Yes, this is the correct code. Look closely: the else clause belongs to the for loop, not the if statement.) One way to think of the else clause is to imagine it paired with the if inside the loop. As the loop executes, it will run a sequence like if/if/if/else. The if is inside the loop, encountered a number of times. If the condition is ever true, a break will happen. If the condition is never true, the else clause outside the loop will execute. When used with a loop, the else clause has more in common with the else clause of a try statement than it does with that of if statements: a try statement’s else clause runs when no exception occurs, and a loop’s else clause runs when no break occurs. For more on the try statement and exceptions, see Handling Exceptions . 4.6. pass Statements ¶ The pass statement does nothing. It can be used when a statement is required syntactically but the program requires no action. For example: >>> while True : ... pass # Busy-wait for keyboard interrupt (Ctrl+C) ... This is commonly used for creating minimal classes: >>> class MyEmptyClass : ... pass ... Another place pass can be used is as a place-holder for a function or conditional body when you are working on new code, allowing you to keep thinking at a more abstract level. The pass is silently ignored: >>> def initlog ( * args ): ... pass # Remember to implement this! ... For this last case, many people use the ellipsis literal ... instead of pass . This use has no special meaning to Python, and is not part of the language definition (you could use any constant expression here), but ... is used conventionally as a placeholder body as well. See The Ellipsis Object . 4.7. match Statements ¶ A match statement takes an expression and compares its value to successive patterns given as one or more case blocks. This is superficially similar to a switch statement in C, Java or JavaScript (and many other languages), but it’s more similar to pattern matching in languages like Rust or Haskell. Only the first pattern that matches gets executed and it can also extract components (sequence elements or object attributes) from the value into variables. If no case matches, none of the branches is executed. The simplest form compares a subject value against one or more literals: def http_error ( status ): match status : case 400 : return "Bad request" case 404 : return "Not found" case 418 : return "I'm a teapot" case _ : return "Something's wrong with the internet" Note the last block: the “variable name” _ acts as a wildcard and never fails to match. You can combine several literals in a single pattern using | (“or”): case 401 | 403 | 404 : return "Not allowed" Patterns can look like unpacking assignments, and can be used to bind variables: # point is an (x, y) tuple match point : case ( 0 , 0 ): print ( "Origin" ) case ( 0 , y ): print ( f "Y= { y } " ) case ( x , 0 ): print ( f "X= { x } " ) case ( x , y ): print ( f "X= { x } , Y= { y } " ) case _ : raise ValueError ( "Not a point" ) Study that one carefully! The first pattern has two literals, and can be thought of as an extension of the literal pattern shown above. But the next two patterns combine a literal and a variable, and the variable binds a value from the subject ( point ). The fourth pattern captures two values, which makes it conceptually similar to the unpacking assignment (x, y) = point . If you are using classes to structure your data you can use the class name followed by an argument list resembling a constructor, but with the ability to capture attributes into variables: class Point : def __init__ ( self , x , y ): self . x = x self . y = y def where_is ( point ): match point : case Point ( x = 0 , y = 0 ): print ( "Origin" ) case Point ( x = 0 , y = y ): print ( f "Y= { y } " ) case Point ( x = x , y = 0 ): print ( f "X= { x } " ) case Point (): print ( "Somewhere else" ) case _ : print ( "Not a point" ) You can use positional parameters with some builtin classes that provide an ordering for their attributes (e.g. dataclasses). You can also define a specific position for attributes in patterns by setting the __match_args__ special attribute in your classes. If it’s set to (“x”, “y”), the following patterns are all equivalent (and all bind the y attribute to the var variable): Point ( 1 , var ) Point ( 1 , y = var ) Point ( x = 1 , y = var ) Point ( y = var , x = 1 ) A recommended way to read patterns is to look at them as an extended form of what you would put on the left of an assignment, to understand which variables would be set to what. Only the standalone names (like var above) are assigned to by a match statement. Dotted names (like foo.bar ), attribute names (the x= and y= above) or class names (recognized by the “(…)” next to them like Point above) are never assigned to. Patterns can be arbitrarily nested. For example, if we have a short list of Points, with __match_args__ added, we could match it like this: class Point : __match_args__ = ( 'x' , 'y' ) def __init__ ( self , x , y ): self . x = x self . y = y match points : case []: print ( "No points" ) case [ Point ( 0 , 0 )]: print ( "The origin" ) case [ Point ( x , y )]: print ( f "Single point { x } , { y } " ) case [ Point ( 0 , y1 ), Point ( 0 , y2 )]: print ( f "Two on the Y axis at { y1 } , { y2 } " ) case _ : print ( "Something else" ) We can add an if clause to a pattern, known as a “guard”. If the guard is false, match goes on to try the next case block. Note that value capture happens before the guard is evaluated: match point : case Point ( x , y ) if x == y : print ( f "Y=X at { x } " ) case Point ( x , y ): print ( f "Not on the diagonal" ) Several other key features of this statement: Like unpacking assignments, tuple and list patterns have exactly the same meaning and actually match arbitrary sequences. An important exception is that they don’t match iterators or strings. Sequence patterns support extended unpacking: [x, y, *rest] and (x, y, *rest) work similar to unpacking assignments. The name after * may also be _ , so (x, y, *_) matches a sequence of at least two items without binding the remaining items. Mapping patterns: {"bandwidth": b, "latency": l} captures the "bandwidth" and "latency" values from a dictionary. Unlike sequence patterns, extra keys are ignored. An unpacking like **rest is also supported. (But **_ would be redundant, so it is not allowed.) Subpatterns may be captured using the as keyword: case ( Point ( x1 , y1 ), Point ( x2 , y2 ) as p2 ): ... will capture the second element of the input as p2 (as long as the input is a sequence of two points) Most literals are compared by equality, however the singletons True , False and None are compared by identity. Patterns may use named constants. These must be dotted names to prevent them from being interpreted as capture variable: from enum import Enum class Color ( Enum ): RED = 'red' GREEN = 'green' BLUE = 'blue' color = Color ( input ( "Enter your choice of 'red', 'blue' or 'green': " )) match color : case Color . RED : print ( "I see red!" ) case Color . GREEN : print ( "Grass is green" ) case Color . BLUE : print ( "I'm feeling the blues :(" ) For a more detailed explanation and additional examples, you can look into PEP 636 which is written in a tutorial format. 4.8. Defining Functions ¶ We can create a function that writes the Fibonacci series to an arbitrary boundary: >>> def fib ( n ): # write Fibonacci series less than n ... """Print a Fibonacci series less than n.""" ... a , b = 0 , 1 ... while a < n : ... print ( a , end = ' ' ) ... a , b = b , a + b ... print () ... >>> # Now call the function we just defined: >>> fib ( 2000 ) 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 The keyword def introduces a function definition . It must be followed by the function name and the parenthesized list of formal parameters. The statements that form the body of the function start at the next line, and must be indented. The first statement of the function body can optionally be a string literal; this string literal is the function’s documentation string, or docstring . (More about docstrings can be found in the section Documentation Strings .) There are tools which use docstrings to automatically produce online or printed documentation, or to let the user interactively browse through code; it’s good practice to include docstrings in code that you write, so make a habit of it. The execution of a function introduces a new symbol table used for the local variables of the function. More precisely, all variable assignments in a function store the value in the local symbol table; whereas variable references first look in the local symbol table, then in the local symbol tables of enclosing functions, then in the global symbol table, and finally in the table of built-in names. Thus, global variables and variables of enclosing functions cannot be directly assigned a value within a function (unless, for global variables, named in a global statement, or, for variables of enclosing functions, named in a nonlocal statement), although they may be referenced. The actual parameters (arguments) to a function call are introduced in the local symbol table of the called function when it is called; thus, arguments are passed using call by value (where the value is always an object reference , not the value of the object). [ 1 ] When a function calls another function, or calls itself recursively, a new local symbol table is created for that call. A function definition associates the function name with the function object in the current symbol table. The interpreter recognizes the object pointed to by that name as a user-defined function. Other names can also point to that same function object and can also be used to access the function: >>> fib <function fib at 10042ed0> >>> f = fib >>> f ( 100 ) 0 1 1 2 3 5 8 13 21 34 55 89 Coming from other languages, you might object that fib is not a function but a procedure since it doesn’t return a value. In fact, even functions without a return statement do return a value, albeit a rather boring one. This value is called None (it’s a built-in name). Writing the value None is normally suppressed by the interpreter if it would be the only value written. You can see it if you really want to using print() : >>> fib ( 0 ) >>> print ( fib ( 0 )) None It is simple to write a function that returns a list of the numbers of the Fibonacci series, instead of printing it: >>> def fib2 ( n ): # return Fibonacci series up to n ... """Return a list containing the Fibonacci series up to n.""" ... result = [] ... a , b = 0 , 1 ... while a < n : ... result . append ( a ) # see below ... a , b = b , a + b ... return result ... >>> f100 = fib2 ( 100 ) # call it >>> f100 # write the result [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] This example, as usual, demonstrates some new Python features: The return statement returns with a value from a function. return without an expression argument returns None . Falling off the end of a function also returns None . The statement result.append(a) calls a method of the list object result . A method is a function that ‘belongs’ to an object and is named obj.methodname , where obj is some object (this may be an expression), and methodname is the name of a method that is defined by the object’s type. Different types define different methods. Methods of different types may have the same name without causing ambiguity. (It is possible to define your own object types and methods, using classes , see Classes ) The method append() shown in the example is defined for list objects; it adds a new element at the end of the list. In this example it is equivalent to result = result + [a] , but more efficient. 4.9. More on Defining Functions ¶ It is also possible to define functions with a variable number of arguments. There are three forms, which can be combined. 4.9.1. Default Argument Values ¶ The most useful form is to specify a default value for one or more arguments. This creates a function that can be called with fewer arguments than it is defined to allow. For example: def ask_ok ( prompt , retries = 4 , reminder = 'Please try again!' ): while True : reply = input ( prompt ) if reply in { 'y' , 'ye' , 'yes' }: return True if reply in { 'n' , 'no' , 'nop' , 'nope' }: return False retries = retries - 1 if retries < 0 : raise ValueError ( 'invalid user response' ) print ( reminder ) This function can be called in several ways: giving only the mandatory argument: ask_ok('Do you really want to quit?') giving one of the optional arguments: ask_ok('OK to overwrite the file?', 2) or even giving all arguments: ask_ok('OK to overwrite the file?', 2, 'Come on, only yes or no!') This example also introduces the in keyword. This tests whether or not a sequence contains a certain value. The default values are evaluated at the point of function definition in the defining scope, so that i = 5 def f ( arg = i ): print ( arg ) i = 6 f () will print 5 . Important warning: The default value is evaluated only once. This makes a difference when the default is a mutable object such as a list, dictionary, or instances of most classes. For example, the following function accumulates the arguments passed to it on subsequent calls: def f ( a , L = []): L . append ( a ) return L print ( f ( 1 )) print ( f ( 2 )) print ( f ( 3 )) This will print [ 1 ] [ 1 , 2 ] [ 1 , 2 , 3 ] If you don’t want the default to be shared between subsequent calls, you can write the function like this instead: def f ( a , L = None ): if L is None : L = [] L . append ( a ) return L 4.9.2. Keyword Arguments ¶ Functions can also be called using keyword arguments of the form kwarg=value . For instance, the following function: def parrot ( voltage , state = 'a stiff' , action = 'voom' , type = 'Norwegian Blue' ): print ( "-- This parrot wouldn't" , action , end = ' ' ) print ( "if you put" , voltage , "volts through it." ) print ( "-- Lovely plumage, the" , type ) print ( "-- It's" , state , "!" ) accepts one required argument ( voltage ) and three optional arguments ( state , action , and type ). This function can be called in any of the following ways: parrot ( 1000 ) # 1 positional argument parrot ( voltage = 1000 ) # 1 keyword argument parrot ( voltage = 1000000 , action = 'VOOOOOM' ) # 2 keyword arguments parrot ( action = 'VOOOOOM' , voltage = 1000000 ) # 2 keyword arguments parrot ( 'a million' , 'bereft of life' , 'jump' ) # 3 positional arguments parrot ( 'a thousand' , state = 'pushing up the daisies' ) # 1 positional, 1 keyword but all the following calls would be invalid: parrot () # required argument missing parrot ( voltage = 5.0 , 'dead' ) # non-keyword argument after a keyword argument parrot ( 110 , voltage = 220 ) # duplicate value for the same argument parrot ( actor = 'John Cleese' ) # unknown keyword argument In a function call, keyword arguments must follow positional arguments. All the keyword arguments passed must match one of the arguments accepted by the function (e.g. actor is not a valid argument for the parrot function), and their order is not important. This also includes non-optional arguments (e.g. parrot(voltage=1000) is valid too). No argument may receive a value more than once. Here’s an example that fails due to this restriction: >>> def function ( a ): ... pass ... >>> function ( 0 , a = 0 ) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : function() got multiple values for argument 'a' When a final formal parameter of the form **name is present, it receives a dictionary (see Mapping Types — dict ) containing all keyword arguments except for those corresponding to a formal parameter. This may be combined with a formal parameter of the form *name (described in the next subsection) which receives a tuple containing the positional arguments beyond the formal parameter list. ( *name must occur before **name .) For example, if we define a function like this: def cheeseshop ( kind , * arguments , ** keywords ): print ( "-- Do you have any" , kind , "?" ) print ( "-- I'm sorry, we're all out of" , kind ) for arg in arguments : print ( arg ) print ( "-" * 40 ) for kw in keywords : print ( kw , ":" , keywords [ kw ]) It could be called like this: cheeseshop ( "Limburger" , "It's very runny, sir." , "It's really very, VERY runny, sir." , shopkeeper = "Michael Palin" , client = "John Cleese" , sketch = "Cheese Shop Sketch" ) and of course it would print: -- Do you have any Limburger ? -- I'm sorry, we're all out of Limburger It's very runny, sir. It's really very, VERY runny, sir. ---------------------------------------- shopkeeper : Michael Palin client : John Cleese sketch : Cheese Shop Sketch Note that the order in which the keyword arguments are printed is guaranteed to match the order in which they were provided in the function call. 4.9.3. Special parameters ¶ By default, arguments may be passed to a Python function either by position or explicitly by keyword. For readability and performance, it makes sense to restrict the way arguments can be passed so that a developer need only look at the function definition to determine if items are passed by position, by position or keyword, or by keyword. A function definition may look like: def f(pos1, pos2, /, pos_or_kwd, *, kwd1, kwd2): ----------- ---------- ---------- | | | | Positional or keyword | | - Keyword only -- Positional only where / and * are optional. If used, these symbols indicate the kind of parameter by how the arguments may be passed to the function: positional-only, positional-or-keyword, and keyword-only. Keyword parameters are also referred to as named parameters. 4.9.3.1. Positional-or-Keyword Arguments ¶ If / and * are not present in the function definition, arguments may be passed to a function by position or by keyword. 4.9.3.2. Positional-Only Parameters ¶ Looking at this in a bit more detail, it is possible to mark certain parameters as positional-only . If positional-only , the parameters’ order matters, and the parameters cannot be passed by keyword. Positional-only parameters are placed before a / (forward-slash). The / is used to logically separate the positional-only parameters from the rest of the parameters. If there is no / in the function definition, there are no positional-only parameters. Parameters following the / may be positional-or-keyword or keyword-only . 4.9.3.3. Keyword-Only Arguments ¶ To mark parameters as keyword-only , indicating the parameters must be passed by keyword argument, place an * in the arguments list just before the first keyword-only parameter. 4.9.3.4. Function Examples ¶ Consider the following example function definitions paying close attention to the markers / and * : >>> def standard_arg ( arg ): ... print ( arg ) ... >>> def pos_only_arg ( arg , / ): ... print ( arg ) ... >>> def kwd_only_arg ( * , arg ): ... print ( arg ) ... >>> def combined_example ( pos_only , / , standard , * , kwd_only ): ... print ( pos_only , standard , kwd_only ) The first function definition, standard_arg , the most familiar form, places no restrictions on the calling convention and arguments may be passed by position or keyword: >>> standard_arg ( 2 ) 2 >>> standard_arg ( arg = 2 ) 2 The second function pos_only_arg is restricted to only use positional parameters as there is a / in the function definition: >>> pos_only_arg ( 1 ) 1 >>> pos_only_arg ( arg = 1 ) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : pos_only_arg() got some positional-only arguments passed as keyword arguments: 'arg' The third function kwd_only_arg only allows keyword arguments as indicated by a * in the function definition: >>> kwd_only_arg ( 3 ) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : kwd_only_arg() takes 0 positional arguments but 1 was given >>> kwd_only_arg ( arg = 3 ) 3 And the last uses all three calling conventions in the same function definition: >>> combined_example ( 1 , 2 , 3 ) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : combined_example() takes 2 positional arguments but 3 were given >>> combined_example ( 1 , 2 , kwd_only = 3 ) 1 2 3 >>> combined_example ( 1 , standard = 2 , kwd_only = 3 ) 1 2 3 >>> combined_example ( pos_only = 1 , standard = 2 , kwd_only = 3 ) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : combined_example() got some positional-only arguments passed as keyword arguments: 'pos_only' Finally, consider this function definition which has a potential collision between the positional argument name and **kwds which has name as a key: def foo ( name , ** kwds ): return 'name' in kwds There is no possible call that will make it return True as the keyword 'name' will always bind to the first parameter. For example: >>> foo ( 1 , ** { 'name' : 2 }) Traceback (most recent call last): File "<stdin>" , line 1 , in <module> TypeError : foo() got multiple values for argument 'name' >>> But using / (positional only arguments), it is possible since it allows name as a positional argument and 'name' as a key in the keyword arguments: >>> def foo ( name , / , ** kwds ): ... return 'name' in kwds ... >>> foo ( 1 , ** { 'name' : 2 }) True In other words, the names of positional-only parameters can be used in **kwds without ambiguity. 4.9.3.5. Recap ¶ The use case will determine which parameters to use in the function definition: def f ( pos1 , pos2 , / , pos_or_kwd , * , kwd1 , kwd2 ): As guidance: Use positional-only if you want the name of the parameters to not be available to the user. This is useful when parameter names have no real meaning, if you want to enforce the order of the arguments when the function is called or if you need to take some positional parameters and arbitrary keywords. Use keyword-only when names have meaning and the function definition is more understandable by being explicit with names or you want to prevent users relying on the position of the argument being passed. For an API, use positional-only to prevent breaking API changes if the parameter’s name is modified in the future. 4.9.4. Arbitrary Argument Lists ¶ Finally, the least frequently used option is to specify that a function can be called with an arbitrary number of arguments. These arguments will be wrapped up in a tuple (see Tuples and Sequences ). Before the variable number of arguments, zero or more normal arguments may occur. def write_multiple_items ( file , separator , * args ): file . write ( separator . join ( args )) Normally, these variadic arguments will be last in the list of formal parameters, because they scoop up all remaining input arguments that are passed to the function. Any formal parameters which occur after the *args parameter are ‘keyword-only’ arguments, meaning that they can only be used as keywords rather than positional arguments. >>> def concat ( * args , sep = "/" ): ... return sep . join ( args ) ... >>> concat ( "earth" , "mars" , "venus" ) 'earth/mars/venus' >>> concat ( "earth" , "mars" , "venus" , sep = "." ) 'earth.mars.venus' 4.9.5. Unpacking Argument Lists ¶ The reverse situation occurs when the arguments are already in a list or tuple but need to be unpacked for a function call requiring separate positional arguments. For instance, the built-in range() function expects separate start and stop arguments. If they are not available separately, write the function call with the * -operator to unpack the arguments out of a list or tuple: >>> list ( range ( 3 , 6 )) # normal call with separate arguments [3, 4, 5] >>> args = [ 3 , 6 ] >>> list ( range ( * args )) # call with arguments unpacked from a list [3, 4, 5] In the same fashion, dictionaries can deliver keyword arguments with the ** -operator: >>> def parrot ( voltage , state = 'a stiff' , action = 'voom' ): ... print ( "-- This parrot wouldn't" , action , end = ' ' ) ... print ( "if you put" , voltage , "volts through it." , end = ' ' ) ... print ( "E's" , state , "!" ) ... >>> d = { "voltage" : "four million" , "state" : "bleedin' demised" , "action" : "VOOM" } >>> parrot ( ** d ) -- This parrot wouldn't VOOM if you put four million volts through it. E's bleedin' demised ! 4.9.6. Lambda Expressions ¶ Small anonymous functions can be created with the lambda keyword. This function returns the sum of its two arguments: lambda a, b: a+b . Lambda functions can be used wherever function objects are required. They are syntactically restricted to a single expression. Semantically, they are just syntactic sugar for a normal function definition. Like nested function definitions, lambda functions can reference variables from the containing scope: >>> def make_incrementor ( n ): ... return lambda x : x + n ... >>> f = make_incrementor ( 42 ) >>> f ( 0 ) 42 >>> f ( 1 ) 43 The above example uses a lambda expression to return a function. Another use is to pass a small function as an argument. For instance, list.sort() takes a sorting key function key which can be a lambda function: >>> pairs = [( 1 , 'one' ), ( 2 , 'two' ), ( 3 , 'three' ), ( 4 , 'four' )] >>> pairs . sort ( key = lambda pair : pair [ 1 ]) >>> pairs [(4, 'four'), (1, 'one'), (3, 'three'), (2, 'two')] 4.9.7. Documentation Strings ¶ Here are some conventions about the content and formatting of documentation strings. The first line should always be a short, concise summary of the object’s purpose. For brevity, it should not explicitly state the object’s name or type, since these are available by other means (except if the name happens to be a verb describing a function’s operation). This line should begin with a capital letter and end with a period. If there are more lines in the documentation string, the second line should be blank, visually separating the summary from the rest of the description. The following lines should be one or more paragraphs describing the object’s calling conventions, its side effects, etc. The Python parser strips indentation from multi-line string literals when they serve as module, class, or function docstrings. Here is an example of a multi-line docstring: >>> def my_function (): ... """Do nothing, but document it. ... ... No, really, it doesn't do anything: ... ... >>> my_function() ... >>> ... """ ... pass ... >>> print ( my_function . __doc__ ) Do nothing, but document it. No, really, it doesn't do anything: >>> my_function() >>> 4.9.8. Function Annotations ¶ Function annotations are completely optional metadata information about the types used by user-defined functions (see PEP 3107 and PEP 484 for more information). Annotations are stored in the __annotations__ attribute of the function as a dictionary and have no effect on any other part of the function. Parameter annotations are defined by a colon after the parameter name, followed by an expression evaluating to the value of the annotation. Return annotations are defined by a literal -> , followed by an expression, between the parameter list and the colon denoting the end of the def statement. The following example has a required argument, an optional argument, and the return value annotated: >>> def f ( ham : str , eggs : str = 'eggs' ) -> str : ... print ( "Annotations:" , f . __annotations__ ) ... print ( "Arguments:" , ham , eggs ) ... return ham + ' and ' + eggs ... >>> f ( 'spam' ) Annotations: {'ham': <class 'str'>, 'return': <class 'str'>, 'eggs': <class 'str'>} Arguments: spam eggs 'spam and eggs' 4.10. Intermezzo: Coding Style ¶ Now that you are about to write longer, more complex pieces of Python, it is a good time to talk about coding style . Most languages can be written (or more concise, formatted ) in different styles; some are more readable than others. Making it easy for others to read your code is always a good idea, and adopting a nice coding style helps tremendously for that. For Python, PEP 8 has emerged as the style guide that most projects adhere to; it promotes a very readable and eye-pleasing coding style. Every Python developer should read it at some point; here are the most important points extracted for you: Use 4-space indentation, and no tabs. 4 spaces are a good compromise between small indentation (allows greater nesting depth) and large indentation (easier to read). Tabs introduce confusion, and are best left out. Wrap lines so that they don’t exceed 79 characters. This helps users with small displays and makes it possible to have several code files side-by-side on larger displays. Use blank lines to separate functions and classes, and larger blocks of code inside functions. When possible, put comments on a line of their own. Use docstrings. Use spaces around operators and after commas, but not directly inside bracketing constructs: a = f(1, 2) + g(3, 4) . Name your classes and functions consistently; the convention is to use UpperCamelCase for classes and lowercase_with_underscores for functions and methods. Always use self as the name for the first method argument (see A First Look at Classes for more on classes and methods). Don’t use fancy encodings if your code is meant to be used in international environments. Python’s default, UTF-8, or even plain ASCII work best in any case. Likewise, don’t use non-ASCII characters in identifiers if there is only the slightest chance people speaking a different language will read or maintain the code. Footnotes [ 1 ] Actually, call by object reference would be a better description, since if a mutable object is passed, the caller will see any changes the callee makes to it (items inserted into a list).

Each class value may contain any Unicode characters (except, of course, ASCII whitespace). However, when used in CSS selectors, either from JavaScript using APIs like Document.querySelector() or in CSS stylesheets, class attribute values must be valid CSS identifiers . This means that if a class attribute value is not a valid CSS identifier (for example, my?class or 1234 ) then it must be escaped before being used in a selector, either using the CSS.escape() method or manually . For this reason, it's recommended that developers choose values for class attributes that are valid CSS identifiers that don't require escaping. Description Classes allow CSS and JavaScript to select and access specific elements via the class selectors or functions like the document.getElementsByClassName() . Though the specification doesn't put requirements on the name of classes, web developers are encouraged to use names that describe the semantic purpose of the element, rather than the presentation of the element. For example, attribute to describe an attribute rather than italics , although an element of this class may be presented by italics . Semantic names remain logical even if the presentation of the page changes.

Claim open source projects. Get Started How does StackAid allocate funds? You choose the total amount you want to donate each month among all your dependencies. The subscription amount you choose is divided evenly across all your direct dependencies, but it's also shared with your indirect dependencies. That is, each of your direct dependencies automatically shares up to 5% with each of its dependencies, but they never share more than half of their original allocation. Let's use a simple example: { "dependencies": { "bootstrap": "^5.1.0", "sass": "^1.38.0" } } 1 { 2 "dependencies" : { 3 "bootstrap" : "^5.1.0" , 4 "sass" : "^1.38.0" 5 } 6 } With a StackAid subscription of $20/month, bootstrap and sass are both allocated $10/month because they split the amount. But then they share that with their dependencies. Because sass has 3 dependencies, each of those get 5% of the amount given to sass . So each sass dependency gets $0.50/mo ($6/yr) and sass is left with $8.50/mo ($102/yr). Because bootstrap has over 20 dependencies, giving them each 5% wouldn't be fair to bootstrap , so just 50% of the bootstrap allocation is divided equally among its dependencies and bootstrap keeps $5/mo ($60/yr). Here's the allocation breakdown for this example: sass/dart-sass ( 3 ) $102 /yr ├ paulmillr/chokidar $6 /yr ├ immutable-js/immutable-js $6 /yr └ 7rulnik/source-map-js $6 /yr twbs/bootstrap ( 14 ) $60 /yr ├ bundlewatch/bundlewatch $4 /yr ├ clean-css/clean-css-cli $4 /yr ├ kentcdodds/cross-env $4 /yr ├ sindresorhus/globby $4 /yr ├ karma-runner/karma-browserstack-launcher $4 /yr └ 9 more You'll notice above that sass earns $1/yr more than expected. This is because bootstrap also depends on sass so it receives an indirect dependency allocation from bootstrap . Why do we need StackAid? The problem with open source funding today isn't a lack of means or desire to support projects. The problem is decision paralysis, figuring out how much to fund each project and the mechanics of paying each one. For example, even if you have a small project, it could have a dozen dependencies and many more indirect dependencies. So if you decide to fund your direct dependencies, here are the questions you then have to answer: How much should I give to each project? How do I go about funding each project? Assuming you've figured out those questions, you might still be wondering if this is workable. Will everyone else, especially the dependencies you fund, go to this effort to fund their dependencies? Probably not. How much does it cost? Subscriptions start at $15/month. How do you make money? When you add your project dependencies, StackAid is treated as an implicit direct dependency. StackAid is on equal footing, but unlike those dependencies, StackAid's allocation is capped at 7.5%. In the example above, StackAid would receive $1.50/mo. How does StackAid figure out my dependencies? StackAid's GitHub app searches your repositories for package dependency files. For example, for JavaScript projects we look for package.json files. Is StackAid only for Node.js/npm based projects? No, you can use our GitHub action to automatically generate and publish a stackaid.json file which lists your dependencies. You can of course manually curate the list of projects you want to fund. For example, if you wanted to allocate money to the Linux kernel and Node.js, then you would add these two repositories to your stackaid.json file: { "version": 1, "dependencies": [ { "source": "https://github.com/torvalds/linux" }, { "source": "https://github.com/nodejs/node" } ] } 1 { 2 "version" : 1 , 3 "dependencies" : [ 4 { "source" : "https://github.com/torvalds/linux" } , 5 { "source" : "https://github.com/nodejs/node" } 6 ] 7 } We are working on bringing the same level of automated discovery and integration for Node.js projects to other ecosystems. Can I use StackAid without giving read access to my source? Yes, we recommend setting up a new repository that's just meant to be shared with StackAid and then use our GitHub action to automatically publish your dependencies there for discovery. How does my open source project get paid by StackAid? Owners of open source projects can claim their repositories by installing the StackAid GitHub app. As part of the claiming process, owners can associate one or more Stripe accounts with each repository they own to receive payments. Once a month the money allocated for each repository is split evenly among the associated Stripe accounts. Stripe accounts can belong to a single person or an organization that has its own rules for how the money will be put to use. Note: If your projects are not registered with StackAid, we will make every attempt possible to pay allocated funds on existing platforms such as GitHub, Open Collective, Patreon, etc. What happens when an open source project hasn't claimed their allocation? A project's allocations accumulate for 2 months. If the project is not claimed by then, an automatic reallocation happens and the amount is redistributed to the other dependencies that are claimed. Reallocation occurs on a per subscription basis. Note: During the Beta period we will not run reallocation to give projects more time to claim their funds. How do you know this model works? While it’s easy to understand how a single subscription is distributed, it’s hard to tell if this is fair and meaningful. We had the same question, so we built a simulation of 5,000 subscribers for a year. The bottom line is that the long tail is pretty fat. Popular projects do well, but StackAid funds many more projects that would otherwise get overlooked. Start funding your dependencies. Claim open source projects.

An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications .

It’s been available across browsers since ⁨May 2018⁩. Learn more See full compatibility Report feedback The export declaration is used to export values from a JavaScript module. Exported values can then be imported into other programs with the import declaration or dynamic import . The value of an imported binding is subject to change in the module that exports it — when a module updates the value of a binding that it exports, the update will be visible in its imported value. In order to use the export declaration in a source file, the file must be interpreted by the runtime as a module . In HTML, this is done by adding type="module" to the <script> tag, or by being imported by another module. Modules are automatically interpreted in strict mode . In this article Syntax Description Examples Specifications Browser compatibility See also Syntax js // Exporting declarations export let name1, name2/*, … */; // also var export const name1 = 1, name2 = 2/*, … */; // also var, let export function functionName() { /* … */ } export class ClassName { /* … */ } export function* generatorFunctionName() { /* … */ } export const { name1, name2: bar } = o; export const [ name1, name2 ] = array; // Export list export { name1, /* …, */ nameN }; export { variable1 as name1, variable2 as name2, /* …, */ nameN }; export { variable1 as "string name" }; export { name1 as default /*, … */ }; // Default exports export default expression; export default function functionName() { /* … */ } export default class ClassName { /* … */ } export default function* generatorFunctionName() { /* … */ } export default function () { /* … */ } export default class { /* … */ } export default function* () { /* … */ } // Aggregating modules export * from "module-name"; export * as name1 from "module-name"; export { name1, /* …, */ nameN } from "module-name"; export { import1 as name1, import2 as name2, /* …, */ nameN } from "module-name"; export { default, /* …, */ } from "module-name"; export { default as name1 } from "module-name"; nameN Identifier to be exported (so that it can be imported via import in another script). If you use an alias with as , the actual exported name can be specified as a string literal, which may not be a valid identifier. Description Every module can have two different types of export, named export and default export . You can have multiple named exports per module but only one default export. Each type corresponds to one of the above syntax. Named exports: js // export features declared elsewhere export { myFunction2, myVariable2 }; // export individual features (can export var, let, // const, function, class) export let myVariable = Math.sqrt(2); export function myFunction() { // … } After the export keyword, you can use let , const , and var declarations, as well as function or class declarations. You can also use the export { name1, name2 } syntax to export a list of names declared elsewhere. Note that export {} does not export an empty object — it's a no-op declaration that exports nothing (an empty name list). You cannot use export on a using or await using declaration. You can, however, export a variable that was declared elsewhere using using or await using . Doing so is still strongly discouraged, because the variable is disposed as soon as the module finishes executing, causing all importers to receive a value that's already disposed. js export using resource1 = getResource(); // SyntaxError // Allowed by syntax but discouraged using resource2 = getResource(); export { resource2 }; Export declarations are not subject to temporal dead zone rules. You can declare that the module exports X before the name X itself is declared. js export { x }; const x = 1; // This works, because `export` is only a declaration, but doesn't // utilize the value of `x`. Default exports: js // export feature declared elsewhere as default export { myFunction as default }; // This is equivalent to: export default myFunction; // export individual features as default export default function () { /* … */ } export default class { /* … */ } Note: Names for export declarations must be distinct from each other. Having exports with duplicate names or using more than one default export will result in a SyntaxError and prevent the module from being evaluated. The export default syntax allows any expression. js export default 1 + 1; As a special case, functions and classes are exported as declarations , not expressions, and these declarations can be anonymous. This means functions will be hoisted. js // Works because `foo` is a function declaration, // not a function expression foo(); export default function foo() { console.log("Hi"); } // It's still technically a declaration, but it's allowed // to be anonymous export default function () { console.log("Hi"); } Named exports are useful when you need to export several values. When importing this module, named exports must be referred to by the exact same name (optionally renaming it with as ), but the default export can be imported with any name. For example: js // file test.js const k = 12; export default k; js // some other file import m from "./test"; // note that we have the freedom to use import m instead of import k, because k was default export console.log(m); // 12 You can also rename named exports to avoid naming conflicts: js export { myFunction as function1, myVariable as variable }; You can rename a name to something that's not a valid identifier by using a string literal. For example: js export { myFunction as "my-function" }; Re-exporting / Aggregating A module can also "relay" values exported from other modules without the hassle of writing two separate import/export statements. This is often useful when creating a single module concentrating various exports from various modules (usually called a "barrel module"). This can be achieved with the "export from" syntax: js export { default as function1, function2 } from "bar.js"; Which is comparable to a combination of import and export, except that function1 and function2 do not become available inside the current module: js import { default as function1, function2 } from "bar.js"; export { function1, function2 }; Most of the "import from" syntaxes have "export from" counterparts. js export { x } from "mod"; export { x as v } from "mod"; export * as ns from "mod"; There is also export * from "mod" , although there's no import * from "mod" . This re-exports all named exports from mod as the named exports of the current module, but the default export of mod is not re-exported. If there are two wildcard exports statements that implicitly re-export the same name, neither one is re-exported. js // -- mod1.js -- export const a = 1; // -- mod2.js -- export const a = 3; // -- barrel.js -- export * from "./mod1.js"; export * from "./mod2.js"; // -- main.js -- import * as ns from "./barrel.js"; console.log(ns.a); // undefined Attempting to import the duplicate name directly will throw an error. js import { a } from "./barrel.js"; // SyntaxError: The requested module './barrel.js' contains conflicting star exports for name 'a' The following is syntactically invalid despite its import equivalent: js export DefaultExport from "bar.js"; // Invalid The correct way of doing this is to rename the export: js export { default as DefaultExport } from "bar.js"; The "export from" syntax allows the as token to be omitted, which makes the default export still re-exported as default export. js export { default, function2 } from "bar.js"; export from supports all features that import supports — for example, import attributes : js export { default } from "./data.json" with { type: "json" }; Examples Using named exports In a module my-module.js , we could include the following code: js // module "my-module.js" function cube(x) { return x * x * x; } const foo = Math.PI + Math.SQRT2; const graph = { options: { color: "white", thickness: "2px", }, draw() { console.log("From graph draw function"); }, }; export { cube, foo, graph }; Then in the top-level module included in your HTML page, we could have: js import { cube, foo, graph } from "./my-module.js"; graph.options = { color: "blue", thickness: "3px", }; graph.draw(); // Logs "From graph draw function" console.log(cube(3)); // 27 console.log(foo); // 4.555806215962888 It is important to note the following: You need to include this script in your HTML with a <script> element of type="module" , so that it gets recognized as a module and dealt with appropriately. You can't run JS modules via a file:// URL — you'll get CORS errors. You need to run it via an HTTP server. Using the default export If we want to export a single value representing an entire module, we could use a default export: js // module "cube.js" export default function cube(x) { return x * x * x; } Then, in another script, it is straightforward to import the default export: js import cube from "./cube.js"; console.log(cube(3)); // 27 Using export from Let's take an example where we have the following hierarchy: childModule1.js : exporting myFunction and myVariable childModule2.js : exporting MyClass parentModule.js : acting as an aggregator (and doing nothing else) top level module: consuming the exports of parentModule.js This is what it would look like using code snippets: js // In childModule1.js function myFunction() { console.log("Hello!"); } const myVariable = 1; export { myFunction, myVariable }; js // In childModule2.js class MyClass { constructor(x) { this.x = x; } } export { MyClass }; js // In parentModule.js // Only aggregating the exports from childModule1 and childModule2 // to re-export them export { myFunction, myVariable } from "childModule1.js"; export { MyClass } from "childModule2.js"; js // In top-level module // We can consume the exports from a single module since parentModule // "collected"/"bundled" them in a single source import { myFunction, myVariable, MyClass } from "parentModule.js"; Specifications Specification ECMAScript® 2026 Language Specification # sec-exports Browser compatibility Enable JavaScript to view this browser compatibility table.

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

Originally published at Perl Weekly 755 Hi there! Dave Cross has an article showing position of Perl on the TIOBE index. As I don't see any up-tick in new subscribers to the Perl Weekly nor do I see any increase in the MetaCPAN activity I keep track of, I doubt that the changes in the position reflects actual changes in the market. However I wonder, could the TIOBE index have an impact on the interest in Perl? How and when could we see that? Speaking of the MetaCPAN report , I'd love if someone sent a PR to the Perl Weekly that would generates same graphs using these numbers. Here is the issue for it. And another comment related to those stats. I just noticed that the No CI column went up from 30-40% to 80-90% in recent weeks. I wonder why? Is it because some changes in the way I am collecting the data or are those real changes? Is it real change? I also just noticed some negative numbers in the No VCS (%) column. That's not good. I guess I have to investigate this. Maybe during one of the Perl code reading and open source contribution events. Enjoy your week! -- Your editor: Gabor Szabo.

Perl This week in PSC (210) | 2026-01-05 The Weekly Challenge The Weekly Challenge by Mohammad Sajid Anwar will help you step out of your comfort-zone. You can even win prize money of $50 by participating in the weekly challenge. We pick one champion at the end of the month from among all of the contributors during the month, thanks to the sponsor Lance Wicks. The Weekly Challenge - 356 Welcome to a new week with a couple of fun tasks "Kolakoski Sequence" and "Who Wins". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ . RECAP - The Weekly Challenge - 355 Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Thousand Separator" and "Mountain Array" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. Mountain Separator The post demonstrates an idiomatic and compact use of Raku for typical programming challenges. It balances expressive language features with clarity, though readers unfamiliar with hyperoperators and the pipeline style might need supplemental explanation. Perl Weekly Challenge: Week 355 Technically solid, readable, and well-structured. The solutions are both correct and practical, illustrating good problem decomposition and Perl/Raku coding style. Separated Mountains Efficient and idiomatic Perl for the thousand separator using a classic unpack pattern.️ A formally defined mountain array solution with vectorised and language-diverse implementations. number formatting and sorting This is a well‑engineered, comprehensive, and professionally presented technical write‑up that goes beyond minimal solutions to showcase how to solve the Weekly Challenge across ecosystems. It favors clarity and breadth over micro‑optimizations, making it valuable for learners and polyglot developers alike. Perl Weekly Challenge 355 The solutions for Weekly Challenge #355 are technically strong, correct, and efficient. Task 2 (Mountain Array) leverages PDL for vectorized comparisons, producing a concise, single-pass check for mountain arrays while correctly handling edge cases such as plateaus and short arrays. Thousand Mountains This is technically excellent, showing a high level of Perl proficiency, algorithmic awareness, and performance consciousness. Both tasks are solved correctly, with multiple alternative implementations explored and benchmarked, demonstrating a thoughtful and professional approach rather than a "just pass the tests" mentality. Oh to live on Array Mountain… This post is a strong, well-executed multi-language technical write-up that emphasizes algorithmic reasoning, clarity of transformation, and comparative programming paradigms over minimalism or raw performance. Thousands of mountains This submission demonstrates strong problem understanding, solid algorithmic choices, and pragmatic Perl coding. The solutions are intentionally explicit, readable, and correct, favoring clarity and single-pass logic over clever one-liners. Both tasks are handled with approaches that scale reasonably and align well with Perl’s strengths. The Weekly Challenge #355 This submission is technically strong, correct, and deliberately written for clarity and maintainability rather than brevity. It reflects an experienced Perl programmer who values explicit logic, readable structure, and thorough documentation. Mountains by the Thousand This is a thoughtful, well-structured solution to both Weekly Challenge tasks, with a clear emphasis on explicit logic and state-based reasoning rather than relying on library tricks. Roger demonstrates good cross-language fluency and a solid grasp of algorithm design. Commify every mountain This post delivers clean, pragmatic, and idiomatic solutions to both tasks in The Weekly Challenge #355. It emphasizes using the right tool for the job, clarity, and efficiency over algorithmic novelty. Weekly collections NICEPERL's lists Great CPAN modules released last week .

Show Notes Matt and Phil are joined by Matthew Reinbold, director of API Ecosystems and Digital Transformations to discuss Postman's State of the API 2021 report, detailing various data points from around the API world from which specification people turn to, to how confident people feel deploying their APIs. They also discuss various topics around remote work, how APIs enable more remote work and what will happen in the next few years for APIs. Notes: Matthew on twitter: https://twitter.com/libel_vox Postman's State of the API Creators and Guests Host Mike Bifulco Cofounder and host of APIs You Won't Hate. Blogs at https://mikebifulco.com Into 🚴‍♀️, espresso ☕, looking after 🌍. ex @Stripe @Google @Microsoft What is APIs You Won't Hate? A no-nonsense (well, some-nonsense) podcast about API design & development, new features in the world of HTTP, service-orientated architecture, microservices, and probably bikes. Matt Trask: Cool. Welcome back to APS. You won't hate episode 17. I have Phil with me and we're joined by a very special guest today. Matthew Reinbold, fresh from postman, who is a director of API ecosystems and digital transformations here to talk about their report, the 2021 state of the API ecosystem. Matthew, how's it going? Matthew Reinbold: It is going. I am happy to be here first time, caller, long time listener. Is that how we say that? Matt Trask: I think that's yeah. It's how you say it. Yeah. So I mean, for those of you, like in the off chance that someone doesn't know who you are in the API ecosystem world can you give us a little bit kind of about yourself? Like you manage two different newsletters, at least as well as a pretty prolific Twitter presence as well. But if someone hasn't run into you, like. Matthew Reinbold: Well, yeah, well, first off, thanks for calling it prolific. Some people would call it annoying, but yeah, I I manage a fair number of tweets over at Twitter slash L I B E L underscore Vox, reliable Vox. That's where I talk about digital transformation and APIs and a lot of technology stuff. Occasionally. Fights with blockchain and NFT enthusiastic. But then I also manage, I also manage a newsletter called net API notes, where for almost 200 issues, going back to 2015, I've covered the landscape. I've shared essential bits of information. I've tried to boil down the, the. Current climate and get it right into just the most essential things that decision makers need to know and care about. And then I do a fair amount of blogging on a blog. That's very imaginatively named Matthew reinbold.com. In there, I talk about a fair number of things as well, but in, in, in short my passion is really about coaching people, helping people, teaching people to get better with their API ecosystem. Matt Trask: That's really cool. So one thing that kinda stuck out to me cause it's, so we're going to be talking about the 20, 21 Sidi APR report. However, I'm curious since you've been doing it now since 2015, you've been keeping notes on. The API world. How does your kind of, I hate to say this phrase, the 30,000 foot view of everything that, you know, from 2015, how does that kind of line up to what you saw with the 2021 state of the API report? Matthew Reinbold: Oh, that's interesting. So there's definitely. Maturing as a industry, we've gone through a number of phases. Those of us that have been around the block a few times, see trends come. And most often they, they tend to roll away. And over that time we have to develop models so that we can kind of. Pick the, the, the wheat from the chaff, you know, what, what are the properties of something new, some kind of buzzword, some kind of hyperbole that we can latch onto and say, yes, this is worth investing in. This is worth our interest in our effort versus, yeah, this is some marketing system, some spin as I'm looking at the 20, 21 postman report. I see. Where we've come. It's gone from being single point to point integrations. One-off bespoke API APIs to where we're now talking about things as ecosystems. We're now talking about collections of these things and how entire organizations. Manage these as, as something that's beneficial, something that's collaborative and, and managed as a separate entity rather than, than each individual unit I've got Phil here. So I have to use the forest for the trees analogy rather than just managing the individual API trees. There's now a greater awareness of what the forest, what the forest role is in the company and how to manage that. In a unique way, as opposed to the individual pieces. I will say for those that are listening, like I'm one of the things I want to highlight right up front here is that you don't have to enter an email address. It's not behind the page. We really felt strongly at postman that we had to get this information out to the most number of decision-makers so that they could make better decisions so that they could be informed as they're developing their strategies and roadmaps. So if you go to postman.com/state-of-api, you'll be able to download. With out any worry about having somebody from sales follow up with you later, or getting spam in your inbox, it's free for all. We want this information to be used. We want the dialogues to happen. We want the discourse to be rich and for me and frothy. And so please, you know, don't let past marketing spam. Stop you from checking this out. We want this in the hands of people. Phil Sturgeon: Fantastic. That's good to hear. I mean, that's I haven't got around to reading it as you might have seen from Twitter. Life has been a bit of a mess recently just spending far too much time in the field, as opposed to in the field doing APA stuff. But, yeah, that's definitely always been a concern of mine, of, you know, you hear about these white papers and reports and you just know so many of them like should have just be in the blog post, but instead that like a PDF that and you've got to enter information and then you just get like that fifth email, like, why didn't you reply to my previous four? I was like, I don't know who you are. I just want to read this thing. So yeah, I'm glad you folks are going in a different direction, but Maybe just taking a step back. Like, what is the state of API is report all about where are you getting your information from? What sort of research is being done? And what's the hospital. Matthew Reinbold: Great question. So this is, as far as I know, the largest survey of its kind, we had more than 28,000 people respond to our latest in a series. What we tend to do is try and track where the industry is at. And typically that's been around certain areas. Like how much time do you spend developing API APIs? What kind of tools are you using? Really good stuff there tracking the growth of, of the industry and the maturation of the industry. What I brought to the table this year. Was an interest on finding the behaviors that lead to sustainable, healthy API ecosystems. Like so much of what we talk about when it comes to API ecosystems is still very anecdotal. We tell stories about the Bezos Amazon memo, where we talk about like Twilio or Stripe, but when it comes to decision makers in large organizations, they're still. Trying to pull at what are decent KPIs, what are the behaviors I should be grooming or promoting within my company to make sure that I can keep producing quality API experiences again and again and again. And so what we did with this report that I'm really proud of is dig deep and discover, like, what are the correlating behaviors in organizations that lead to good things happening for companies? Phil Sturgeon: Okay. That's interesting. Cause I think. There's always this question around, like, what's a good API and what's a bad API. Right. And that's just such a nebulous, almost pointless topic so often, because you're just going to end up with opinions about camel case versus kebab case and opinions about rest versus graph UI, and all the nonsense that we love to fight about. And there's going to be someone with a fever at HTTP status code. And none of that actually matters, but you're talking about more of the business level stuff or what, what sort of things have come up as like. Really interesting results from, from your survey about how to build a good API what's what's, what's new and what's interesting. Matthew Reinbold: Right. Well, one of the things I wanted to look at was some of the insights that popped out to me when I was reading accelerate. So accelerate is like from. The previous decade, but it was written by Nicole Forsgren, Jess humble, Jean Kim, they came together and tried to figure out like, what was it about dev ops? That was so powerful. And they wanted to do it in a, in a way that quantified things, not just like, Hey, this is awesome. You should be doing it, but like get to the meat and potatoes of why is this powerful and why should businesses adopt dev ops? And as they went through their research they ended up discovering that there was really four things, four metrics that showed how dev. Made for better organizational performance. And those things were lead time, deployment, frequency, meantime to restore, or how quickly you recover and the change fail percentage. And I thought, huh, that's really interesting. Now that's for dev ops, but if these things are so instrumental in having organizations outperform. Their peers. Can we find the same correlation with API APIs? If we have the same behaviors, can we therefore then draw a line and say, if you have these things, if you have positive aspects of these four attributes, can you then have a more sustainable, more powerful API program? And based on our survey results, the answer is yes. So I can, I can go in and how we, how we drew that correlation. Phil Sturgeon: I'm curious, what sort of metrics are We, looking at? Matthew Reinbold: yeah. So first off we asked people on a 10 point scale. What, how, how well do you think that you've become API first? So out of our 28,000 respondents, they looked at this 10 point scale and they, they put themselves, you know, how they felt approximately 8% of the people that responded said, yes, we are either a nine or a 10 on the scale for API first, we said fine. And then we went through and we said, okay, you know, how long does it take you to make an API? Are we talking hours, days, weeks, so on and so forth. And we also said, okay, you know, not just time to produce, but how frequently you deploy and how many times do you have a deployment failure? Meaning like you put something in production, but it didn't work. Right. So you have to roll back and then like, what was your time to recovery? Like when an outage does occur and let's be. And outage always occurs at some point. Like how, how quickly can you recover from those things? So we got these nice, you know, bell curves and everybody kind of clumped toward the center on these things. And then we said, okay, Now the magic is we go back to that first question, the people that say their API first that have some kind of strong belief that they're doing API first, let's see how they compare to their peers on these metrics. And again, and again, all for these items, API, first people perform better. So, you know, taking one example here. API first people were able to deploy 17% faster than their peers and you know, in a day or less. So if you are API first and granted, there, there might be some subtlety in how a company defines that. But bottom line, if you are API first, you perform better on these metrics than your counterparts. Phil Sturgeon: Interesting. And yeah. Seeing, seeing as you raised it, what is API first? There's, there's a lot of different definitions floating around. Right. And so just for listeners that might not have listened to everything we've ever talked about and read every blog post we've ever read ref ever wrote how do you define it? Matthew Reinbold: Sure. Well, first for people that haven't heard this and haven't listened to every episode, shame on you. Second, I define I defined API first and. Making the API experience or the interface, the primary means for the functionality exchange. So not viewing, like I'm going to create this functionality and then subsequently go and some other team or, or some other project we'll be wrapping this thing in an API. It's thinking of creating an API experience as the primary exchange mechanism with dysfunctional. Not a library, not a module, not a class, the API. So this is slightly different than API design first, which is, I am going to subsequently talk to stakeholders, create a model, whether that's in an open API document or some other means, but I'm going to sketch that out. Test my assumptions, and then subsequently only begin code after. That's API design. First, I do draw a line between those two. They are very copacetic. They, they work together like peanut butter and chocolate, but there, there is a difference. You can, you can do API first without necessarily being API design first. Phil Sturgeon: For sure. Oh, well, we've got you on a roll. You're doing these really well. What is API as a product? Matthew Reinbold: Ooh, API API as a product. So that is creating an API with the. Awareness that it will have a roadmap. It will have ownership beyond just being put into a production environment that it will grow and change and subsequently necessitates the kind of modeling responsibilities and, and awareness that it will be growing and changing over time. Phil Sturgeon: Okay. So instead of, yeah, API first is your product should have an API. And that will be managed by the team who was making this product. And API as a product is a slight variant of API. First, that kind of takes that API out of that generic functionality team and says the API itself is the product. And another team potentially on the same team will be making a product using that Matthew Reinbold: Right. I, I would, I would, I would venture there's a lot of large enterprise environments for which API for. It's about a project that gets the thing into production. And then that thing is left to operate and run on its own. Perhaps there's some monitoring, perhaps some observability, but the actual team that made it is off doing the next thing and the next thing and the next thing there's not the idea that. This is a long lived item that, that produces some kind of business functionality value that is competing in a complex dynamic marketplace like that. That's the API product side of the house. Phil Sturgeon: Hm. Matt Trask: So the, I guess like the, the big question to bring up, I think right now is what did the pandemic do for the API ecosystem? Matthew Reinbold: Well, you know, first of all, I want to just stress that, that this thing that we kind of hand wave is the pandemic was actually like multiple congenital. Crises all at once. Right. You know, I, I want to, for the audience, like we're talking social unrest and political upheaval and supply chain disruption, and the, the pandemic was really a catch all for a tremendous amount of business stress. And what we've seen in the report is the usage of APIs, the number of API APIs the. Amount of focus and care on API. APIs has increased tremendously with that pandemic because business leaders, technology leaders are struggling with this amount of change, this amount of disruption. And so having architectures that are slow to change, difficult to change is just not cutting it in this. Set of multiple crises. So any kind of architectural advantage that allows them to change rapidly change quickly to do different things with how their development investment is deployed. So, you know, for example, taking that one dev team that was altogether in the office and being able to break it down into microservices to allow for greater asynchronous operation, greater flexibility. Those are the architectures that are being sought right now. Matt Trask: Yeah, that makes sense. I mean, it always here in America, I don't know if it feels sing, but you know, like there's. At the core level there. So like the whole, did we go back to the office and be Sandy the office upheaval as well. So it makes sense that there is kind of like a, a struggle on rapping, like getting non-technical CEOs, CTOs, CFOs their heads around the game-changing, this of APIs that doesn't surprise me at all to hear that they're still kind of, I don't want to say struggling, but unsure. Maybe like, Matthew Reinbold: Well, and, and, well, I, I think that's an interesting perspective because it assumes that leaders were in command and control positions of how the labor was divided anyway. And I would actually, I would actually posit that it's the opposite. It was everybody immediately going and running to their home offices and working in a remote work environment. The change in the communication paths changed the architectures that were subsequently produced by those teams. It's Conway's law in effect. And therefore, as we, as we look forward, as we look forward to what's going to happen, I would, I would venture that the organizations that pull people back to centralized locations, for whatever reason, I'm not going to debate whether that's good or bad, but the people that pull the development teams back to. see, like the Terminator two bad guy they'll reform remold because there will be more efficient communication patterns when everybody's face to face. Whereas those organizations that continue to have a distributed workforce will have more distributed architectural patterns because that's how communication is happening. Phil Sturgeon: That's really interesting. I haven't really thought about it before, but I, I, I bet there's been an uptick in kind of API design first, specifically due to this as well. Right? Because my experience working we work was, was pretty awful as far as like API planning goes and as a result, APA architecture and API performance and Matthew Reinbold: You don't say you should blog about that. Fail. Matt Trask: Yeah. Phil Sturgeon: 25. I'm going to do a book about that shit. Matt Trask: Have you tweeted about this yet? Phil? I'm not sure if anyone knows your true Phil Sturgeon: I did a talk. I did a talk recently. But yeah, there was, there was such an element of like, we're real in an open plan office, playing ping pong together and shooting each other with nerves that there was never any effort on API contract being written down in any shape or form because you're all sitting about. And you're just like, what's that end point? Cool mate. Oh, if slash whatever. Oh, is that a, is that property of booty? It's a string called true with QuoteWerks and then you didn't have a need to write it down because you just show it over, over the top of Nerf fire. And I, I do wonder if remote work, well, not necessarily remote work, but quarantine remote work has helped push people more towards it because if you can all be sitting around asking each other, you're going to be typing. The contract over slack. And if you're going to be typing it out over slack, which is inherently ephemeral, then you might as well type it into a Yammel file and commit that in the repo. And then you can have design reviews around the board request or other tools that the offer, that sort of thing. So, yeah, that's, that's just completely a hypothetical and something I'm thinking the second night and check that, but I'm sure it's happening. Matthew Reinbold: I completely agree. And, and let me throw in something that's not in the report, but something that's got me totally geeked out and I'm watching for on my radar, we are going to see the greatest Renaissance of API design documentation that we've ever seen in the next couple of years. Now, granted, you know, as far as Renaissance goes, maybe Renaissance. Documentation are not that great. So, you know, let's put the party hats back in the closet, but what we're seeing with the great resignation right now is all of that knowledge that people acquired in their heads is leaving. It's headed out the door and I've read reports like up to 80% of how to do things with API APIs is in people's heads. Like at we work. If you needed to know how API has worked. You know, you knew Phil was the guy that could get you straightened and Phil Sturgeon: I didn't have a clue. That was the problem. I was trying to find out how to do it. Matthew Reinbold: Okay. So I wasn't, it was somebody, it was somebody on the other end of a, of a Nerf battle away Phil Sturgeon: Someone who quit already is the person that you. Matthew Reinbold: But right now in organizations like you have this phenomenon where a tremendous number of people are leaving organizations and they might've been the sole person who knew where the end points were or knew how that particular tricky function worked. And as organizations are trying to deal with this and recover and still be productive, there's going to be a greater emphasis on having that crap written down, having things documented. Organizations don't have aren't left on their back foot like they are right now. So whether that's heavy handed processes, whether that's just a greater appreciation for documentation among the staff, that's left, whatever that manifests as there's going to be an increasing amount of emphasis on documentation, because people have seen that too much was stuck in people's heads and it's not sustained. Phil Sturgeon: Yeah, that's a really good point. I mean, and not just kind of documentation, but the whole open API as a source of truth earlier on. And I figured it has to be, has to become more noticeably important when Yeah. They've, they've lost the whole team. How the API works and you know what it's like, code's always a bloody mess. Cause you just hacked up within about what over the place and patch things and fix things. And what about and yeah, when they find themselves rewrite in the API, cause no one can really take it over and no one remembers how it works and there's no documentation for it. And it's just too hard to figure out when they just make a brand new one. And they have a whole brand new team doing it. Cause they've already lost all that stuff. Matthew Reinbold: Yeah. Phil Sturgeon: That's a situation that a lot of managers and business people are going to say, how can we go about avoiding doing this? And I just hope there's someone in the room that says, well, APA designed first would really help avoid this problem because otherwise they'll just repeat all the same mistakes again. Matthew Reinbold: Right. Absolutely. Whether it's design first or tools that help analyze existing traffic and write the document afterwards, like whatever you got to do, get that written down and start taking some notes against it because. It's it, I believe right now with the great resignation. It's an Achilles heel. That's probably hampering a lot of organizational ecosystems right now. Matt Trask: Yeah, I would definitely agree. I mean, it shows in the report under open API three dot oh, 44% of people are aware of it, but they don't use it 28% say they use it. 12% said they use it, the love it. So even just combining use it and use it in love. It still does not match aware of we're not using it. Which means that there is definitely a. A river to jump over. So to speak, to getting more people on, to open API, which is probably currently like the standard for API documentation right now which comes back to your point, which allows them to start writing things down and start documenting things. And Phil gets it by bus tomorrow. We work is still going to be okay. It very well could happen. Which is exactly why I use that example. And it, it, yeah, it it'll give the organization a little bit more or a little less reliance on what's in people's heads a little bit more stability in case great races, nation three Datto happens in three years. You know, you don't know what's gonna happen. Phil Sturgeon: Is that when everyone resigns from web three point now, Matt Trask: please. Don't don't threaten me with a good time. Like I've already, I've already muted those web three and NFD on my Twitter and it cleaned it up so Phil Sturgeon: Why do you hate progress, man? Matt Trask: A lot of reasons. I'm a combustion at heart? No. Matthew Reinbold: Hey, if you don't, Phil Sturgeon: particular messages of this progress that are the problem. Matthew Reinbold: if you, don't stand for something, you'll fall for anything. Good for you, Matt. Matt Trask: yes, I've always wanted my life to be attributed to a, a Hamilton quote. So I am glad I did. I can check that one off to get back onto the actual topic and not just bashing NFTs for an hour and a half, which sounds like a lot of fun. What you the most about this report? Like what was something that you read that just you weren't expecting? Matthew Reinbold: I, I think there was two things that when you combine them together it made me tilt my head and go, huh? The, the first is that more than anything else? Including speed to production. People want quality API APIs. They want stability. They want some other things reliability. But the primary thing that people want out of their, their API APIs is quality. And yet when it came to whether or not people had time to test. Everybody acknowledged that testing was good. Tested was valid, but nobody had enough time for testing and it's like, huh? These two things kind of seem like. The, the two sides of a coin, right. You know, people aren't getting the quality that they want, but everybody acknowledges that they don't have enough time to do testing, even though they recognize the testing is an extremely valuable type thing. So I think when it comes to socializing this report and talking to decision-makers and doing the kind of coaching that I so often do, I, this is one of those things too, to bring up, like how in your program are you supporting. Testing and ensuring that enough is being done there so that your developers feel like you're, you're reaching the kind of quality goals that, that you're, you're promising to the rest of the world. Phil Sturgeon: Hm, do you, is the survey broken down by role? So can you, can you look to see if. Managers and engineers have a rule, very interested in, in high quality. And engineers are going, but we don't have enough time, but the manager's like, oh, they definitely have enough time. Matthew Reinbold: Right. So we do have a breakdown by role and job title, but I don't have the numbers in front of me that, that combined, and show me how to break down the quality question. Phil Sturgeon: Yeah, that'd be an interesting one. Cause yeah, so many roles, so many organizations, I just take it as like a universal truth is that companies are just, you know, business and product are demanding feature, feature, feature, feature, feature, and engineers are just like screaming, just keyboards on fire, trying to try to hit them goals. And everything's just wonky as hell. And it seems to be everywhere I go. There's not enough to have. There's not enough time for QA. They might've got rid of the QA team because it's slowed down product and slowed down delivery of features. Yeah, everyone wants high-quality API has, but no one wants to put the time in to testing because testing is inherently hard and slow. Matthew Reinbold: Right. And kind of along those same lines, another stat that jumped out at me was that 76% of the people building API APIs have less than five years experience doing. I mean, you know, as far as restful APIs now, we're, we're more than a decade into that journey. So that stat leaps out at me, like what is it about API development, where we're getting people with zero to five years experience like what's happening. There are the successful API builders, aging out and becoming management. it, are they moving on to web three O and NFTs? Like, like what is, where are our experienced API builders and why are these critical pieces of business infrastructure? In the hands of relatively younger people. That's not to say that they can't be doing a good job, that, that it's impossible to build a great web experience at your first time at bat. But it's also something where I think everybody on this call would probably agree. Experience counts, experience matters. Ha being around the block once or twice, you pick up a feel for what's beneficial, what's maybe a little wonky and you can imbue that into a better design at launch. So, you know, where are the. 10 year, the 12 year, the 15 year veterans. And why are they not the primary source of API infrastructure development? Phil Sturgeon: Yeah. Some that I've seen so much, again, just, I love complaining about we work. Pretty much everyone that was a junior developer, Right. Like the vast majority, what, what you need developers and their role responsible for creating you know, there's like a hundred API APIs and, you know more than a hundred junior developers with just a sprinkling of seniors who were more on the cowboy coder end of things. Not, not to be rude, you know, like startup, you need to be super agile, super fast, not, not a perfectionist. And so, so many of the problems where this is, this person's first rails app, like they know how to accept incoming Jason parameters and they know how to spit something back from the database. And. That's that, and they know how to make a web request. So he talks to . He talks to F talks to G in the thread, and then no, one's got a timer anyway. So everything falls over, like, things like that. The sort of thing you realize, if you've been doing APIs for five years, or for 10 years, you've been doing it for 10 years, you wouldn't do that. You just wouldn't do that. You'd put something in a sidekick job and then implement a web socket or a web hook, or literally anything else. But. That's the sort of thing you do when you consider like HTP failures or server downtime, to be an edge case that is like some weird scenario that probably won't happen. And when you've been doing it for a longer time, you're like you, you change your mindset to this web requests probably won't work. And on the off chance that it. This is what should happen. And you just get really defensive and paranoid and have like 25 different guard statements and, you know, 25 different types of ex exception catching and, and every single circuit breaker and trigger warning that you can possibly put on this thing. And there is, yeah, there is a change in mind. Around around that kind of it doesn't, I'm not being a gatekeeper or at least they're saying you've got to be doing EPS for 10 years until you're good. But when you start out, you you're such, you're more of an optimist. You haven't seen it go wrong in as many ways. You haven't had cascading failures and you haven't had all these terrifying things that happen. So that, that is definitely a concern for me is that I think, yeah. Happy, happy path development. When you go from having one AP. To having 20 or a hundred, the, the the chance of straying off the happy path gets exponentially worse. Right. And, and that's just something, I think a lot of these younger developers on experience with. Matthew Reinbold: Right. Even, even when it comes to design, having used API APIs, having to incorporate the API APIs, you better understand what makes a good description and what is just a reiteration of the, the name itself. Yeah. Yeah. If I have a field called date of birth and the description is just the birth, that, the date that the person was born on, like, well, what was the. do I need to refresh it? Or is it cashed? You know, like, can I store it or is it part of some kind of regulatory PII? And I shouldn't, you know, I can use it, but I shouldn't store, like, there's so many issues that once you've been down that road, and then you're asked to produce an API, you bring that experience with you and you put it into the description that adds so much that yeah. I, I, I, I don't know. How we continue to get that, that experience circulating and get that in front of people. But I think it's really important. Matt Trask: Well, I must wonder too, like how many of those, like experienced API builders are getting swallowed up into Stripe? Twilio, Google. And kind of almost locked away working on their API APIs and not able to share their experiences down the road to junior developers in their own companies or interim networks, things like that too, because it feels like you do your five, seven years as developer, you get pulled into the management game and then all of your knowledge is still there, but you're having to balance both managing a development team, hitting your goals. Pushing out products because you've got to make money for the business. And all of your knowledge that you've worked so hard to gain is kind of sidelined in the name of profits or KPIs or whatever it might be. Matthew Reinbold: Possibly there's, there's certainly exceptions that spring to mind. One of which is Tim Burks and the team over at Google and with the number of resources that they put out there. For their APIs. It's, it's kind of a mouthful, but if you do a Google search for that, they've produced a tremendous amount of documentation about how they support API APIs at scale, how they do their design reviews, how they think about consistency and cohesion across their entire footprint. So that certainly what you described could be the case in some places. You know, I, I, I do think that it's not necessarily the default that's people go off to these big organizations and then just disappear because the folks at Google around Tim and his crew they're doing some great work. Phil Sturgeon: So I've been sat in the room with you having these sort of conversations your last job, Right, Like a center of excellence type stuff. You, you get a bunch of smart people and me together and start talking about what, what would help with these various different problems? Like how do we do APA design reviews? How do we do governance? What standards should we be interested in? So I think sometimes yeah. Experienced developers can get sucked up into these companies and kind of finish and end up having that scale was used for something else. But I, I think companies that have those governance processes, like they're sharing their experience back by creating style guides, by creating programs that they explain how these, how these like API designed life cycles or API life cycle should work. And that's a way that they can essentially. Distribute their experience. So instead of like, I know what to look for when I'm reviewing a poor request, they can create a style guide. That means that everyone will do that. I think the danger there is that when style goes focus on what, instead of why then, then you kind of lose some of that experience because it just seems like arbitrary decisions delivered from upon high. Right. You just get. Do it this way, but, but Y I've read loads of style guides recently. And, and some of them, I should probably show the examples. It's just like, do this. Like, why you don't tell me what to do? You don't my dad, like, it just, I couldn't figure out what they possibly could have meant by it. Cause usually I can look at something. Why might they mean that? Oh, that reminds me of a thing that happened along these lines. They probably got burned by that before, and they want to avoid it, but if you don't see why it just sounds arbitrary and you're not actually teaching anyone on anything, but if you do it right. that that can be really helpful. Matthew Reinbold: Right. And it's also essential that if you're designing these systems like a governance or like a center of excellence that you have the feedback process that you have, the, the communication cycles so that when people do have that kind of. That they have a recourse. It's not a dead end. It's not either you do this or you're punished for it, but oh, if this doesn't make sense, here's who you talk to. Here's how you can escalate your concern here is how you elevate your edge case. And we can have a discussion about it and you can help co-evolve this thing, because you own this as much as somebody else, the, the phenomenon that you described, where it's a dead end. It's thrust upon you. You don't have ownership of that. And as a developer, that does not feel good, that does not invest you in seeing the long-term growth of, of that system. You want to burn that system. You want to be the rebels flying through the death star trench. You want to take that thing down? So what's essential is to realize. You provide the avenues for people to, to voice their concerns, voice their questions, and make them feel heard in such a way that their process, the process is theirs. It's not something done to them. It's it's their process. Phil Sturgeon: I'm just laughing about the death star rebel situation. Now I'm completely distracted. I need to go rewatch some star wars. I don't know. Matt Trask: I mean, your, your thought on the ownership thing is also interesting cause And we like watching the junior Twitter, the junior developer Twitter circles, which is not the end all be all of it all, but there is a large emphasis on if you want to make more money, you need to jump ship every two years on average. And that kind of removes the does or not the desire, but like the, the ownership of any sort of product from a junior developer, because in two years, they're going to be onto another thing. They're going to be onto another system. Codebase, maybe another language and it, it does kind of bring back, like, how do you entice people to have ownership, even if they only are going to plan to say somewhere for a short period? Because we all know that like having, like you said, having that ownership is going to kind of make you more invested, more caring, more thoughtful, more empathetic towards whatever it is that you're building. Matthew Reinbold: Right. I mean, we're veering into management territory, which I'm happy to talk about. I, I know. Matt Trask: very allergic to management. So. Matthew Reinbold: But I, I was just reading Harvard business review. Hey, I'm fun at parties too. So I was reading Harvard business review talking about COVID and the great resignation and the, the management challenges that, that come with that and what we need more. In all companies is a feeling of belonging, a feeling like we have a career progression feeling like our, our, our work has impact and all too often management, just as about making sure people don't do dumpster. Right. You know, I'm, I'm here to police you because the organization doesn't trust you. And it leads to all kinds of weird effects. Like, Hey, if you actually want to grow your career, you need to leave. You need to hop companies every two years and let's be clear that may work, but it's still very disruptive, not just for the company, but for the individual. 'cause they're having to rebuild all of those social structures, their relationships, their patterns, the routines it, it's not, it doesn't come for free. And so from a management standpoint, if you can show people how to have that fulfilling career, how to fulfill those needs. They don't have to jump ship every two years. There's no reason that that has to be the default blueprint. And from a company standpoint, you actually benefit from that accrued experience rather than having a developer. That's done the same thing. Five times you get five years of experience. That's really powerful, really tremendous. And that, that ultimately not only leads to better APIs, but leads to a better employee. So there is a disconnect we need to work with our management layers. It shouldn't just be the technician that has some headcount is by default manager. There needs to be an appreciation for how those are unique skill sets. Those are unique muscles that need to be exercised, but. If we can create that fulfilling sense of duty then, and that the career path for these individuals, we can get them off of this kind of binge and purge career treadmill. Matt Trask: So that's a really, yeah, that's a really good way to put the whole two year turn. And I mean, it comes back full circle to what you just said earlier, which is, you know, 75% of API has been developed now or done by people with less than five years experience. And that's probably because of the same, people are jumping, jumping, jumping. Whereas if you can keep them around, make them happy, make them feel like they belong. We might actually start seeing that number. Dropped significantly to more experienced API developers building more thoughtful API design with, with years of knowledge built up. So I think it'll be really interesting to see kind of what happens with this great resignation how that all shapes up. And then it'll be interesting to see to kind of the 2022 say the API report. How does that. How, how will things change from a year in a year going forward? And what can we expect possibly looking at these two years, the next five years after that, the next 10 years growing on different trends, you know, we might see NFTs ruling the world. We might see graph QL. Rolling. Phil Sturgeon: No comment. Matt Trask: Matthew is kind of shrugging Phil Sturgeon: we're all sad. Now, rural sat now, NFTs powered by graft UL, problem solved. Can you, can you still right click that? No, you can't. It's like a post. So. Matt Trask: Well, there goes Matthew Reinbold: Each unique query is published as an innovator. And you can put the ownership of that query in a blockchain so that you don't have the centralized point of failure. Phil Sturgeon: I was going to thank you for being for, for making this podcast sound intelligent for once. And, Matthew Reinbold: And then I ruined it. Sorry. Phil Sturgeon: and then you. Matt Trask: no, no, no, you didn't ruin it. You just brought it back down to its normal level of ridiculousness. Phil Sturgeon: Fantastic. No. Do you have any predictions for what we're going to see in the, in next year's state of this report? Because then we can play that clip back and laugh at how wrong you were. Matthew Reinbold: Oh, lovely. All right, well, let me have a few minutes to sandbag my answer. No, I think there's a tremendous amount of, of areas where we can take this correlation that I talked about before behaviors. You know how the question immediately becomes well, okay. If these four behaviors are so good and are present in high-performing API companies, how do we get there? And this year we had a little bit around leadership and what leaders do. To get an API first company. I think there is a lot of exploration we can do there to really dial in and say, okay, we know these things are good. How do you get there? How do you promote these things? How do you, how do you get it so that you are able to deploy in a minimal amount of time or recover faster? What are leaders in those organizations doing? That's one of the things I'd love to dig into obviously. A lot of post pandemic aftermath. There's been a tremendous amount of published about how this digital transformation and, you know, we're so much more flexible and adaptable because we, we are now doing all our conversations over zoom. And I look at that and I, I scratch my head because. Digital transformation, at least in the non buzzword compliant way is a whole lot more difficult than just moving everything to a slack conversation or a, or a zoom conversation. Like it means fundamentally dismantling your policies and procedures and reinventing them in a way that digital technology lends itself to. So figuring out what that post pandemic landscape looks like and how we're still feeling the knock on effect. Is going to be something that's also going to be very interesting to explore. Matt Trask: Yeah, that's definitely true. I mean, I think one thing I would like to see is, is that number of people who know open API, but don't use it start to gradually shift down and people who are using open. Start to shift up, which, you know, from a silver right back to having documentation and some sort of notes about their API. So when the, the knowledge people do eventually leave because everyone leaves the company at some point, the knowledge isn't necessarily leaving. And instead we're, we're kind of leaving a better legacy to the people following us. Yeah, definitely. Matthew Reinbold: Here here. Matt Trask: Cool. Matthew, thank you so much for taking some time out of your, your, your day to talk to us. We really appreciate it. Look forward to having you back in roughly a year's time to talk 20, 22. Say the API report Matthew Reinbold: I love it. Let's do it. Pencil it in right now. Matt Trask: Yep. It's it's on my calendar. I don't know what I'll be doing in a year from today, but I know for a fact we'll be talking again. If you want to get. Matthew on Twitter. He is at libel Vox, L I B E L underscore V O X M. And we'll throw the link to your blog and Twitter in the show notes as well as everything else. Awesome. Cool. Thank you so much. We appreciate it. Phil Sturgeon: Yeah.

Report Abuse Amara Graham Posted on Jul 17, 2019           Following Cooking Recipes Makes You a Clearer Writer # devrel # documentation I'm really into cooking, baking, pickling, really anything that will end in me eating something delicious. But I didn't find it enjoyable or "get good" at cooking overnight. My parents cooked most of our meals and if you planned on eating said meal, you were required to provide some amount of assistance, regardless of your blood relation to the family. After graduating out of dorm life I realized I needed to feed myself or starve, so I started getting bolder with my kitchen experiments and I'm pleased to say I'm still alive. "Ok Amara, but where is the tech components of this blog?" Hold on, I'm setting up the metaphor. "Ok fine." In the Kitchen If you stand in a kitchen and watch my dad cook - he reads a recipe, studies it, then goes through and pulls out all the things he needs to make it happen. For banana bread he usually has to pull the frozen bananas out early to thaw them enough to peel them, he portions out the spices so he can toss them in while mixing, he sprays the loaf pan before the mixture is together. If you watched me in my first apartment attempting banana bread for the first time, you would have seen someone who barely read the recipe (I've made this before, with supervision, and watched my dad make it for years, how hard can it be?) and did exactly every step of the instruction in series. Pull frozen bananas out of the freezer, immediately realize you can't peel a banana when its extra frozen, wait just long enough you can pry the peel off, smash the mostly still frozen bananas, slowly add each spice one at a time, measuring as you go, mix everything together, spray the pan, realize the oven isn't on, wait to pre-heat, blah blah blah, why did this take double the prep time? My dad has always taken the methodical approach to everything, he's a chemist and he loves math. I'm impatient and can't spend even 30 seconds idle when I know I need to complete a task, so I pretty much have the attention span of a Border Collie (have you seen those dogs stare at a ball, full body shaking with excitement?). At My Desk I'm sure you'll be shocked to hear when I sit down to learn some kind of new tech, I barely skim the tutorial or docs, immediately start the "doing", and often end up frustrated and annoyed with the experience. In some cases I tell myself things like "oh I've used an API like this before, I can just make it work" and 3 days later I'm banging my head on the keyboard. "Amara, just slow down and actually read the tutorial." Easier said than done. Not just for me personally, but for any dev, and that includes your dev coworkers, customers, community, etc. Time is precious, workplaces are more agile than ever, and people pay money for other people to stand in line for them. In My Brain Now recipes, just like tutorials, can be poorly written, but even the good ones can suffer from poor execution as I rambled on above. There are 5 things I learned from getting better at following cooking recipes that I think apply to written technical content. Ambiguous Terms Jargon Chunking Brevity Audience Let's take a look at each one. Ambiguous Terms Have you ever read a recipe, seen the word "mix" and go... with a spoon? A stand mixer? How long? Or how about "hand mix"? Did you know that a 'Hand Mixer' is an appliance and not the things at the end of your arms? Because a few years ago when we first started dating, my now husband did not. In tech, we love using the same term for a number of different things. Or we have a number of different words for the same thing. Really friendly to beginners right? Something like "Run this" might make sense to you, the engineer who built it, because its probably never crossed your mind that you run it globally and not in a particular directory (or vice versa) but that can be one of the most irritating things for a dev struggling with the worry of doing something wrong and/or irreversible. Be explicit in your use of terms and maybe consider a glossary of terms relevant to your project/product/industry/company. What does this mean in this context, right here, right now? Don't leave your reading punching out to search for answers. Jargon Every talk I've given on AI to beginners has included a disclaimer about not only ambiguous terminology but jargon. 'Fine-tuning' is not super intuitive, neither is 'hyperparameter'. 'Fold in' or 'soft peaks' in cooking is right up there too. Mastering the jargon can disrupt retention of fundamental topics. Explaining these terms early in docs and tutorials is crucial. You should not assume knowledge of jargon, so this is another +1 for a glossary. Chunking I am a huge fan of multi-part tutorials and how-to series, so long as they are done right. At the end of each part in a series, you should have a small complete something. Developers may not have time to sit down and do a 3-6 hour tutorial, but they should be able to get 20 minutes to an hour of uninterrupted time. You don't want to tackle a slow cooker recipe at 5pm expecting to eat it for dinner, but you may want to brown some meat so it is ready to toss in the next morning. If I have 20 minutes today to set myself up for success later today or tomorrow, I need to know I can get it done in the allocated time. And I need to feel like I can pick it up again without rereading the entire thing. Brevity Unlike this blog which is probably way too long for most of you, the more concise your written technical content the easier its going to be to follow. It's part of what makes the Tasty videos so appealing to watch - someone makes a sped up, top-down recipe that feels fast and easy even if its neither. This doesn't mean you can't write an introduction or a conclusion that goes more in depth about the content, but when you get to the meat of the docs or tutorial it should be a lean, mean, executing machine. Food bloggers are great at this, they may give you step-by-step pictures and commentary, but they almost always include the recipe separately. So feel free to tell me how you are going to save the world with this tutorial, but keep it out of the exact steps I'm following so I don't get overwhelmed. Audience This is maybe the most important, although I could argue that they all are. Knowing your developer audience is extremely important in technical writing. This helps you make decisions about what languages and references to use, what their workstation may look like, and maybe even things like their attention span. If your audience is students, whether they will admit it or not, they tend to have WAY more time to sit down and really study a tutorial. Or maybe they are participating in a hackathon and it just needs to work as fast as possible. But maybe your audience is enterprise developers, like mine often is. This means it has to be production-ready, maintainable, and even trainable across teams. Your maintenance team may be entirely separate from your product engineering team, so the content they follow may need to be different. Knowing or identifying your audience can be challenging, but this is a great opportunity for your devrel team to really shine. Celebrate Those Incremental Improvements Like I mentioned earlier, I didn't wake up one day and realize if I actually read the recipe, prepped ahead of time, and researched how to do certain kitchen techniques (again, ahead of time), I could maximize my time in the kitchen and feel less overwhelmed. In fact, I'm probably 50:50 in my ability to prep and run in parallel or haphazardly skim in series today. But snaps for me because this week I measured everything out before I started cooking! I'm sure you could make an argument that my dad is a 'senior' in the kitchen and I'm not (but I'm also not junior either), but he'd prefer you only use 'senior' when used in conjunction with "senior discount" at this point in his life. Let's say 'seasoned'. Whether you are a junior or senior dev, you still need the content you are consuming to prepare you for success. But with more and more folks using services like Blue Apron, Hello Fresh, Home Chef, arguably boxed Bootcamp experiences for the kitchen, we have a new generation of folks training themselves how to follow recipes and we can translate that experience into the tech world, allowing for more confident, empowered folks in the kitchen and at the keyboard. So instead of shouting "read the docs" or "follow the tutorial" make sure your content is as consumable and delicious as a home cooked meal.

The principal built-in types are numerics, sequences, mappings, classes, instances and exceptions. Some collection classes are mutable. The methods that add, subtract, or rearrange their members in place, and don’t return a specific item, never return the collection instance itself but None . Some operations are supported by several object types; in particular, practically all objects can be compared for equality, tested for truth value, and converted to a string (with the repr() function or the slightly different str() function). The latter function is implicitly used when an object is written by the print() function. Truth Value Testing ¶ Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object. [ 1 ] If one of the methods raises an exception when called, the exception is propagated and the object does not have a truth value (for example, NotImplemented ). Here are most of the built-in objects considered false: constants defined to be false: None and False zero of any numeric type: 0 , 0.0 , 0j , Decimal(0) , Fraction(0, 1) empty sequences and collections: '' , () , [] , {} , set() , range(0) Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.) Boolean Operations — and , or , not ¶ These are the Boolean operations, ordered by ascending priority: Operation Result Notes x or y if x is true, then x , else y (1) x and y if x is false, then x , else y (2) not x if x is false, then True , else False (3) Notes: This is a short-circuit operator, so it only evaluates the second argument if the first one is false. This is a short-circuit operator, so it only evaluates the second argument if the first one is true. not has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b) , and a == not b is a syntax error. Comparisons ¶ There are eight comparison operations in Python. They all have the same priority (which is higher than that of the Boolean operations). Comparisons can be chained arbitrarily; for example, x < y <= z is equivalent to x < y and y <= z , except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false). This table summarizes the comparison operations: Operation Meaning < strictly less than <= less than or equal > strictly greater than >= greater than or equal == equal != not equal is object identity is not negated object identity Unless stated otherwise, objects of different types never compare equal. The == operator is always defined but for some object types (for example, class objects) is equivalent to is . The < , <= , > and >= operators are only defined where they make sense; for example, they raise a TypeError exception when one of the arguments is a complex number. Non-identical instances of a class normally compare as non-equal unless the class defines the __eq__() method. Instances of a class cannot be ordered with respect to other instances of the same class, or other types of object, unless the class defines enough of the methods __lt__() , __le__() , __gt__() , and __ge__() (in general, __lt__() and __eq__() are sufficient, if you want the conventional meanings of the comparison operators). The behavior of the is and is not operators cannot be customized; also they can be applied to any two objects and never raise an exception. Two more operations with the same syntactic priority, in and not in , are supported by types that are iterable or implement the __contains__() method. Numeric Types — int , float , complex ¶ There are three distinct numeric types: integers , floating-point numbers , and complex numbers . In addition, Booleans are a subtype of integers. Integers have unlimited precision. Floating-point numbers are usually implemented using double in C; information about the precision and internal representation of floating-point numbers for the machine on which your program is running is available in sys.float_info . Complex numbers have a real and imaginary part, which are each a floating-point number. To extract these parts from a complex number z , use z.real and z.imag . (The standard library includes the additional numeric types fractions.Fraction , for rationals, and decimal.Decimal , for floating-point numbers with user-definable precision.) Numbers are created by numeric literals or as the result of built-in functions and operators. Unadorned integer literals (including hex, octal and binary numbers) yield integers. Numeric literals containing a decimal point or an exponent sign yield floating-point numbers. Appending 'j' or 'J' to a numeric literal yields an imaginary number (a complex number with a zero real part) which you can add to an integer or float to get a complex number with real and imaginary parts. The constructors int() , float() , and complex() can be used to produce numbers of a specific type. Python fully supports mixed arithmetic: when a binary arithmetic operator has operands of different numeric types, the operand with the “narrower” type is widened to that of the other, where integer is narrower than floating point. Arithmetic with complex and real operands is defined by the usual mathematical formula, for example: x + complex ( u , v ) = complex ( x + u , v ) x * complex ( u , v ) = complex ( x * u , x * v ) A comparison between numbers of different types behaves as though the exact values of those numbers were being compared. [ 2 ] All numeric types (except complex) support the following operations (for priorities of the operations, see Operator precedence ): Operation Result Notes Full documentation x + y sum of x and y x - y difference of x and y x * y product of x and y x / y quotient of x and y x // y floored quotient of x and y (1)(2) x % y remainder of x / y (2) -x x negated +x x unchanged abs(x) absolute value or magnitude of x abs() int(x) x converted to integer (3)(6) int() float(x) x converted to floating point (4)(6) float() complex(re, im) a complex number with real part re , imaginary part im . im defaults to zero. (6) complex() c.conjugate() conjugate of the complex number c divmod(x, y) the pair (x // y, x % y) (2) divmod() pow(x, y) x to the power y (5) pow() x ** y x to the power y (5) Notes: Also referred to as integer division. For operands of type int , the result has type int . For operands of type float , the result has type float . In general, the result is a whole integer, though the result’s type is not necessarily int . The result is always rounded towards minus infinity: 1//2 is 0 , (-1)//2 is -1 , 1//(-2) is -1 , and (-1)//(-2) is 0 . Not for complex numbers. Instead convert to floats using abs() if appropriate. Conversion from float to int truncates, discarding the fractional part. See functions math.floor() and math.ceil() for alternative conversions. float also accepts the strings “nan” and “inf” with an optional prefix “+” or “-” for Not a Number (NaN) and positive or negative infinity. Python defines pow(0, 0) and 0 ** 0 to be 1 , as is common for programming languages. The numeric literals accepted include the digits 0 to 9 or any Unicode equivalent (code points with the Nd property). See the Unicode Standard for a complete list of code points with the Nd property. All numbers.Real types ( int and float ) also include the following operations: Operation Result math.trunc(x) x truncated to Integral round(x[, n]) x rounded to n digits, rounding half to even. If n is omitted, it defaults to 0. math.floor(x) the greatest Integral <= x math.ceil(x) the least Integral >= x For additional numeric operations see the math and cmath modules. Bitwise Operations on Integer Types ¶ Bitwise operations only make sense for integers. The result of bitwise operations is calculated as though carried out in two’s complement with an infinite number of sign bits. The priorities of the binary bitwise operations are all lower than the numeric operations and higher than the comparisons; the unary operation ~ has the same priority as the other unary numeric operations ( + and - ). This table lists the bitwise operations sorted in ascending priority: Operation Result Notes x | y bitwise or of x and y (4) x ^ y bitwise exclusive or of x and y (4) x & y bitwise and of x and y (4) x << n x shifted left by n bits (1)(2) x >> n x shifted right by n bits (1)(3) ~x the bits of x inverted Notes: Negative shift counts are illegal and cause a ValueError to be raised. A left shift by n bits is equivalent to multiplication by pow(2, n) . A right shift by n bits is equivalent to floor division by pow(2, n) . Performing these calculations with at least one extra sign extension bit in a finite two’s complement representation (a working bit-width of 1 + max(x.bit_length(), y.bit_length()) or more) is sufficient to get the same result as if there were an infinite number of sign bits. Additional Methods on Integer Types ¶ The int type implements the numbers.Integral abstract base class . In addition, it provides a few more methods: int. bit_length ( ) ¶ Return the number of bits necessary to represent an integer in binary, excluding the sign and leading zeros: >>> n = - 37 >>> bin ( n ) '-0b100101' >>> n . bit_length () 6 More precisely, if x is nonzero, then x.bit_length() is the unique positive integer k such that 2**(k-1) <= abs(x) < 2**k . Equivalently, when abs(x) is small enough to have a correctly rounded logarithm, then k = 1 + int(log(abs(x), 2)) . If x is zero, then x.bit_length() returns 0 . Equivalent to: def bit_length ( self ): s = bin ( self ) # binary representation: bin(-37) --> '-0b100101' s = s . lstrip ( '-0b' ) # remove leading zeros and minus sign return len ( s ) # len('100101') --> 6 Added in version 3.1. int. bit_count ( ) ¶ Return the number of ones in the binary representation of the absolute value of the integer. This is also known as the population count. Example: >>> n = 19 >>> bin ( n ) '0b10011' >>> n . bit_count () 3 >>> ( - n ) . bit_count () 3 Equivalent to: def bit_count ( self ): return bin ( self ) . count ( "1" ) Added in version 3.10. int. to_bytes ( length = 1 , byteorder = 'big' , * , signed = False ) ¶ Return an array of bytes representing an integer. >>> ( 1024 ) . to_bytes ( 2 , byteorder = 'big' ) b'\x04\x00' >>> ( 1024 ) . to_bytes ( 10 , byteorder = 'big' ) b'\x00\x00\x00\x00\x00\x00\x00\x00\x04\x00' >>> ( - 1024 ) . to_bytes ( 10 , byteorder = 'big' , signed = True ) b'\xff\xff\xff\xff\xff\xff\xff\xff\xfc\x00' >>> x = 1000 >>> x . to_bytes (( x . bit_length () + 7 ) // 8 , byteorder = 'little' ) b'\xe8\x03' The integer is represented using length bytes, and defaults to 1. An OverflowError is raised if the integer is not representable with the given number of bytes. The byteorder argument determines the byte order used to represent the integer, and defaults to "big" . If byteorder is "big" , the most significant byte is at the beginning of the byte array. If byteorder is "little" , the most significant byte is at the end of the byte array. The signed argument determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised. The default value for signed is False . The default values can be used to conveniently turn an integer into a single byte object: >>> ( 65 ) . to_bytes () b'A' However, when using the default arguments, don’t try to convert a value greater than 255 or you’ll get an OverflowError . Equivalent to: def to_bytes ( n , length = 1 , byteorder = 'big' , signed = False ): if byteorder == 'little' : order = range ( length ) elif byteorder == 'big' : order = reversed ( range ( length )) else : raise ValueError ( "byteorder must be either 'little' or 'big'" ) return bytes (( n >> i * 8 ) & 0xff for i in order ) Added in version 3.2. Changed in version 3.11: Added default argument values for length and byteorder . classmethod int. from_bytes ( bytes , byteorder = 'big' , * , signed = False ) ¶ Return the integer represented by the given array of bytes. >>> int . from_bytes ( b ' \x00\x10 ' , byteorder = 'big' ) 16 >>> int . from_bytes ( b ' \x00\x10 ' , byteorder = 'little' ) 4096 >>> int . from_bytes ( b ' \xfc\x00 ' , byteorder = 'big' , signed = True ) -1024 >>> int . from_bytes ( b ' \xfc\x00 ' , byteorder = 'big' , signed = False ) 64512 >>> int . from_bytes ([ 255 , 0 , 0 ], byteorder = 'big' ) 16711680 The argument bytes must either be a bytes-like object or an iterable producing bytes. The byteorder argument determines the byte order used to represent the integer, and defaults to "big" . If byteorder is "big" , the most significant byte is at the beginning of the byte array. If byteorder is "little" , the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. The signed argument indicates whether two’s complement is used to represent the integer. Equivalent to: def from_bytes ( bytes , byteorder = 'big' , signed = False ): if byteorder == 'little' : little_ordered = list ( bytes ) elif byteorder == 'big' : little_ordered = list ( reversed ( bytes )) else : raise ValueError ( "byteorder must be either 'little' or 'big'" ) n = sum ( b << i * 8 for i , b in enumerate ( little_ordered )) if signed and little_ordered and ( little_ordered [ - 1 ] & 0x80 ): n -= 1 << 8 * len ( little_ordered ) return n Added in version 3.2. Changed in version 3.11: Added default argument value for byteorder . int. as_integer_ratio ( ) ¶ Return a pair of integers whose ratio is equal to the original integer and has a positive denominator. The integer ratio of integers (whole numbers) is always the integer as the numerator and 1 as the denominator. Added in version 3.8. int. is_integer ( ) ¶ Returns True . Exists for duck type compatibility with float.is_integer() . Added in version 3.12. Additional Methods on Float ¶ The float type implements the numbers.Real abstract base class . float also has the following additional methods. classmethod float. from_number ( x ) ¶ Class method to return a floating-point number constructed from a number x . If the argument is an integer or a floating-point number, a floating-point number with the same value (within Python’s floating-point precision) is returned. If the argument is outside the range of a Python float, an OverflowError will be raised. For a general Python object x , float.from_number(x) delegates to x.__float__() . If __float__() is not defined then it falls back to __index__() . Added in version 3.14. float. as_integer_ratio ( ) ¶ Return a pair of integers whose ratio is exactly equal to the original float. The ratio is in lowest terms and has a positive denominator. Raises OverflowError on infinities and a ValueError on NaNs. float. is_integer ( ) ¶ Return True if the float instance is finite with integral value, and False otherwise: >>> ( - 2.0 ) . is_integer () True >>> ( 3.2 ) . is_integer () False Two methods support conversion to and from hexadecimal strings. Since Python’s floats are stored internally as binary numbers, converting a float to or from a decimal string usually involves a small rounding error. In contrast, hexadecimal strings allow exact representation and specification of floating-point numbers. This can be useful when debugging, and in numerical work. float. hex ( ) ¶ Return a representation of a floating-point number as a hexadecimal string. For finite floating-point numbers, this representation will always include a leading 0x and a trailing p and exponent. classmethod float. fromhex ( s ) ¶ Class method to return the float represented by a hexadecimal string s . The string s may have leading and trailing whitespace. Note that float.hex() is an instance method, while float.fromhex() is a class method. A hexadecimal string takes the form: [ sign ] [ '0x' ] integer [ '.' fraction ] [ 'p' exponent ] where the optional sign may by either + or - , integer and fraction are strings of hexadecimal digits, and exponent is a decimal integer with an optional leading sign. Case is not significant, and there must be at least one hexadecimal digit in either the integer or the fraction. This syntax is similar to the syntax specified in section 6.4.4.2 of the C99 standard, and also to the syntax used in Java 1.5 onwards. In particular, the output of float.hex() is usable as a hexadecimal floating-point literal in C or Java code, and hexadecimal strings produced by C’s %a format character or Java’s Double.toHexString are accepted by float.fromhex() . Note that the exponent is written in decimal rather than hexadecimal, and that it gives the power of 2 by which to multiply the coefficient. For example, the hexadecimal string 0x3.a7p10 represents the floating-point number (3 + 10./16 + 7./16**2) * 2.0**10 , or 3740.0 : >>> float . fromhex ( '0x3.a7p10' ) 3740.0 Applying the reverse conversion to 3740.0 gives a different hexadecimal string representing the same number: >>> float . hex ( 3740.0 ) '0x1.d380000000000p+11' Additional Methods on Complex ¶ The complex type implements the numbers.Complex abstract base class . complex also has the following additional methods. classmethod complex. from_number ( x ) ¶ Class method to convert a number to a complex number. For a general Python object x , complex.from_number(x) delegates to x.__complex__() . If __complex__() is not defined then it falls back to __float__() . If __float__() is not defined then it falls back to __index__() . Added in version 3.14. Hashing of numeric types ¶ For numbers x and y , possibly of different types, it’s a requirement that hash(x) == hash(y) whenever x == y (see the __hash__() method documentation for more details). For ease of implementation and efficiency across a variety of numeric types (including int , float , decimal.Decimal and fractions.Fraction ) Python’s hash for numeric types is based on a single mathematical function that’s defined for any rational number, and hence applies to all instances of int and fractions.Fraction , and all finite instances of float and decimal.Decimal . Essentially, this function is given by reduction modulo P for a fixed prime P . The value of P is made available to Python as the modulus attribute of sys.hash_info . CPython implementation detail: Currently, the prime used is P = 2**31 - 1 on machines with 32-bit C longs and P = 2**61 - 1 on machines with 64-bit C longs. Here are the rules in detail: If x = m / n is a nonnegative rational number and n is not divisible by P , define hash(x) as m * invmod(n, P) % P , where invmod(n, P) gives the inverse of n modulo P . If x = m / n is a nonnegative rational number and n is divisible by P (but m is not) then n has no inverse modulo P and the rule above doesn’t apply; in this case define hash(x) to be the constant value sys.hash_info.inf . If x = m / n is a negative rational number define hash(x) as -hash(-x) . If the resulting hash is -1 , replace it with -2 . The particular values sys.hash_info.inf and -sys.hash_info.inf are used as hash values for positive infinity or negative infinity (respectively). For a complex number z , the hash values of the real and imaginary parts are combined by computing hash(z.real) + sys.hash_info.imag * hash(z.imag) , reduced modulo 2**sys.hash_info.width so that it lies in range(-2**(sys.hash_info.width - 1), 2**(sys.hash_info.width - 1)) . Again, if the result is -1 , it’s replaced with -2 . To clarify the above rules, here’s some example Python code, equivalent to the built-in hash, for computing the hash of a rational number, float , or complex : import sys , math def hash_fraction ( m , n ): """Compute the hash of a rational number m / n. Assumes m and n are integers, with n positive. Equivalent to hash(fractions.Fraction(m, n)). """ P = sys . hash_info . modulus # Remove common factors of P. (Unnecessary if m and n already coprime.) while m % P == n % P == 0 : m , n = m // P , n // P if n % P == 0 : hash_value = sys . hash_info . inf else : # Fermat's Little Theorem: pow(n, P-1, P) is 1, so # pow(n, P-2, P) gives the inverse of n modulo P. hash_value = ( abs ( m ) % P ) * pow ( n , P - 2 , P ) % P if m < 0 : hash_value = - hash_value if hash_value == - 1 : hash_value = - 2 return hash_value def hash_float ( x ): """Compute the hash of a float x.""" if math . isnan ( x ): return object . __hash__ ( x ) elif math . isinf ( x ): return sys . hash_info . inf if x > 0 else - sys . hash_info . inf else : return hash_fraction ( * x . as_integer_ratio ()) def hash_complex ( z ): """Compute the hash of a complex number z.""" hash_value = hash_float ( z . real ) + sys . hash_info . imag * hash_float ( z . imag ) # do a signed reduction modulo 2**sys.hash_info.width M = 2 ** ( sys . hash_info . width - 1 ) hash_value = ( hash_value & ( M - 1 )) - ( hash_value & M ) if hash_value == - 1 : hash_value = - 2 return hash_value Boolean Type - bool ¶ Booleans represent truth values. The bool type has exactly two constant instances: True and False . The built-in function bool() converts any value to a boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above). For logical operations, use the boolean operators and , or and not . When applying the bitwise operators & , | , ^ to two booleans, they return a bool equivalent to the logical operations “and”, “or”, “xor”. However, the logical operators and , or and != should be preferred over & , | and ^ . Deprecated since version 3.12: The use of the bitwise inversion operator ~ is deprecated and will raise an error in Python 3.16. bool is a subclass of int (see Numeric Types — int, float, complex ). In many numeric contexts, False and True behave like the integers 0 and 1, respectively. However, relying on this is discouraged; explicitly convert using int() instead. Iterator Types ¶ Python supports a concept of iteration over containers. This is implemented using two distinct methods; these are used to allow user-defined classes to support iteration. Sequences, described below in more detail, always support the iteration methods. One method needs to be defined for container objects to provide iterable support: container. __iter__ ( ) ¶ Return an iterator object. The object is required to support the iterator protocol described below. If a container supports different types of iteration, additional methods can be provided to specifically request iterators for those iteration types. (An example of an object supporting multiple forms of iteration would be a tree structure which supports both breadth-first and depth-first traversal.) This method corresponds to the tp_iter slot of the type structure for Python objects in the Python/C API. The iterator objects themselves are required to support the following two methods, which together form the iterator protocol : iterator. __iter__ ( ) ¶ Return the iterator object itself. This is required to allow both containers and iterators to be used with the for and in statements. This method corresponds to the tp_iter slot of the type structure for Python objects in the Python/C API. iterator. __next__ ( ) ¶ Return the next item from the iterator . If there are no further items, raise the StopIteration exception. This method corresponds to the tp_iternext slot of the type structure for Python objects in the Python/C API. Python defines several iterator objects to support iteration over general and specific sequence types, dictionaries, and other more specialized forms. The specific types are not important beyond their implementation of the iterator protocol. Once an iterator’s __next__() method raises StopIteration , it must continue to do so on subsequent calls. Implementations that do not obey this property are deemed broken. Generator Types ¶ Python’s generator s provide a convenient way to implement the iterator protocol. If a container object’s __iter__() method is implemented as a generator, it will automatically return an iterator object (technically, a generator object) supplying the __iter__() and __next__() methods. More information about generators can be found in the documentation for the yield expression . Sequence Types — list , tuple , range ¶ There are three basic sequence types: lists, tuples, and range objects. Additional sequence types tailored for processing of binary data and text strings are described in dedicated sections. Common Sequence Operations ¶ The operations in the following table are supported by most sequence types, both mutable and immutable. The collections.abc.Sequence ABC is provided to make it easier to correctly implement these operations on custom sequence types. This table lists the sequence operations sorted in ascending priority. In the table, s and t are sequences of the same type, n , i , j and k are integers and x is an arbitrary object that meets any type and value restrictions imposed by s . The in and not in operations have the same priorities as the comparison operations. The + (concatenation) and * (repetition) operations have the same priority as the corresponding numeric operations. [ 3 ] Operation Result Notes x in s True if an item of s is equal to x , else False (1) x not in s False if an item of s is equal to x , else True (1) s + t the concatenation of s and t (6)(7) s * n or n * s equivalent to adding s to itself n times (2)(7) s[i] i th item of s , origin 0 (3)(8) s[i:j] slice of s from i to j (3)(4) s[i:j:k] slice of s from i to j with step k (3)(5) len(s) length of s min(s) smallest item of s max(s) largest item of s Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length. (For full details see Comparisons in the language reference.) Forward and reversed iterators over mutable sequences access values using an index. That index will continue to march forward (or backward) even if the underlying sequence is mutated. The iterator terminates only when an IndexError or a StopIteration is encountered (or when the index drops below zero). Notes: While the in and not in operations are used only for simple containment testing in the general case, some specialised sequences (such as str , bytes and bytearray ) also use them for subsequence testing: >>> "gg" in "eggs" True Values of n less than 0 are treated as 0 (which yields an empty sequence of the same type as s ). Note that items in the sequence s are not copied; they are referenced multiple times. This often haunts new Python programmers; consider: >>> lists = [[]] * 3 >>> lists [[], [], []] >>> lists [ 0 ] . append ( 3 ) >>> lists [[3], [3], [3]] What has happened is that [[]] is a one-element list containing an empty list, so all three elements of [[]] * 3 are references to this single empty list. Modifying any of the elements of lists modifies this single list. You can create a list of different lists this way: >>> lists = [[] for i in range ( 3 )] >>> lists [ 0 ] . append ( 3 ) >>> lists [ 1 ] . append ( 5 ) >>> lists [ 2 ] . append ( 7 ) >>> lists [[3], [5], [7]] Further explanation is available in the FAQ entry How do I create a multidimensional list? . If i or j is negative, the index is relative to the end of sequence s : len(s) + i or len(s) + j is substituted. But note that -0 is still 0 . The slice of s from i to j is defined as the sequence of items with index k such that i <= k < j . If i is omitted or None , use 0 . If j is omitted or None , use len(s) . If i or j is less than -len(s) , use 0 . If i or j is greater than len(s) , use len(s) . If i is greater than or equal to j , the slice is empty. The slice of s from i to j with step k is defined as the sequence of items with index x = i + n*k such that 0 <= n < (j-i)/k . In other words, the indices are i , i+k , i+2*k , i+3*k and so on, stopping when j is reached (but never including j ). When k is positive, i and j are reduced to len(s) if they are greater. When k is negative, i and j are reduced to len(s) - 1 if they are greater. If i or j are omitted or None , they become “end” values (which end depends on the sign of k ). Note, k cannot be zero. If k is None , it is treated like 1 . Concatenating immutable sequences always results in a new object. This means that building up a sequence by repeated concatenation will have a quadratic runtime cost in the total sequence length. To get a linear runtime cost, you must switch to one of the alternatives below: if concatenating str objects, you can build a list and use str.join() at the end or else write to an io.StringIO instance and retrieve its value when complete if concatenating bytes objects, you can similarly use bytes.join() or io.BytesIO , or you can do in-place concatenation with a bytearray object. bytearray objects are mutable and have an efficient overallocation mechanism if concatenating tuple objects, extend a list instead for other types, investigate the relevant class documentation Some sequence types (such as range ) only support item sequences that follow specific patterns, and hence don’t support sequence concatenation or repetition. An IndexError is raised if i is outside the sequence range. Sequence Methods Sequence types also support the following methods: sequence. count ( value , / ) ¶ Return the total number of occurrences of value in sequence . sequence. index ( value[, start[, stop] ) ¶ Return the index of the first occurrence of value in sequence . Raises ValueError if value is not found in sequence . The start or stop arguments allow for efficient searching of subsections of the sequence, beginning at start and ending at stop . This is roughly equivalent to start + sequence[start:stop].index(value) , only without copying any data. Caution Not all sequence types support passing the start and stop arguments. Immutable Sequence Types ¶ The only operation that immutable sequence types generally implement that is not also implemented by mutable sequence types is support for the hash() built-in. This support allows immutable sequences, such as tuple instances, to be used as dict keys and stored in set and frozenset instances. Attempting to hash an immutable sequence that contains unhashable values will result in TypeError . Mutable Sequence Types ¶ The operations in the following table are defined on mutable sequence types. The collections.abc.MutableSequence ABC is provided to make it easier to correctly implement these operations on custom sequence types. In the table s is an instance of a mutable sequence type, t is any iterable object and x is an arbitrary object that meets any type and value restrictions imposed by s (for example, bytearray only accepts integers that meet the value restriction 0 <= x <= 255 ). Operation Result Notes s[i] = x item i of s is replaced by x del s[i] removes item i of s s[i:j] = t slice of s from i to j is replaced by the contents of the iterable t del s[i:j] removes the elements of s[i:j] from the list (same as s[i:j] = [] ) s[i:j:k] = t the elements of s[i:j:k] are replaced by those of t (1) del s[i:j:k] removes the elements of s[i:j:k] from the list s += t extends s with the contents of t (for the most part the same as s[len(s):len(s)] = t ) s *= n updates s with its contents repeated n times (2) Notes: If k is not equal to 1 , t must have the same length as the slice it is replacing. The value n is an integer, or an object implementing __index__() . Zero and negative values of n clear the sequence. Items in the sequence are not copied; they are referenced multiple times, as explained for s * n under Common Sequence Operations . Mutable Sequence Methods Mutable sequence types also support the following methods: sequence. append ( value , / ) ¶ Append value to the end of the sequence This is equivalent to writing seq[len(seq):len(seq)] = [value] . sequence. clear ( ) ¶ Added in version 3.3. Remove all items from sequence . This is equivalent to writing del sequence[:] . sequence. copy ( ) ¶ Added in version 3.3. Create a shallow copy of sequence . This is equivalent to writing sequence[:] . Hint The copy() method is not part of the MutableSequence ABC , but most concrete mutable sequence types provide it. sequence. extend ( iterable , / ) ¶ Extend sequence with the contents of iterable . For the most part, this is the same as writing seq[len(seq):len(seq)] = iterable . sequence. insert ( index , value , / ) ¶ Insert value into sequence at the given index . This is equivalent to writing sequence[index:index] = [value] . sequence. pop ( index = -1 , / ) ¶ Retrieve the item at index and also removes it from sequence . By default, the last item in sequence is removed and returned. sequence. remove ( value , / ) ¶ Remove the first item from sequence where sequence[i] == value . Raises ValueError if value is not found in sequence . sequence. reverse ( ) ¶ Reverse the items of sequence in place. This method maintains economy of space when reversing a large sequence. To remind users that it operates by side-effect, it returns None . Lists ¶ Lists are mutable sequences, typically used to store collections of homogeneous items (where the precise degree of similarity will vary by application). class list ( iterable = () , / ) ¶ Lists may be constructed in several ways: Using a pair of square brackets to denote the empty list: [] Using square brackets, separating items with commas: [a] , [a, b, c] Using a list comprehension: [x for x in iterable] Using the type constructor: list() or list(iterable) The constructor builds a list whose items are the same and in the same order as iterable ’s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If iterable is already a list, a copy is made and returned, similar to iterable[:] . For example, list('abc') returns ['a', 'b', 'c'] and list( (1, 2, 3) ) returns [1, 2, 3] . If no argument is given, the constructor creates a new empty list, [] . Many other operations also produce lists, including the sorted() built-in. Lists implement all of the common and mutable sequence operations. Lists also provide the following additional method: sort ( * , key = None , reverse = False ) ¶ This method sorts the list in place, using only < comparisons between items. Exceptions are not suppressed - if any comparison operations fail, the entire sort operation will fail (and the list will likely be left in a partially modified state). sort() accepts two arguments that can only be passed by keyword ( keyword-only arguments ): key specifies a function of one argument that is used to extract a comparison key from each list element (for example, key=str.lower ). The key corresponding to each item in the list is calculated once and then used for the entire sorting process. The default value of None means that list items are sorted directly without calculating a separate key value. The functools.cmp_to_key() utility is available to convert a 2.x style cmp function to a key function. reverse is a boolean value. If set to True , then the list elements are sorted as if each comparison were reversed. This method modifies the sequence in place for economy of space when sorting a large sequence. To remind users that it operates by side effect, it does not return the sorted sequence (use sorted() to explicitly request a new sorted list instance). The sort() method is guaranteed to be stable. A sort is stable if it guarantees not to change the relative order of elements that compare equal — this is helpful for sorting in multiple passes (for example, sort by department, then by salary grade). For sorting examples and a brief sorting tutorial, see Sorting Techniques . CPython implementation detail: While a list is being sorted, the effect of attempting to mutate, or even inspect, the list is undefined. The C implementation of Python makes the list appear empty for the duration, and raises ValueError if it can detect that the list has been mutated during a sort. Thread safety Reading a single element from a list is atomic : lst [ i ] # list.__getitem__ The following methods traverse the list and use atomic reads of each item to perform their function. That means that they may return results affected by concurrent modifications: item in lst lst . index ( item ) lst . count ( item ) All of the above methods/operations are also lock-free. They do not block concurrent modifications. Other operations that hold a lock will not block these from observing intermediate states. All other operations from here on block using the per-object lock. Writing a single item via lst[i] = x is safe to call from multiple threads and will not corrupt the list. The following operations return new objects and appear atomic to other threads: lst1 + lst2 # concatenates two lists into a new list x * lst # repeats lst x times into a new list lst . copy () # returns a shallow copy of the list Methods that only operate on a single elements with no shifting required are atomic : lst . append ( x ) # append to the end of the list, no shifting required lst . pop () # pop element from the end of the list, no shifting required The clear() method is also atomic . Other threads cannot observe elements being removed. The sort() method is not atomic . Other threads cannot observe intermediate states during sorting, but the list appears empty for the duration of the sort. The following operations may allow lock-free operations to observe intermediate states since they modify multiple elements in place: lst . insert ( idx , item ) # shifts elements lst . pop ( idx ) # idx not at the end of the list, shifts elements lst *= x # copies elements in place The remove() method may allow concurrent modifications since element comparison may execute arbitrary Python code (via __eq__() ). extend() is safe to call from multiple threads. However, its guarantees depend on the iterable passed to it. If it is a list , a tuple , a set , a frozenset , a dict or a dictionary view object (but not their subclasses), the extend operation is safe from concurrent modifications to the iterable. Otherwise, an iterator is created which can be concurrently modified by another thread. The same applies to inplace concatenation of a list with other iterables when using lst += iterable . Similarly, assigning to a list slice with lst[i:j] = iterable is safe to call from multiple threads, but iterable is only locked when it is also a list (but not its subclasses). Operations that involve multiple accesses, as well as iteration, are never atomic. For example: # NOT atomic: read-modify-write lst [ i ] = lst [ i ] + 1 # NOT atomic: check-then-act if lst : item = lst . pop () # NOT thread-safe: iteration while modifying for item in lst : process ( item ) # another thread may modify lst Consider external synchronization when sharing list instances across threads. See Python support for free threading for more information. Tuples ¶ Tuples are immutable sequences, typically used to store collections of heterogeneous data (such as the 2-tuples produced by the enumerate() built-in). Tuples are also used for cases where an immutable sequence of homogeneous data is needed (such as allowing storage in a set or dict instance). class tuple ( iterable = () , / ) ¶ Tuples may be constructed in a number of ways: Using a pair of parentheses to denote the empty tuple: () Using a trailing comma for a singleton tuple: a, or (a,) Separating items with commas: a, b, c or (a, b, c) Using the tuple() built-in: tuple() or tuple(iterable) The constructor builds a tuple whose items are the same and in the same order as iterable ’s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If iterable is already a tuple, it is returned unchanged. For example, tuple('abc') returns ('a', 'b', 'c') and tuple( [1, 2, 3] ) returns (1, 2, 3) . If no argument is given, the constructor creates a new empty tuple, () . Note that it is actually the comma which makes a tuple, not the parentheses. The parentheses are optional, except in the empty tuple case, or when they are needed to avoid syntactic ambiguity. For example, f(a, b, c) is a function call with three arguments, while f((a, b, c)) is a function call with a 3-tuple as the sole argument. Tuples implement all of the common sequence operations. For heterogeneous collections of data where access by name is clearer than access by index, collections.namedtuple() may be a more appropriate choice than a simple tuple object. Ranges ¶ The range type represents an immutable sequence of numbers and is commonly used for looping a specific number of times in for loops. class range ( stop , / ) ¶ class range ( start , stop , step = 1 , / ) The arguments to the range constructor must be integers (either built-in int or any object that implements the __index__() special method). If the step argument is omitted, it defaults to 1 . If the start argument is omitted, it defaults to 0 . If step is zero, ValueError is raised. For a positive step , the contents of a range r are determined by the formula r[i] = start + step*i where i >= 0 and r[i] < stop . For a negative step , the contents of the range are still determined by the formula r[i] = start + step*i , but the constraints are i >= 0 and r[i] > stop . A range object will be empty if r[0] does not meet the value constraint. Ranges do support negative indices, but these are interpreted as indexing from the end of the sequence determined by the positive indices. Ranges containing absolute values larger than sys.maxsize are permitted but some features (such as len() ) may raise OverflowError . Range examples: >>> list ( range ( 10 )) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> list ( range ( 1 , 11 )) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> list ( range ( 0 , 30 , 5 )) [0, 5, 10, 15, 20, 25] >>> list ( range ( 0 , 10 , 3 )) [0, 3, 6, 9] >>> list ( range ( 0 , - 10 , - 1 )) [0, -1, -2, -3, -4, -5, -6, -7, -8, -9] >>> list ( range ( 0 )) [] >>> list ( range ( 1 , 0 )) [] Ranges implement all of the common sequence operations except concatenation and repetition (due to the fact that range objects can only represent sequences that follow a strict pattern and repetition and concatenation will usually violate that pattern). start ¶ The value of the start parameter (or 0 if the parameter was not supplied) stop ¶ The value of the stop parameter step ¶ The value of the step parameter (or 1 if the parameter was not supplied) The advantage of the range type over a regular list or tuple is that a range object will always take the same (small) amount of memory, no matter the size of the range it represents (as it only stores the start , stop and step values, calculating individual items and subranges as needed). Range objects implement the collections.abc.Sequence ABC, and provide features such as containment tests, element index lookup, slicing and support for negative indices (see Sequence Types — list, tuple, range ): >>> r = range ( 0 , 20 , 2 ) >>> r range(0, 20, 2) >>> 11 in r False >>> 10 in r True >>> r . index ( 10 ) 5 >>> r [ 5 ] 10 >>> r [: 5 ] range(0, 10, 2) >>> r [ - 1 ] 18 Testing range objects for equality with == and != compares them as sequences. That is, two range objects are considered equal if they represent the same sequence of values. (Note that two range objects that compare equal might have different start , stop and step attributes, for example range(0) == range(2, 1, 3) or range(0, 3, 2) == range(0, 4, 2) .) Changed in version 3.2: Implement the Sequence ABC. Support slicing and negative indices. Test int objects for membership in constant time instead of iterating through all items. Changed in version 3.3: Define ‘==’ and ‘!=’ to compare range objects based on the sequence of values they define (instead of comparing based on object identity). Added the start , stop and step attributes. See also The linspace recipe shows how to implement a lazy version of range suitable for floating-point applications. Text and Binary Sequence Type Methods Summary ¶ The following table summarizes the text and binary sequence types methods by category.

Strings are immutable sequences of Unicode code points. String literals are written in a variety of ways: Single quotes: 'allows embedded "double" quotes' Double quotes: "allows embedded 'single' quotes" Triple quoted: '''Three single quotes''' , """Three double quotes""" Triple quoted strings may span multiple lines - all associated whitespace will be included in the string literal. String literals that are part of a single expression and have only whitespace between them will be implicitly converted to a single string literal. That is, ("spam " "eggs") == "spam eggs" . See String and Bytes literals for more about the various forms of string literal

OpenAI Open in ChatGPT ​ How Suprsend identifies a user SuprSend identifies users with immutable distinct_id . It’s best to map the same identifier in your DB with distinct_id in SuprSend. Do not use identifiers that can be changed like email or phone number. You can view synced users by searching distinct_id on Users page . ​ Identify user and Set Push token 1 Create/Identify a new user You can identify a user using the suprsend.identify() method. iospsuh token is automatically set in user’s profile when this method is called. Call this method as soon as you know the identity of user, that is after login authentication. If you don’t call this method, user will be identified using distinct_id (uuid) that SDK generates internally. We internally create an event called $user_login . You can see this event on SuprSend workflows event list and you can configure a workflow on it. javascript Copy Ask AI suprsend . identify ( distinct_id ); //Sample Values suprsend . identify ( "291eaa13-62f5-4d52-b2dd" ); Parameters Type Description distinct_id int, bigint, string, UUID mandatory Unique identifier for a user across devices or between multiple logins. 2 Call reset to clear user data on log out As soon as the user logs out, call suprsend.reset() method to clear data attributed to a user. This allows you to handle multiple user logins on a single device and keep their data isolated from each other. javascript Copy Ask AI suprsend . reset (); Don’t forget to call reset on user logout. If not called, users’ distinct_id will not reset and multiple tokens and channels will get added to the distinct_id who logged in first on the device. ​ Set communication channels Mobile Push tokens automatically gets updated in user profile on suprsend.identify() call. All you have to do is to integrate push notification service in your application to start sending mobile push notification. To set other communication channels, use below methods: Add User Channels Add user channels on signup, or whenever a user updates their communication channels in the application flow. Javascript Copy Ask AI suprsend . user . setEmail ( " [email protected] " ); // To add Email suprsend . user . setSms ( "+91XXXXXXXXXX" ); // To add SMS, mandatory to pass country code suprsend . user . setWhatsApp ( "+91XXXXXXXXXX" ); // To add Whatsapp, mandatory to pass country code Remove User Channels Copy Ask AI suprsend.user.unSetEmail(" [email protected] "); // To remove Email suprsend.user.unSetSms("+91XXXXXXXXXX"); // To remove SMS suprsend.user.unSetWhatsApp("+91XXXXXXXXXX"); // To remove Whatsapp ​ Set user properties ( currently not available in iOS SDK ) You can sync other user properties in SuprSend and use it to pass dynamic content in template or add in workflow conditions. Set Set is used to add property. Set is upsert function and will override existing values corresponding to a key. javascript Copy Ask AI // for single property suprsend . user . set ( key , value ); suprsend . user . set ( "name" , "john doe" ); // for multiple properties suprsend . user . set ( property_obj ); suprsend . user . set ({ "name" : "john doe" , "age" : "27" }); Key should not start with $ or ss_ , as we have reserved these symbols for our internal events and property names. Set Once Works just like user.set , except it will not overwrite existing property values. This is useful for properties like First login date javascript Copy Ask AI suprsend . user . setOnce ( key , value ); // for single property suprsend . user . setOnce ( properties ); // for multiple properties // Sample values for setting once a single property: suprsend . user . setOnce ( "first_login" , "2021-11-02" ); // Sample values for setting once multiple properties: suprsend . user . setOnce ({ "first_login" : "2021-11-02" , "DOB" : "1991-10-02" }); Unset This will remove a property key javascript Copy Ask AI suprsend . user . unSet ( key ); // for single property suprsend . user . unSet ( property_list ); // for multiple properties // Sample values for unsetting a single property: suprsend . user . unSet ( "wishlist" ); // Sample values for unsetting multiple properties: suprsend . user . unSet ([ "wishlist" , "cart" ]); Append This method will append a value to an array javascript Copy Ask AI suprsend . user . append ( key , value ); suprsend . user . append ( property_obj ); // for multiple properties // Sample values for appending a single property: suprsend . user . append ( "wishlist" , "iphone12" ); // Sample values for appending multiple properties: suprsend . user . append ({ "wishlist" : "iphone12" , "wishlist" : "Apple airpods" }); Remove This will remove value from an array but not remove property key javascript Copy Ask AI // for single property suprsend . user . remove ( key , value ); suprsend . user . remove ( "wishlist" , "iphone12" ); // for multiple properties suprsend . user . remove ( property_obj ); suprsend . user . remove ({ "wishlist" : "iphone12" , "wishlist" : "Apple airpods" }); Increment Increase or decrease integer values on consecutive action, like login count. To reduce a property, provide a negative number for the value. javascript Copy Ask AI // for single property suprsend . user . increment ( key , value ); suprsend . user . increment ( "login_count" , 1 ); // for multiple properties suprsend . user . increment ( property_obj ); suprsend . user . increment ({ "login_count" : 1 , "order_count" : 1 }); // Sample values for incrementing a single property: // Sample values for incrementing multiple properties: Was this page helpful?

Glossary — Python 3.14.2 documentation Theme Auto Light Dark Previous topic Deprecations Next topic About this documentation This page Report a bug Show source Navigation index modules | next | previous | Python » 3.14.2 Documentation » Glossary | Theme Auto Light Dark | Glossary ¶ >>> ¶ The default Python prompt of the interactive shell. Often seen for code examples which can be executed interactively in the interpreter. ... ¶ Can refer to: The default Python prompt of the interactive shell when entering the code for an indented code block, when within a pair of matching left and right delimiters (parentheses, square brackets, curly braces or triple quotes), or after specifying a decorator. The three dots form of the Ellipsis object. abstract base class ¶ Abstract base classes complement duck-typing by providing a way to define interfaces when other techniques like hasattr() would be clumsy or subtly wrong (for example with magic methods ). ABCs introduce virtual subclasses, which are classes that don’t inherit from a class but are still recognized by isinstance() and issubclass() ; see the abc module documentation. Python comes with many built-in ABCs for data structures (in the collections.abc module), numbers (in the numbers module), streams (in the io module), import finders and loaders (in the importlib.abc module). You can create your own ABCs with the abc module. annotate function ¶ A function that can be called to retrieve the annotations of an object. This function is accessible as the __annotate__ attribute of functions, classes, and modules. Annotate functions are a subset of evaluate functions . annotation ¶ A label associated with a variable, a class attribute or a function parameter or return value, used by convention as a type hint . Annotations of local variables cannot be accessed at runtime, but annotations of global variables, class attributes, and functions can be retrieved by calling annotationlib.get_annotations() on modules, classes, and functions, respectively. See variable annotation , function annotation , PEP 484 , PEP 526 , and PEP 649 , which describe this functionality. Also see Annotations Best Practices for best practices on working with annotations. argument ¶ A value passed to a function (or method ) when calling the function. There are two kinds of argument: keyword argument : an argument preceded by an identifier (e.g. name= ) in a function call or passed as a value in a dictionary preceded by ** . For example, 3 and 5 are both keyword arguments in the following calls to complex() : complex ( real = 3 , imag = 5 ) complex ( ** { 'real' : 3 , 'imag' : 5 }) positional argument : an argument that is not a keyword argument. Positional arguments can appear at the beginning of an argument list and/or be passed as elements of an iterable preceded by * . For example, 3 and 5 are both positional arguments in the following calls: complex ( 3 , 5 ) complex ( * ( 3 , 5 )) Arguments are assigned to the named local variables in a function body. See the Calls section for the rules governing this assignment. Syntactically, any expression can be used to represent an argument; the evaluated value is assigned to the local variable. See also the parameter glossary entry, the FAQ question on the difference between arguments and parameters , and PEP 362 . asynchronous context manager ¶ An object which controls the environment seen in an async with statement by defining __aenter__() and __aexit__() methods. Introduced by PEP 492 . asynchronous generator ¶ A function which returns an asynchronous generator iterator . It looks like a coroutine function defined with async def except that it contains yield expressions for producing a series of values usable in an async for loop. Usually refers to an asynchronous generator function, but may refer to an asynchronous generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity. An asynchronous generator function may contain await expressions as well as async for , and async with statements. asynchronous generator iterator ¶ An object created by an asynchronous generator function. This is an asynchronous iterator which when called using the __anext__() method returns an awaitable object which will execute the body of the asynchronous generator function until the next yield expression. Each yield temporarily suspends processing, remembering the execution state (including local variables and pending try-statements). When the asynchronous generator iterator effectively resumes with another awaitable returned by __anext__() , it picks up where it left off. See PEP 492 and PEP 525 . asynchronous iterable ¶ An object, that can be used in an async for statement. Must return an asynchronous iterator from its __aiter__() method. Introduced by PEP 492 . asynchronous iterator ¶ An object that implements the __aiter__() and __anext__() methods. __anext__() must return an awaitable object. async for resolves the awaitables returned by an asynchronous iterator’s __anext__() method until it raises a StopAsyncIteration exception. Introduced by PEP 492 . atomic operation ¶ An operation that appears to execute as a single, indivisible step: no other thread can observe it half-done, and its effects become visible all at once. Python does not guarantee that high-level statements are atomic (for example, x += 1 performs multiple bytecode operations and is not atomic). Atomicity is only guaranteed where explicitly documented. See also race condition and data race . attached thread state ¶ A thread state that is active for the current OS thread. When a thread state is attached, the OS thread has access to the full Python C API and can safely invoke the bytecode interpreter. Unless a function explicitly notes otherwise, attempting to call the C API without an attached thread state will result in a fatal error or undefined behavior. A thread state can be attached and detached explicitly by the user through the C API, or implicitly by the runtime, including during blocking C calls and by the bytecode interpreter in between calls. On most builds of Python, having an attached thread state implies that the caller holds the GIL for the current interpreter, so only one OS thread can have an attached thread state at a given moment. In free-threaded builds of Python, threads can concurrently hold an attached thread state, allowing for true parallelism of the bytecode interpreter. attribute ¶ A value associated with an object which is usually referenced by name using dotted expressions. For example, if an object o has an attribute a it would be referenced as o.a . It is possible to give an object an attribute whose name is not an identifier as defined by Names (identifiers and keywords) , for example using setattr() , if the object allows it. Such an attribute will not be accessible using a dotted expression, and would instead need to be retrieved with getattr() . awaitable ¶ An object that can be used in an await expression. Can be a coroutine or an object with an __await__() method. See also PEP 492 . BDFL ¶ Benevolent Dictator For Life, a.k.a. Guido van Rossum , Python’s creator. binary file ¶ A file object able to read and write bytes-like objects . Examples of binary files are files opened in binary mode ( 'rb' , 'wb' or 'rb+' ), sys.stdin.buffer , sys.stdout.buffer , and instances of io.BytesIO and gzip.GzipFile . See also text file for a file object able to read and write str objects. borrowed reference ¶ In Python’s C API, a borrowed reference is a reference to an object, where the code using the object does not own the reference. It becomes a dangling pointer if the object is destroyed. For example, a garbage collection can remove the last strong reference to the object and so destroy it. Calling Py_INCREF() on the borrowed reference is recommended to convert it to a strong reference in-place, except when the object cannot be destroyed before the last usage of the borrowed reference. The Py_NewRef() function can be used to create a new strong reference . bytes-like object ¶ An object that supports the Buffer Protocol and can export a C- contiguous buffer. This includes all bytes , bytearray , and array.array objects, as well as many common memoryview objects. Bytes-like objects can be used for various operations that work with binary data; these include compression, saving to a binary file, and sending over a socket. Some operations need the binary data to be mutable. The documentation often refers to these as “read-write bytes-like objects”. Example mutable buffer objects include bytearray and a memoryview of a bytearray . Other operations require the binary data to be stored in immutable objects (“read-only bytes-like objects”); examples of these include bytes and a memoryview of a bytes object. bytecode ¶ Python source code is compiled into bytecode, the internal representation of a Python program in the CPython interpreter. The bytecode is also cached in .pyc files so that executing the same file is faster the second time (recompilation from source to bytecode can be avoided). This “intermediate language” is said to run on a virtual machine that executes the machine code corresponding to each bytecode. Do note that bytecodes are not expected to work between different Python virtual machines, nor to be stable between Python releases. A list of bytecode instructions can be found in the documentation for the dis module . callable ¶ A callable is an object that can be called, possibly with a set of arguments (see argument ), with the following syntax: callable ( argument1 , argument2 , argumentN ) A function , and by extension a method , is a callable. An instance of a class that implements the __call__() method is also a callable. callback ¶ A subroutine function which is passed as an argument to be executed at some point in the future. class ¶ A template for creating user-defined objects. Class definitions normally contain method definitions which operate on instances of the class. class variable ¶ A variable defined in a class and intended to be modified only at class level (i.e., not in an instance of the class). closure variable ¶ A free variable referenced from a nested scope that is defined in an outer scope rather than being resolved at runtime from the globals or builtin namespaces. May be explicitly defined with the nonlocal keyword to allow write access, or implicitly defined if the variable is only being read. For example, in the inner function in the following code, both x and print are free variables , but only x is a closure variable : def outer (): x = 0 def inner (): nonlocal x x += 1 print ( x ) return inner Due to the codeobject.co_freevars attribute (which, despite its name, only includes the names of closure variables rather than listing all referenced free variables), the more general free variable term is sometimes used even when the intended meaning is to refer specifically to closure variables. complex number ¶ An extension of the familiar real number system in which all numbers are expressed as a sum of a real part and an imaginary part. Imaginary numbers are real multiples of the imaginary unit (the square root of -1 ), often written i in mathematics or j in engineering. Python has built-in support for complex numbers, which are written with this latter notation; the imaginary part is written with a j suffix, e.g., 3+1j . To get access to complex equivalents of the math module, use cmath . Use of complex numbers is a fairly advanced mathematical feature. If you’re not aware of a need for them, it’s almost certain you can safely ignore them. concurrency ¶ The ability of a computer program to perform multiple tasks at the same time. Python provides libraries for writing programs that make use of different forms of concurrency. asyncio is a library for dealing with asynchronous tasks and coroutines. threading provides access to operating system threads and multiprocessing to operating system processes. Multi-core processors can execute threads and processes on different CPU cores at the same time (see parallelism ). concurrent modification ¶ When multiple threads modify shared data at the same time. Concurrent modification without proper synchronization can cause race conditions , and might also trigger a data race , data corruption, or both. context ¶ This term has different meanings depending on where and how it is used. Some common meanings: The temporary state or environment established by a context manager via a with statement. The collection of key­value bindings associated with a particular contextvars.Context object and accessed via ContextVar objects. Also see context variable . A contextvars.Context object. Also see current context . context management protocol ¶ The __enter__() and __exit__() methods called by the with statement. See PEP 343 . context manager ¶ An object which implements the context management protocol and controls the environment seen in a with statement. See PEP 343 . context variable ¶ A variable whose value depends on which context is the current context . Values are accessed via contextvars.ContextVar objects. Context variables are primarily used to isolate state between concurrent asynchronous tasks. contiguous ¶ A buffer is considered contiguous exactly if it is either C-contiguous or Fortran contiguous . Zero-dimensional buffers are C and Fortran contiguous. In one-dimensional arrays, the items must be laid out in memory next to each other, in order of increasing indexes starting from zero. In multidimensional C-contiguous arrays, the last index varies the fastest when visiting items in order of memory address. However, in Fortran contiguous arrays, the first index varies the fastest. coroutine ¶ Coroutines are a more generalized form of subroutines. Subroutines are entered at one point and exited at another point. Coroutines can be entered, exited, and resumed at many different points. They can be implemented with the async def statement. See also PEP 492 . coroutine function ¶ A function which returns a coroutine object. A coroutine function may be defined with the async def statement, and may contain await , async for , and async with keywords. These were introduced by PEP 492 . CPython ¶ The canonical implementation of the Python programming language, as distributed on python.org . The term “CPython” is used when necessary to distinguish this implementation from others such as Jython or IronPython. current context ¶ The context ( contextvars.Context object) that is currently used by ContextVar objects to access (get or set) the values of context variables . Each thread has its own current context. Frameworks for executing asynchronous tasks (see asyncio ) associate each task with a context which becomes the current context whenever the task starts or resumes execution. cyclic isolate ¶ A subgroup of one or more objects that reference each other in a reference cycle, but are not referenced by objects outside the group. The goal of the cyclic garbage collector is to identify these groups and break the reference cycles so that the memory can be reclaimed. data race ¶ A situation where multiple threads access the same memory location concurrently, at least one of the accesses is a write, and the threads do not use any synchronization to control their access. Data races lead to non-deterministic behavior and can cause data corruption. Proper use of locks and other synchronization primitives prevents data races. Note that data races can only happen in native code, but that native code might be exposed in a Python API. See also race condition and thread-safe . deadlock ¶ A situation in which two or more tasks (threads, processes, or coroutines) wait indefinitely for each other to release resources or complete actions, preventing any from making progress. For example, if thread A holds lock 1 and waits for lock 2, while thread B holds lock 2 and waits for lock 1, both threads will wait indefinitely. In Python this often arises from acquiring multiple locks in conflicting orders or from circular join/await dependencies. Deadlocks can be avoided by always acquiring multiple locks in a consistent order. See also lock and reentrant . decorator ¶ A function returning another function, usually applied as a function transformation using the @wrapper syntax. Common examples for decorators are classmethod() and staticmethod() . The decorator syntax is merely syntactic sugar, the following two function definitions are semantically equivalent: def f ( arg ): ... f = staticmethod ( f ) @staticmethod def f ( arg ): ... The same concept exists for classes, but is less commonly used there. See the documentation for function definitions and class definitions for more about decorators. descriptor ¶ Any object which defines the methods __get__() , __set__() , or __delete__() . When a class attribute is a descriptor, its special binding behavior is triggered upon attribute lookup. Normally, using a.b to get, set or delete an attribute looks up the object named b in the class dictionary for a , but if b is a descriptor, the respective descriptor method gets called. Understanding descriptors is a key to a deep understanding of Python because they are the basis for many features including functions, methods, properties, class methods, static methods, and reference to super classes. For more information about descriptors’ methods, see Implementing Descriptors or the Descriptor How To Guide . dictionary ¶ An associative array, where arbitrary keys are mapped to values. The keys can be any object with __hash__() and __eq__() methods. Called a hash in Perl. dictionary comprehension ¶ A compact way to process all or part of the elements in an iterable and return a dictionary with the results. results = {n: n ** 2 for n in range(10)} generates a dictionary containing key n mapped to value n ** 2 . See Displays for lists, sets and dictionaries . dictionary view ¶ The objects returned from dict.keys() , dict.values() , and dict.items() are called dictionary views. They provide a dynamic view on the dictionary’s entries, which means that when the dictionary changes, the view reflects these changes. To force the dictionary view to become a full list use list(dictview) . See Dictionary view objects . docstring ¶ A string literal which appears as the first expression in a class, function or module. While ignored when the suite is executed, it is recognized by the compiler and put into the __doc__ attribute of the enclosing class, function or module. Since it is available via introspection, it is the canonical place for documentation of the object. duck-typing ¶ A programming style which does not look at an object’s type to determine if it has the right interface; instead, the method or attribute is simply called or used (“If it looks like a duck and quacks like a duck, it must be a duck.”) By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance() . (Note, however, that duck-typing can be complemented with abstract base classes .) Instead, it typically employs hasattr() tests or EAFP programming. dunder ¶ An informal short-hand for “double underscore”, used when talking about a special method . For example, __init__ is often pronounced “dunder init”. EAFP ¶ Easier to ask for forgiveness than permission. This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements. The technique contrasts with the LBYL style common to many other languages such as C. evaluate function ¶ A function that can be called to evaluate a lazily evaluated attribute of an object, such as the value of type aliases created with the type statement. expression ¶ A piece of syntax which can be evaluated to some value. In other words, an expression is an accumulation of expression elements like literals, names, attribute access, operators or function calls which all return a value. In contrast to many other languages, not all language constructs are expressions. There are also statement s which cannot be used as expressions, such as while . Assignments are also statements, not expressions. extension module ¶ A module written in C or C++, using Python’s C API to interact with the core and with user code. f-string ¶ f-strings ¶ String literals prefixed with f or F are commonly called “f-strings” which is short for formatted string literals . See also PEP 498 . file object ¶ An object exposing a file-oriented API (with methods such as read() or write() ) to an underlying resource. Depending on the way it was created, a file object can mediate access to a real on-disk file or to another type of storage or communication device (for example standard input/output, in-memory buffers, sockets, pipes, etc.). File objects are also called file-like objects or streams . There are actually three categories of file objects: raw binary files , buffered binary files and text files . Their interfaces are defined in the io module. The canonical way to create a file object is by using the open() function. file-like object ¶ A synonym for file object . filesystem encoding and error handler ¶ Encoding and error handler used by Python to decode bytes from the operating system and encode Unicode to the operating system. The filesystem encoding must guarantee to successfully decode all bytes below 128. If the file system encoding fails to provide this guarantee, API functions can raise UnicodeError . The sys.getfilesystemencoding() and sys.getfilesystemencodeerrors() functions can be used to get the filesystem encoding and error handler. The filesystem encoding and error handler are configured at Python startup by the PyConfig_Read() function: see filesystem_encoding and filesystem_errors members of PyConfig . See also the locale encoding . finder ¶ An object that tries to find the loader for a module that is being imported. There are two types of finder: meta path finders for use with sys.meta_path , and path entry finders for use with sys.path_hooks . See Finders and loaders and importlib for much more detail. floor division ¶ Mathematical division that rounds down to nearest integer. The floor division operator is // . For example, the expression 11 // 4 evaluates to 2 in contrast to the 2.75 returned by float true division. Note that (-11) // 4 is -3 because that is -2.75 rounded downward . See PEP 238 . free threading ¶ A threading model where multiple threads can run Python bytecode simultaneously within the same interpreter. This is in contrast to the global interpreter lock which allows only one thread to execute Python bytecode at a time. See PEP 703 . free variable ¶ Formally, as defined in the language execution model , a free variable is any variable used in a namespace which is not a local variable in that namespace. See closure variable for an example. Pragmatically, due to the name of the codeobject.co_freevars attribute, the term is also sometimes used as a synonym for closure variable . function ¶ A series of statements which returns some value to a caller. It can also be passed zero or more arguments which may be used in the execution of the body. See also parameter , method , and the Function definitions section. function annotation ¶ An annotation of a function parameter or return value. Function annotations are usually used for type hints : for example, this function is expected to take two int arguments and is also expected to have an int return value: def sum_two_numbers ( a : int , b : int ) -> int : return a + b Function annotation syntax is explained in section Function definitions . See variable annotation and PEP 484 , which describe this functionality. Also see Annotations Best Practices for best practices on working with annotations. __future__ ¶ A future statement , from __future__ import <feature> , directs the compiler to compile the current module using syntax or semantics that will become standard in a future release of Python. The __future__ module documents the possible values of feature . By importing this module and evaluating its variables, you can see when a new feature was first added to the language and when it will (or did) become the default: >>> import __future__ >>> __future__ . division _Feature((2, 2, 0, 'alpha', 2), (3, 0, 0, 'alpha', 0), 8192) garbage collection ¶ The process of freeing memory when it is not used anymore. Python performs garbage collection via reference counting and a cyclic garbage collector that is able to detect and break reference cycles. The garbage collector can be controlled using the gc module. generator ¶ A function which returns a generator iterator . It looks like a normal function except that it contains yield expressions for producing a series of values usable in a for-loop or that can be retrieved one at a time with the next() function. Usually refers to a generator function, but may refer to a generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity. generator iterator ¶ An object created by a generator function. Each yield temporarily suspends processing, remembering the execution state (including local variables and pending try-statements). When the generator iterator resumes, it picks up where it left off (in contrast to functions which start fresh on every invocation). generator expression ¶ An expression that returns an iterator . It looks like a normal expression followed by a for clause defining a loop variable, range, and an optional if clause. The combined expression generates values for an enclosing function: >>> sum ( i * i for i in range ( 10 )) # sum of squares 0, 1, 4, ... 81 285 generic function ¶ A function composed of multiple functions implementing the same operation for different types. Which implementation should be used during a call is determined by the dispatch algorithm. See also the single dispatch glossary entry, the functools.singledispatch() decorator, and PEP 443 . generic type ¶ A type that can be parameterized; typically a container class such as list or dict . Used for type hints and annotations . For more details, see generic alias types , PEP 483 , PEP 484 , PEP 585 , and the typing module. GIL ¶ See global interpreter lock . global interpreter lock ¶ The mechanism used by the CPython interpreter to assure that only one thread executes Python bytecode at a time. This simplifies the CPython implementation by making the object model (including critical built-in types such as dict ) implicitly safe against concurrent access. Locking the entire interpreter makes it easier for the interpreter to be multi-threaded, at the expense of much of the parallelism afforded by multi-processor machines. However, some extension modules, either standard or third-party, are designed so as to release the GIL when doing computationally intensive tasks such as compression or hashing. Also, the GIL is always released when doing I/O. As of Python 3.13, the GIL can be disabled using the --disable-gil build configuration. After building Python with this option, code must be run with -X gil=0 or after setting the PYTHON_GIL=0 environment variable. This feature enables improved performance for multi-threaded applications and makes it easier to use multi-core CPUs efficiently. For more details, see PEP 703 . In prior versions of Python’s C API, a function might declare that it requires the GIL to be held in order to use it. This refers to having an attached thread state . global state ¶ Data that is accessible throughout a program, such as module-level variables, class variables, or C static variables in extension modules . In multi-threaded programs, global state shared between threads typically requires synchronization to avoid race conditions and data races . hash-based pyc ¶ A bytecode cache file that uses the hash rather than the last-modified time of the corresponding source file to determine its validity. See Cached bytecode invalidation . hashable ¶ An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() method). Hashable objects which compare equal must have the same hash value. Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally. Most of Python’s immutable built-in objects are hashable; mutable containers (such as lists or dictionaries) are not; immutable containers (such as tuples and frozensets) are only hashable if their elements are hashable. Objects which are instances of user-defined classes are hashable by default. They all compare unequal (except with themselves), and their hash value is derived from their id() . IDLE ¶ An Integrated Development and Learning Environment for Python. IDLE — Python editor and shell is a basic editor and interpreter environment which ships with the standard distribution of Python. immortal ¶ Immortal objects are a CPython implementation detail introduced in PEP 683 . If an object is immortal, its reference count is never modified, and therefore it is never deallocated while the interpreter is running. For example, True and None are immortal in CPython. Immortal objects can be identified via sys._is_immortal() , or via PyUnstable_IsImmortal() in the C API. immutable ¶ An object with a fixed value. Immutable objects include numbers, strings and tuples. Such an object cannot be altered. A new object has to be created if a different value has to be stored. They play an important role in places where a constant hash value is needed, for example as a key in a dictionary. Immutable objects are inherently thread-safe because their state cannot be modified after creation, eliminating concerns about improperly synchronized concurrent modification . import path ¶ A list of locations (or path entries ) that are searched by the path based finder for modules to import. During import, this list of locations usually comes from sys.path , but for subpackages it may also come from the parent package’s __path__ attribute. importing ¶ The process by which Python code in one module is made available to Python code in another module. importer ¶ An object that both finds and loads a module; both a finder and loader object. interactive ¶ Python has an interactive interpreter which means you can enter statements and expressions at the interpreter prompt, immediately execute them and see their results. Just launch python with no arguments (possibly by selecting it from your computer’s main menu). It is a very powerful way to test out new ideas or inspect modules and packages (remember help(x) ). For more on interactive mode, see Interactive Mode . interpreted ¶ Python is an interpreted language, as opposed to a compiled one, though the distinction can be blurry because of the presence of the bytecode compiler. This means that source files can be run directly without explicitly creating an executable which is then run. Interpreted languages typically have a shorter development/debug cycle than compiled ones, though their programs generally also run more slowly. See also interactive . interpreter shutdown ¶ When asked to shut down, the Python interpreter enters a special phase where it gradually releases all allocated resources, such as modules and various critical internal structures. It also makes several calls to the garbage collector . This can trigger the execution of code in user-defined destructors or weakref callbacks. Code executed during the shutdown phase can encounter various exceptions as the resources it relies on may not function anymore (common examples are library modules or the warnings machinery). The main reason for interpreter shutdown is that the __main__ module or the script being run has finished executing. iterable ¶ An object capable of returning its members one at a time. Examples of iterables include all sequence types (such as list , str , and tuple ) and some non-sequence types like dict , file objects , and objects of any classes you define with an __iter__() method or with a __getitem__() method that implements sequence semantics. Iterables can be used in a for loop and in many other places where a sequence is needed ( zip() , map() , …). When an iterable object is passed as an argument to the built-in function iter() , it returns an iterator for the object. This iterator is good for one pass over the set of values. When using iterables, it is usually not necessary to call iter() or deal with iterator objects yourself. The for statement does that automatically for you, creating a temporary unnamed variable to hold the iterator for the duration of the loop. See also iterator , sequence , and generator . iterator ¶ An object representing a stream of data. Repeated calls to the iterator’s __next__() method (or passing it to the built-in function next() ) return successive items in the stream. When no more data are available a StopIteration exception is raised instead. At this point, the iterator object is exhausted and any further calls to its __next__() method just raise StopIteration again. Iterators are required to have an __iter__() method that returns the iterator object itself so every iterator is also iterable and may be used in most places where other iterables are accepted. One notable exception is code which attempts multiple iteration passes. A container object (such as a list ) produces a fresh new iterator each time you pass it to the iter() function or use it in a for loop. Attempting this with an iterator will just return the same exhausted iterator object used in the previous iteration pass, making it appear like an empty container. More information can be found in Iterator Types . CPython implementation detail: CPython does not consistently apply the requirement that an iterator define __iter__() . And also please note that free-threaded CPython does not guarantee thread-safe behavior of iterator operations. key function ¶ A key function or collation function is a callable that returns a value used for sorting or ordering. For example, locale.strxfrm() is used to produce a sort key that is aware of locale specific sort conventions. A number of tools in Python accept key functions to control how elements are ordered or grouped. They include min() , max() , sorted() , list.sort() , heapq.merge() , heapq.nsmallest() , heapq.nlargest() , and itertools.groupby() . There are several ways to create a key function. For example. the str.casefold() method can serve as a key function for case insensitive sorts. Alternatively, a key function can be built from a lambda expression such as lambda r: (r[0], r[2]) . Also, operator.attrgetter() , operator.itemgetter() , and operator.methodcaller() are three key function constructors. See the Sorting HOW TO for examples of how to create and use key functions. keyword argument ¶ See argument . lambda ¶ An anonymous inline function consisting of a single expression which is evaluated when the function is called. The syntax to create a lambda function is lambda [parameters]: expression LBYL ¶ Look before you leap. This coding style explicitly tests for pre-conditions before making calls or lookups. This style contrasts with the EAFP approach and is characterized by the presence of many if statements. In a multi-threaded environment, the LBYL approach can risk introducing a race condition between “the looking” and “the leaping”. For example, the code, if key in mapping: return mapping[key] can fail if another thread removes key from mapping after the test, but before the lookup. This issue can be solved with locks or by using the EAFP approach. See also thread-safe . lexical analyzer ¶ Formal name for the tokenizer ; see token . list ¶ A built-in Python sequence . Despite its name it is more akin to an array in other languages than to a linked list since access to elements is O (1). list comprehension ¶ A compact way to process all or part of the elements in a sequence and return a list with the results. result = ['{:#04x}'.format(x) for x in range(256) if x % 2 == 0] generates a list of strings containing even hex numbers (0x..) in the range from 0 to 255. The if clause is optional. If omitted, all elements in range(256) are processed. lock ¶ A synchronization primitive that allows only one thread at a time to access a shared resource. A thread must acquire a lock before accessing the protected resource and release it afterward. If a thread attempts to acquire a lock that is already held by another thread, it will block until the lock becomes available. Python’s threading module provides Lock (a basic lock) and RLock (a reentrant lock). Locks are used to prevent race conditions and ensure thread-safe access to shared data. Alternative design patterns to locks exist such as queues, producer/consumer patterns, and thread-local state. See also deadlock , and reentrant . loader ¶ An object that loads a module. It must define the exec_module() and create_module() methods to implement the Loader interface. A loader is typically returned by a finder . See also: Finders and loaders importlib.abc.Loader PEP 302 locale encoding ¶ On Unix, it is the encoding of the LC_CTYPE locale. It can be set with locale.setlocale(locale.LC_CTYPE, new_locale) . On Windows, it is the ANSI code page (ex: "cp1252" ). On Android and VxWorks, Python uses "utf-8" as the locale encoding. locale.getencoding() can be used to get the locale encoding. See also the filesystem encoding and error handler . magic method ¶ An informal synonym for special method . mapping ¶ A container object that supports arbitrary key lookups and implements the methods specified in the collections.abc.Mapping or collections.abc.MutableMapping abstract base classes . Examples include dict , collections.defaultdict , collections.OrderedDict and collections.Counter . meta path finder ¶ A finder returned by a search of sys.meta_path . Meta path finders are related to, but different from path entry finders . See importlib.abc.MetaPathFinder for the methods that meta path finders implement. metaclass ¶ The class of a class. Class definitions create a class name, a class dictionary, and a list of base classes. The metaclass is responsible for taking those three arguments and creating the class. Most object oriented programming languages provide a default implementation. What makes Python special is that it is possible to create custom metaclasses. Most users never need this tool, but when the need arises, metaclasses can provide powerful, elegant solutions. They have been used for logging attribute access, adding thread-safety, tracking object creation, implementing singletons, and many other tasks. More information can be found in Metaclasses . method ¶ A function which is defined inside a class body. If called as an attribute of an instance of that class, the method will get the instance object as its first argument (which is usually called self ). See function and nested scope . method resolution order ¶ Method Resolution Order is the order in which base classes are searched for a member during lookup. See The Python 2.3 Method Resolution Order for details of the algorithm used by the Python interpreter since the 2.3 release. module ¶ An object that serves as an organizational unit of Python code. Modules have a namespace containing arbitrary Python objects. Modules are loaded into Python by the process of importing . See also package . module spec ¶ A namespace containing the import-related information used to load a module. An instance of importlib.machinery.ModuleSpec . See also Module specs . MRO ¶ See method resolution order . mutable ¶ An object with state that is allowed to change during the course of the program. In multi-threaded programs, mutable objects that are shared between threads require careful synchronization to avoid race conditions . See also immutable , thread-safe , and concurrent modification . named tuple ¶ The term “named tuple” applies to any type or class that inherits from tuple and whose indexable elements are also accessible using named attributes. The type or class may have other features as well. Several built-in types are named tuples, including the values returned by time.localtime() and os.stat() . Another example is sys.float_info : >>> sys . float_info [ 1 ] # indexed access 1024 >>> sys . float_info . max_exp # named field access 1024 >>> isinstance ( sys . float_info , tuple ) # kind of tuple True Some named tuples are built-in types (such as the above examples). Alternatively, a named tuple can be created from a regular class definition that inherits from tuple and that defines named fields. Such a class can be written by hand, or it can be created by inheriting typing.NamedTuple , or with the factory function collections.namedtuple() . The latter techniques also add some extra methods that may not be found in hand-written or built-in named tuples. namespace ¶ The place where a variable is stored. Namespaces are implemented as dictionaries. There are the local, global and built-in namespaces as well as nested namespaces in objects (in methods). Namespaces support modularity by preventing naming conflicts. For instance, the functions builtins.open and os.open() are distinguished by their namespaces. Namespaces also aid readability and maintainability by making it clear which module implements a function. For instance, writing random.seed() or itertools.islice() makes it clear that those functions are implemented by the random and itertools modules, respectively. namespace package ¶ A package which serves only as a container for subpackages. Namespace packages may have no physical representation, and specifically are not like a regular package because they have no __init__.py file. Namespace packages allow several individually installable packages to have a common parent package. Otherwise, it is recommended to use a regular package . For more information, see PEP 420 and Namespace packages . See also module . native code ¶ Code that is compiled to machine instructions and runs directly on the processor, as opposed to code that is interpreted or runs in a virtual machine. In the context of Python, native code typically refers to C, C++, Rust or Fortran code in extension modules that can be called from Python. See also extension module . nested scope ¶ The ability to refer to a variable in an enclosing definition. For instance, a function defined inside another function can refer to variables in the outer function. Note that nested scopes by default work only for reference and not for assignment. Local variables both read and write in the innermost scope. Likewise, global variables read and write to the global namespace. The nonlocal allows writing to outer scopes. new-style class ¶ Old name for the flavor of classes now used for all class objects. In earlier Python versions, only new-style classes could use Python’s newer, versatile features like __slots__ , descriptors, properties, __getattribute__() , class methods, and static methods. non-deterministic ¶ Behavior where the outcome of a program can vary between executions with the same inputs. In multi-threaded programs, non-deterministic behavior often results from race conditions where the relative timing or interleaving of threads affects the result. Proper synchronization using locks and other synchronization primitives helps ensure deterministic behavior. object ¶ Any data with state (attributes or value) and defined behavior (methods). Also the ultimate base class of any new-style class . optimized scope ¶ A scope where target local variable names are reliably known to the compiler when the code is compiled, allowing optimization of read and write access to these names. The local namespaces for functions, generators, coroutines, comprehensions, and generator expressions are optimized in this fashion. Note: most interpreter optimizations are applied to all scopes, only those relying on a known set of local and nonlocal variable names are restricted to optimized scopes. optional module ¶ An extension module that is part of the standard library , but may be absent in some builds of CPython , usually due to missing third-party libraries or because the module is not available for a given platform. See Requirements for optional modules for a list of optional modules that require third-party libraries. package ¶ A Python module which can contain submodules or recursively, subpackages. Technically, a package is a Python module with a __path__ attribute. See also regular package and namespace package . parallelism ¶ Executing multiple operations at the same time (e.g. on multiple CPU cores). In Python builds with the global interpreter lock (GIL) , only one thread runs Python bytecode at a time, so taking advantage of multiple CPU cores typically involves multiple processes (e.g. multiprocessing ) or native extensions that release the GIL. In free-threaded Python, multiple Python threads can run Python code simultaneously on different cores. parameter ¶ A named entity in a function (or method) definition that specifies an argument (or in some cases, arguments) that the function can accept. There are five kinds of parameter: positional-or-keyword : specifies an argument that can be passed either positionally or as a keyword argument . This is the default kind of parameter, for example foo and bar in the following: def func ( foo , bar = None ): ... positional-only : specifies an argument that can be supplied only by position. Positional-only parameters can be defined by including a / character in the parameter list of the function definition after them, for example posonly1 and posonly2 in the following: def func ( posonly1 , posonly2 , / , positional_or_keyword ): ... keyword-only : specifies an argument that can be supplied only by keyword. Keyword-only parameters can be defined by including a single var-positional parameter or bare * in the parameter list of the function definition before them, for example kw_only1 and kw_only2 in the following: def func ( arg , * , kw_only1 , kw_only2 ): ... var-positional : specifies that an arbitrary sequence of positional arguments can be provided (in addition to any positional arguments already accepted by other parameters). Such a parameter can be defined by prepending the parameter name with * , for example args in the following: def func ( * args , ** kwargs ): ... var-keyword : specifies that arbitrarily many keyword arguments can be provided (in addition to any keyword arguments already accepted by other parameters). Such a parameter can be defined by prepending the parameter name with ** , for example kwargs in the example above. Parameters can specify both optional and required arguments, as well as default values for some optional arguments. See also the argument glossary entry, the FAQ question on the difference between arguments and parameters , the inspect.Parameter class, the Function definitions section, and PEP 362 . path entry ¶ A single location on the import path which the path based finder consults to find modules for importing. path entry finder ¶ A finder returned by a callable on sys.path_hooks (i.e. a path entry hook ) which knows how to locate modules given a path entry . See importlib.abc.PathEntryFinder for the methods that path entry finders implement. path entry hook ¶ A callable on the sys.path_hooks list which returns a path entry finder if it knows how to find modules on a specific path entry . path based finder ¶ One of the default meta path finders which searches an import path for modules. path-like object ¶ An object representing a file system path. A path-like object is either a str or bytes object representing a path, or an object implementing the os.PathLike protocol. An object that supports the os.PathLike protocol can be converted to a str or bytes file system path by calling the os.fspath() function; os.fsdecode() and os.fsencode() can be used to guarantee a str or bytes result instead, respectively. Introduced by PEP 519 . PEP ¶ Python Enhancement Proposal. A PEP is a design document providing information to the Python community, or describing a new feature for Python or its processes or environment. PEPs should provide a concise technical specification and a rationale for proposed features. PEPs are intended to be the primary mechanisms for proposing major new features, for collecting community input on an issue, and for documenting the design decisions that have gone into Python. The PEP author is responsible for building consensus within the community and documenting dissenting opinions. See PEP 1 . portion ¶ A set of files in a single directory (possibly stored in a zip file) that contribute to a namespace package, as defined in PEP 420 . positional argument ¶ See argument . provisional API ¶ A provisional API is one which has been deliberately excluded from the standard library’s backwards compatibility guarantees. While major changes to such interfaces are not expected, as long as they are marked provisional, backwards incompatible changes (up to and including removal of the interface) may occur if deemed necessary by core developers. Such changes will not be made

React 官方中文文档 React v 19.2 搜索 ⌘ Ctrl K 教程 参考 社区 博客 React 用于构建 Web 和原生交互界面的库 学习 React API 参考 用组件创建用户界面 React 让你可以通过组件来构建用户界面。你可以创建像 Thumbnail 、 LikeButton 和 Video 这样的组件。然后将它们组合成整个应用程序。 Video.js function Video ( { video } ) { return ( < div > < Thumbnail video = { video } /> < a href = { video . url } > < h3 > { video . title } </ h3 > < p > { video . description } </ p > </ a > < LikeButton video = { video } /> </ div > ) ; } My video Video description 无论你是独自工作还是与成千上万的其他开发人员合作,使用 React 的感觉都是相同的。它旨在让你轻松地组合由独立开发者、团队或组织编写的组件。 用代码和标签编写组件 React 组件是 JavaScript 函数。想要有条件地显示一些内容吗?使用 if 语句。 想要展示一个列表?尝试使用数组的 map() 方法。学习 React 就是学习编程。 VideoList.js function VideoList ( { videos , emptyHeading } ) { const count = videos . length ; let heading = emptyHeading ; if ( count > 0 ) { const noun = count > 1 ? 'Videos' : 'Video' ; heading = count + ' ' + noun ; } return ( < section > < h2 > { heading } </ h2 > { videos . map ( video => < Video key = { video . id } video = { video } /> ) } </ section > ) ; } 3 Videos First video Video description Second video Video description Third video Video description 这种标签语法被称为 JSX。它是由 React 推广的 JavaScript 语法扩展。将 JSX 标签与相关的渲染逻辑放在一起,使得创建、维护和删除 React 组件变得容易。 在任何地方添加交互 React 组件接收数据并返回应该出现在屏幕上的内容。你可以通过响应交互(例如用户输入)向它们传递新数据。然后,React 将更新屏幕以匹配新数据。 SearchableVideoList.js import { useState } from 'react' ; function SearchableVideoList ( { videos } ) { const [ searchText , setSearchText ] = useState ( '' ) ; const foundVideos = filterVideos ( videos , searchText ) ; return ( < > < SearchInput value = { searchText } onChange = { newText => setSearchText ( newText ) } /> < VideoList videos = { foundVideos } emptyHeading = { `No matches for “ ${ searchText } ”` } /> </ > ) ; } example.com / videos.html React Videos A brief history of React Search 5 Videos React: The Documentary The origin story of React Rethinking Best Practices Pete Hunt (2013) Introducing React Native Tom Occhino (2015) Introducing React Hooks Sophie Alpert and Dan Abramov (2018) Introducing Server Components Dan Abramov and Lauren Tan (2020) 你也可以不用 React 去构建整个页面,而只是将 React 添加到现有的 HTML 页面中,在任何地方呈现交互式的 React 组件。 将 React 添加到你已有的页面中 使用框架 进行全栈开发 React 是一个库。它允许你将组件放在一起,但不关注路由和数据获取。要使用 React 构建整个应用程序,我们建议使用像 Next.js 或 React Router 这样的全栈 React 框架。 confs/[slug].js import { db } from './database.js' ; import { Suspense } from 'react' ; async function ConferencePage ( { slug } ) { const conf = await db .

OpenAI Open in ChatGPT Learn about SuprSend and how you can use it to power multi-channel product notifications. OpenAI Open in ChatGPT SuprSend has all the features set which enable you to send notifications in a reliable and scalable manner, as well as take care of end-user experience, thereby eliminating the need to build any notification service in-house. ​ Benefits of using SuprSend as your notification stack: You do not have to do any vendor integrations for channels in your code. You can easily add/remove/prioritise vendors and channels from your SuprSend account, You can design powerful templates for all channels together and manage them from a single place, You can leverage powerful features to experiment fast with notifications as well as take care of end user experience without writing a single line of code. ​ Introduction to Workflows Communications are made up of multiple components - trigger, logic, content, variables, target user, channels, vendors, etc. Typical communication solutions have one or more components intertwined with each other. SuprSend solves communications from a different and more powerful approach, which we call Workflows. At SuprSend, all the constituent components are decoupled from each other, making it modular in nature. The components can come from any source. All these components are configured as nodes in Workflows, where the processing happens for delivery and optimisation. This allows Workflows to handle any complexity possible in your communication use cases. ​ How do you trigger notifications? You can trigger notifications in one of the two ways: Send events to SuprSend from your frontend clients (android app, website, etc) via SuprSend Client SDK, and create a Workflow on SuprSend platform to trigger notification on an event. Create workflow and trigger notification from your backend itself using an omni-channel HTTPS API method, or you can use our Backend SDK. All the other components (like vendors, templates, optimisation, scaling, etc.) are created and managed on SuprSend platform. You can check the ‘Core Concepts’ section that lists down the components used in the platform, so you can navigate the platform and use all the features with ease. ​ SuprSend APIs You can try out SuprSend APIs from our Postman collection Was this page helpful?
