Choosing the right email-delivery service means balancing deliverability, pricing, API/SMTP flexibility, analytics, and compliance. Below we compare five leading platforms. Amazon SES (Simple Email Service) Key Features: High-volume email sending, both SMTP and API endpoints; integrates deeply with the Amazon Web Services ecosystem; global infrastructure; flexible developer tooling. Cost: Extremely competitive: e.g., when sending from EC2 or AWS Lambda the first 62,000 emails/month are free, then ~$0.10 per 1,000 emails; attachments and data transfer may add. Security: Built on AWS infrastructure; supports DKIM, SPF, dedicated IPs, feedback loops, encryption in transit and at rest; compliance with AWS standard certifications. Postmark Key Features: Focused on transactional email (as opposed to just bulk newsletters); fast delivery, high deliverability, good analytics and webhooks for opens, clicks, bounces. Cost: Pricing tiers based on volume; e.g., starting plans around ~10,000 emails/month for ~$10-$20, then incremental cost as volume rises. Security: Dedicated IP options, DKIM/SPF support, strong reputation management; suitable for mission-critical transactional workflows. SendGrid Key Features: API + SMTP support, large ecosystem, supports transactional + marketing email, advanced analytics, templating, and large partner ecosystem. Cost: Free tier often available (e.g., send up to 100 emails/day), then paid plans starting ~$15-$20/month for higher volumes; additional cost for dedicated IPs, extra features. Security: Supports DKIM, SPF, dedicated IPs, sub-users, role-based access controls, SOC2/ISO certifications (depends on plan), and advanced deliverability tools. SMTP.com Key Features: Established SMTP relay service, good for both transactional and marketing email, supports dedicated IPs, deliverability consulting, reputation monitoring. Cost: Pricing typically starts with a base plan (e.g., ~50,000-100,000 emails/month) and scales with volume; dedicated IPs extra. Security: Offers dedicated sending infrastructure, monitoring, authentication features, reputation management support. Mailgun Key Features: Developer-centric email API, SMTP relay, high deliverability, inbound routing (webhooks for incoming email), analytics, and event webhooks for opens, clicks. Cost: Pay-as-you-go model: e.g., first 5,000 emails free/month (in some tiers), then ~$0.80-$1 per 1,000 emails; dedicated IPs and premium features extra. Security: Supports DKIM, SPF, dedicated IPs, two-factor authentication, API keys, strong event logging; used by tech teams requiring deep integration. Which Platform Fits Your Use-Case? Budget-conscious / AWS-native infrastructure: Choose Amazon SES - lowest cost per email if you’re comfortable managing infrastructure and deliverability. Transactional-only, high reliability: Postmark is ideal if you send notifications, password resets, receipt emails, and want very high deliverability without marketing-bulk overhead. All-in-one (transactional + marketing) with ecosystem: SendGrid offers breadth of features and is good if you’ll scale into marketing workflows beyond pure transactional email. Established SMTP relay + deliverability consulting: SMTP.com fits organizations that want a trusted relay, dedicated IPs, and expert deliverability support. Developer-centric, API-first, inbound + outbound email flows: Mailgun is strong when you need programmatic control, inbound routing, analytics, and integration with microservice architectures. Conclusion Selecting the right email delivery platform depends on your volume, type of email (transactional vs marketing), budget, infrastructure, and deliverability goals. Each of the platforms above has distinct strengths: aligning them with your use-case ensures you get reliability, cost-efficiency, and future scalability.

If you’re interested in learning more, get started at highlight.io . OpenTelemetry is an important specification that defines how we send telemetry data to observability backends like Highlight.io, Grafana, and others. OpenTelemetry is great because it is vendor agnostic, and can be used with several observability backends. If you're new to OpenTelemetry, you can learn more about it here . Today, we'll go through a complete guide to using OpenTelemetry in Python, including the high-level concepts as well as how to send traces and logs to your OpenTelemetry backend of choice. Step One: Signals In OpenTelemetry, a signal is a type of telemetry data that is collected and sent to an observability backend. There are three primary types of signals in OpenTelemetry: traces, metrics, and logs. Traces : Traces represent the end-to-end journey of a request as it travels through various services and components in a distributed system. They are composed of spans, which are individual units of work within the trace. Traces help you understand the flow of requests and identify performance bottlenecks or errors in your system. Metrics : Metrics are numerical measurements that provide insights into the performance and health of your system. They can include data such as request counts, error rates, and latency. Metrics are typically aggregated over time and used to monitor trends and set up alerts. Logs : Logs are timestamped records of events that occur within your application. They provide detailed information that is helpful for monitoring, debugging and troubleshooting the application's behavior. Logs can include various levels of severity, such as info, warning, and error. In addition to traces, metrics and logs, there are other constructs that can inherit from a signal. For example, an error can be represented using traces as the underlying data type, providing context about where and why the error occurred. Similarly, sessions can be constructed using several signals, such as traces, metrics, and logs, to provide a holistic view of a user's interaction with the system. In the context of OpenTelemetry, signals are generated by instrumenting your systems (whether its a container, application, or service). Components of Instrumentation Beyond signals, when working with OpenTelemetry instrumented in your application code, there are several key components that ultimately make up the OpenTelemetry API. These components are designed to be flexible and can be used for all signals. After these signals leave your application, they then can hit an OpenTelemetry collector (or multiple). In Highlight, we host a cluster of collectors that can be used to send data to, but you can also choose to host your own. Let's go through each of them. You can refer to the diagram below for a visual representation of how these components interact: Provider A provider is the API entry point that holds the configuration for telemetry data. In the context of tracing, this would be a TracerProvider , and for logging, it would be a LoggerProvider . The provider is responsible for setting up the environment and ensuring that all necessary configurations are in place. This can include configuring a vendor specific api key, or something as simple as setting the service name and environment. For example, a TracerProvider could set up the resource attributes like service name and environment, and set the Highlight project id so that the traces are associated with your Highlight project. Here's a quick example of what this looks like in code: from opentelemetry import trace from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.resources import Resource provider = TracerProvider(resource=Resource.create( { "service.name": "my-service", "highlight.project_id": "<YOUR_PROJECT_ID>", "environment": "production", } )) trace.set_tracer_provider(provider) tracer = trace.get_tracer("my-service") Processor A processor defines any pre-processing that should be done on the created signals, such as batching, sampling, filtering or even enriching data. This is important because you may have specific needs on the machine that you're sending data from that require customization. As a very simple example, a BatchSpanProcessor collects spans in batches and sends them to the exporter, which is more efficient than sending each span individually. Here's an example of how you might configure a BatchSpanProcessor : from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.trace.export import BatchSpanProcessor from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter processor = BatchSpanProcessor( exporter=OTLPSpanExporter(endpoint="https://otel.highlight.io:4317"), max_queue_size=1000, max_export_batch_size=100, schedule_delay_millis=1000, ) As you can see, we've configured the processor to use a BatchSpanProcessor with an OTLPSpanExporter that sends the spans to the Highlight collector (more about this later). We've also configured the processor to batch the spans and send them to the exporter every second with a queue size of 1000. Exporter Finally, an exporter sends the telemetry data to the backend. This is where you configure the endpoint and any other necessary settings related to the backend you're sending data to. For example, an OTLPSpanExporter would configure the endpoint and any necessary headers, while an ConsoleSpanExporter would simply print the spans to the console. Here's an example of how you might configure an OTLPSpanExporter : from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter exporter = OTLPSpanExporter(endpoint="https://otel.highlight.io:4317", insecure=True, headers={ "foo": "bar" }) As you can see, we've configured the exporter to use the Highlight collector, and set the foo header to bar . Try Highlight Today Get the visibility you need Get started for free Instrumenting your application Logging Now that we're familiar with the high-level concepts, let's see how we can instrument our application to send logs to an OpenTelemetry backend. In this example, we'll assume that we're sending data to Highlight.io, but the same principles would apply to any other backend that supports OpenTelemetry. First, lets install the necessary packages: pip install opentelemetry-api opentelemetry-sdk opentelemetry-exporter-otlp Next, we'll need to set up the provider, processor, and exporter. service_name = "my-service" environment = "production" otel_endpoint = "https://otel.highlight.io:4317" # Set up the logger provider with the resource logger_provider = LoggerProvider(resource=Resource.create( { "service.name": service_name, "highlight.project_id": "<YOUR_PROJECT_ID>", "environment": environment, } )) set_logger_provider(logger_provider) # Configure the OTLP log exporter exporter = OTLPLogExporter(endpoint=otel_endpoint, insecure=True) logger_provider.add_log_record_processor(BatchLogRecordProcessor(exporter)) # Set up the logger logger = logging.getLogger(service_name) logger.setLevel(logging.DEBUG) # Add the OpenTelemetry logging handler handler = LoggingHandler(level=logging.DEBUG, logger_provider=logger_provider) logger.addHandler(handler) Tracing Similar to logging, we can instrument our application to send traces to an OpenTelemetry backend. Lets start with installing the necessary packages: pip install opentelemetry-api opentelemetry-sdk opentelemetry-exporter-otlp Next, we'll need to set up the provider, processor, and exporter. import logging from opentelemetry import trace from opentelemetry._logs import set_logger_provider from opentelemetry.exporter.otlp.proto.grpc._log_exporter import OTLPLogExporter from opentelemetry.sdk._logs import LoggerProvider, LoggingHandler from opentelemetry.sdk._logs.export import BatchLogRecordProcessor from opentelemetry.sdk.resources import Resource from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.trace.export import BatchSpanProcessor from opentelemetry.sdk.trace.export import ConsoleSpanExporter from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter import sys # Define the service name and environment service_name = "my-service" environment = "production" otel_endpoint = "https://otel.highlight.io:4317" # Create a resource with service name and highlight project ID provider = TracerProvider(resource=Resource.create( { "service.name": service_name, "highlight.project_id": "<YOUR_PROJECT_ID>", "environment": environment, } )) processor = BatchSpanProcessor(OTLPSpanExporter(endpoint=otel_endpoint, insecure=True)) provider.add_span_processor(processor) trace.set_tracer_provider(provider) tracer = trace.get_tracer(service_name) At this point, once you've instrumented your application to send logs and traces to an OpenTelemetry backend, you can start using the tracer and logger objects to start sending data to your backend, like so: with tracer.start_as_current_span("example-span") as span: logger.info('hello, world!') span.set_attributes( { "category": "special", "rows_affected": 123 } ) logger.warning('whoa there', {'key': 'value'})`, Metrics Lastly, we can instrument our application to send metrics. In this example, we'll send a simple count metric, but you can also send other types of metrics like histograms, gauges, and more (see the OpenTelemetry docs for more information). First, we need to install the necessary OpenTelemetry packages for metrics: pip install opentelemetry-api opentelemetry-sdk opentelemetry-exporter-otlp Next, we'll need to set up the provider, processor, and exporter. from opentelemetry import metrics from opentelemetry.sdk.metrics import MeterProvider, set_meter_provider from opentelemetry.sdk.metrics.export import ConsoleMetricsExporter from opentelemetry.sdk.resources import Resource # Set up the meter provider with the resource meter_provider = MeterProvider(resource=Resource.create( { "service.name": service_name, "highlight.project_id": "<YOUR_PROJECT_ID>", "environment": environment, } )) set_meter_provider(meter_provider) meter = metrics.get_meter("my-service") counter = meter.create_counter("my-counter") And lastly, we can use the meter to create a counter and add a simple value to it: counter.add(1) Note that this is a simple example, and you can also create other types of metrics like histograms, gauges, and more. There's also the option to use Observable Metric Objects, which allow for more complex metrics collection (like collecting CPU usage, memory usage, etc). Take a look at the OpenTelemetry docs for more information. Auto-instrumentation & Middleware Last but not least, in addition to manual instrumentation, OpenTelemetry also supports auto-instrumentation for popular libraries and frameworks. This allows you to automatically collect telemetry data without having to modify your application code. For example, in Python, you could use the OpenTelemetry Distro SDK or the Zero Code Python setup to automatically instrument your application. The downside of these options, however, is that it requires that you change the way your application is run (and may affect your deployment strategy). As a good alternative, you could use middleware to automatically instrument your application. Middleware is a layer of code that sits between your application and the OpenTelemetry backend, and can be used to automatically collect telemetry data. For example, in a Python FastAPI application, you could write a simple middleware to wrap your application and automatically create traces for each request, like so: from fastapi import Request, FastAPI app = FastAPI() @app.middleware("http") async def trace_middleware(request, call_next): with tracer.start_as_current_span(f"{request.method} {request.url.path}"): response = await call_next(request) return response @app.get("/") def read_root(): return {"message": "Hello, World!"} The great thing about middleware is that it doesn't require that you change the way your application is run, and everytime you write signals within each of your endpoints, you'll automatically have traces and logs associated with that request. Putting it all together Let's take the various pieces of the OpenTelemetry configuration and put them into a single file that can easily be imported by our application. Create the file o11y.py with the following contents: import logging import os from dotenv import load_dotenv from typing import Optional from opentelemetry import metrics, trace from opentelemetry.sdk.metrics.export import AggregationTemporality from opentelemetry.sdk.metrics import Counter, Histogram, UpDownCounter from opentelemetry._logs import set_logger_provider from opentelemetry.exporter.otlp.proto.grpc._log_exporter import OTLPLogExporter from opentelemetry.exporter.otlp.proto.grpc.metric_exporter import OTLPMetricExporter from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter from opentelemetry.sdk._logs import LoggerProvider, LoggingHandler from opentelemetry.sdk._logs.export import BatchLogRecordProcessor, ConsoleLogExporter from opentelemetry.sdk.metrics import MeterProvider from opentelemetry.sdk.metrics.export import ConsoleMetricExporter, PeriodicExportingMetricReader from opentelemetry.sdk.resources import Resource from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.trace.export import BatchSpanProcessor, ConsoleSpanExporter EXPORTER_OTLP_ENDPOINT = os.getenv("OTEL_ENDPOINT","https://otel.highlight.io:4317") # read from .env load_dotenv() print("OTEL Endpoint is: ", EXPORTER_OTLP_ENDPOINT) HIGHLIGHT_PROJECT_ID = os.getenv("HIGHLIGHT_PROJECT_ID", "EMPTY") print("HIGHLIGHT_PROJECT_ID is: ", HIGHLIGHT_PROJECT_ID) import sys def create_logger(service_name: str, environment: Optional[str] = "production", local_debug: bool = False) -> logging.Logger: if environment is None: environment = "production" commit = os.getenv("RENDER_GIT_COMMIT", "unknown") resource = Resource.create( { "service.name": service_name, "highlight.project_id": HIGHLIGHT_PROJECT_ID, "environment": environment, "commit": commit } ) logger_provider = LoggerProvider(resource=resource) set_logger_provider(logger_provider) exporter = OTLPLogExporter(endpoint=EXPORTER_OTLP_ENDPOINT, insecure=True) if not local_debug else ConsoleLogExporter() logger_provider.add_log_record_processor(BatchLogRecordProcessor(exporter)) logger = logging.getLogger(service_name) logger.setLevel(logging.DEBUG) handler = LoggingHandler(level=logging.DEBUG, logger_provider=logger_provider) logger.addHandler(handler) # Add console handler for stdout console_handler = logging.StreamHandler(sys.stdout) console_handler.setLevel(logging.DEBUG) if commit: formatter = logging.Formatter('commit: ' + commit + ' -

This version of the Terms of Service will go into effect on January 15, 2026. Until then, the current Terms of Service continue to apply. Summary of our Terms These Terms of Service (“Terms”) are part of the User Agreement – a legally binding contract governing your relationship with X. You should read these Terms in full, but here are a few key things you should take away: You will see advertising on the platform: In exchange for accessing the Services, X and our third-party providers and partners may display advertising to you. When posting Content and otherwise using the Services, you must comply with this User Agreement and Applicable Law: You are responsible for your use of the Services and your Content. You must comply with the User Agreement, including all applicable policies and rules, and all applicable laws. You must abide by the Services’ acceptable use terms: You may not access the Services in any way other than through the currently available, published interfaces that we provide. For example, this means that you cannot scrape the Services without X’s express written permission, try to work around any technical limitations we impose, or otherwise attempt to disrupt the operation of the Services. We have broad enforcement rights: X reserves the right to take enforcement actions against you if you do violate these terms, such as, for example, removing your Content, limiting visibility, discontinuing your access to X, or taking legal action. Certain jurisdictions, including the European Union and the United Kingdom, also impose obligations on X to enforce against not only illegal content but also categories of content deemed by law to be “harmful” or “unsafe.” As a result, your Content or account may be subject to restrictions in those jurisdictions. We may also suspend or terminate your account for other reasons, such as prolonged inactivity, risk of legal exposure, or commercial inviability. There are intellectual property licenses in these Terms: You retain ownership and rights to any of your Content you post or share, and you provide us with a broad, royalty-free license to make your Content available to the rest of the world and to let others do the same. Conversely, we provide you a license to use the software we provide as part of the Services, such as the X mobile application, solely for the purpose of enabling you to use and enjoy the benefit of the Services. Your use of the Services is at your own risk: We provide the Services on an “AS IS” and “AS AVAILABLE” basis, and we disclaim all warranties, responsibility, and liability to you or others to the extent permitted by law. You may be exposed to offensive or harmful Content posted by other users. The Services may change from time to time, and we may limit or terminate availability of the Services or particular features to you or other users at any time. You have remedies and redress mechanisms, but our liability is limited: You have a right to terminate this agreement at any time by deactivating your account and discontinuing use of the Services. Depending on your country of residence, we may not be liable for certain types of damages as described in the agreement, and in any event, our aggregate liability shall not exceed the greater of $100 USD or the amount you paid us, if any, in the past six months for the Services giving rise to the claim. Further, if you believe that your Content has been displayed on the Services in an unauthorized manner that constitutes copyright infringement, the reporting process is detailed in these Terms. If you are a recipient of the X Service in the United Kingdom, you may challenge enforcement actions (such as Content removal or account suspension) that breach these Terms by filing a complaint through our internal complaints process or by bringing a claim in a competent court, as provided under the Online Safety Act 2023. You can find details on how to file a complaint here . If you are a recipient of the X Service in the European Union, you may challenge certain decisions we make under the Digital Services Act (Regulation (EU) 2022/2065) via our internal process or via out-of-court dispute settlement as described here . Please also note that these Terms incorporate our Privacy Policy ( https://x.com/privacy ) as well as other terms applicable to your use of the Services and your Content. Finally, these Terms may vary depending on where you live, but in any case, you must be at least 13 years old to use X. If you live outside the European Union, EFTA States, or the United Kingdom, including if you live in the United States, the X User Agreement comprises these Terms of Service , our Privacy Policy , our Rules and Policies , and all incorporated policies. If you live in the European Union, EFTA States, or the United Kingdom, the X User Agreement comprises these Terms of Service , our Privacy Policy , our Rules and Policies , and all incorporated policies.

By using or paying for any of these additional services, you agree to any additional terms applicable to those services, and those additional terms become part of our agreement with you. If any of the applicable additional terms conflict with these Terms, the additional terms will prevail while you are using those services to which they apply.

We cannot and will not be liable for any loss or damage arising from your failure to comply with the above. You can control most communications from the Services. We may need to provide you with certain communications, such as service announcements and administrative messages. These communications are considered part of the Services and your account, and you may not be able to opt-out from receiving them. If you added your phone number to your account and you later change or deactivate that phone number, you must update your account information to help prevent us from communicating with anyone who acquires your old number. Your License to Use the Services We give you a personal, worldwide, royalty-free, non-assignable and non-exclusive license to use the software provided to you as part of the Services. This license cannot be assigned, gifted, sold, shared or transferred in any other manner to any other individual or entity without X’s express written consent. This license has the sole purpose of enabling you to use and enjoy the benefit of the Services as provided on X, in the manner permitted by these Terms. The Services are protected by copyright, trademark, and other laws of both the United States and other countries. Nothing in the Terms gives you a right to use the X name or Twitter name or any of the X or Twitter trademarks, logos, domain names, other distinctive brand features, and other proprietary rights, and you may not do so without our express written consent. All right, title, and interest in and to the Services (excluding Content provided by users) are and will remain our and our licensors' exclusive property. Any feedback, comments, or suggestions you may provide regarding X, or the Services is entirely voluntary and we will be free to use such feedback, comments or suggestions as we see fit and without any obligation to you. Misuse of the Services You also agree not to misuse the Services, for example, by interfering with them or accessing them using a method other than the interface and the instructions that we provide. You agree that you will not work around any technical limitations in the software provided to you as part of the Services, or reverse engineer, decompile or disassemble the software, except and only to the extent that applicable law expressly permits.

It is also a violation of these Terms to facilitate or assist others in violating these Terms, including by distributing products or services that enable or encourage violation of these Terms. Ending These Terms You may end your legal agreement with us at any time by deactivating your accounts and discontinuing your use of the Services. See https://help.x.com/managing-your-account/how-to-deactivate-x-account for instructions on how to deactivate your account and the Privacy Policy for more information on what happens to your information. We may suspend or terminate your account or cease providing you with all or part of the Services at any time if we reasonably believe: (i) you have violated these Terms or our Rules and Policies , (ii) you create risk or possible legal exposure for us; (iii) your account should be removed due to unlawful conduct; (iv) your account should be removed due to prolonged inactivity; or (v) our provision of the Services to you is no longer commercially viable. We will make reasonable efforts to notify you by the email address associated with your account or the next time you attempt to access your account, depending on the circumstances. To the extent permitted by law, we may also terminate your account or cease providing you with all or part of the Services for any other reason or no reason at our convenience. In all such cases, the Terms shall terminate, including, without limitation, your license to use the Services, except that the following sections shall continue to apply: 2, 3, 5, 6, and the misuse provisions of Section 4 (“Misuse of the Services”). If you believe your account was terminated in error you can file an appeal following the steps found in our Help Center ( https://help.x.com/forms/account-access/appeals ).

Kuchling This article explains the new features in Python 2.4.1, released on March 30, 2005. Python 2.4 is a medium-sized release. It doesn’t introduce as many changes as the radical Python 2.2, but introduces more features than the conservative 2.3 release. The most significant new language features are function decorators and generator expressions; most other changes are to the standard library. According to the CVS change logs, there were 481 patches applied and 502 bugs fixed between Python 2.3 and 2.4. Both figures are likely to be underestimates. This article doesn’t attempt to provide a complete specification of every single new feature, but instead provides a brief introduction to each feature. For full details, you should refer to the documentation for Python 2.4, such as the Python Library Reference and the Python Reference Manual. Often you will be referred to the PEP for a particular new feature for explanations of the implementation and design rationale. PEP 218: Built-In Set Objects ¶ Python 2.3 introduced the sets module. C implementations of set data types have now been added to the Python core as two new built-in types, set(iterable) and frozenset(iterable) . They provide high speed operations for membership testing, for eliminating duplicates from sequences, and for mathematical operations like unions, intersections, differences, and symmetric differences. >>> a = set ( 'abracadabra' ) # form a set from a string >>> 'z' in a # fast membership testing False >>> a # unique letters in a set(['a', 'r', 'b', 'c', 'd']) >>> '' . join ( a ) # convert back into a string 'arbcd' >>> b = set ( 'alacazam' ) # form a second set >>> a - b # letters in a but not in b set(['r', 'd', 'b']) >>> a | b # letters in either a or b set(['a', 'c', 'r', 'd', 'b', 'm', 'z', 'l']) >>> a & b # letters in both a and b set(['a', 'c']) >>> a ^ b # letters in a or b but not both set(['r', 'd', 'b', 'm', 'z', 'l']) >>> a . add ( 'z' ) # add a new element >>> a . update ( 'wxy' ) # add multiple new elements >>> a set(['a', 'c', 'b', 'd', 'r', 'w', 'y', 'x', 'z']) >>> a . remove ( 'x' ) # take one element out >>> a set(['a', 'c', 'b', 'd', 'r', 'w', 'y', 'z']) The frozenset() type is an immutable version of set() . Since it is immutable and hashable, it may be used as a dictionary key or as a member of another set. The sets module remains in the standard library, and may be useful if you wish to subclass the Set or ImmutableSet classes. There are currently no plans to deprecate the module. See also PEP 218 - Adding a Built-In Set Object Type Originally proposed by Greg Wilson and ultimately implemented by Raymond Hettinger. PEP 237: Unifying Long Integers and Integers ¶ The lengthy transition process for this PEP, begun in Python 2.2, takes another step forward in Python 2.4. In 2.3, certain integer operations that would behave differently after int/long unification triggered FutureWarning warnings and returned values limited to 32 or 64 bits (depending on your platform). In 2.4, these expressions no longer produce a warning and instead produce a different result that’s usually a long integer. The problematic expressions are primarily left shifts and lengthy hexadecimal and octal constants. For example, 2 << 32 results in a warning in 2.3, evaluating to 0 on 32-bit platforms. In Python 2.4, this expression now returns the correct answer, 8589934592. See also PEP 237 - Unifying Long Integers and Integers Original PEP written by Moshe Zadka and GvR. The changes for 2.4 were implemented by Kalle Svensson. PEP 289: Generator Expressions ¶ The iterator feature introduced in Python 2.2 and the itertools module make it easier to write programs that loop through large data sets without having the entire data set in memory at one time. List comprehensions don’t fit into this picture very well because they produce a Python list object containing all of the items. This unavoidably pulls all of the objects into memory, which can be a problem if your data set is very large. When trying to write a functionally styled program, it would be natural to write something like: links = [ link for link in get_all_links () if not link . followed ] for link in links : ... instead of for link in get_all_links (): if link . followed : continue ... The first form is more concise and perhaps more readable, but if you’re dealing with a large number of link objects you’d have to write the second form to avoid having all link objects in memory at the same time. Generator expressions work similarly to list comprehensions but don’t materialize the entire list; instead they create a generator that will return elements one by one. The above example could be written as: links = ( link for link in get_all_links () if not link . followed ) for link in links : ... Generator expressions always have to be written inside parentheses, as in the above example. The parentheses signalling a function call also count, so if you want to create an iterator that will be immediately passed to a function you could write: print sum ( obj . count for obj in list_all_objects ()) Generator expressions differ from list comprehensions in various small ways. Most notably, the loop variable ( obj in the above example) is not accessible outside of the generator expression. List comprehensions leave the variable assigned to its last value; future versions of Python will change this, making list comprehensions match generator expressions in this respect. See also PEP 289 - Generator Expressions Proposed by Raymond Hettinger and implemented by Jiwon Seo with early efforts steered by Hye-Shik Chang. PEP 292: Simpler String Substitutions ¶ Some new classes in the standard library provide an alternative mechanism for substituting variables into strings; this style of substitution may be better for applications where untrained users need to edit templates. The usual way of substituting variables by name is the % operator: >>> ' %(page)i : %(title)s ' % { 'page' : 2 , 'title' : 'The Best of Times' } '2: The Best of Times' When writing the template string, it can be easy to forget the i or s after the closing parenthesis. This isn’t a big problem if the template is in a Python module, because you run the code, get an “Unsupported format character” ValueError , and fix the problem. However, consider an application such as Mailman where template strings or translations are being edited by users who aren’t aware of the Python language. The format string’s syntax is complicated to explain to such users, and if they make a mistake, it’s difficult to provide helpful feedback to them. PEP 292 adds a Template class to the string module that uses $ to indicate a substitution: >>> import string >>> t = string . Template ( '$page: $title' ) >>> t . substitute ({ 'page' : 2 , 'title' : 'The Best of Times' }) '2: The Best of Times' If a key is missing from the dictionary, the substitute() method will raise a KeyError . There’s also a safe_substitute() method that ignores missing keys: >>> t = string . Template ( '$page: $title' ) >>> t . safe_substitute ({ 'page' : 3 }) '3: $title' See also PEP 292 - Simpler String Substitutions Written and implemented by Barry Warsaw. PEP 318: Decorators for Functions and Methods ¶ Python 2.2 extended Python’s object model by adding static methods and class methods, but it didn’t extend Python’s syntax to provide any new way of defining static or class methods. Instead, you had to write a def statement in the usual way, and pass the resulting method to a staticmethod() or classmethod() function that would wrap up the function as a method of the new type. Your code would look like this: class C : def meth ( cls ): ... meth = classmethod ( meth ) # Rebind name to wrapped-up class method If the method was very long, it would be easy to miss or forget the classmethod() invocation after the function body. The intention was always to add some syntax to make such definitions more readable, but at the time of 2.2’s release a good syntax was not obvious. Today a good syntax still isn’t obvious but users are asking for easier access to the feature; a new syntactic feature has been added to meet this need. The new feature is called “function decorators”. The name comes from the idea that classmethod() , staticmethod() , and friends are storing additional information on a function object; they’re decorating functions with more details. The notation borrows from Java and uses the '@' character as an indicator. Using the new syntax, the example above would be written: class C : @classmethod def meth ( cls ): ... The @classmethod is shorthand for the meth=classmethod(meth) assignment. More generally, if you have the following: @A @B @C def f (): ... It’s equivalent to the following pre-decorator code: def f (): ... f = A ( B ( C ( f ))) Decorators must come on the line before a function definition, one decorator per line, and can’t be on the same line as the def statement, meaning that @A def f(): ... is illegal. You can only decorate function definitions, either at the module level or inside a class; you can’t decorate class definitions. A decorator is just a function that takes the function to be decorated as an argument and returns either the same function or some new object. The return value of the decorator need not be callable (though it typically is), unless further decorators will be applied to the result. It’s easy to write your own decorators. The following simple example just sets an attribute on the function object: >>> def deco ( func ): ... func . attr = 'decorated' ... return func ... >>> @deco ... def f (): pass ... >>> f <function f at 0x402ef0d4> >>> f . attr 'decorated' >>> As a slightly more realistic example, the following decorator checks that the supplied argument is an integer: def require_int ( func ): def wrapper ( arg ): assert isinstance ( arg , int ) return func ( arg ) return wrapper @require_int def p1 ( arg ): print arg @require_int def p2 ( arg ): print arg * 2 An example in PEP 318 contains a fancier version of this idea that lets you both specify the required type and check the returned type. Decorator functions can take arguments. If arguments are supplied, your decorator function is called with only those arguments and must return a new decorator function; this function must take a single function and return a function, as previously described. In other words, @A @B @C(args) becomes: def f (): ... _deco = C ( args ) f = A ( B ( _deco ( f ))) Getting this right can be slightly brain-bending, but it’s not too difficult. A small related change makes the func_name attribute of functions writable. This attribute is used to display function names in tracebacks, so decorators should change the name of any new function that’s constructed and returned. See also PEP 318 - Decorators for Functions, Methods and Classes Written by Kevin D. Smith, Jim Jewett, and Skip Montanaro. Several people wrote patches implementing function decorators, but the one that was actually checked in was patch #979728, written by Mark Russell. https://wiki.python.org/moin/PythonDecoratorLibrary This Wiki page contains several examples of decorators. PEP 322: Reverse Iteration ¶ A new built-in function, reversed(seq) , takes a sequence and returns an iterator that loops over the elements of the sequence in reverse order. >>> for i in reversed ( xrange ( 1 , 4 )): ... print i ... 3 2 1 Compared to extended slicing, such as range(1,4)[::-1] , reversed() is easier to read, runs faster, and uses substantially less memory. Note that reversed() only accepts sequences, not arbitrary iterators. If you want to reverse an iterator, first convert it to a list with list() . >>> input = open ( '/etc/passwd' , 'r' ) >>> for line in reversed ( list ( input )): ... print line ... root:*:0:0:System Administrator:/var/root:/bin/tcsh ... See also PEP 322 - Reverse Iteration Written and implemented by Raymond Hettinger. PEP 324: New subprocess Module ¶ The standard library provides a number of ways to execute a subprocess, offering different features and different levels of complexity. os.system(command) is easy to use, but slow (it runs a shell process which executes the command) and dangerous (you have to be careful about escaping the shell’s metacharacters). The popen2 module offers classes that can capture standard output and standard error from the subprocess, but the naming is confusing. The subprocess module cleans this up, providing a unified interface that offers all the features you might need. Instead of popen2 ’s collection of classes, subprocess contains a single class called subprocess.Popen whose constructor supports a number of different keyword arguments. class Popen ( args , bufsize = 0 , executable = None , stdin = None , stdout = None , stderr = None , preexec_fn = None , close_fds = False , shell = False , cwd = None , env = None , universal_newlines = False , startupinfo = None , creationflags = 0 ): args is commonly a sequence of strings that will be the arguments to the program executed as the subprocess. (If the shell argument is true, args can be a string which will then be passed on to the shell for interpretation, just as os.system() does.) stdin , stdout , and stderr specify what the subprocess’s input, output, and error streams will be. You can provide a file object or a file descriptor, or you can use the constant subprocess.PIPE to create a pipe between the subprocess and the parent. The constructor has a number of handy options: close_fds requests that all file descriptors be closed before running the subprocess. cwd specifies the working directory in which the subprocess will be executed (defaulting to whatever the parent’s working directory is). env is a dictionary specifying environment variables. preexec_fn is a function that gets called before the child is started. universal_newlines opens the child’s input and output using Python’s universal newlines feature. Once you’ve created the Popen instance, you can call its wait() method to pause until the subprocess has exited, poll() to check if it’s exited without pausing, or communicate(data) to send the string data to the subprocess’s standard input. communicate(data) then reads any data that the subprocess has sent to its standard output or standard error, returning a tuple (stdout_data, stderr_data) . call() is a shortcut that passes its arguments along to the Popen constructor, waits for the command to complete, and returns the status code of the subprocess. It can serve as a safer analog to os.system() : sts = subprocess . call ([ 'dpkg' , '-i' , '/tmp/new-package.deb' ]) if sts == 0 : # Success ... else : # dpkg returned an error ... The command is invoked without use of the shell. If you really do want to use the shell, you can add shell=True as a keyword argument and provide a string instead of a sequence: sts = subprocess . call ( 'dpkg -i /tmp/new-package.deb' , shell = True ) The PEP takes various examples of shell and Python code and shows how they’d be translated into Python code that uses subprocess . Reading this section of the PEP is highly recommended. See also PEP 324 - subprocess - New process module Written and implemented by Peter Åstrand, with assistance from Fredrik Lundh and others. PEP 327: Decimal Data Type ¶ Python has always supported floating-point (FP) numbers, based on the underlying C double type, as a data type. However, while most programming languages provide a floating-point type, many people (even programmers) are unaware that floating-point numbers don’t represent certain decimal fractions accurately. The new Decimal type can represent these fractions accurately, up to a user-specified precision limit. Why is Decimal needed? ¶ The limitations arise from the representation used for floating-point numbers. FP numbers are made up of three components: The sign, which is positive or negative. The mantissa, which is a single-digit binary number followed by a fractional part. For example, 1.01 in base-2 notation is 1 + 0/2 + 1/4 , or 1.25 in decimal notation. The exponent, which tells where the decimal point is located in the number represented. For example, the number 1.25 has positive sign, a mantissa value of 1.01 (in binary), and an exponent of 0 (the decimal point doesn’t need to be shifted). The number 5 has the same sign and mantissa, but the exponent is 2 because the mantissa is multiplied by 4 (2 to the power of the exponent 2); 1.25 * 4 equals 5. Modern systems usually provide floating-point support that conforms to a standard called IEEE 754. C’s double type is usually implemented as a 64-bit IEEE 754 number, which uses 52 bits of space for the mantissa. This means that numbers can only be specified to 52 bits of precision. If you’re trying to represent numbers whose expansion repeats endlessly, the expansion is cut off after 52 bits. Unfortunately, most software needs to produce output in base 10, and common fractions in base 10 are often repeating decimals in binary. For example, 1.1 decimal is binary 1.0001100110011 ... ; .1 = 1/16 + 1/32 + 1/256 plus an infinite number of additional terms. IEEE 754 has to chop off that infinitely repeated decimal after 52 digits, so the representation is slightly inaccurate. Sometimes you can see this inaccuracy when the number is printed: >>> 1.1 1.1000000000000001 The inaccuracy isn’t always visible when you print the number because the FP-to-decimal-string conversion is provided by the C library, and most C libraries try to produce sensible output. Even if it’s not displayed, however, the inaccuracy is still there and subsequent operations can magnify the error. For many applications this doesn’t matter. If I’m plotting points and displaying them on my monitor, the difference between 1.1 and 1.1000000000000001 is too small to be visible. Reports often limit output to a certain number of decimal places, and if you round the number to two or three or even eight decimal places, the error is never apparent. However, for applications where it does matter, it’s a lot of work to implement your own custom arithmetic routines. Hence, the Decimal type was created. The Decimal type ¶ A new module, decimal , was added to Python’s standard library. It contains two classes, Decimal and Context . Decimal instances represent numbers, and Context instances are used to wrap up various settings such as the precision and default rounding mode. Decimal instances are immutable, like regular Python integers and FP numbers; once it’s been created, you can’t change the value an instance represents. Decimal instances can be created from integers or strings: >>> import decimal >>> decimal . Decimal ( 1972 ) Decimal("1972") >>> decimal . Decimal ( "1.1" ) Decimal("1.1") You can also provide tuples containing the sign, the mantissa represented as a tuple of decimal digits, and the exponent: >>> decimal . Decimal (( 1 , ( 1 , 4 , 7 , 5 ), - 2 )) Decimal("-14.75") Cautionary note: the sign bit is a Boolean value, so 0 is positive and 1 is negative. Converting from floating-point numbers poses a bit of a problem: should the FP number representing 1.1 turn into the decimal number for exactly 1.1, or for 1.1 plus whatever inaccuracies are introduced? The decision was to dodge the issue and leave such a conversion out of the API. Instead, you should convert the floating-point number into a string using the desired precision and pass the string to the Decimal constructor: >>> f = 1.1 >>> decimal . Decimal ( str ( f )) Decimal("1.1") >>> decimal . Decimal ( ' %.12f ' % f ) Decimal("1.100000000000") Once you have Decimal instances, you can perform the usual mathematical operations on them. One limitation: exponentiation requires an integer exponent: >>> a = decimal . Decimal ( '35.72' ) >>> b = decimal . Decimal ( '1.73' ) >>> a + b Decimal("37.45") >>> a - b Decimal("33.99") >>> a * b Decimal("61.7956") >>> a / b Decimal("20.64739884393063583815028902") >>> a ** 2 Decimal("1275.9184") >>> a ** b Traceback (most recent call last): ... decimal.InvalidOperation : x ** (non-integer) You can combine Decimal instances with integers, but not with floating-point numbers: >>> a + 4 Decimal("39.72") >>> a + 4.5 Traceback (most recent call last): ... TypeError : You can interact Decimal only with int, long or Decimal data types. >>> Decimal numbers can be used with the math and cmath modules, but note that they’ll be immediately converted to floating-point numbers before the operation is performed, resulting in a possible loss of precision and accuracy. You’ll also get back a regular floating-point number and not a Decimal . >>> import math , cmath >>> d = decimal . Decimal ( '123456789012.345' ) >>> math . sqrt ( d ) 351364.18288201344 >>> cmath . sqrt ( - d ) 351364.18288201344j Decimal instances have a sqrt() method that returns a Decimal , but if you need other things such as trigonometric functions you’ll have to implement them. >>> d . sqrt () Decimal("351364.1828820134592177245001") The Context type ¶ Instances of the Context class encapsulate several settings for decimal operations: prec is the precision, the number of decimal places. rounding specifies the rounding mode. The decimal module has constants for the various possibilities: ROUND_DOWN , ROUND_CEILING , ROUND_HALF_EVEN , and various others. traps is a dictionary specifying what happens on encountering certain error conditions: either an exception is raised or a value is returned. Some examples of error conditions are division by zero, loss of precision, and overflow. There’s a thread-local default context available by calling getcontext() ; you can change the properties of this context to alter the default precision, rounding, or trap handling. The following example shows the effect of changing the precision of the default context: >>> decimal . getcontext () . prec 28 >>> decimal . Decimal ( 1 ) / decimal . Decimal ( 7 ) Decimal("0.1428571428571428571428571429") >>> decimal . getcontext () . prec = 9 >>> decimal . Decimal ( 1 ) / decimal . Decimal ( 7 ) Decimal("0.142857143") The default action for error conditions is selectable; the module can either return a special value such as infinity or not-a-number, or exceptions can be raised: >>> decimal . Decimal ( 1 ) / decimal . Decimal ( 0 ) Traceback (most recent call last): ... decimal.DivisionByZero : x / 0 >>> decimal . getcontext () . traps [ decimal . DivisionByZero ] = False >>> decimal . Decimal ( 1 ) / decimal . Decimal ( 0 ) Decimal("Infinity") >>> The Context instance also has various methods for formatting numbers such as to_eng_string() and to_sci_string() . For more information, see the documentation for the decimal module, which includes a quick-start tutorial and a reference. See also PEP 327 - Decimal Data Type Written by Facundo Batista and implemented by Facundo Batista, Eric Price, Raymond Hettinger, Aahz, and Tim Peters. http://www.lahey.com/float.htm The article uses Fortran code to illustrate many of the problems that floating-point inaccuracy can cause. https://speleotrove.com/decimal/ A description of a decimal-based representation. This representation is being proposed as a standard, and underlies the new Python decimal type. Much of this material was written by Mike Cowlishaw, designer of the Rexx language. PEP 328: Multi-line Imports ¶ One language change is a small syntactic tweak aimed at making it easier to import many names from a module. In a from module import names statement, names is a sequence of names separated by commas. If the sequence is very long, you can either write multiple imports from the same module, or you can use backslashes to escape the line endings like this: from SimpleXMLRPCServer import SimpleXMLRPCServer , \ SimpleXMLRPCRequestHandler , \ CGIXMLRPCRequestHandler , \ resolve_dotted_attribute The syntactic change in Python 2.4 simply allows putting the names within parentheses. Python ignores newlines within a parenthesized expression, so the backslashes are no longer needed: from SimpleXMLRPCServer import ( SimpleXMLRPCServer , SimpleXMLRPCRequestHandler , CGIXMLRPCRequestHandler , resolve_dotted_attribute ) The PEP also proposes that all import statements be absolute imports, with a leading . character to indicate a relative import. This part of the PEP was not implemented for Python 2.4, but was completed for Python 2.5. See also PEP 328 - Imports: Multi-Line and Absolute/Relative Written by Aahz. Multi-line imports were implemented by Dima Dorfman. PEP 331: Locale-Independent Float/String Conversions ¶ The locale modules lets Python software select various conversions and display conventions that are localized to a particular country or language. However, the module was careful to not change the numeric locale because various functions in Python’s implementation required that the numeric locale remain set to the 'C' locale. Often this was because the code was using the C library’s atof() function. Not setting the numeric locale caused trouble for extensions that used third-party C libraries, however, because they wouldn’t have the correct locale set. The motivating example was GTK+, whose user interface widgets weren’t displaying numbers in the current locale. The solution described in the PEP is to add three new functions to the Python API that perform ASCII-only conversions, ignoring the locale setting: PyOS_ascii_strtod(str, ptr) and PyOS_ascii_atof(str, ptr) both convert a string to a C double . PyOS_ascii_formatd(buffer, buf_len, format, d) converts a double to an ASCII string. The code for these functions came from the GLib library ( https://developer-old.gnome.org/glib/2.26/ ), whose developers kindly relicensed the relevant functions and donated them to the Python Software Foundation. The locale module can now change the numeric locale, letting extensions such as GTK+ produce the correct results. See also PEP 331 - Locale-Independent Float/String Conversions Written by Christian R. Reis, and implemented by Gustavo Carneiro. Other Language Changes ¶ Here are all of the changes that Python 2.4 makes to the core Python language. Decorators for functions and methods were added ( PEP 318 ). Built-in set() and frozenset() types were added ( PEP 218 ). Other new built-ins include the reversed(seq) function ( PEP 322 ). Generator expressions were added ( PEP 289 ). Certain numeric expressions no longer return values restricted to 32 or 64 bits ( PEP 237 ). You can now put parentheses around the list of names in a from module import names statement ( PEP 328 ). The dict.update() method now accepts the same argument forms as the dict constructor. This includes any mapping, any iterable of key/value pairs, and keyword arguments. (Contributed by Raymond Hettinger.) The string methods ljust() , rjust() , and center() now take an optional argument for specifying a fill character other than a space. (Contributed by Raymond Hettinger.) Strings also gained an rsplit() method that works like the split() method but splits from the end of the string. (Contributed by Sean Reifschneider.) >>> 'www.python.org' . split ( '.' , 1 ) ['www', 'python.org'] 'www.python.org'.rsplit('.', 1) ['www.python', 'org'] Three keyword parameters, cmp , key , and reverse , were added to the sort() method of lists. These parameters make some common usages of sort() simpler. All of these parameters are optional. For the cmp parameter, the value should be a comparison function that takes two parameters and returns -1, 0, or +1 depending on how the parameters compare. This function will then be used to sort the list. Previously this was the only parameter that could be provided to sort() . key should be a single-parameter function that takes a list element and returns a comparison key for the element. The list is then sorted using the comparison keys. The following example sorts a list case-insensitively: >>> L = [ 'A' , 'b' , 'c' , 'D' ] >>> L . sort () # Case-sensitive sort >>> L ['A', 'D', 'b', 'c'] >>> # Using 'key' parameter to sort list >>> L . sort ( key = lambda x : x . lower ()) >>> L ['A', 'b', 'c', 'D'] >>> # Old-fashioned way >>> L . sort ( cmp = lambda x , y : cmp ( x . lower (), y . lower ())) >>> L ['A', 'b', 'c', 'D'] The last example, which uses the cmp parameter, is the old way to perform a case-insensitive sort. It works but is slower than using a key parameter. Using key calls lower() method once for each element in the list while using cmp will call it twice for each comparison, so using key saves on invocations of the lower() method. For simple key functions and comparison functions, it is often possible to avoid a lambda expression by using an unbound method instead. For example, the above case-insensitive sort is best written as: >>> L . sort ( key = str . lower ) >>> L ['A', 'b', 'c', 'D'] Finally, the reverse parameter takes a Boolean value. If the value is true, the list will be sorted into reverse order. Instead of L.sort(); L.reverse() , you can now write L.sort(reverse=True) . The results of sorting are now guaranteed to be stable. This means that two entries with equal keys will be returned in the same order as they were input. For example, you can sort a list of people by name, and then sort the list by age, resulting in a list sorted by age where people with the same age are in name-sorted order. (All changes to sort() contributed by Raymond Hettinger.) There is a new built-in function sorted(iterable) that works like the in-place list.sort() method but can be used in expressions. The differences are: the input may be any iterable; a newly formed copy is sorted, leaving the original intact; and the expression returns the new sorted copy >>> L = [ 9 , 7 , 8 , 3 , 2 , 4 , 1 , 6 , 5 ] >>> [ 10 + i for i in sorted ( L )] # usable in a list comprehension [11, 12, 13, 14, 15, 16, 17, 18, 19] >>> L # original is left unchanged [9,7,8,3,2,4,1,6,5] >>> sorted ( 'Monty Python' ) # any iterable may be an input [' ', 'M', 'P', 'h', 'n', 'n', 'o', 'o', 't', 't', 'y', 'y'] >>> # List the contents of a dict sorted by key values >>> colormap = dict ( red = 1 , blue = 2 , green = 3 , black = 4 , yellow = 5 ) >>> for k , v in sorted ( colormap . iteritems ()): ... print k , v ... black 4 blue 2 green 3 red 1 yellow 5 (Contributed by Raymond Hettinger.) Integer operations will no longer trigger an OverflowWarning . The OverflowWarning warning will disappear in Python 2.5. The interpreter gained a new switch, -m , that takes a name, searches for the corresponding module on sys.path , and runs the module as a script. For example, you can now run the Python profiler with python -m profile . (Contributed by Nick Coghlan.) The eval(expr, globals, locals) and execfile(filename, globals, locals) functions and the exec statement now accept any mapping type for the locals parameter. Previously this had to be a regular Python dictionary. (Contributed by Raymond Hettinger.) The zip() built-in function and itertools.izip() now return an empty list if called with no arguments. Previously they raised a TypeError exception. This makes them more suitable for use with variable length argument lists: >>> def transpose ( array ): ... return zip ( * array ) ... >>> transpose ([( 1 , 2 , 3 ), ( 4 , 5 , 6 )]) [(1, 4), (2, 5), (3, 6)] >>> transpose ([]) [] (Contributed by Raymond Hettinger.) Encountering a failure while importing a module no longer leaves a partially initialized module object in sys.modules . The incomplete module object left behind would fool further imports of the same module into succeeding, leading to confusing errors. (Fixed by Tim Peters.) None is now a constant; code that binds a new value to the name None is now a syntax error. (Contributed by Raymond Hettinger.) Optimizations ¶ The inner loops for list and tuple slicing were optimized and now run about one-third faster. The inner loops for dictionaries were also optimized, resulting in performance boosts for keys() , values() , items() , iterkeys() , itervalues() , and iteritems() . (Contributed by Raymond Hettinger.) The machinery for growing and shrinking lists was optimized for speed and for space efficiency. Appending and popping from lists now runs faster due to more efficient code paths and less frequent use of the underlying system realloc() . List comprehensions also benefit. list.extend() was also optimized and no longer converts its argument into a temporary list before extending the base list. (Contributed by Raymond Hettinger.) list() , tuple() , map() , filter() , and zip() now run several times faster with non-sequence arguments that supply a __len__() method. (Contributed by Raymond Hettinger.) The methods list.__getitem__() , dict.__getitem__() , and dict.__contains__() are now implemented as method_descriptor objects rather than wrapper_descriptor objects. This form of access doubles their performance and makes them more suitable for use as arguments to functionals: map(mydict.__getitem__, keylist) . (Contributed by Raymond Hettinger.) Added a new opcode, LIST_APPEND , that simplifies the generated bytecode for list comprehensions and speeds them up by about a third. (Contributed by Raymond Hettinger.) The peephole bytecode optimizer has been improved to produce shorter, faster bytecode; remarkably, the resulting bytecode is more readable. (Enhanced by Raymond Hettinger.) String concatenations in statements of the form s = s + "abc" and s += "abc" are now performed more efficiently in certain circumstances. This optimization won’t be present in other Python implementations such as Jython, so you shouldn’t rely on it; using the join() method of strings is still recommended when you want to efficiently glue a large number of strings together. (Contributed by Armin Rigo.) The net result of the 2.4 optimizations is that Python 2.4 runs the pystone benchmark around 5% faster than Python 2.3 and 35% faster than Python 2.2. (pystone is not a particularly good benchmark, but it’s the most commonly used measurement of Python’s performance. Your own applications may show greater or smaller benefits from Python 2.4.) New, Improved, and Deprecated Modules ¶ As usual, Python’s standard library received a number of enhancements and bug fixes. Here’s a partial list of the most notable changes, sorted alphabetically by module name. Consult the Misc/NEWS file in the source tree for a more complete list of changes, or look through the CVS logs for all the details. The asyncore module’s loop() function now has a count parameter that lets you perform a limited number of passes through the polling loop. The default is still to loop forever. The base64 module now has more complete RFC 3548 support for Base64, Base32, and Base16 encoding and decoding, including optional case folding and optional alternative alphabets. (Contributed by Barry Warsaw.) The bisect module now has an underlying C implementation for improved performance. (Contributed by Dmitry Vasiliev.) The CJKCodecs collections of East Asian codecs, maintained by Hye-Shik Chang, was integrated into 2.4. The new encodings are: Chinese (PRC): gb2312, gbk, gb18030, big5hkscs, hz Chinese (ROC): big5, cp950 Japanese: cp932, euc-jis-2004, euc-jp, euc-jisx0213, iso-2022-jp, iso-2022-jp-1, iso-2022-jp-2, iso-2022-jp-3, iso-2022-jp-ext, iso-2022-jp-2004, shift-jis, shift-jisx0213, shift-jis-2004 Korean: cp949, euc-kr, johab, iso-2022-kr Some other new encodings were added: HP Roman8, ISO_8859-11, ISO_8859-16, PCTP-154, and TIS-620. The UTF-8 and UTF-16 codecs now cope better with receiving partial input. Previously the StreamReader class would try to read more data, making it impossible to resume decoding from the stream. The read() method will now return as much data as it can and future calls will resume decoding where previous ones left off. (Implemented by Walter Dörwald.) There is a new collections module for various specialized collection datatypes. Currently it contains just one type, deque , a double-ended queue that supports efficiently adding and removing elements from either end: >>> from collections import deque >>> d = deque ( 'ghi' ) # make a new deque with three items >>> d . append ( 'j' ) # add a new entry to the right side >>> d . appendleft ( 'f' ) # add a new entry to the left side >>> d # show the representation of the deque deque(['f', 'g', 'h', 'i', 'j']) >>> d . pop () # return and remove the rightmost item 'j' >>> d . popleft () # return and remove the leftmost item 'f' >>> list ( d ) # list the contents of the deque ['g', 'h', 'i'] >>> 'h' in d # search the deque True Several modules, such as the Queue and threading modules, now take advantage of collections.deque for improved performance. (Contributed by Raymond Hettinger.) The ConfigParser classes have been enhanced slightly. The read() method now returns a list of the files that were successfully parsed, and the set() method raises TypeError if passed a value argument that isn’t a string. (Contributed by John Belmonte and David Goodger.) The curses module now supports the ncurses extension use_default_colors() . On platforms where the terminal supports transparency, this makes it possible to use a transparent background. (Contributed by Jörg Lehmann.) The difflib module now includes an HtmlDiff class that creates an HTML table showing a side by side comparison of two versions of a text. (Contributed by Dan Gass.) The email package was updated to version 3.0, which dropped various deprecated APIs and removes support for Python versions earlier than 2.3. The 3.0 version of the package uses a new incremental parser for MIME messages, available in the email.FeedParser module. The new parser doesn’t require reading the entire message into memory, and doesn’t raise exceptions if a message is malformed; instead it records any problems in the defect attribute of the message. (Developed by Anthony Baxter, Barry Warsaw, Thomas Wouters, and others.) The heapq module has been converted to C. The resulting tenfold improvement in speed makes the module suitable for handling high volumes of data. In addition, the module has two new functions nlargest() and nsmallest() that use heaps to find the N largest or smallest values in a dataset without the expense of a full sort. (Contributed by Raymond Hettinger.) The httplib module now contains constants for HTTP status codes defined in various HTTP-related RFC documents. Constants have names such as OK , CREATED , CONTINUE , and MOVED_PERMANENTLY ; use pydoc to get a full list. (Contributed by Andrew Eland.) The imaplib module now supports IMAP’s THREAD command (contributed by Yves Dionne) and new deleteacl() and myrights() methods (contributed by Arnaud Mazin). The itertools module gained a groupby(iterable[, *func*]) function. iterable is something that can be iterated over to return a stream of elements, and the optional func parameter is a function that takes an element and returns a key value; if omitted, the key is simply the element itself. groupby() then groups the elements into subsequences which have matching values of the key, and returns a series of 2-tuples containing the key value and an iterator over the subsequence. Here’s an example to make this clearer. The key function simply returns whether a number is even or odd, so the result of groupby() is to return consecutive runs of odd or even numbers. >>> import itertools >>> L = [ 2 , 4 , 6 , 7 , 8 , 9 , 11 , 12 , 14 ] >>> for key_val , it in itertools . groupby ( L , lambda x : x % 2 ): ... print key_val , list ( it ) ... 0 [2, 4, 6] 1 [7] 0 [8] 1 [9, 11] 0 [12, 14] >>> groupby() is typically used with sorted input. The logic for groupby() is similar to the Unix uniq filter which makes it handy for eliminating, counting, or identifying duplicate elements: >>> word = 'abracadabra' >>> letters = sorted ( word ) # Turn string into a sorted list of letters >>> letters ['a', 'a', 'a', 'a', 'a', 'b', 'b', 'c', 'd', 'r', 'r'] >>> for k , g in itertools . groupby ( letters ): ... print k , list ( g ) ... a ['a', 'a', 'a', 'a', 'a'] b ['b', 'b'] c ['c'] d ['d'] r ['r', 'r'] >>> # List unique letters >>> [ k for k , g in groupby ( letters )] ['a', 'b', 'c', 'd', 'r'] >>> # Count letter occurrences >>> [( k , len ( list ( g ))) for k , g in groupby ( letters )] [('a', 5), ('b', 2), ('c', 1), ('d', 1), ('r', 2)] (Contributed by Hye-Shik Chang.) itertools also gained a function named tee(iterator, N) that returns N independent iterators that replicate iterator . If N is omitted, the default is 2. >>> L = [ 1 , 2 , 3 ] >>> i1 , i2 = itertools . tee ( L ) >>> i1 , i2 (<itertools.tee object at 0x402c2080>, <itertools.tee object at 0x402c2090>) >>> list ( i1 ) # Run the first iterator to exhaustion [1, 2, 3] >>> list ( i2 ) # Run the second iterator to exhaustion [1, 2, 3] Note that tee() has to keep copies of the values returned by the iterator; in the worst case, it may need to keep all of them. This should therefore be used carefully if the leading iterator can run far ahead of the trailing iterator in a long stream of inputs. If the separation is large, then you might as well use list() instead. When the iterators track closely with one another, tee() is ideal. Possible applications include bookmarking, windowing, or lookahead iterators. (Contributed by Raymond Hettinger.) A number of functions were added to the locale module, such as bind_textdomain_codeset() to specify a particular encoding and a family of l*gettext() functions that return messages in the chosen encoding. (Contributed by Gustavo Niemeyer.) Some keyword arguments were added to the logging package’s basicConfig() function to simplify log configuration. The default behavior is to log messages to standard error, but various keyword arguments can be specified to log to a particular file, change the logging format, or set the logging level. For example: import logging logging . basicConfig ( filename = '/var/log/application.log' , level = 0 , # Log all messages format = '%(levelname):%(process):%(thread):%(message)' ) Other additions to the logging package include a log(level, msg) convenience method, as well as a TimedRotatingFileHandler class that rotates its log files at a timed interval. The module already had RotatingFileHandler , which rotated logs once the file exceeded a certain size. Both classes derive from a new BaseRotatingHandler class that can be used to implement other rotating handlers. (Changes implemented by Vinay Sajip.) The marshal module now shares interned strings on unpacking a data structure. This may shrink the size of certain pickle strings, but the primary effect is to make .pyc files significantly smaller. (Contributed by Martin von Löwis.) The nntplib module’s NNTP class gained description() and descriptions() methods to retrieve newsgroup descriptions for a single group or for a range of groups. (Contributed by Jürgen A. Erhard.) Two new functions were added to the operator module, attrgetter(attr) and itemgetter(index) . Both functions return callables that take a single argument and return the corresponding attribute or item; these callables make excellent data extractors when used with map() or sorted() . For example: >>> L = [( 'c' , 2 ), ( 'd' , 1 ), ( 'a' , 4 ), ( 'b' , 3 )] >>> map ( operator . itemgetter ( 0 ), L ) ['c', 'd', 'a', 'b'] >>> map ( operator . itemgetter ( 1 ), L ) [2, 1, 4, 3] >>> sorted ( L , key = operator . itemgetter ( 1 )) # Sort list by second tuple item [('d', 1), ('c', 2), ('b', 3), ('a', 4)] (Contributed by Raymond Hettinger.) The optparse module was updated in various ways. The module now passes its messages through gettext.gettext() , making it possible to internationalize Optik’s help and error messages. Help messages for options can now include the string '%default' , which will be replaced by the option’s default value. (Contributed by Greg Ward.) The long-term plan is to deprecate the rfc822 module in some future Python release in favor of the email package. To this end, the email.Utils.formatdate function has been changed to make it usable as a replacement for rfc822.formatdate() . You may want to write new e-mail processing code with this in mind. (Change implemented by Anthony Baxter.) A new urandom(n) function was added to the os module, returning a string containing n bytes of random data. This function provides access to platform-specific sources of randomness such as /dev/urandom on Linux or the Windows CryptoAPI. (Contributed by Trevor Perrin.) Another new function: os.path.lexists(path) returns true if the file specified by path exists, whether or not it’s a symbolic link. This differs from the existing os.path.exists(path) function, which returns false if path is a symlink that points to a destination that doesn’t exist. (Contributed by Beni Cherniavsky.) A new getsid() function was added to the posix module that underlies the os module. (Contributed by J. Raynor.) The poplib module now supports POP over SSL. (Contributed by Hector Urtubia.) The profile module can now profile C extension functions. (Contributed by Nick Bastin.) The random module has a new method called getrandbits(N) that returns a long integer N bits in length. The existing randrange() method now uses getrandbits() where appropriate, making generation of arbitrarily large random numbers more efficient. (Contributed by Raymond Hettinger.) The regular expression language accepted by the re module was extended with simple conditional expressions, written as (?(group)A|B) . group is either a numeric group ID or a group name defined with (?P<group>...) earlier in the expression. If the specified group matched, the regular expression pattern A will be tested against the string; if the group didn’t match, the pattern B will be used instead. (Contributed by Gustavo Niemeyer.) The re module is also no longer recursive, thanks to a massive amount of work by Gustavo Niemeyer. In a recursive regular expression engine, certain patterns result in a large amount of C stack space being consumed, and it was possible to overflow the stack. For example, if you matched a 30000-byte string of a cha | 2026-01-13T08:49:25 |

These are guidelines that will help you avoid common pitfalls. Table of Contents Part 1 - The Basics What is Version Control? Why Use Version Control?

Learn on: Desktop GUI | Command Line Version Control Best Practices Here are some best practices to consider in order to make the most of Version Control. Commit Related Changes A commit should be a wrapper for related changes. For example, fixing two different bugs should produce two separate commits. Small commits make it easier for other team members to understand the changes and roll them back if something went wrong. With tools like the staging area and the ability to stage only parts of a file, Git makes it easy to create very granular commits. Commit Often Committing often keeps your commits small and, again, helps you commit only related changes. Moreover, it allows you to share your code more frequently with others. That way it’s easier for everyone to integrate changes regularly and avoid having merge conflicts. Having few large commits and sharing them rarely, in contrast, makes it hard both to solve conflicts and to comprehend what happened. Don’t Commit Half-Done Work You should only commit code when it’s completed. This doesn’t mean you have to complete a whole, large feature before committing. Quite the contrary: split the feature’s implementation into logical chunks and remember to commit early and often. But don’t commit just to have something in the repository before leaving the office at the end of the day. If you’re tempted to commit just because you need a clean working copy (to check out a branch, pull in changes, etc.) consider using Git’s “Stash” feature instead. Test Before You Commit Resist the temptation to commit something that you “think” is completed. Test it thoroughly to make sure it really is completed and has no side effects (as far as one can tell). While committing half-baked things in your local repository only requires you to forgive yourself, having your code tested is even more important when it comes to pushing / sharing your code with others. Write Good Commit Messages Begin your message with a short summary of your changes (up to 50 characters as a guideline). Separate it from the following body by including a blank line. The body of your message should provide detailed answers to the following questions: What was the motivation for the change? How does it differ from the previous implementation? Use the imperative, present tense („change“, not „changed“ or „changes“) to be consistent with generated messages from commands like git merge. Version Control is not a Backup System Having your files backed up on a remote server is a nice side effect of having a version control system. But you should not use your VCS like it was a backup system. When doing version control, you should pay attention to committing semantically (see “related changes”) – you shouldn’t just cram in files. Use Branches Branching is one of Git’s most powerful features – and this is not by accident: quick and easy branching was a central requirement from day one. Branches are the perfect tool to help you avoid mixing up different lines of development. You should use branches extensively in your development workflows: for new features, bug fixes, experiments, ideas… Agree on a Workflow Git lets you pick from a lot of different workflows: long-running branches, topic branches, merge or rebase, git-flow… Which one you choose depends on a couple of factors: your project, your overall development and deployment workflows and (maybe most importantly) on your and your teammates’ personal preferences. However you choose to work, just make sure to agree on a common workflow that everyone follows. More Learning Resources Contents Git for Subversion Users Get our popular Git Cheat Sheet for free!

(" 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 .

OpenAI Open in ChatGPT End of Support for @suprsend/web-inbox . Migrate to @suprsend/web-components We have upgraded authentication of inbox from HMAC to JWT as it is more secure. Please migrate to newer SDK if you are on old one. There are 2 ways in which you can implement inbox functionality: Drop-in components: Pre-built UI with many customizable options which require minimal effort to build. Headless implementation: For more advanced use cases where you want to build UI/UX from scratch. This guide help you integrate drop-in components in your non-react frameworks (angular, vuejs, vanillajs etc). If you want to build your own UI (headless) instead of using drop-in components please refer docs .

In this article, we'll explore how to monitor a notification service using Angular and Prometheus. Architecture Overview Our monitoring system will consist of the following components: Notification Service : The backend service responsible for sending notifications. Angular Frontend : The user interface built with Angular to display monitoring data. Prometheus : A monitoring system that collects and stores metrics from the notification service. Setting Up the Environment Install Angular : Set up an Angular project using the Angular CLI or your preferred method. Install Prometheus : Install Prometheus on your system and configure it to collect metrics from the notification service. Implementing Monitoring with Angular and Prometheus Create a Prometheus Dashboard : Create a Prometheus dashboard to display monitoring data using the Angular frontend. Collect Metrics : Configure Prometheus to collect metrics from the notification service, such as request latency and error rates. Visualize Data : Use the Angular frontend to visualize the collected metrics and provide insights into the notification service's performance. Copy Code // Example of a Prometheus dashboard in Angular import { Component } from '@angular/core'; import { HttpClient } from '@angular/common/http'; @Component({ selector: 'app-prometheus-dashboard', template: ` Prometheus Dashboard {{ metric.name }}: {{ metric.value }} `, }) export class PrometheusDashboardComponent { metrics: any[]; constructor(private http: HttpClient) {} ngOnInit() { this.http.get('http://localhost:9090/metrics') .subscribe((response: any) => { this.metrics = response.data; }); } } Configuring Prometheus Configure Prometheus : Configure Prometheus to collect metrics from the notification service using the prometheus.yml file. Scrape Metrics : Configure Prometheus to scrape metrics from the notification service at regular intervals. Copy Code # Example of a prometheus.yml file global: scrape_interval: 10s evaluation_interval: 10s scrape_configs: - job_name: 'notification_service' static_configs: - targets: ['localhost:3000'] Scalability and Performance Horizontal Scaling : Scale the notification service horizontally by adding more instances to handle increased traffic. Load Balancing : Use a load balancer to distribute incoming traffic across multiple instances of the notification service. Monitoring and Optimization : Continuously monitor the notification service's performance and optimize it as needed to ensure reliability and scalability. By monitoring a notification service with Angular and Prometheus, you can ensure its reliability and performance, providing a better user experience and reducing the risk of downtime.

A ChainMap class is provided for quickly linking a number of mappings so they can be treated as a single unit. It is often much faster than creating a new dictionary and running multiple update() calls. The class can be used to simulate nested scopes and is useful in templating. class collections. ChainMap ( * maps ) ¶ A ChainMap groups multiple dicts or other mappings together to create a single, updateable view. If no maps are specified, a single empty dictionary is provided so that a new chain always has at least one mapping. The underlying mappings are stored in a list. That list is public and can be accessed or updated using the maps attribute. There is no other state. Lookups search the underlying mappings successively until a key is found. In contrast, writes, updates, and deletions only operate on the first mapping. A ChainMap incorporates the underlying mappings by reference. So, if one of the underlying mappings gets updated, those changes will be reflected in ChainMap . All of the usual dictionary methods are supported. In addition, there is a maps attribute, a method for creating new subcontexts, and a property for accessing all but the first mapping: maps ¶ A user updateable list of mappings. The list is ordered from first-searched to last-searched. It is the only stored state and can be modified to change which mappings are searched. The list should always contain at least one mapping. new_child ( m = None , ** kwargs ) ¶ Returns a new ChainMap containing a new map followed by all of the maps in the current instance. If m is specified, it becomes the new map at the front of the list of mappings; if not specified, an empty dict is used, so that a call to d.new_child() is equivalent to: ChainMap({}, *d.maps) . If any keyword arguments are specified, they update passed map or new empty dict. This method is used for creating subcontexts that can be updated without altering values in any of the parent mappings. Changed in version 3.4: The optional m parameter was added. Changed in version 3.10: Keyword arguments support was added. parents ¶ Property returning a new ChainMap containing all of the maps in the current instance except the first one. This is useful for skipping the first map in the search. Use cases are similar to those for the nonlocal keyword used in nested scopes . The use cases also parallel those for the built-in super() function. A reference to d.parents is equivalent to: ChainMap(*d.maps[1:]) . Note, the iteration order of a ChainMap is determined by scanning the mappings last to first: >>> baseline = { 'music' : 'bach' , 'art' : 'rembrandt' } >>> adjustments = { 'art' : 'van gogh' , 'opera' : 'carmen' } >>> list ( ChainMap ( adjustments , baseline )) ['music', 'art', 'opera'] This gives the same ordering as a series of dict.update() calls starting with the last mapping: >>> combined = baseline . copy () >>> combined . update ( adjustments ) >>> list ( combined ) ['music', 'art', 'opera'] Changed in version 3.9: Added support for | and |= operators, specified in PEP 584 . See also The MultiContext class in the Enthought CodeTools package has options to support writing to any mapping in the chain. Django’s Context class for templating is a read-only chain of mappings. It also features pushing and popping of contexts similar to the new_child() method and the parents property. The Nested Contexts recipe has options to control whether writes and other mutations apply only to the first mapping or to any mapping in the chain. A greatly simplified read-only version of Chainmap . ChainMap Examples and Recipes ¶ This section shows various approaches to working with chained maps. Example of simulating Python’s internal lookup chain: import builtins pylookup = ChainMap ( locals (), globals (), vars ( builtins )) Example of letting user specified command-line arguments take precedence over environment variables which in turn take precedence over default values: import os , argparse defaults = { 'color' : 'red' , 'user' : 'guest' } parser = argparse . ArgumentParser () parser . add_argument ( '-u' , '--user' ) parser . add_argument ( '-c' , '--color' ) namespace = parser . parse_args () command_line_args = { k : v for k , v in vars ( namespace ) . items () if v is not None } combined = ChainMap ( command_line_args , os . environ , defaults ) print ( combined [ 'color' ]) print ( combined [ 'user' ]) Example patterns for using the ChainMap class to simulate nested contexts: c = ChainMap () # Create root context d = c . new_child () # Create nested child context e = c . new_child () # Child of c, independent from d e . maps [ 0 ] # Current context dictionary -- like Python's locals() e . maps [ - 1 ] # Root context -- like Python's globals() e . parents # Enclosing context chain -- like Python's nonlocals d [ 'x' ] = 1 # Set value in current context d [ 'x' ] # Get first key in the chain of contexts del d [ 'x' ] # Delete from current context list ( d ) # All nested values k in d # Check all nested values len ( d ) # Number of nested values d . items () # All nested items dict ( d ) # Flatten into a regular dictionary The ChainMap class only makes updates (writes and deletions) to the first mapping in the chain while lookups will search the full chain. However, if deep writes and deletions are desired, it is easy to make a subclass that updates keys found deeper in the chain: class DeepChainMap ( ChainMap ): 'Variant of ChainMap that allows direct updates to inner scopes' def __setitem__ ( self , key , value ): for mapping in self . maps : if key in mapping : mapping [ key ] = value return self . maps [ 0 ][ key ] = value def __delitem__ ( self , key ): for mapping in self . maps : if key in mapping : del mapping [ key ] return raise KeyError ( key ) >>> d = DeepChainMap ({ 'zebra' : 'black' }, { 'elephant' : 'blue' }, { 'lion' : 'yellow' }) >>> d [ 'lion' ] = 'orange' # update an existing key two levels down >>> d [ 'snake' ] = 'red' # new keys get added to the topmost dict >>> del d [ 'elephant' ] # remove an existing key one level down >>> d # display result DeepChainMap ({ 'zebra' : 'black' , 'snake' : 'red' }, {}, { 'lion' : 'orange' }) Counter objects ¶ A counter tool is provided to support convenient and rapid tallies. For example: >>> # Tally occurrences of words in a list >>> cnt = Counter () >>> for word in [ 'red' , 'blue' , 'red' , 'green' , 'blue' , 'blue' ]: ... cnt [ word ] += 1 ... >>> cnt Counter({'blue': 3, 'red': 2, 'green': 1}) >>> # Find the ten most common words in Hamlet >>> import re >>> words = re . findall ( r '\w+' , open ( 'hamlet.txt' ) . read () . lower ()) >>> Counter ( words ) . most_common ( 10 ) [('the', 1143), ('and', 966), ('to', 762), ('of', 669), ('i', 631), ('you', 554), ('a', 546), ('my', 514), ('hamlet', 471), ('in', 451)] class collections. Counter ( [ iterable-or-mapping ] ) ¶ A Counter is a dict subclass for counting hashable objects. It is a collection where elements are stored as dictionary keys and their counts are stored as dictionary values. Counts are allowed to be any integer value including zero or negative counts. The Counter class is similar to bags or multisets in other languages. Elements are counted from an iterable or initialized from another mapping (or counter): >>> c = Counter () # a new, empty counter >>> c = Counter ( 'gallahad' ) # a new counter from an iterable >>> c = Counter ({ 'red' : 4 , 'blue' : 2 }) # a new counter from a mapping >>> c = Counter ( cats = 4 , dogs = 8 ) # a new counter from keyword args Counter objects have a dictionary interface except that they return a zero count for missing items instead of raising a KeyError : >>> c = Counter ([ 'eggs' , 'ham' ]) >>> c [ 'bacon' ] # count of a missing element is zero 0 Setting a count to zero does not remove an element from a counter. Use del to remove it entirely: >>> c [ 'sausage' ] = 0 # counter entry with a zero count >>> del c [ 'sausage' ] # del actually removes the entry Added in version 3.1. Changed in version 3.7: As a dict subclass, Counter inherited the capability to remember insertion order. Math operations on Counter objects also preserve order. Results are ordered according to when an element is first encountered in the left operand and then by the order encountered in the right operand. Counter objects support additional methods beyond those available for all dictionaries: elements ( ) ¶ Return an iterator over elements repeating each as many times as its count. Elements are returned in the order first encountered. If an element’s count is less than one, elements() will ignore it. >>> c = Counter ( a = 4 , b = 2 , c = 0 , d =- 2 ) >>> sorted ( c . elements ()) ['a', 'a', 'a', 'a', 'b', 'b'] most_common ( [ n ] ) ¶ Return a list of the n most common elements and their counts from the most common to the least. If n is omitted or None , most_common() returns all elements in the counter. Elements with equal counts are ordered in the order first encountered: >>> Counter ( 'abracadabra' ) . most_common ( 3 ) [('a', 5), ('b', 2), ('r', 2)] subtract ( [ iterable-or-mapping ] ) ¶ Elements are subtracted from an iterable or from another mapping (or counter). Like dict.update() but subtracts counts instead of replacing them. Both inputs and outputs may be zero or negative. >>> c = Counter ( a = 4 , b = 2 , c = 0 , d =- 2 ) >>> d = Counter ( a = 1 , b = 2 , c = 3 , d = 4 ) >>> c . subtract ( d ) >>> c Counter({'a': 3, 'b': 0, 'c': -3, 'd': -6}) Added in version 3.2. total ( ) ¶ Compute the sum of the counts. >>> c = Counter ( a = 10 , b = 5 , c = 0 ) >>> c . total () 15 Added in version 3.10. The usual dictionary methods are available for Counter objects except for two which work differently for counters. fromkeys ( iterable ) ¶ This class method is not implemented for Counter objects. update ( [ iterable-or-mapping ] ) ¶ Elements are counted from an iterable or added-in from another mapping (or counter). Like dict.update() but adds counts instead of replacing them. Also, the iterable is expected to be a sequence of elements, not a sequence of (key, value) pairs. Counters support rich comparison operators for equality, subset, and superset relationships: == , != , < , <= , > , >= . All of those tests treat missing elements as having zero counts so that Counter(a=1) == Counter(a=1, b=0) returns true. Changed in version 3.10: Rich comparison operations were added. Changed in version 3.10: In equality tests, missing elements are treated as having zero counts. Formerly, Counter(a=3) and Counter(a=3, b=0) were considered distinct. Common patterns for working with Counter objects: c . total () # total of all counts c . clear () # reset all counts list ( c ) # list unique elements set ( c ) # convert to a set dict ( c ) # convert to a regular dictionary c . items () # access the (elem, cnt) pairs Counter ( dict ( list_of_pairs )) # convert from a list of (elem, cnt) pairs c . most_common ()[: - n - 1 : - 1 ] # n least common elements + c # remove zero and negative counts Several mathematical operations are provided for combining Counter objects to produce multisets (counters that have counts greater than zero). Addition and subtraction combine counters by adding or subtracting the counts of corresponding elements. Intersection and union return the minimum and maximum of corresponding counts. Equality and inclusion compare corresponding counts. Each operation can accept inputs with signed counts, but the output will exclude results with counts of zero or less. >>> c = Counter ( a = 3 , b = 1 ) >>> d = Counter ( a = 1 , b = 2 ) >>> c + d # add two counters together: c[x] + d[x] Counter({'a': 4, 'b': 3}) >>> c - d # subtract (keeping only positive counts) Counter({'a': 2}) >>> c & d # intersection: min(c[x], d[x]) Counter({'a': 1, 'b': 1}) >>> c | d # union: max(c[x], d[x]) Counter({'a': 3, 'b': 2}) >>> c == d # equality: c[x] == d[x] False >>> c <= d # inclusion: c[x] <= d[x] False Unary addition and subtraction are shortcuts for adding an empty counter or subtracting from an empty counter. >>> c = Counter ( a = 2 , b =- 4 ) >>> + c Counter({'a': 2}) >>> - c Counter({'b': 4}) Added in version 3.3: Added support for unary plus, unary minus, and in-place multiset operations. Note Counters were primarily designed to work with positive integers to represent running counts; however, care was taken to not unnecessarily preclude use cases needing other types or negative values. To help with those use cases, this section documents the minimum range and type restrictions. The Counter class itself is a dictionary subclass with no restrictions on its keys and values. The values are intended to be numbers representing counts, but you could store anything in the value field. The most_common() method requires only that the values be orderable. For in-place operations such as c[key] += 1 , the value type need only support addition and subtraction. So fractions, floats, and decimals would work and negative values are supported. The same is also true for update() and subtract() which allow negative and zero values for both inputs and outputs. The multiset methods are designed only for use cases with positive values. The inputs may be negative or zero, but only outputs with positive values are created. There are no type restrictions, but the value type needs to support addition, subtraction, and comparison. The elements() method requires integer counts. It ignores zero and negative counts. See also Bag class in Smalltalk. Wikipedia entry for Multisets . C++ multisets tutorial with examples. For mathematical operations on multisets and their use cases, see Knuth, Donald. The Art of Computer Programming Volume II, Section 4.6.3, Exercise 19 . To enumerate all distinct multisets of a given size over a given set of elements, see itertools.combinations_with_replacement() : map ( Counter , combinations_with_replacement ( 'ABC' , 2 )) # --> AA AB AC BB BC CC deque objects ¶ class collections. deque ( [ iterable [ , maxlen ] ] ) ¶ Returns a new deque object initialized left-to-right (using append() ) with data from iterable . If iterable is not specified, the new deque is empty. Deques are a generalization of stacks and queues (the name is pronounced “deck” and is short for “double-ended queue”). Deques support thread-safe, memory efficient appends and pops from either side of the deque with approximately the same O (1) performance in either direction. Though list objects support similar operations, they are optimized for fast fixed-length operations and incur O ( n ) memory movement costs for pop(0) and insert(0, v) operations which change both the size and position of the underlying data representation. If maxlen is not specified or is None , deques may grow to an arbitrary length. Otherwise, the deque is bounded to the specified maximum length. Once a bounded length deque is full, when new items are added, a corresponding number of items are discarded from the opposite end. Bounded length deques provide functionality similar to the tail filter in Unix. They are also useful for tracking transactions and other pools of data where only the most recent activity is of interest. Deque objects support the following methods: append ( x ) ¶ Add x to the right side of the deque. appendleft ( x ) ¶ Add x to the left side of the deque. clear ( ) ¶ Remove all elements from the deque leaving it with length 0. copy ( ) ¶ Create a shallow copy of the deque. Added in version 3.5. count ( x ) ¶ Count the number of deque elements equal to x . Added in version 3.2. extend ( iterable ) ¶ Extend the right side of the deque by appending elements from the iterable argument. extendleft ( iterable ) ¶ Extend the left side of the deque by appending elements from iterable . Note, the series of left appends results in reversing the order of elements in the iterable argument. index ( x [ , start [ , stop ] ] ) ¶ Return the position of x in the deque (at or after index start and before index stop ). Returns the first match or raises ValueError if not found. Added in version 3.5. insert ( i , x ) ¶ Insert x into the deque at position i . If the insertion would cause a bounded deque to grow beyond maxlen , an IndexError is raised. Added in version 3.5. pop ( ) ¶ Remove and return an element from the right side of the deque. If no elements are present, raises an IndexError . popleft ( ) ¶ Remove and return an element from the left side of the deque. If no elements are present, raises an IndexError . remove ( value ) ¶ Remove the first occurrence of value . If not found, raises a ValueError . reverse ( ) ¶ Reverse the elements of the deque in-place and then return None . Added in version 3.2. rotate ( n = 1 ) ¶ Rotate the deque n steps to the right. If n is negative, rotate to the left. When the deque is not empty, rotating one step to the right is equivalent to d.appendleft(d.pop()) , and rotating one step to the left is equivalent to d.append(d.popleft()) . Deque objects also provide one read-only attribute: maxlen ¶ Maximum size of a deque or None if unbounded. Added in version 3.1. In addition to the above, deques support iteration, pickling, len(d) , reversed(d) , copy.copy(d) , copy.deepcopy(d) , membership testing with the in operator, and subscript references such as d[0] to access the first element. Indexed access is O (1) at both ends but slows to O ( n ) in the middle. For fast random access, use lists instead. Starting in version 3.5, deques support __add__() , __mul__() , and __imul__() . Example: >>> from collections import deque >>> d = deque ( 'ghi' ) # make a new deque with three items >>> for elem in d : # iterate over the deque's elements ... print ( elem . upper ()) G H I >>> d . append ( 'j' ) # add a new entry to the right side >>> d . appendleft ( 'f' ) # add a new entry to the left side >>> d # show the representation of the deque deque(['f', 'g', 'h', 'i', 'j']) >>> d . pop () # return and remove the rightmost item 'j' >>> d . popleft () # return and remove the leftmost item 'f' >>> list ( d ) # list the contents of the deque ['g', 'h', 'i'] >>> d [ 0 ] # peek at leftmost item 'g' >>> d [ - 1 ] # peek at rightmost item 'i' >>> list ( reversed ( d )) # list the contents of a deque in reverse ['i', 'h', 'g'] >>> 'h' in d # search the deque True >>> d . extend ( 'jkl' ) # add multiple elements at once >>> d deque(['g', 'h', 'i', 'j', 'k', 'l']) >>> d . rotate ( 1 ) # right rotation >>> d deque(['l', 'g', 'h', 'i', 'j', 'k']) >>> d . rotate ( - 1 ) # left rotation >>> d deque(['g', 'h', 'i', 'j', 'k', 'l']) >>> deque ( reversed ( d )) # make a new deque in reverse order deque(['l', 'k', 'j', 'i', 'h', 'g']) >>> d . clear () # empty the deque >>> d . pop () # cannot pop from an empty deque Traceback (most recent call last): File "<pyshell#6>" , line 1 , in - toplevel - d . pop () IndexError : pop from an empty deque >>> d . extendleft ( 'abc' ) # extendleft() reverses the input order >>> d deque(['c', 'b', 'a']) deque Recipes ¶ This section shows various approaches to working with deques. Bounded length deques provide functionality similar to the tail filter in Unix: def tail ( filename , n = 10 ): 'Return the last n lines of a file' with open ( filename ) as f : return deque ( f , n ) Another approach to using deques is to maintain a sequence of recently added elements by appending to the right and popping to the left: def moving_average ( iterable , n = 3 ): # moving_average([40, 30, 50, 46, 39, 44]) --> 40.0 42.0 45.0 43.0 # https://en.wikipedia.org/wiki/Moving_average it = iter ( iterable ) d = deque ( itertools . islice ( it , n - 1 )) d . appendleft ( 0 ) s = sum ( d ) for elem in it : s += elem - d . popleft () d . append ( elem ) yield s / n A round-robin scheduler can be implemented with input iterators stored in a deque . Values are yielded from the active iterator in position zero. If that iterator is exhausted, it can be removed with popleft() ; otherwise, it can be cycled back to the end with the rotate() method: def roundrobin ( * iterables ): "roundrobin('ABC', 'D', 'EF') --> A D E B F C" iterators = deque ( map ( iter , iterables )) while iterators : try : while True : yield next ( iterators [ 0 ]) iterators . rotate ( - 1 ) except StopIteration : # Remove an exhausted iterator. iterators . popleft () The rotate() method provides a way to implement deque slicing and deletion. For example, a pure Python implementation of del d[n] relies on the rotate() method to position elements to be popped: def delete_nth ( d , n ): d . rotate ( - n ) d . popleft () d . rotate ( n ) To implement deque slicing, use a similar approach applying rotate() to bring a target element to the left side of the deque. Remove old entries with popleft() , add new entries with extend() , and then reverse the rotation. With minor variations on that approach, it is easy to implement Forth style stack manipulations such as dup , drop , swap , over , pick , rot , and roll . defaultdict objects ¶ class collections. defaultdict ( default_factory=None , / [ , ... ] ) ¶ Return a new dictionary-like object. defaultdict is a subclass of the built-in dict class. It overrides one method and adds one writable instance variable. The remaining functionality is the same as for the dict class and is not documented here. The first argument provides the initial value for the default_factory attribute; it defaults to None . All remaining arguments are treated the same as if they were passed to the dict constructor, including keyword arguments. defaultdict objects support the following method in addition to the standard dict operations: __missing__ ( key ) ¶ If the default_factory attribute is None , this raises a KeyError exception with the key as argument. If default_factory is not None , it is called without arguments to provide a default value for the given key , this value is inserted in the dictionary for the key , and returned. If calling default_factory raises an exception this exception is propagated unchanged. This method is called by the __getitem__() method of the dict class when the requested key is not found; whatever it returns or raises is then returned or raised by __getitem__() . Note that __missing__() is not called for any operations besides __getitem__() . This means that get() will, like normal dictionaries, return None as a default rather than using default_factory . defaultdict objects support the following instance variable: default_factory ¶ This attribute is used by the __missing__() method; it is initialized from the first argument to the constructor, if present, or to None , if absent. Changed in version 3.9: Added merge ( | ) and update ( |= ) operators, specified in PEP 584 . defaultdict Examples ¶ Using list as the default_factory , it is easy to group a sequence of key-value pairs into a dictionary of lists: >>> s = [( 'yellow' , 1 ), ( 'blue' , 2 ), ( 'yellow' , 3 ), ( 'blue' , 4 ), ( 'red' , 1 )] >>> d = defaultdict ( list ) >>> for k , v in s : ... d [ k ] . append ( v ) ... >>> sorted ( d . items ()) [('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])] When each key is encountered for the first time, it is not already in the mapping; so an entry is automatically created using the default_factory function which returns an empty list . The list.append() operation then attaches the value to the new list. When keys are encountered again, the look-up proceeds normally (returning the list for that key) and the list.append() operation adds another value to the list. This technique is simpler and faster than an equivalent technique using dict.setdefault() : >>> d = {} >>> for k , v in s : ... d . setdefault ( k , []) . append ( v ) ... >>> sorted ( d . items ()) [('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])] Setting the default_factory to int makes the defaultdict useful for counting (like a bag or multiset in other languages): >>> s = 'mississippi' >>> d = defaultdict ( int ) >>> for k in s : ... d [ k ] += 1 ... >>> sorted ( d . items ()) [('i', 4), ('m', 1), ('p', 2), ('s', 4)] When a letter is first encountered, it is missing from the mapping, so the default_factory function calls int() to supply a default count of zero. The increment operation then builds up the count for each letter. The function int() which always returns zero is just a special case of constant functions. A faster and more flexible way to create constant functions is to use a lambda function which can supply any constant value (not just zero): >>> def constant_factory ( value ): ... return lambda : value ... >>> d = defaultdict ( constant_factory ( '<missing>' )) >>> d . update ( name = 'John' , action = 'ran' ) >>> ' %(name)s %(action)s to %(object)s ' % d 'John ran to <missing>' Setting the default_factory to set makes the defaultdict useful for building a dictionary of sets: >>> s = [( 'red' , 1 ), ( 'blue' , 2 ), ( 'red' , 3 ), ( 'blue' , 4 ), ( 'red' , 1 ), ( 'blue' , 4 )] >>> d = defaultdict ( set ) >>> for k , v in s : ... d [ k ] . add ( v ) ... >>> sorted ( d . items ()) [('blue', {2, 4}), ('red', {1, 3})] namedtuple() Factory Function for Tuples with Named Fields ¶ Named tuples assign meaning to each position in a tuple and allow for more readable, self-documenting code. They can be used wherever regular tuples are used, and they add the ability to access fields by name instead of position index. collections. namedtuple ( typename , field_names , * , rename = False , defaults = None , module = None ) ¶ Returns a new tuple subclass named typename . The new subclass is used to create tuple-like objects that have fields accessible by attribute lookup as well as being indexable and iterable. Instances of the subclass also have a helpful docstring (with typename and field_names ) and a helpful __repr__() method which lists the tuple contents in a name=value format. The field_names are a sequence of strings such as ['x', 'y'] . Alternatively, field_names can be a single string with each fieldname separated by whitespace and/or commas, for example 'x y' or 'x, y' . Any valid Python identifier may be used for a fieldname except for names starting with an underscore. Valid identifiers consist of letters, digits, and underscores but do not start with a digit or underscore and cannot be a keyword such as class , for , return , global , pass , or raise . If rename is true, invalid fieldnames are automatically replaced with positional names. For example, ['abc', 'def', 'ghi', 'abc'] is converted to ['abc', '_1', 'ghi', '_3'] , eliminating the keyword def and the duplicate fieldname abc . defaults can be None or an iterable of default values. Since fields with a default value must come after any fields without a default, the defaults are applied to the rightmost parameters. For example, if the fieldnames are ['x', 'y', 'z'] and the defaults are (1, 2) , then x will be a required argument, y will default to 1 , and z will default to 2 . If module is defined, the __module__ attribute of the named tuple is set to that value. Named tuple instances do not have per-instance dictionaries, so they are lightweight and require no more memory than regular tuples. To support pickling, the named tuple class should be assigned to a variable that matches typename . Changed in version 3.1: Added support for rename . Changed in version 3.6: The verbose and rename parameters became keyword-only arguments . Changed in version 3.6: Added the module parameter. Changed in version 3.7: Removed the verbose parameter and the _source attribute. Changed in version 3.7: Added the defaults parameter and the _field_defaults attribute. >>> # Basic example >>> Point = namedtuple ( 'Point' , [ 'x' , 'y' ]) >>> p = Point ( 11 , y = 22 ) # instantiate with positional or keyword arguments >>> p [ 0 ] + p [ 1 ] # indexable like the plain tuple (11, 22) 33 >>> x , y = p # unpack like a regular tuple >>> x , y (11, 22) >>> p . x + p . y # fields also accessible by name 33 >>> p # readable __repr__ with a name=value style Point(x=11, y=22) Named tuples are especially useful for assigning field names to result tuples returned by the csv or sqlite3 modules: EmployeeRecord = namedtuple ( 'EmployeeRecord' , 'name, age, title, department, paygrade' ) import csv for emp in map ( EmployeeRecord . _make , csv . reader ( open ( "employees.csv" , "rb" ))): print ( emp . name , emp . title ) import sqlite3 conn = sqlite3 . connect ( '/companydata' ) cursor = conn . cursor () cursor . execute ( 'SELECT name, age, title, department, paygrade FROM employees' ) for emp in map ( EmployeeRecord . _make , cursor . fetchall ()): print ( emp . name , emp . title ) In addition to the methods inherited from tuples, named tuples support three additional methods and two attributes. To prevent conflicts with field names, the method and attribute names start with an underscore. classmethod somenamedtuple. _make ( iterable ) ¶ Class method that makes a new instance from an existing sequence or iterable. >>> t = [ 11 , 22 ] >>> Point . _make ( t ) Point(x=11, y=22) somenamedtuple. _asdict ( ) ¶ Return a new dict which maps field names to their corresponding values: >>> p = Point ( x = 11 , y = 22 ) >>> p . _asdict () {'x': 11, 'y': 22} Changed in version 3.1: Returns an OrderedDict instead of a regular dict . Changed in version 3.8: Returns a regular dict instead of an OrderedDict . As of Python 3.7, regular dicts are guaranteed to be ordered. If the extra features of OrderedDict are required, the suggested remediation is to cast the result to the desired type: OrderedDict(nt._asdict()) . somenamedtuple. _replace ( ** kwargs ) ¶ Return a new instance of the named tuple replacing specified fields with new values: >>> p = Point ( x = 11 , y = 22 ) >>> p . _replace ( x = 33 ) Point(x=33, y=22) >>> for partnum , record in inventory . items (): ... inventory [ partnum ] = record . _replace ( price = newprices [ partnum ], timestamp = time . now ()) Named tuples are also supported by generic function copy.replace() . Changed in version 3.13: Raise TypeError instead of ValueError for invalid keyword arguments. somenamedtuple. _fields ¶ Tuple of strings listing the field names. Useful for introspection and for creating new named tuple types from existing named tuples. >>> p . _fields # view the field names ('x', 'y') >>> Color = namedtuple ( 'Color' , 'red green blue' ) >>> Pixel = namedtuple ( 'Pixel' , Point . _fields + Color . _fields ) >>> Pixel ( 11 , 22 , 128 , 255 , 0 ) Pixel(x=11, y=22, red=128, green=255, blue=0) somenamedtuple. _field_defaults ¶ Dictionary mapping field names to default values. >>> Account = namedtuple ( 'Account' , [ 'type' , 'balance' ], defaults = [ 0 ]) >>> Account . _field_defaults {'balance': 0} >>> Account ( 'premium' ) Account(type='premium', balance=0) To retrieve a field whose name is stored in a string, use the getattr() function: >>> getattr ( p , 'x' ) 11 To convert a dictionary to a named tuple, use the double-star-operator (as described in Unpacking Argument Lists ): >>> d = { 'x' : 11 , 'y' : 22 } >>> Point ( ** d ) Point(x=11, y=22) Since a named tuple is a regular Python class, it is easy to add or change functionality with a subclass. Here is how to add a calculated field and a fixed-width print format: >>> class Point ( namedtuple ( 'Point' , [ 'x' , 'y' ])): ... __slots__ = () ... @property ... def hypot ( self ): ... return ( self . x ** 2 + self . y ** 2 ) ** 0.5 ... def __str__ ( self ): ... return 'Point: x= %6.3f y= %6.3f hypot= %6.3f ' % ( self . x , self . y , self . hypot ) >>> for p in Point ( 3 , 4 ), Point ( 14 , 5 / 7 ): ... print ( p ) Point: x= 3.000 y= 4.000 hypot= 5.000 Point: x=14.000 y= 0.714 hypot=14.018 The subclass shown above sets __slots__ to an empty tuple. This helps keep memory requirements low by preventing the creation of instance dictionaries. Subclassing is not useful for adding new, stored fields. Instead, simply create a new named tuple type from the _fields attribute: >>> Point3D = namedtuple ( 'Point3D' , Point . _fields + ( 'z' ,)) Docstrings can be customized by making direct assignments to the __doc__ fields: >>> Book = namedtuple ( 'Book' , [ 'id' , 'title' , 'authors' ]) >>> Book . __doc__ += ': Hardcover book in active collection' >>> Book . id . __doc__ = '13-digit ISBN' >>> Book . title . __doc__ = 'Title of first printing' >>> Book . authors . __doc__ = 'List of authors sorted by last name' Changed in version 3.5: Property docstrings became writeable. See also See typing.NamedTuple for a way to add type hints for named tuples. It also provides an elegant notation using the class keyword: class Component ( NamedTuple ): part_number : int weight : float description : Optional [ str ] = None See types.SimpleNamespace() for a mutable namespace based on an underlying dictionary instead of a tuple. The dataclasses module provides a decorator and functions for automatically adding generated special methods to user-defined classes. OrderedDict objects ¶ Ordered dictionaries are just like regular dictionaries but have some extra capabilities relating to ordering operations. They have become less important now that the built-in dict class gained the ability to remember insertion order (this new behavior became guaranteed in Python 3.7). Some differences from dict still remain: The regular dict was designed to be very good at mapping operations. Tracking insertion order was secondary. The OrderedDict was designed to be good at reordering operations. Space efficiency, iteration speed, and the performance of update operations were secondary. The OrderedDict algorithm can handle frequent reordering operations better than dict . As shown in the recipes below, this makes it suitable for implementing various kinds of LRU caches. The equality operation for OrderedDict checks for matching order. A regular dict can emulate the order sensitive equality test with p == q and all(k1 == k2 for k1, k2 in zip(p, q)) . The popitem() method of OrderedDict has a different signature. It accepts an optional argument to specify which item is popped. A regular dict can emulate OrderedDict’s od.popitem(last=True) with d.popitem() which is guaranteed to pop the rightmost (last) item. A regular dict can emulate OrderedDict’s od.popitem(last=False) with (k := next(iter(d)), d.pop(k)) which will return and remove the leftmost (first) item if it exists. OrderedDict has a move_to_end() method to efficiently reposition an element to an endpoint. A regular dict can emulate OrderedDict’s od.move_to_end(k, last=True) with d[k] = d.pop(k) which will move the key and its associated value to the rightmost (last) position. A regular dict does not have an efficient equivalent for OrderedDict’s od.move_to_end(k, last=False) which moves the key and its associated value to the leftmost (first) position. Until Python 3.8, dict lacked a __reversed__() method. class collections. OrderedDict ( [ items ] ) ¶ Return an instance of a dict subclass that has methods specialized for rearranging dictionary order. Added in version 3.1. popitem ( last = True ) ¶ The popitem() method for ordered dictionaries returns and removes a (key, value) pair. The pairs are returned in LIFO order if last is true or FIFO order if false. move_to_end ( key , last = True ) ¶ Move an existing key to either end of an ordered dictionary. The item is moved to the right end if last is true (the default) or to the beginning if last is false. Raises KeyError if the key does not exist: >>> d = OrderedDict . fromkeys ( 'abcde' ) >>> d . move_to_end ( 'b' ) >>> '' . join ( d ) 'acdeb' >>> d . move_to_end ( 'b' , last = False ) >>> '' . join ( d ) 'bacde' Added in version 3.2. In addition to the usual mapping methods, ordered dictionaries also support reverse iteration using reversed() . Equality tests between OrderedDict objects are order-sensitive and are roughly equivalent to list(od1.items())==list(od2.items()) . Equality tests between OrderedDict objects and other Mapping objects are order-insensitive like regular dictionaries. This allows OrderedDict objects to be substituted anywhere a regular dictionary is used. Changed in version 3.5: The items, keys, and values views of OrderedDict now support reverse iteration using reversed() . Changed in version 3.6: With the acceptance of PEP 468 , order is retained for keyword arguments passed to the OrderedDict constructor and its update() method. Changed in version 3.9: Added merge ( | ) and update ( |= ) operators, specified in PEP 584 . OrderedDict Examples and Recipes ¶ It is straightforward to create an ordered dictionary variant that remembers the order the keys were last inserted. If a new entry overwrites an existing entry, the original insertion position is changed and moved to the end: class LastUpdatedOrderedDict ( OrderedDict ): 'Store items in the order the keys were last added' def __setitem__ ( self , key , value ): super () . __setitem__ ( key , value ) self . move_to_end ( key ) An OrderedDict would also be useful for implementing variants of functools.lru_cache() : from collections import OrderedDict from time import time class TimeBoundedLRU : "LRU Cache that invalidates and refreshes old entries." def __init__ ( self , func , maxsize = 128 , maxage = 30 ): self . cache = OrderedDict () # { args : (timestamp, result)} self . func = func self . maxsize = maxsize self . maxage = maxage def __call__ ( self , * args ): if args in self . cache : self . cache . move_to_end ( args ) timestamp , result = self . cache [ args ] if time () - timestamp <= self . maxage : return result result = self . func ( * args ) self . cache [ args ] = time (), result if len ( self . cache ) > self . maxsize : self . cache . popitem ( last = False ) return result class MultiHitLRUCache : """ LRU cache that defers caching a result until it has been requested multiple times. To avoid flushing the LRU cache with one-time requests, we don't cache until a request has been made more than once. """ def __init__ ( self , func , maxsize = 128 , maxrequests = 4096 , cache_after = 1 ): self . requests = OrderedDict () # { uncached_key : request_count } self . cache = OrderedDict () # { cached_key : function_result } self . func = func self . maxrequests = maxrequests # max number of uncached requests self . maxsize = maxsize # max number of stored return values self . cache_after = cache_after def __call__ ( self , * args ): if args in self . cache : self . cache . move_to_end ( args ) return self . cache [ args ] result = self . func ( * args ) self . requests [ args ] = self . requests . get ( args , 0 ) + 1 if self . requests [ args ] <= self . cache_after : self . requests . move_to_end ( args ) if len ( self . requests ) > self . maxrequests : self . requests . popitem ( last = False ) else : self . requests . pop ( args , None ) self . cache [ args ] = result if len ( self . cache ) > self . maxsize : self . cache . popitem ( last = False ) return result UserDict objects ¶ The class, UserDict acts as a wrapper around dictionary objects. The need for this class has been partially supplanted by the ability to subclass directly from dict ; however, this class can be easier to work with because the underlying dictionary is accessible as an attribute. class collections. UserDict ( [ initialdata ] ) ¶ Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it to be used for other purposes. In addition to supporting the methods and operations of mappings, UserDict instances provide the following attribute: data ¶ A real dictionary used to store the contents of the UserDict class. UserList objects ¶ This class acts as a wrapper around list objects. It is a useful base class for your own list-like classes which can inherit from them and override existing methods or add new ones. In this way, one can add new behaviors to lists. The need for this class has been partially supplanted by the ability to subclass directly from list ; however, this class can be easier to work with because the underlying list is accessible as an attribute. class collections. UserList ( [ list ] ) ¶ Class that simulates a list. The instance’s contents are kept in a regular list, which is accessible via the data attribute of UserList instances. The instance’s contents are initially set to a copy of list , defaulting to the empty list [] . list can be any iterable, for example a real Python list or a UserList object. In addition to supporting the methods and operations of mutable sequences, UserList instances provide the following attribute: data ¶ A real list object used to store the contents of the UserList class. Subclassing requirements: Subclasses of UserList are expected to offer a constructor which can be called with either no arguments or one argument. List operations which return a new sequence attempt to create an instance of the actual implementation class. To do so, it assumes that the constructor can be called with a single parameter, which is a sequence object used as a data source. If a derived class does not wish to comply with this requirement, all of the special methods supported by this class will need to be overridden; please consult the sources for information about the methods which need to be provided in that case. UserString objects ¶ The class, UserString acts as a wrapper around string objects. The need for this class has been partially supplanted by the ability to subclass directly from str ; however, this class can be easier to work with because the underlying string is accessible as an attribute. class collections. UserString ( seq ) ¶ Class that simulates a string object. The instance’s content is kept in a regular string object, which is accessible via the data attribute of UserString instances. The instance’s contents are initially set to a copy of seq . The seq argument can be any object which can be converted into a string using the built-in str() function. In addition to supporting the methods and operations of strings, UserString instances provide the following attribute: data ¶ A real str object used to store the contents of the UserString class.

(" 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 .

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.

Anjali Arya • September 27, 2024 TABLE OF CONTENTS In this comprehensive tutorial, we will guide you through the process of building a real-time chat application using the powerful MERN stack and integrating SuprSend for seamless notifications. By combining the robust features of MongoDB as our database, Express.js for server-side development, React.js for building a dynamic user interface, and Node.js as our runtime environment, we'll create a highly scalable and efficient chat app. Additionally, we'll leverage the capabilities of SuprSend, a versatile notification platform, to enhance user engagement and provide real-time updates. Some of the business use cases for a real-time chat app are as follows: Instant customer support Efficient team collaboration Quick decision-making Real-time project updates Streamlined internal communication Enhanced customer engagement Seamless sales and lead generation Effective remote team coordination Interactive live events and webinars Personalized user experiences. Github Repo: SuprSend-NotificationAPI/Chatting-App (github.com) Deployed Link: Chirpy Chat (mychttingapp.netlify.app) Setting up the backend: Let's start Setting up the backend. We install the necessary dependencies in the server directory. Copy Code Copied ✔ cd server npm init npm i axios cors express socket.io dotenv bcryptjs Install Nodemon. Nodemon is a Node.js tool that automatically restarts the server after detecting file changes, and Socket.io allows us to configure a real-time connection on the server. Configure Nodemon by adding the start command to the list of scripts in the package.json file. The code snippet below starts the server using Nodemon. Copy Code Copied ✔ "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "nodemon index.js" }, We can now run the server with Nodemon by using the command below. npm start If you are not using nodemon, either run the server with the command "node index.js" or modify the script by adding the start command to the list of scripts in the package.json file as shown below Copy Code Copied ✔ "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "node index.js" }, Modify package.json to make index.js an ECMAScript Module by adding "type": "module". Copy Code Copied ✔ { "name": "backend", "version": "1.0.0", "description": "", "main": "index.js", "type": "module", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "nodemon server.js" }, "author": "", "license": "ISC", "dependencies": { "axios": "^1.4.0", "bcryptjs": "^2.4.3", "cors": "^2.8.5", "dotenv": "^16.1.4", "express": "^4.18.2", } } Enter the following code in index.js: Copy Code Copied ✔ import express from "express"; import dotenv from "dotenv"; const app = express() import { createServer } from "http"; import cors from "cors"; const server = createServer(app); dotenv.config(); const PORT = process.env.PORT || 4000; app.use(express.urlencoded({ extended: true })); app.use(express.json()); app.use(cors()); app.get("/", (req, res) => { res.send("Hey!! This is a sign that the server is running"); }); server.listen(PORT, () => console.log("Server is running on port", PORT)); Setting up the frontend: Navigate into the frontend folder via your terminal and create a new React.js project. Copy Code Copied ✔ cd frontend npx create-react-app ./ Installing dependencies: Install Socket.io client API and React Router. React Router is a popular routing library for React applications. It allows us to handle navigation and routing in a declarative manner within the React components. npm install socket.io-client react-router-dom axios We'll also use react toastify and emoji-mart here. Emoji mart is a npm package used to include emojis in chats. npm install react-toastify emoji-mart @emoji-mart/data @emoji-mart/react Cleaning up unnecessary data: Delete the redundant files such as the logo and the test files from the React app, and update the App.js file to display Hello World as below. Run npm start to verify the app is working fine. Copy Code Copied ✔ function App() { return ( Hello World! ); } export default App; Adding Styles: The following is the CSS code for index.css: Copy Code Copied ✔ * { font-family: "Space Grotesk", sans-serif; box-sizing: border-box; } body { margin: 0; padding: 0; } code { font-family: source-code-pro, Menlo, Monaco, Consolas, "Courier New", monospace; } .input { border: 2px solid #008cba; border-radius: 4px; background-color: #f8f8f8; color: #000; transition: 0.3s; box-sizing: border-box; outline: none; margin: 0 5px; width: 50%; padding: 10px 15px; } .input:focus { border-color: #66afe9; outline: none; } .form { width: 100%; height: 100vh; display: flex; flex-direction: column; align-items: center; justify-content: center; } .form > label { margin-bottom: 15px; } .form > input { width: 70%; padding: 10px 15px; margin-bottom: 15px; } .welcome-container { width: 100%; min-height: 100%; display: flex; align-items: center; justify-content: space-between; padding: 10px; } .btn { padding: 15px; cursor: pointer; margin: 10px; font-size: 16px; outline: none; width: 200px; background-color: #007bff; color: white; text-align: center; text-decoration: none; border-radius: 4px; border: none; transition: all 0.4s ease; } .btn:hover { transform: translateY(-4px); box-shadow: 0 2px 4px rgba(0, 0, 0, 0.2); } Building the frontend: Register & Login page: Let's create Register & Login page: Copy Code Copied ✔ // This is for creating a SignUp page import React from "react"; const Register = () => { const handleRegister = async (e) => { }; return ( Enter your name Enter your email Choose a password Register { }}> Log In ); }; export default Register; // This is for creating a Login page import React from "react"; const Login = () => { const handleLogin = async (e) => { }; return ( Provide your email Enter your password Log In ); }; export default Login; Chat Page: Also, create a folder named pages in src and inside it, create chatpage.js. This page, as the name suggests, is incharge of handling the appearance and functionalities of chatting in app. mkdir pages cd pages touch chatpage.js We’ll write code in it after a while, Lets's add the routes and react-toastify imports in app.js. We'll add the routes using Browser Router. Copy Code Copied ✔ import "./App.css"; import { BrowserRouter, Route, Routes } from "react-router-dom"; import { useContext } from "react"; import { ToastContainer } from "react-toastify"; import "react-toastify/dist/ReactToastify.css"; import Register from "./components/register"; // Add this import Chatpage from "./pages/chatpage"; import Login from "./components/login"; // Add this function App() { return ( } /> } /> } /> ); } export default App; // Also modify index.js file inside src as shown below: import React from "react"; import ReactDOM from "react-dom/client"; import "./index.css"; import App from "./App"; import reportWebVitals from "./reportWebVitals"; import { BrowserRouter } from "react-router-dom"; const root = ReactDOM.createRoot(document.getElementById("root")); root.render( // // ); // If you want to start measuring performance in your app, pass a function // to log results (for example: reportWebVitals(console.log)) // or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals reportWebVitals(); Using Context API: We will use context api for keeping authentication and user information. Create a folder named context in src, and create context.js inside it. Copy Code Copied ✔ import React, { createContext, useState, useEffect } from "react"; const AuthContext = createContext(); const AuthProvider = ({ children }) => { const [isAuthenticated, setIsAuthenticated] = useState(false); const [user, setUser] = useState(); const [chats, setChats] = useState(); const [selectedChat, setSelectedChat] = useState(); useEffect(() => { const loggedInUser = JSON.parse(localStorage.getItem("user")); setUser(loggedInUser); }, []); return ( {children} ); }; export { AuthContext, AuthProvider }; Protecting the routes: Now to protect our chatpage route from unauthorized access, we will create a protected route component. Copy Code Copied ✔ import { useContext } from "react"; import { AuthContext } from "../context/context"; import {Navigate} from "react-router-dom" function ProtectedRoute({ children, ...props }) { const { isAuthenticated } = useContext(AuthContext); if (!isAuthenticated) { return } return children; } export default ProtectedRoute; Above part ensures that only a logged in user can navigate to chat page. Now the App.js will be modified to redirect to chatpage when a user is logged in. If an unauthorised user tries to access the chatpage route, he will be redirected to login page. Copy Code Copied ✔ import "./App.css"; import { BrowserRouter, Route, Routes } from "react-router-dom"; import { useContext } from "react"; import { ToastContainer } from "react-toastify"; import "react-toastify/dist/ReactToastify.css"; import Register from "./components/register"; import Chatpage from "./pages/chatpage"; import Login from "./components/login"; import { AuthProvider } from "./context/context"; // Add this import ProtectedRoute from "./components/protectedroute"; //Add this function App() { return ( } /> } /> } /> ); } export default App; Now, we’ll complete login and register components. Let’s modify login and register components to setup the useNavigate hook and handle login and register functionalities: Register.js: Copy Code Copied ✔ import React, { useState, useEffect, useContext } from "react"; import { AuthContext } from "../context/context"; import axios from "axios"; import { useNavigate } from "react-router-dom"; import { toast } from "react-toastify"; const Register = () => { const { isAuthenticated,setIsAuthenticated} = useContext(AuthContext); const [name, setName] = useState(""); // Add this const [email, setEmail] = useState(""); // Add this const [password, setPassword] = useState(""); // Add this const navigate = useNavigate(); const getUserFromLocalStorage = () => { const result = localStorage.getItem("user"); const user = result ? JSON.parse(result) : null; return user; }; useEffect(() => { if (getUserFromLocalStorage("user")) { setIsAuthenticated(true) navigate("/"); } }, [navigate]); const handleRegister = async (e) => { e.preventDefault(); try { const { data } = await axios.post( `${process.env.REACT_APP_URL}/auth/register`, { name, email, password, }, { headers: { "Content-Type": "application/json", }, } ); console.log(data); toast.success("Success!", { duration: 5000, isClosable: true, position: toast.POSITION.TOP_CENTER, }); localStorage.setItem("user", JSON.stringify(data)); navigate("/login"); } catch (error) { console.log(error.response.data.error); toast.error(error.response.data.error, { duration: 5000, isClosable: true, position: toast.POSITION.TOP_CENTER, }); } }; return ( Enter your name setName(e.target.value)} value={name} /> Enter your email setEmail(e.target.value)} value={email} /> Choose a password setPassword(e.target.value)} /> Register { console.log("nav to loggiinn") navigate("/login") }}> Log In ); }; export default Register; Login.js: Copy Code Copied ✔ import React, { useContext, useState } from "react"; import { toast } from "react-toastify"; import axios from "axios"; import { useNavigate } from "react-router-dom"; import { AuthContext } from "../context/context"; // Add this const Login = () => { const { setIsAuthenticated } = useContext(AuthContext); const [email, setEmail] = useState(""); // Add this const [password, setPassword] = useState(""); // Add this const navigate = useNavigate(); const handleLogin = async (e) => { e.preventDefault(); try { const { data } = await axios.post( `${process.env.REACT_APP_URL}/auth/login`, { email, password, }, { headers: { "Content-Type": "application/json", }, } ); console.log(data); setIsAuthenticated(true) toast.success(`Welcome! ${data.name}. Please wait...`, { duration: 5000, isClosable: true, position: toast.POSITION.TOP_CENTER, }); localStorage.setItem("user", JSON.stringify(data)); setTimeout(() => { navigate("/"); }, 4000); } catch (error) { console.log(error.response.data.error); setIsAuthenticated(false) toast.error(error.response.data.error, { duration: 5000, isClosable: true, position: toast.POSITION.TOP_CENTER, }); } }; return ( Provide your email setEmail(e.target.value)} value={email} /> Enter your password setPassword(e.target.value)} /> Log In ); }; export default Login; Completing the ChatPage: Let's create chatpage for the app. Put the following code in pages/chatpage.js: Copy Code Copied ✔ import { useContext, useState } from "react"; import ChatContainer from "../components/ChatContainer"; import MyChats from "../components/MyChats"; import { AuthContext } from "../context/context"; import SideBar from "../components/sidebar"; const Chatpage = () => { const { user } = useContext(AuthContext); const [fetchAgain, setFetchAgain] = useState(false); return ( {user && } {user && } {user && } ); }; export default Chatpage; Now, create Chatcontainer.js, Mychats.js,Groupchatmodal.js, Scrollablechat.js, singlechat.js, sidebar.js, updategroupchatmodel.js, userbadgeitem.js and userlistitem.js files inside components folder. Also create a .env file in the root directory( the parent directory containing public,src etc ) and add the following content REACT_APP_URL=http://localhost:4000 Backend Development Since our basic frontend part is ready, let's move on to the backend. In this app, we’ll use jwt for authentication and authorization. Including Mongodb, Mongoose, JWT: Install mongodb driver, mongoose and jsonwebtoken. npm install mongoose mongodb jsonwebtoken * Add the following code in index.js of backend. Copy Code Copied ✔ import express from "express"; import dotenv from "dotenv"; const app = express(); import mongoose from "mongoose"; //... Rest of the imports dotenv.config(); const PORT = process.env.PORT || 4000; app.use(cors()); app.use(express.urlencoded({ extended: true })); app.use(express.json()); // Add this mongoose .connect(process.env.MONGODB_URI, { useNewUrlParser: true, useUnifiedTopology: true, }) .then(() => console.log("Database connected!")) .catch((err) => console.error(err)); //... Rest of the code Creating database schemas and models: Let's create the models now. Create a folder models. Inside models, create user.js, chat.js, message.js to create schemas for user details, chat details and message and their respective models. Firstly install validator package. Validator package provides many functions to validate different types of data, such as URLs,emails,, dates, and mobile phone numbers, among others. You can also use it to sanitize data. npm install validator Now put the following code in models/user.js: Copy Code Copied ✔ import mongoose from "mongoose"; import validator from "validator"; const userSchema = new mongoose.Schema({ name: { type: String, required: [true, "Please Provide a Username"], trim: true, minlength: 4, }, email: { type: String, required: [true, "Please provide an email"], unique: true, trim: true, validate: { validator: validator.isEmail, message: "Please Provide Email", }, }, password: { type: String, required: [true, "Please Provide Password"], minlength: 8, trim: true, }, }); export default mongoose.model("User", userSchema); // In models/chat.js, enter the below code. import mongoose from "mongoose"; const chatSchema = new mongoose.Schema( { chatName: { type: String, trim: true, }, isGroupChat: { type: Boolean, default: false, }, users: [ { type: mongoose.Types.ObjectId, ref: "User", }, ], latestMessage: { type: mongoose.Types.ObjectId, ref: "Message", }, groupAdmin: { type: mongoose.Types.ObjectId, ref: "User", }, }, { timestamps: true } ); export default mongoose.model("Chat", chatSchema); // Finally for the message model in models/message.js, the following code will be used import mongoose from "mongoose"; const messageSchema = new mongoose.Schema( { sender: { type: mongoose.Types.ObjectId, ref: "User", }, message: { type: String, trim: true, }, chat: { type: mongoose.Types.ObjectId, ref: "Chat", }, }, { timestamps: true, } ); export default mongoose.model("Message", messageSchema); Creating the controllers: Create a folder named controllers in backend. This folder will contain three files: auth.js: this file has the code for login,register and search functions. chat.js : this file has the code for various functions pertaining to chats, group chats etc. message.js: This file has the code for message related functions like sending a message and getting all messages Put the following code in controllers/auth.js. We are also including the code for creating a jwt. Copy Code Copied ✔ import jwt from "jsonwebtoken"; import User from "../models/user.js"; import bcrypt from "bcryptjs"; const register = async (req, res) => { const { name, email, password } = req.body; if (!name || !email || !password) { return res.status(404).json({ error: "Enter all the values" }); } const isUserExists = await User.findOne({ email: email }); if (isUserExists) { return res .status(404) .json({ error: "User with this email already exists" }); } const hashPassword = await bcrypt.hash(password, 10); const user = await User.create({ name, email, password: hashPassword, }); const token = jwt.sign( { id: user._id, }, process.env.JWT_SECRET, { expiresIn: process.env.JWT_LIFETIME, } ); res.status(201).json({ _id: user._id, name: user.name, email: user.email, token, }); }; const login = async (req, res) => { const { email, password } = req.body; if (!email || !password) { return res.status(400).json({ error: "Please Provide All the Values" }); } const isUser = await User.findOne({ email: email }); if (!isUser) { return res.status(400).json({ error: "Invalid credentials" }); } const comparePassword = await bcrypt.compare(password, isUser.password); if (!comparePassword) { return res.status(400).json({ error: "Invalid credentials" }); } const token = jwt.sign( { id: isUser._id, }, process.env.JWT_SECRET, { expiresIn: process.env.JWT_LIFETIME, } ); res.status(200).json({ success: true, _id: isUser._id, name: isUser.name, email: isUser.email, token, }); }; const searchUser = async (req, res) => { const { search } = req.query; const user = await User.find({ name: { $regex: search, $options: "i" }, }).select("name _id email"); res.status(200).json(user); }; export { register, login, searchUser }; Add the details like JWT_SECRET and JWT_LIFETIME in the .env file. JWT_SECRET is a secret message which can be a string used for encryption and JWT_LIFETIME denotes the time for which jwt is valid. It can have values like 30m,10d etc for 30 minutes, 10 days. JWT_SECRET= somesecretmessage JWT_LIFETIME=40m Enter the following code in the controllers/chat.js file: Copy Code Copied ✔ import Chat from "../models/chat.js"; import User from "../models/user.js"; const getChat = async (req, res) => { const { userId } = req.body; if (!userId) { return res.send("No User Exists!"); } let chat = await Chat.find({ isGroupChat: false, $and: [ { users: { $elemMatch: { $eq: req.user.id } } }, { users: { $elemMatch: { $eq: userId } } }, ], }) .populate("users", "-password") .populate("latestMessage"); chat = await User.populate(chat, { path: "latestMessage.sender", select: "name email _id", }); if (chat.length > 0) { res.send(chat[0]); } else { const createChat = await Chat.create({ chatName: "sender", isGroupChat: false, users: [req.user._id, userId], }); const fullChat = await Chat.findOne({ _id: createChat._id }).populate( "users", "-password" ); res.status(201).json(fullChat); } }; const getChats = async (req, res) => { const chat = await Chat.find({ users: { $elemMatch: { $eq: req.user.id } } }) .populate("users", "-password") .populate("groupAdmin", "-password") .populate("latestMessage") .sort({ updatedAt: -1 }); const user = await User.populate(chat, { path: "latestMessage.sender", select: "name email _id", }); res.status(201).json(user); }; const createGroup = async (req, res) => { if (!req.body.users || !req.body.name) { return res.status(400).send({ message: "Please Fill all the fields" }); } var users = JSON.parse(req.body.users); if (users.length { const { chatId, chatName } = req.body; const updateChat = await Chat.findByIdAndUpdate( chatId, { chatName: chatName, }, { new: true, } ) .populate("users", "-password") .populate("groupAdmin", "-password"); if (!updateChat) { throw new BadRequestError("Chat Not Found"); } else { res.json(updateChat); } }; const addUserToGroup = async (req, res) => { const { chatId, userId } = req.body; const addUser = await Chat.findByIdAndUpdate( chatId, { $push: { users: userId }, }, { new: true, } ) .populate("users", "-password") .populate("groupAdmin", "-password"); if (!addUser) { throw new BadRequestError("Chat Not Found"); } else { res.status(201).json(addUser); } }; const removeFromGroup = async (req, res) => { const { chatId, userId } = req.body; const removeUser = await Chat.findByIdAndUpdate( chatId, { $pull: { users: userId }, }, { new: true, } ) .populate("users", "-password") .populate("groupAdmin", "-password"); if (!removeUser) { throw new BadRequestError("Chat Not Found"); } else { res.status(201).json(removeUser); } }; export { getChat, getChats, createGroup, removeFromGroup, renameGroup, addUserToGroup, }; // Finally add the below code in controllers/message.js import Message from "../models/message.js"; import User from "../models/user.js"; import Chat from "../models/chat.js"; const sendMessage = async (req, res) => { const { message, chatId } = req.body; if (!message || !chatId) { console.log("Invalid data passed into request"); return res .status(400) .json({ error: "Please Provide All Fields To send Message" }); } var newMessage = { sender: req.user._id, message: message, chat: chatId, }; try { let m = await Message.create(newMessage); m = await m.populate("sender", "name"); m = await m.populate("chat"); m = await User.populate(m, { path: "chat.users", select: "name email _id", }); await Chat.findByIdAndUpdate(chatId, { latestMessage: m }, { new: true }); res.status(200).json(m); } catch (error) { res.status(400).json(error.message); } }; const allMessages = async (req, res) => { try { const { chatId } = req.params; const getMessage = await Message.find({ chat: chatId }) .populate("sender", "name email _id") .populate("chat"); res.status(200).json(getMessage); } catch (error) { res.status(400).json(error.message); } }; export { allMessages, sendMessage }; Creating Routes in backend: Now let's create routes in backend for register, login, message and chat. We'll use express router for this. Create a folder named routes in root directory and create 3 files auth.js, chat.js and message.js inside routes. Copy Code Copied ✔ // routes/auth.js will have code something like this import express from "express"; const router = express.Router(); import { register, login, searchUser } from "../controllers/auth.js"; import authenticateUser from "../middleware/auth.js"; router.route("/register").post(register); router.route("/login").post(login); router.route("/users").get(authenticateUser,searchUser); export default router; // routes/chat.js has the following routes import express from "express"; const router = express.Router(); import { getChat, getChats, createGroup, renameGroup, removeFromGroup, addUserToGroup, } from "../controllers/chat.js"; router.route("/").post(getChat).get(getChats); router.route("/createGroup").post(createGroup); router.route("/renameGroup").patch(renameGroup); router.route("/removeFromGroup").patch(removeFromGroup); router.route("/addUserToGroup").patch(addUserToGroup); export default router; // routes/message.js will have this code. import express from "express"; import { allMessages, sendMessage } from "../controllers/message.js"; const router = express.Router(); router.route("/:chatId").get(allMessages); router.route("/").post(sendMessage); export default router; Verifying JWT: Since we are using jwt so will also have to verify the jwt of any user attempting to access the routes. Let’s create a folder named middleware in the parent directory of the project. Inside it, create a file named auth.js. Put the below code inside it. Copy Code Copied ✔ import jwt from "jsonwebtoken"; import User from "../models/user.js"; const auth = async (req, res, next) => { const authHeader = req.headers.authorization; if (!authHeader || !authHeader.startsWith("Bearer")) { return res.status(401).send("Authentication Invalid 1"); } let token = authHeader.split(" ")[1]; try { const payload = jwt.verify(token, process.env.JWT_SECRET); req.user = await User.findById(payload.id).select("-password"); next(); } catch (error) { return res.status(401).send("Authentication Invalid 2"); // throw new Error("Authentication Invalid"); } }; export default auth; // Now let’s import all the necessary files in index.js of backend. import express from "express"; import dotenv from "dotenv"; const app = express(); import mongoose from "mongoose"; import { createServer } from "http"; import cors from "cors"; import { Server } from "socket.io"; const server = createServer(app); import authRoute from "./routes/auth.js"; import chatRoute from "./routes/chat.js"; import messageRoute from "./routes/message.js"; import authenticateUser from "./middleware/auth.js"; dotenv.config(); const PORT = process.env.PORT || 4000; app.use(cors()); app.use(express.urlencoded({ extended: true })); app.use(express.json()); mongoose .connect(process.env.MONGODB_URI, { useNewUrlParser: true, useUnifiedTopology: true, }) .then(() => console.log("Database connected!")) .catch((err) => console.error(err)); app.get("/", (req, res) => { res.send("Hey!! This is a sign that the server is running"); }); app.use("/auth", authRoute); app.use("/chat", authenticateUser, chatRoute); app.use("/message", authenticateUser, messageRoute); server.listen(PORT, () => console.log("Server is running on port", PORT)); Completing the frontend: Let’s go back to frontend to create the necessary components. ChatContainer.js is the main chat window where messages will be visible and it has the following code: Copy Code Copied ✔ import {React,useContext} from "react"; import SingleChat from "./SingleChat"; import { AuthContext } from "../context/context"; const ChatContainer = ({ fetchAgain, setFetchAgain }) => { const { selectedChat } = useContext(AuthContext); return ( ); }; export default ChatContainer; // We forgot to create the javascript file to get some necessary details like sender’s name etc. create a folder named config inside src. Create a file chat.js inside it and put the following code: export const getSender = (loggedUser, users) => { return users[0]._id === loggedUser._id ? users[1].name : users[0].name; }; export const getSenderFull = (loggedUser, users) => { return users[0]._id === loggedUser._id ? users[1] : users[0]; }; export const isSameSenderMargin = (messages, m, i, userId) => { if ( i { return ( i { return ( i === messages.length - 1 && messages[messages.length - 1].sender._id !== userId && messages[messages.length - 1].sender._id ); }; export const isSameUser = (messages, m, i) => { return i > 0 && messages[i - 1].sender._id === m.sender._id; }; Displaying list of chats: The MyChats.js file has the list of all chats of a user. Put the following code in it. Copy Code Copied ✔ import React, { useState, useEffect, useContext } from "react"; import { AuthContext } from "../context/context"; import axios from "axios"; import GroupChatModal from "./GroupChatModal"; import { getSender } from "../config/chat"; import { toast } from "react-toastify"; const MyChats = ({ fetchAgain }) => { const [loggedUser, setLoggedUser] = useState(); const { user, chats, setChats, selectedChat, setSelectedChat } = useContext(AuthContext); const fetchChats = async () => { try { console.log("Fetch chats token " + user.token); const { data } = await axios.get(`${process.env.REACT_APP_URL}/chat`, { headers: { Authorization: `Bearer ${user.token}`, }, }); setChats(data); } catch (error) { toast.error(error); } }; useEffect(() => { setLoggedUser(JSON.parse(localStorage.getItem("user"))); fetchChats(); // eslint-disable-next-line }, [fetchAgain]); return ( My Chats New Group Chat {chats ?

Finishing the Backend: Congrats. We have completed the frontend for our chat app. Let’s complete the backend code also. We’ll firstly import Server from socket.io, then add it to cors, and finally establish the connection with frontend. Then we’ll handle all the aspects of chatting using socket.io. Open index.js and add the code for socket.io and various events related to it. Copy Code Copied ✔ import express from "express"; import dotenv from "dotenv"; const app = express(); import mongoose from "mongoose"; import { createServer } from "http"; import cors from "cors"; import { Server } from "socket.io"; const server = createServer(app); import authRoute from "./routes/auth.js"; import chatRoute from "./routes/chat.js"; import messageRoute from "./routes/message.js"; import authenticateUser from "./middleware/auth.js"; dotenv.config(); const PORT = process.env.PORT || 4000; app.use(cors()); app.use(express.urlencoded({ extended: true })); app.use(express.json()); mongoose .connect(process.env.MONGODB_URI, { useNewUrlParser: true, useUnifiedTopology: true, }) .then(() => console.log("Database connected!")) .catch((err) => console.error(err)); app.get("/", (req, res) => { res.send("Hey!!

The benefits of using SuprSend for push notifications in chat apps are numerous. Here are a few key advantages: Real-time Communication : SuprSend enables instant delivery of push notifications, allowing users to stay connected and engaged with their chat conversations in real-time. Increased User Engagement: By leveraging push notifications, you can keep users informed about new messages, mentions, or important updates, encouraging them to actively participate in conversations. Personalized Experiences: SuprSend offers the ability to segment users and send personalized notifications, ensuring that users receive relevant and tailored messages based on their preferences and behaviors. Retention and Re-engagement: Push notifications serve as a powerful tool to re-engage users and bring them back to your chat app. You can remind users about ongoing conversations, invite them to join groups, or notify them about new features, fostering app retention. Seamless Integration: SuprSend provides easy-to-use APIs and SDKs that seamlessly integrate with popular chat app frameworks, making it effortless to incorporate push notifications into your existing infrastructure. For this chat app, we can implement web push notifications. For this, we can use the Suprsend Client javascript SDK. NOTE: Make sure your website uses https protocol. Creating a template: Create a template for web push notifications on suprsend platform. Creating a workflow: After the template, create a workflow on the suprsend platform. The Event Name will be needed for sending notifications in the code. Suprsend SDK Installation: Install Suprsend Javascript SDK in the client. npm i @suprsend/web-sdk Service worker: Add service worker file in your client. Create a file named serviceworker.js inside public folder(it has to be publicly accessible) and put the following content inside it: importScripts("https://cdn.jsdelivr.net/npm/@suprsend/web-sdk@0.1.30/serviceworker/serviceworker.min.js");init_workspace(WORKSPACE_KEY); Initializing the SDK: Initialize the Suprsend SDK. Make sure to initialize it before calling other methods of it. Since we are using create-react-app, initialize it on top of App class in App.js. For initializing SDK, you need WORKSPACE KEY and WORKSPACE SECRET and VAPID KEY. SuprSend creates a Vapid key when your account is created. You can find this key on the Vendors page on SuprSend dashboard . Go to Vendors > Web Push > VAPID Keys page, copy the public VAPID key and paste it here in vapid key object value Replace WORKSPACE_KEY and WORKSPACE_SECRET with your workspace values. You will get both the tokens from the Suprsend dashboard ( Settings page -> "API keys" section). import suprsend from "@suprsend/web-sdk"; suprsend.init(WORKSPACE KEY, WORKSPACE SECRET, {vapid_key: }) Registering for Web Push notifications: Register for webpush notifications. Suprsend SDK provides method to register service worker which enables your website to prompt notification permission to your users, if not enabled already. suprsend.web_push.register_push(); Check for permission: You can check if the user has granted permission to show push notifications using the below method suprsend.web_push.notification_permission(); This will return a string representing the current permission. The value can be: granted : The user has granted permission for the current origin to display notifications. denied : The user has denied permission for the current origin to display notifications. default : The user's decision is unknown. This will be permission when user first lands on website. Create/Identify a new user You can identify a user using suprsend.identify() method. Call this method as soon as you know the identity of user, that is after login authentication. suprsend.identify(unique_id); Sending Events to SuprSend: Once the workflow is configured, you can pass the Event Name (NEW_MSG in our case) defined in workflow configuration from the SDK and the related workflow will be triggered.

(" 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.

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 .

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.

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.

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 .

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.

https://wiki.python.org/moin/TimeComplexity | TimeComplexity - Python Wiki Search: TimeComplexity TimeComplexity FrontPage RecentChanges FindPage HelpContents TimeComplexity Page Immutable Page Comments Info Attachments More Actions: Raw Text Print View Delete Cache ------------------------ Check Spelling Like Pages Local Site Map ------------------------ Rename Page Delete Page ------------------------ ------------------------ Remove Spam Revert to this revision ------------------------ SlideShow User Login This page documents the time-complexity (aka "Big O" or "Big Oh") of various operations in current CPython. Other Python implementations (or older or still-under development versions of CPython) may have slightly different performance characteristics. However, it is generally safe to assume that they are not slower by more than a factor of O(log n). Generally, 'n' is the number of elements currently in the container. 'k' is either the value of a parameter or the number of elements in the parameter. list The Average Case assumes parameters generated uniformly at random. Internally, a list is represented as an array; the largest costs come from growing beyond the current allocation size (because everything must move), or from inserting or deleting somewhere near the beginning (because everything after that must move). If you need to add/remove at both ends, consider using a collections.deque instead. Operation Average Case Amortized Worst Case Copy O(n) O(n) Append[1] O(1) O(1) Pop last O(1) O(1) Pop intermediate[2] O(n) O(n) Insert O(n) O(n) Get Item O(1) O(1) Set Item O(1) O(1) Delete Item O(n) O(n) Iteration O(n) O(n) Get Slice O(k) O(k) Del Slice O(n) O(n) Set Slice O(k+n) O(k+n) Extend[1] O(k) O(k) Sort O(n log n) O(n log n) Multiply O(nk) O(nk) x in s O(n) min(s), max(s) O(n) Get Length O(1) O(1) collections.deque A deque (double-ended queue) is represented internally as a doubly linked list. (Well, a list of arrays rather than objects, for greater efficiency.) Both ends are accessible, but even looking at the middle is slow, and adding to or removing from the middle is slower still. Operation Average Case Amortized Worst Case Copy O(n) O(n) append O(1) O(1) appendleft O(1) O(1) pop O(1) O(1) popleft O(1) O(1) extend O(k) O(k) extendleft O(k) O(k) rotate O(k) O(k) remove O(n) O(n) Get Length O(1) O(1) set See dict -- the implementation is intentionally very similar. Operation Average case Worst Case notes x in s O(1) O(n) Union s|t O(len(s)+len(t)) Intersection s&t O(min(len(s), len(t))) O(len(s) * len(t)) replace "min" with "max" if t is not a set Multiple intersection s1&s2&..&sn (n-1)*O(l) where l is max(len(s1),..,len(sn)) Difference s-t O(len(s)) s.difference_update(t) O(len(t)) Symmetric Difference s^t O(len(s)) O(len(s) * len(t)) s.symmetric_difference_update(t) O(len(t)) O(len(t) * len(s)) As seen in the source code the complexities for set difference s-t or s.difference(t) ( set_difference() ) and in-place set difference s.difference_update(t) ( set_difference_update_internal() ) are different! The first one is O(len(s)) (for every element in s add it to the new set, if not in t). The second one is O(len(t)) (for every element in t remove it from s). So care must be taken as to which is preferred, depending on which one is the longest set and whether a new set is needed. To perform set operations like s-t, both s and t need to be sets. However you can do the method equivalents even if t is any iterable, for example s.difference(l), where l is a list. dict The Average Case times listed for dict objects assume that the hash function for the objects is sufficiently robust to make collisions uncommon. The Average Case assumes the keys used in parameters are selected uniformly at random from the set of all keys. Note that there is a fast-path for dicts that (in practice) only deal with str keys; this doesn't affect the algorithmic complexity, but it can significantly affect the constant factors: how quickly a typical program finishes. Operation Average Case Amortized Worst Case k in d O(1) O(n) Copy[3] O(n) O(n) Get Item O(1) O(n) Set Item[1] O(1) O(n) Delete Item O(1) O(n) Iteration[3] O(n) O(n) Notes [1] = These operations rely on the "Amortized" part of "Amortized Worst Case". Individual actions may take surprisingly long, depending on the history of the container. [2] = Popping the intermediate element at index k from a list of size n shifts all elements after k by one slot to the left using memmove. n - k elements have to be moved, so the operation is O(n - k) . The best case is popping the second to last element, which necessitates one move, the worst case is popping the first element, which involves n - 1 moves. The average case for an average value of k is popping the element the middle of the list, which takes O(n/2) = O(n) operations. [3] = For these operations, the worst case n is the maximum size the container ever achieved, rather than just the current size. For example, if N objects are added to a dictionary, then N-1 are deleted, the dictionary will still be sized for N objects (at least) until another insertion is made.

A ChainMap class is provided for quickly linking a number of mappings so they can be treated as a single unit. It is often much faster than creating a new dictionary and running multiple update() calls. The class can be used to simulate nested scopes and is useful in templating. class collections. ChainMap ( * maps ) ¶ A ChainMap groups multiple dicts or other mappings together to create a single, updateable view. If no maps are specified, a single empty dictionary is provided so that a new chain always has at least one mapping. The underlying mappings are stored in a list. That list is public and can be accessed or updated using the maps attribute. There is no other state. Lookups search the underlying mappings successively until a key is found. In contrast, writes, updates, and deletions only operate on the first mapping. A ChainMap incorporates the underlying mappings by reference. So, if one of the underlying mappings gets updated, those changes will be reflected in ChainMap . All of the usual dictionary methods are supported. In addition, there is a maps attribute, a method for creating new subcontexts, and a property for accessing all but the first mapping: maps ¶ A user updateable list of mappings. The list is ordered from first-searched to last-searched. It is the only stored state and can be modified to change which mappings are searched. The list should always contain at least one mapping. new_child ( m = None , ** kwargs ) ¶ Returns a new ChainMap containing a new map followed by all of the maps in the current instance. If m is specified, it becomes the new map at the front of the list of mappings; if not specified, an empty dict is used, so that a call to d.new_child() is equivalent to: ChainMap({}, *d.maps) . If any keyword arguments are specified, they update passed map or new empty dict. This method is used for creating subcontexts that can be updated without altering values in any of the parent mappings. Changed in version 3.4: The optional m parameter was added. Changed in version 3.10: Keyword arguments support was added. parents ¶ Property returning a new ChainMap containing all of the maps in the current instance except the first one. This is useful for skipping the first map in the search. Use cases are similar to those for the nonlocal keyword used in nested scopes . The use cases also parallel those for the built-in super() function. A reference to d.parents is equivalent to: ChainMap(*d.maps[1:]) . Note, the iteration order of a ChainMap is determined by scanning the mappings last to first: >>> baseline = { 'music' : 'bach' , 'art' : 'rembrandt' } >>> adjustments = { 'art' : 'van gogh' , 'opera' : 'carmen' } >>> list ( ChainMap ( adjustments , baseline )) ['music', 'art', 'opera'] This gives the same ordering as a series of dict.update() calls starting with the last mapping: >>> combined = baseline . copy () >>> combined . update ( adjustments ) >>> list ( combined ) ['music', 'art', 'opera'] Changed in version 3.9: Added support for | and |= operators, specified in PEP 584 . See also The MultiContext class in the Enthought CodeTools package has options to support writing to any mapping in the chain. Django’s Context class for templating is a read-only chain of mappings. It also features pushing and popping of contexts similar to the new_child() method and the parents property. The Nested Contexts recipe has options to control whether writes and other mutations apply only to the first mapping or to any mapping in the chain. A greatly simplified read-only version of Chainmap . ChainMap Examples and Recipes ¶ This section shows various approaches to working with chained maps. Example of simulating Python’s internal lookup chain: import builtins pylookup = ChainMap ( locals (), globals (), vars ( builtins )) Example of letting user specified command-line arguments take precedence over environment variables which in turn take precedence over default values: import os , argparse defaults = { 'color' : 'red' , 'user' : 'guest' } parser = argparse . ArgumentParser () parser . add_argument ( '-u' , '--user' ) parser . add_argument ( '-c' , '--color' ) namespace = parser . parse_args () command_line_args = { k : v for k , v in vars ( namespace ) . items () if v is not None } combined = ChainMap ( command_line_args , os . environ , defaults ) print ( combined [ 'color' ]) print ( combined [ 'user' ]) Example patterns for using the ChainMap class to simulate nested contexts: c = ChainMap () # Create root context d = c . new_child () # Create nested child context e = c . new_child () # Child of c, independent from d e . maps [ 0 ] # Current context dictionary -- like Python's locals() e . maps [ - 1 ] # Root context -- like Python's globals() e . parents # Enclosing context chain -- like Python's nonlocals d [ 'x' ] = 1 # Set value in current context d [ 'x' ] # Get first key in the chain of contexts del d [ 'x' ] # Delete from current context list ( d ) # All nested values k in d # Check all nested values len ( d ) # Number of nested values d . items () # All nested items dict ( d ) # Flatten into a regular dictionary The ChainMap class only makes updates (writes and deletions) to the first mapping in the chain while lookups will search the full chain. However, if deep writes and deletions are desired, it is easy to make a subclass that updates keys found deeper in the chain: class DeepChainMap ( ChainMap ): 'Variant of ChainMap that allows direct updates to inner scopes' def __setitem__ ( self , key , value ): for mapping in self . maps : if key in mapping : mapping [ key ] = value return self . maps [ 0 ][ key ] = value def __delitem__ ( self , key ): for mapping in self . maps : if key in mapping : del mapping [ key ] return raise KeyError ( key ) >>> d = DeepChainMap ({ 'zebra' : 'black' }, { 'elephant' : 'blue' }, { 'lion' : 'yellow' }) >>> d [ 'lion' ] = 'orange' # update an existing key two levels down >>> d [ 'snake' ] = 'red' # new keys get added to the topmost dict >>> del d [ 'elephant' ] # remove an existing key one level down >>> d # display result DeepChainMap ({ 'zebra' : 'black' , 'snake' : 'red' }, {}, { 'lion' : 'orange' }) Counter objects ¶ A counter tool is provided to support convenient and rapid tallies. For example: >>> # Tally occurrences of words in a list >>> cnt = Counter () >>> for word in [ 'red' , 'blue' , 'red' , 'green' , 'blue' , 'blue' ]: ... cnt [ word ] += 1 ... >>> cnt Counter({'blue': 3, 'red': 2, 'green': 1}) >>> # Find the ten most common words in Hamlet >>> import re >>> words = re . findall ( r '\w+' , open ( 'hamlet.txt' ) . read () . lower ()) >>> Counter ( words ) . most_common ( 10 ) [('the', 1143), ('and', 966), ('to', 762), ('of', 669), ('i', 631), ('you', 554), ('a', 546), ('my', 514), ('hamlet', 471), ('in', 451)] class collections. Counter ( [ iterable-or-mapping ] ) ¶ A Counter is a dict subclass for counting hashable objects. It is a collection where elements are stored as dictionary keys and their counts are stored as dictionary values. Counts are allowed to be any integer value including zero or negative counts. The Counter class is similar to bags or multisets in other languages. Elements are counted from an iterable or initialized from another mapping (or counter): >>> c = Counter () # a new, empty counter >>> c = Counter ( 'gallahad' ) # a new counter from an iterable >>> c = Counter ({ 'red' : 4 , 'blue' : 2 }) # a new counter from a mapping >>> c = Counter ( cats = 4 , dogs = 8 ) # a new counter from keyword args Counter objects have a dictionary interface except that they return a zero count for missing items instead of raising a KeyError : >>> c = Counter ([ 'eggs' , 'ham' ]) >>> c [ 'bacon' ] # count of a missing element is zero 0 Setting a count to zero does not remove an element from a counter. Use del to remove it entirely: >>> c [ 'sausage' ] = 0 # counter entry with a zero count >>> del c [ 'sausage' ] # del actually removes the entry Added in version 3.1. Changed in version 3.7: As a dict subclass, Counter inherited the capability to remember insertion order. Math operations on Counter objects also preserve order. Results are ordered according to when an element is first encountered in the left operand and then by the order encountered in the right operand. Counter objects support additional methods beyond those available for all dictionaries: elements ( ) ¶ Return an iterator over elements repeating each as many times as its count. Elements are returned in the order first encountered. If an element’s count is less than one, elements() will ignore it. >>> c = Counter ( a = 4 , b = 2 , c = 0 , d =- 2 ) >>> sorted ( c . elements ()) ['a', 'a', 'a', 'a', 'b', 'b'] most_common ( [ n ] ) ¶ Return a list of the n most common elements and their counts from the most common to the least. If n is omitted or None , most_common() returns all elements in the counter. Elements with equal counts are ordered in the order first encountered: >>> Counter ( 'abracadabra' ) . most_common ( 3 ) [('a', 5), ('b', 2), ('r', 2)] subtract ( [ iterable-or-mapping ] ) ¶ Elements are subtracted from an iterable or from another mapping (or counter). Like dict.update() but subtracts counts instead of replacing them. Both inputs and outputs may be zero or negative. >>> c = Counter ( a = 4 , b = 2 , c = 0 , d =- 2 ) >>> d = Counter ( a = 1 , b = 2 , c = 3 , d = 4 ) >>> c . subtract ( d ) >>> c Counter({'a': 3, 'b': 0, 'c': -3, 'd': -6}) Added in version 3.2. total ( ) ¶ Compute the sum of the counts. >>> c = Counter ( a = 10 , b = 5 , c = 0 ) >>> c . total () 15 Added in version 3.10. The usual dictionary methods are available for Counter objects except for two which work differently for counters. fromkeys ( iterable ) ¶ This class method is not implemented for Counter objects. update ( [ iterable-or-mapping ] ) ¶ Elements are counted from an iterable or added-in from another mapping (or counter). Like dict.update() but adds counts instead of replacing them. Also, the iterable is expected to be a sequence of elements, not a sequence of (key, value) pairs. Counters support rich comparison operators for equality, subset, and superset relationships: == , != , < , <= , > , >= . All of those tests treat missing elements as having zero counts so that Counter(a=1) == Counter(a=1, b=0) returns true. Changed in version 3.10: Rich comparison operations were added. Changed in version 3.10: In equality tests, missing elements are treated as having zero counts. Formerly, Counter(a=3) and Counter(a=3, b=0) were considered distinct. Common patterns for working with Counter objects: c . total () # total of all counts c . clear () # reset all counts list ( c ) # list unique elements set ( c ) # convert to a set dict ( c ) # convert to a regular dictionary c . items () # access the (elem, cnt) pairs Counter ( dict ( list_of_pairs )) # convert from a list of (elem, cnt) pairs c . most_common ()[: - n - 1 : - 1 ] # n least common elements + c # remove zero and negative counts Several mathematical operations are provided for combining Counter objects to produce multisets (counters that have counts greater than zero). Addition and subtraction combine counters by adding or subtracting the counts of corresponding elements. Intersection and union return the minimum and maximum of corresponding counts. Equality and inclusion compare corresponding counts. Each operation can accept inputs with signed counts, but the output will exclude results with counts of zero or less. >>> c = Counter ( a = 3 , b = 1 ) >>> d = Counter ( a = 1 , b = 2 ) >>> c + d # add two counters together: c[x] + d[x] Counter({'a': 4, 'b': 3}) >>> c - d # subtract (keeping only positive counts) Counter({'a': 2}) >>> c & d # intersection: min(c[x], d[x]) Counter({'a': 1, 'b': 1}) >>> c | d # union: max(c[x], d[x]) Counter({'a': 3, 'b': 2}) >>> c == d # equality: c[x] == d[x] False >>> c <= d # inclusion: c[x] <= d[x] False Unary addition and subtraction are shortcuts for adding an empty counter or subtracting from an empty counter. >>> c = Counter ( a = 2 , b =- 4 ) >>> + c Counter({'a': 2}) >>> - c Counter({'b': 4}) Added in version 3.3: Added support for unary plus, unary minus, and in-place multiset operations. Note Counters were primarily designed to work with positive integers to represent running counts; however, care was taken to not unnecessarily preclude use cases needing other types or negative values. To help with those use cases, this section documents the minimum range and type restrictions. The Counter class itself is a dictionary subclass with no restrictions on its keys and values. The values are intended to be numbers representing counts, but you could store anything in the value field. The most_common() method requires only that the values be orderable. For in-place operations such as c[key] += 1 , the value type need only support addition and subtraction. So fractions, floats, and decimals would work and negative values are supported. The same is also true for update() and subtract() which allow negative and zero values for both inputs and outputs. The multiset methods are designed only for use cases with positive values. The inputs may be negative or zero, but only outputs with positive values are created. There are no type restrictions, but the value type needs to support addition, subtraction, and comparison. The elements() method requires integer counts. It ignores zero and negative counts. See also Bag class in Smalltalk. Wikipedia entry for Multisets . C++ multisets tutorial with examples. For mathematical operations on multisets and their use cases, see Knuth, Donald. The Art of Computer Programming Volume II, Section 4.6.3, Exercise 19 . To enumerate all distinct multisets of a given size over a given set of elements, see itertools.combinations_with_replacement() : map ( Counter , combinations_with_replacement ( 'ABC' , 2 )) # --> AA AB AC BB BC CC deque objects ¶ class collections. deque ( [ iterable [ , maxlen ] ] ) ¶ Returns a new deque object initialized left-to-right (using append() ) with data from iterable . If iterable is not specified, the new deque is empty. Deques are a generalization of stacks and queues (the name is pronounced “deck” and is short for “double-ended queue”). Deques support thread-safe, memory efficient appends and pops from either side of the deque with approximately the same O (1) performance in either direction. Though list objects support similar operations, they are optimized for fast fixed-length operations and incur O ( n ) memory movement costs for pop(0) and insert(0, v) operations which change both the size and position of the underlying data representation. If maxlen is not specified or is None , deques may grow to an arbitrary length. Otherwise, the deque is bounded to the specified maximum length. Once a bounded length deque is full, when new items are added, a corresponding number of items are discarded from the opposite end. Bounded length deques provide functionality similar to the tail filter in Unix. They are also useful for tracking transactions and other pools of data where only the most recent activity is of interest. Deque objects support the following methods: append ( x ) ¶ Add x to the right side of the deque. appendleft ( x ) ¶ Add x to the left side of the deque. clear ( ) ¶ Remove all elements from the deque leaving it with length 0. copy ( ) ¶ Create a shallow copy of the deque. Added in version 3.5. count ( x ) ¶ Count the number of deque elements equal to x . Added in version 3.2. extend ( iterable ) ¶ Extend the right side of the deque by appending elements from the iterable argument. extendleft ( iterable ) ¶ Extend the left side of the deque by appending elements from iterable . Note, the series of left appends results in reversing the order of elements in the iterable argument. index ( x [ , start [ , stop ] ] ) ¶ Return the position of x in the deque (at or after index start and before index stop ). Returns the first match or raises ValueError if not found. Added in version 3.5. insert ( i , x ) ¶ Insert x into the deque at position i . If the insertion would cause a bounded deque to grow beyond maxlen , an IndexError is raised. Added in version 3.5. pop ( ) ¶ Remove and return an element from the right side of the deque. If no elements are present, raises an IndexError . popleft ( ) ¶ Remove and return an element from the left side of the deque. If no elements are present, raises an IndexError . remove ( value ) ¶ Remove the first occurrence of value . If not found, raises a ValueError . reverse ( ) ¶ Reverse the elements of the deque in-place and then return None . Added in version 3.2. rotate ( n = 1 ) ¶ Rotate the deque n steps to the right. If n is negative, rotate to the left. When the deque is not empty, rotating one step to the right is equivalent to d.appendleft(d.pop()) , and rotating one step to the left is equivalent to d.append(d.popleft()) . Deque objects also provide one read-only attribute: maxlen ¶ Maximum size of a deque or None if unbounded. Added in version 3.1. In addition to the above, deques support iteration, pickling, len(d) , reversed(d) , copy.copy(d) , copy.deepcopy(d) , membership testing with the in operator, and subscript references such as d[0] to access the first element. Indexed access is O (1) at both ends but slows to O ( n ) in the middle. For fast random access, use lists instead. Starting in version 3.5, deques support __add__() , __mul__() , and __imul__() . Example: >>> from collections import deque >>> d = deque ( 'ghi' ) # make a new deque with three items >>> for elem in d : # iterate over the deque's elements ... print ( elem . upper ()) G H I >>> d . append ( 'j' ) # add a new entry to the right side >>> d . appendleft ( 'f' ) # add a new entry to the left side >>> d # show the representation of the deque deque(['f', 'g', 'h', 'i', 'j']) >>> d . pop () # return and remove the rightmost item 'j' >>> d . popleft () # return and remove the leftmost item 'f' >>> list ( d ) # list the contents of the deque ['g', 'h', 'i'] >>> d [ 0 ] # peek at leftmost item 'g' >>> d [ - 1 ] # peek at rightmost item 'i' >>> list ( reversed ( d )) # list the contents of a deque in reverse ['i', 'h', 'g'] >>> 'h' in d # search the deque True >>> d . extend ( 'jkl' ) # add multiple elements at once >>> d deque(['g', 'h', 'i', 'j', 'k', 'l']) >>> d . rotate ( 1 ) # right rotation >>> d deque(['l', 'g', 'h', 'i', 'j', 'k']) >>> d . rotate ( - 1 ) # left rotation >>> d deque(['g', 'h', 'i', 'j', 'k', 'l']) >>> deque ( reversed ( d )) # make a new deque in reverse order deque(['l', 'k', 'j', 'i', 'h', 'g']) >>> d . clear () # empty the deque >>> d . pop () # cannot pop from an empty deque Traceback (most recent call last): File "<pyshell#6>" , line 1 , in - toplevel - d . pop () IndexError : pop from an empty deque >>> d . extendleft ( 'abc' ) # extendleft() reverses the input order >>> d deque(['c', 'b', 'a']) deque Recipes ¶ This section shows various approaches to working with deques. Bounded length deques provide functionality similar to the tail filter in Unix: def tail ( filename , n = 10 ): 'Return the last n lines of a file' with open ( filename ) as f : return deque ( f , n ) Another approach to using deques is to maintain a sequence of recently added elements by appending to the right and popping to the left: def moving_average ( iterable , n = 3 ): # moving_average([40, 30, 50, 46, 39, 44]) --> 40.0 42.0 45.0 43.0 # https://en.wikipedia.org/wiki/Moving_average it = iter ( iterable ) d = deque ( itertools . islice ( it , n - 1 )) d . appendleft ( 0 ) s = sum ( d ) for elem in it : s += elem - d . popleft () d . append ( elem ) yield s / n A round-robin scheduler can be implemented with input iterators stored in a deque . Values are yielded from the active iterator in position zero. If that iterator is exhausted, it can be removed with popleft() ; otherwise, it can be cycled back to the end with the rotate() method: def roundrobin ( * iterables ): "roundrobin('ABC', 'D', 'EF') --> A D E B F C" iterators = deque ( map ( iter , iterables )) while iterators : try : while True : yield next ( iterators [ 0 ]) iterators . rotate ( - 1 ) except StopIteration : # Remove an exhausted iterator. iterators . popleft () The rotate() method provides a way to implement deque slicing and deletion. For example, a pure Python implementation of del d[n] relies on the rotate() method to position elements to be popped: def delete_nth ( d , n ): d . rotate ( - n ) d . popleft () d . rotate ( n ) To implement deque slicing, use a similar approach applying rotate() to bring a target element to the left side of the deque. Remove old entries with popleft() , add new entries with extend() , and then reverse the rotation. With minor variations on that approach, it is easy to implement Forth style stack manipulations such as dup , drop , swap , over , pick , rot , and roll . defaultdict objects ¶ class collections. defaultdict ( default_factory=None , / [ , ... ] ) ¶ Return a new dictionary-like object. defaultdict is a subclass of the built-in dict class. It overrides one method and adds one writable instance variable. The remaining functionality is the same as for the dict class and is not documented here. The first argument provides the initial value for the default_factory attribute; it defaults to None . All remaining arguments are treated the same as if they were passed to the dict constructor, including keyword arguments. defaultdict objects support the following method in addition to the standard dict operations: __missing__ ( key ) ¶ If the default_factory attribute is None , this raises a KeyError exception with the key as argument. If default_factory is not None , it is called without arguments to provide a default value for the given key , this value is inserted in the dictionary for the key , and returned. If calling default_factory raises an exception this exception is propagated unchanged. This method is called by the __getitem__() method of the dict class when the requested key is not found; whatever it returns or raises is then returned or raised by __getitem__() . Note that __missing__() is not called for any operations besides __getitem__() . This means that get() will, like normal dictionaries, return None as a default rather than using default_factory . defaultdict objects support the following instance variable: default_factory ¶ This attribute is used by the __missing__() method; it is initialized from the first argument to the constructor, if present, or to None , if absent. Changed in version 3.9: Added merge ( | ) and update ( |= ) operators, specified in PEP 584 . defaultdict Examples ¶ Using list as the default_factory , it is easy to group a sequence of key-value pairs into a dictionary of lists: >>> s = [( 'yellow' , 1 ), ( 'blue' , 2 ), ( 'yellow' , 3 ), ( 'blue' , 4 ), ( 'red' , 1 )] >>> d = defaultdict ( list ) >>> for k , v in s : ... d [ k ] . append ( v ) ... >>> sorted ( d . items ()) [('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])] When each key is encountered for the first time, it is not already in the mapping; so an entry is automatically created using the default_factory function which returns an empty list . The list.append() operation then attaches the value to the new list. When keys are encountered again, the look-up proceeds normally (returning the list for that key) and the list.append() operation adds another value to the list. This technique is simpler and faster than an equivalent technique using dict.setdefault() : >>> d = {} >>> for k , v in s : ... d . setdefault ( k , []) . append ( v ) ... >>> sorted ( d . items ()) [('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])] Setting the default_factory to int makes the defaultdict useful for counting (like a bag or multiset in other languages): >>> s = 'mississippi' >>> d = defaultdict ( int ) >>> for k in s : ... d [ k ] += 1 ... >>> sorted ( d . items ()) [('i', 4), ('m', 1), ('p', 2), ('s', 4)] When a letter is first encountered, it is missing from the mapping, so the default_factory function calls int() to supply a default count of zero. The increment operation then builds up the count for each letter. The function int() which always returns zero is just a special case of constant functions. A faster and more flexible way to create constant functions is to use a lambda function which can supply any constant value (not just zero): >>> def constant_factory ( value ): ... return lambda : value ... >>> d = defaultdict ( constant_factory ( '<missing>' )) >>> d . update ( name = 'John' , action = 'ran' ) >>> ' %(name)s %(action)s to %(object)s ' % d 'John ran to <missing>' Setting the default_factory to set makes the defaultdict useful for building a dictionary of sets: >>> s = [( 'red' , 1 ), ( 'blue' , 2 ), ( 'red' , 3 ), ( 'blue' , 4 ), ( 'red' , 1 ), ( 'blue' , 4 )] >>> d = defaultdict ( set ) >>> for k , v in s : ... d [ k ] . add ( v ) ... >>> sorted ( d . items ()) [('blue', {2, 4}), ('red', {1, 3})] namedtuple() Factory Function for Tuples with Named Fields ¶ Named tuples assign meaning to each position in a tuple and allow for more readable, self-documenting code. They can be used wherever regular tuples are used, and they add the ability to access fields by name instead of position index. collections. namedtuple ( typename , field_names , * , rename = False , defaults = None , module = None ) ¶ Returns a new tuple subclass named typename . The new subclass is used to create tuple-like objects that have fields accessible by attribute lookup as well as being indexable and iterable. Instances of the subclass also have a helpful docstring (with typename and field_names ) and a helpful __repr__() method which lists the tuple contents in a name=value format. The field_names are a sequence of strings such as ['x', 'y'] . Alternatively, field_names can be a single string with each fieldname separated by whitespace and/or commas, for example 'x y' or 'x, y' . Any valid Python identifier may be used for a fieldname except for names starting with an underscore. Valid identifiers consist of letters, digits, and underscores but do not start with a digit or underscore and cannot be a keyword such as class , for , return , global , pass , or raise . If rename is true, invalid fieldnames are automatically replaced with positional names. For example, ['abc', 'def', 'ghi', 'abc'] is converted to ['abc', '_1', 'ghi', '_3'] , eliminating the keyword def and the duplicate fieldname abc . defaults can be None or an iterable of default values. Since fields with a default value must come after any fields without a default, the defaults are applied to the rightmost parameters. For example, if the fieldnames are ['x', 'y', 'z'] and the defaults are (1, 2) , then x will be a required argument, y will default to 1 , and z will default to 2 . If module is defined, the __module__ attribute of the named tuple is set to that value. Named tuple instances do not have per-instance dictionaries, so they are lightweight and require no more memory than regular tuples. To support pickling, the named tuple class should be assigned to a variable that matches typename . Changed in version 3.1: Added support for rename . Changed in version 3.6: The verbose and rename parameters became keyword-only arguments . Changed in version 3.6: Added the module parameter. Changed in version 3.7: Removed the verbose parameter and the _source attribute. Changed in version 3.7: Added the defaults parameter and the _field_defaults attribute. >>> # Basic example >>> Point = namedtuple ( 'Point' , [ 'x' , 'y' ]) >>> p = Point ( 11 , y = 22 ) # instantiate with positional or keyword arguments >>> p [ 0 ] + p [ 1 ] # indexable like the plain tuple (11, 22) 33 >>> x , y = p # unpack like a regular tuple >>> x , y (11, 22) >>> p . x + p . y # fields also accessible by name 33 >>> p # readable __repr__ with a name=value style Point(x=11, y=22) Named tuples are especially useful for assigning field names to result tuples returned by the csv or sqlite3 modules: EmployeeRecord = namedtuple ( 'EmployeeRecord' , 'name, age, title, department, paygrade' ) import csv for emp in map ( EmployeeRecord . _make , csv . reader ( open ( "employees.csv" , "rb" ))): print ( emp . name , emp . title ) import sqlite3 conn = sqlite3 . connect ( '/companydata' ) cursor = conn . cursor () cursor . execute ( 'SELECT name, age, title, department, paygrade FROM employees' ) for emp in map ( EmployeeRecord . _make , cursor . fetchall ()): print ( emp . name , emp . title ) In addition to the methods inherited from tuples, named tuples support three additional methods and two attributes. To prevent conflicts with field names, the method and attribute names start with an underscore. classmethod somenamedtuple. _make ( iterable ) ¶ Class method that makes a new instance from an existing sequence or iterable. >>> t = [ 11 , 22 ] >>> Point . _make ( t ) Point(x=11, y=22) somenamedtuple. _asdict ( ) ¶ Return a new dict which maps field names to their corresponding values: >>> p = Point ( x = 11 , y = 22 ) >>> p . _asdict () {'x': 11, 'y': 22} Changed in version 3.1: Returns an OrderedDict instead of a regular dict . Changed in version 3.8: Returns a regular dict instead of an OrderedDict . As of Python 3.7, regular dicts are guaranteed to be ordered. If the extra features of OrderedDict are required, the suggested remediation is to cast the result to the desired type: OrderedDict(nt._asdict()) . somenamedtuple. _replace ( ** kwargs ) ¶ Return a new instance of the named tuple replacing specified fields with new values: >>> p = Point ( x = 11 , y = 22 ) >>> p . _replace ( x = 33 ) Point(x=33, y=22) >>> for partnum , record in inventory . items (): ... inventory [ partnum ] = record . _replace ( price = newprices [ partnum ], timestamp = time . now ()) Named tuples are also supported by generic function copy.replace() . Changed in version 3.13: Raise TypeError instead of ValueError for invalid keyword arguments. somenamedtuple. _fields ¶ Tuple of strings listing the field names. Useful for introspection and for creating new named tuple types from existing named tuples. >>> p . _fields # view the field names ('x', 'y') >>> Color = namedtuple ( 'Color' , 'red green blue' ) >>> Pixel = namedtuple ( 'Pixel' , Point . _fields + Color . _fields ) >>> Pixel ( 11 , 22 , 128 , 255 , 0 ) Pixel(x=11, y=22, red=128, green=255, blue=0) somenamedtuple. _field_defaults ¶ Dictionary mapping field names to default values. >>> Account = namedtuple ( 'Account' , [ 'type' , 'balance' ], defaults = [ 0 ]) >>> Account . _field_defaults {'balance': 0} >>> Account ( 'premium' ) Account(type='premium', balance=0) To retrieve a field whose name is stored in a string, use the getattr() function: >>> getattr ( p , 'x' ) 11 To convert a dictionary to a named tuple, use the double-star-operator (as described in Unpacking Argument Lists ): >>> d = { 'x' : 11 , 'y' : 22 } >>> Point ( ** d ) Point(x=11, y=22) Since a named tuple is a regular Python class, it is easy to add or change functionality with a subclass. Here is how to add a calculated field and a fixed-width print format: >>> class Point ( namedtuple ( 'Point' , [ 'x' , 'y' ])): ... __slots__ = () ... @property ... def hypot ( self ): ... return ( self . x ** 2 + self . y ** 2 ) ** 0.5 ... def __str__ ( self ): ... return 'Point: x= %6.3f y= %6.3f hypot= %6.3f ' % ( self . x , self . y , self . hypot ) >>> for p in Point ( 3 , 4 ), Point ( 14 , 5 / 7 ): ... print ( p ) Point: x= 3.000 y= 4.000 hypot= 5.000 Point: x=14.000 y= 0.714 hypot=14.018 The subclass shown above sets __slots__ to an empty tuple. This helps keep memory requirements low by preventing the creation of instance dictionaries. Subclassing is not useful for adding new, stored fields. Instead, simply create a new named tuple type from the _fields attribute: >>> Point3D = namedtuple ( 'Point3D' , Point . _fields + ( 'z' ,)) Docstrings can be customized by making direct assignments to the __doc__ fields: >>> Book = namedtuple ( 'Book' , [ 'id' , 'title' , 'authors' ]) >>> Book . __doc__ += ': Hardcover book in active collection' >>> Book . id . __doc__ = '13-digit ISBN' >>> Book . title . __doc__ = 'Title of first printing' >>> Book . authors . __doc__ = 'List of authors sorted by last name' Changed in version 3.5: Property docstrings became writeable. See also See typing.NamedTuple for a way to add type hints for named tuples. It also provides an elegant notation using the class keyword: class Component ( NamedTuple ): part_number : int weight : float description : Optional [ str ] = None See types.SimpleNamespace() for a mutable namespace based on an underlying dictionary instead of a tuple. The dataclasses module provides a decorator and functions for automatically adding generated special methods to user-defined classes. OrderedDict objects ¶ Ordered dictionaries are just like regular dictionaries but have some extra capabilities relating to ordering operations. They have become less important now that the built-in dict class gained the ability to remember insertion order (this new behavior became guaranteed in Python 3.7). Some differences from dict still remain: The regular dict was designed to be very good at mapping operations. Tracking insertion order was secondary. The OrderedDict was designed to be good at reordering operations. Space efficiency, iteration speed, and the performance of update operations were secondary. The OrderedDict algorithm can handle frequent reordering operations better than dict . As shown in the recipes below, this makes it suitable for implementing various kinds of LRU caches. The equality operation for OrderedDict checks for matching order. A regular dict can emulate the order sensitive equality test with p == q and all(k1 == k2 for k1, k2 in zip(p, q)) . The popitem() method of OrderedDict has a different signature. It accepts an optional argument to specify which item is popped. A regular dict can emulate OrderedDict’s od.popitem(last=True) with d.popitem() which is guaranteed to pop the rightmost (last) item. A regular dict can emulate OrderedDict’s od.popitem(last=False) with (k := next(iter(d)), d.pop(k)) which will return and remove the leftmost (first) item if it exists. OrderedDict has a move_to_end() method to efficiently reposition an element to an endpoint. A regular dict can emulate OrderedDict’s od.move_to_end(k, last=True) with d[k] = d.pop(k) which will move the key and its associated value to the rightmost (last) position. A regular dict does not have an efficient equivalent for OrderedDict’s od.move_to_end(k, last=False) which moves the key and its associated value to the leftmost (first) position. Until Python 3.8, dict lacked a __reversed__() method. class collections. OrderedDict ( [ items ] ) ¶ Return an instance of a dict subclass that has methods specialized for rearranging dictionary order. Added in version 3.1. popitem ( last = True ) ¶ The popitem() method for ordered dictionaries returns and removes a (key, value) pair. The pairs are returned in LIFO order if last is true or FIFO order if false. move_to_end ( key , last = True ) ¶ Move an existing key to either end of an ordered dictionary. The item is moved to the right end if last is true (the default) or to the beginning if last is false. Raises KeyError if the key does not exist: >>> d = OrderedDict . fromkeys ( 'abcde' ) >>> d . move_to_end ( 'b' ) >>> '' . join ( d ) 'acdeb' >>> d . move_to_end ( 'b' , last = False ) >>> '' . join ( d ) 'bacde' Added in version 3.2. In addition to the usual mapping methods, ordered dictionaries also support reverse iteration using reversed() . Equality tests between OrderedDict objects are order-sensitive and are roughly equivalent to list(od1.items())==list(od2.items()) . Equality tests between OrderedDict objects and other Mapping objects are order-insensitive like regular dictionaries. This allows OrderedDict objects to be substituted anywhere a regular dictionary is used. Changed in version 3.5: The items, keys, and values views of OrderedDict now support reverse iteration using reversed() . Changed in version 3.6: With the acceptance of PEP 468 , order is retained for keyword arguments passed to the OrderedDict constructor and its update() method. Changed in version 3.9: Added merge ( | ) and update ( |= ) operators, specified in PEP 584 . OrderedDict Examples and Recipes ¶ It is straightforward to create an ordered dictionary variant that remembers the order the keys were last inserted. If a new entry overwrites an existing entry, the original insertion position is changed and moved to the end: class LastUpdatedOrderedDict ( OrderedDict ): 'Store items in the order the keys were last added' def __setitem__ ( self , key , value ): super () . __setitem__ ( key , value ) self . move_to_end ( key ) An OrderedDict would also be useful for implementing variants of functools.lru_cache() : from collections import OrderedDict from time import time class TimeBoundedLRU : "LRU Cache that invalidates and refreshes old entries." def __init__ ( self , func , maxsize = 128 , maxage = 30 ): self . cache = OrderedDict () # { args : (timestamp, result)} self . func = func self . maxsize = maxsize self . maxage = maxage def __call__ ( self , * args ): if args in self . cache : self . cache . move_to_end ( args ) timestamp , result = self . cache [ args ] if time () - timestamp <= self . maxage : return result result = self . func ( * args ) self . cache [ args ] = time (), result if len ( self . cache ) > self . maxsize : self . cache . popitem ( last = False ) return result class MultiHitLRUCache : """ LRU cache that defers caching a result until it has been requested multiple times.

""" def __init__ ( self , func , maxsize = 128 , maxrequests = 4096 , cache_after = 1 ): self . requests = OrderedDict () # { uncached_key : request_count } self . cache = OrderedDict () # { cached_key : function_result } self . func = func self . maxrequests = maxrequests # max number of uncached requests self . maxsize = maxsize # max number of stored return values self . cache_after = cache_after def __call__ ( self , * args ): if args in self . cache : self . cache . move_to_end ( args ) return self . cache [ args ] result = self . func ( * args ) self . requests [ args ] = self . requests . get ( args , 0 ) + 1 if self . requests [ args ] <= self . cache_after : self . requests . move_to_end ( args ) if len ( self . requests ) > self . maxrequests : self . requests . popitem ( last = False ) else : self . requests . pop ( args , None ) self . cache [ args ] = result if len ( self . cache ) > self . maxsize : self . cache . popitem ( last = False ) return result UserDict objects ¶ The class, UserDict acts as a wrapper around dictionary objects. The need for this class has been partially supplanted by the ability to subclass directly from dict ; however, this class can be easier to work with because the underlying dictionary is accessible as an attribute. class collections. UserDict ( [ initialdata ] ) ¶ Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it to be used for other purposes. In addition to supporting the methods and operations of mappings, UserDict instances provide the following attribute: data ¶ A real dictionary used to store the contents of the UserDict class. UserList objects ¶ This class acts as a wrapper around list objects. It is a useful base class for your own list-like classes which can inherit from them and override existing methods or add new ones. In this way, one can add new behaviors to lists. The need for this class has been partially supplanted by the ability to subclass directly from list ; however, this class can be easier to work with because the underlying list is accessible as an attribute. class collections. UserList ( [ list ] ) ¶ Class that simulates a list. The instance’s contents are kept in a regular list, which is accessible via the data attribute of UserList instances. The instance’s contents are initially set to a copy of list , defaulting to the empty list [] . list can be any iterable, for example a real Python list or a UserList object. In addition to supporting the methods and operations of mutable sequences, UserList instances provide the following attribute: data ¶ A real list object used to store the contents of the UserList class. Subclassing requirements: Subclasses of UserList are expected to offer a constructor which can be called with either no arguments or one argument. List operations which return a new sequence attempt to create an instance of the actual implementation class. To do so, it assumes that the constructor can be called with a single parameter, which is a sequence object used as a data source. If a derived class does not wish to comply with this requirement, all of the special methods supported by this class will need to be overridden; please consult the sources for information about the methods which need to be provided in that case. UserString objects ¶ The class, UserString acts as a wrapper around string objects. The need for this class has been partially supplanted by the ability to subclass directly from str ; however, this class can be easier to work with because the underlying string is accessible as an attribute. class collections. UserString ( seq ) ¶ Class that simulates a string object. The instance’s content is kept in a regular string object, which is accessible via the data attribute of UserString instances. The instance’s contents are initially set to a copy of seq . The seq argument can be any object which can be converted into a string using the built-in str() function. In addition to supporting the methods and operations of strings, UserString instances provide the following attribute: data ¶ A real str object used to store the contents of the UserString class.

OpenAI Open in ChatGPT Customising tenant By default tenantId prop is set to default tenant. If you use multi-tenant architecture and want to fetch inbox notifications of other tenant, you can pass tenant_id prop. Inbox Feed Copy Ask AI suprsendConfig = { inbox: { tenantId: "suprsend" } }; If you are passing tenant_id in feed, make sure to pass scope key while creating userToken else 403 error will be thrown due to scope mismatching. Adding tabs You can pass stores prop to add multiple tabs in feed. For each tab you can write your own logic to get notifications based on tags, notification categories and notification status like read, archived. Read more about it here . Inbox Feed Copy Ask AI suprsendConfig = { inbox: { stores: [ { storeId: "All" , label: "all" }, { storeId: "Archived" , label: "archived" , query: { archived: true } }, ], }, }; Disable pagination By default, feed supports infinite scrolling type pagination to get older notifications when you scroll through notifications list. If you want to remove infinite scroll, that is stop getting previous page notifications, you can set pagination=false . Inbox Feed Copy Ask AI suprsendConfig = { inbox: { pagination: false } }; Enable dark mode Inbox Feed Copy Ask AI suprsendConfig = { inbox: { themeType: "dark/light" } }; Light Theme Dark Theme Custom notification card click handler Clicking on notification card will open the link if Action URL field is present in triggered inbox template. If you want to override this with your custom callback function you can pass notificationClickHandler . Inbox Feed Copy Ask AI suprsendConfig = { inbox: { notificationClickHandler: { ( notificationData: IRemoteNotification ) => { console . log ( "notification clicked" , notificationData . n_id ); } } } } Custom action button click handlers Clicking on action buttons in notification card will open link if you provide the URL on action button fields in triggered inbox template. If you want to override this with your custom action button callback functions you can pass primaryActionClickHandler and secondaryActionClickHandler . Inbox Feed Copy Ask AI suprsendConfig = { inbox: { primaryActionClickHandler = { ( notificationData: IRemoteNotification ) => { console . log ( 'primary action button clicked' , notificationData . n_id ) } } secondaryActionClickHandler = { ( notificationData: IRemoteNotification ) => { console . log ( 'secondary action button clicked' , notificationData . n_id ) } } } } Popover position Popover component is wrapper around NotificationFeed component and will be opened on click of bell icon. By default popover is shown at bottom, that is the inbox notifications popup list will be shown at bottom of the bell icon. Example: Feed needs to be shown at bottom of left sidebar above profile icon, in that case on click of bell icon you would want to show notifications popover at right side. Inbox Copy Ask AI suprsendConfig = { inbox: { popperPosition: "top / bottom / left / right" } } Customising CSS styles You can customize the CSS of the provided components by passing theme prop. You can pass the styles for the following components: Inbox Feed Toast Copy Ask AI interface ITheme { bell ? : { height ? : number | string ; width ? : number | string ; color ? : string ; }; badge ? : React . CSSProperties ; header ? : { container ? : React . CSSProperties ; headerText ? : React . CSSProperties ; markAllReadText ? : React .

If you want to use other languages that are not supported by us or to override strings of existing languages, you can pass translations object. en - English (default) fr - French de - German es - Spanish ar - Arabic Inbox Feed Translations Object Copy Ask AI suprsendConfig = { locale: "fr" }; suprsendConfig = { translations: { "notifications" : "All Notifications" , "markAllAsRead" : "Mark Read All" } }; Was this page helpful?

(" 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.

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.

(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 .

Report Abuse nabbisen Posted on Feb 12, 2025 • Originally published at scqr.net Svelte 5 on Bun 1.2: 始め方 # svelte # bunjs # javascript # typescript はじめに Svelte 最新版 5 では、 $: に代わるリアクティビティへの新しいアプローチとしてルーンが導入されました。 Svelte 4 のプロジェクトを 5 に移行する ためには、やらなければならないことがそれなりにあります。それは言っても、ルーンシステムのおかげで、開発者はより優れた柔軟性とパフォーマンスの向上を享受できるようになりました。今回のアップデートでは、アプリをより効率的で保守しやすいものにすることが企図されています。 本記事で Bun での Svelte 5 プロジェクト開発の始め方をご説明します。 環境 アプリ: Svelte 5.19.9 + SvelteKit , "a framework for rapidly developing robust, performant web applications using Svelte" (私訳: 堅牢かつ高性能な Web アプリを高速に開発するための Svelte のフレームワーク) JavaScript ランタイム: Bun 1.2 .2 OS: CathyOS ( Linux ディストリビューション) チュートリアル 簡潔に言うと、手順はわずかです。コマンドラインを実行すれば、すぐに完了します。 1. プロジェクト作成 $ bunx sv create sveltekit-example Enter fullscreen mode Exit fullscreen mode インストーラーがいくつか質問して来ます。以下は私の回答例です: ┌ Welcome to the Svelte CLI! (v0.6.20) │ ◇ Which template would you like? │ SvelteKit minimal │ ◇ Add type checking with Typescript? │ Yes, using Typescript syntax │ ◆ Project created │ ◇ What would you like to add to your project? (use arrow keys / space bar) │ prettier, eslint │ ◆ Successfully setup add-ons │ ◇ Which package manager do you want to install dependencies with? │ bun │ ◆ Successfully installed dependencies │ ◇ Successfully formatted modified files │ ◇ Project next steps ─────────────────────────────────────────────────────╮ │ │ │ 1: cd sveltekit-example │ │ 2: git init && git add -A && git commit -m "Initial commit" (optional) │ │ 3: bun run dev --open │ │ │ │ To close the dev server, hit Ctrl-C │ │ │ │ Stuck? Visit us at https://svelte.dev/chat │ │ │ ├──────────────────────────────────────────────────────────────────────────╯ │ └ You're all set! Enter fullscreen mode Exit fullscreen mode プロジェクトが作成され、準備が整いました。進めて行きましょう: $ cd sveltekit-example Enter fullscreen mode Exit fullscreen mode なお、初期時点でのディレクトリとファイル群は次の通りです (選択肢で選んだオプションの内容も含まれています): $ ls -a1F ./ ../ .svelte-kit/ node_modules/ src/ static/ .gitignore .npmrc .prettierignore .prettierrc bun.lock eslint.config.js package.json README.md svelte.config.js tsconfig.json vite.config.ts $ find src/ src/ src/app.html src/app.d.ts src/lib src/lib/index.ts src/routes src/routes/+page.svelte Enter fullscreen mode Exit fullscreen mode 2. デモアプリ実行 ミニマルテンプレートでのアプリデモを実行してみましょう: $ bun run dev --open Enter fullscreen mode Exit fullscreen mode 次のように表示されます: 実行プロセスはファイル変更を監視します。何らかの変更を検出すると、ブラウザのページを更新して再レンダリングを促します。 3. カスタマイズ ここまでで、独自のアプリを作成する準備が整いました。たとえば src/routes/+page.svelte を以下のように変更してみましょう: <script lang= "ts" > let counter : number = $state ( 0 ) const incrementCounter = () => counter ++ </script> <div class= "container" > <div class= "output" > { counter } </div> <button onclick= { incrementCounter } > Increment </button> </div> <style> .container { padding : 0.8rem 0.2rem ; display : flex ; justify-content : center ; border : 0.5em solid #fdfa72 ; border-radius : 1.4rem ; } .output { width : 2.5em ; margin-right : 0.8rem ; color : #4f68dc ; text-align : right ; font-size : 1.2rem ; font-weight : bold ; } </style> Enter fullscreen mode Exit fullscreen mode 次のように表示されます: +layout.svelte のような Svelte コンポーネントを追加したり、独自の コンポーネント / レイアウト / スタイル / 型 を定義したりもできます。 おわりに Svelte 5 では、 $: がルーンに置き換えられました。これはリアクティビティの核となるものをより良くするためです。そのおかげでコンポーネントの更新が、より明確かつ効率的になっています。また、大規模プロジェクトで、より優れたスケーラビリティを発揮できるようにという観点でも工夫が施されています。 Svelte 5 で最新の洗練されたアプリ開発をお楽しみください :) Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

(" 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.

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 .

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 .

But like any powerful tool, it needs to be carefully handled. If used well, you can send 100s of notifications to your users without them realizing it. Chat apps like Slack are a great example of that. But when mismanaged, they also have the potential to overwhelm and drive users away. Users seek the delicate equilibrium between staying informed and avoiding interruptions and this choice is unique to each users’ preferences. Your product will have a whole spectrum of user types, from new users to power users, or users with different roles in a company, who not only have a different tolerance to the volume of notifications but different channel preferences, and different timings in which they engage with their devices. So, how do you cater to these varied choices and give a personalised experience to your users? The answer lies in granting them control. Instead of struggling to create a blanket solution, you can empower your users to set their own notification preferences. They get to decide the type of notifications they receive, where they receive them, and how often they hear from you. In this article, we’ll cover how you can create the best notification preference experience within an hour . The Why behind Notification Preferences Notification preferences are a way for users to configure how and when they would like to be notified of anything important happening within the product or service. Apart from the fact that it gives your users control over their notification experience, it is a must have feature for any product for various reasons - Did you know that an average user receives 46 push notifications, 121 emails and 32 text messages every day? Mitigating Notification Fatigue: Users get frustrated when they don’t get the option to turn off certain types of notifications. There is an old article in new york times of a user frustrated with facebook’s overwhelming notifications. Compliance and Consent: In some countries, data privacy and regulation acts like GDPR (General Data Protection Regulation), CCPA (California Consumer Privacy Act) require you to take user’s consent to send them communication and also an option to opt-out. Preferences serve as tangible proof of user consent here. Marketing Insights : Notification preferences extend beyond user experience; they also offer valuable insights. By understanding which channels and topics most of your users prefer, you can send more targeted campaigns to your users. Most marketing platforms still offer limited preference control, often allowing users only to switch all notifications on or off, which is not a great idea anymore. Preventing Complete Notification Disengagement: When not given the option to set notification preferences at granular level, users often resort to extreme measures and end up turning off all notifications for a channel. This includes marking your emails as spam, opting-out from text messages, or turning off mobile notifications from application settings. Such drastic actions leads to a complete loss of touch base on that channel, even for critical notifications. Crafting the Best Preference Experience The best preference control is the one which provides granular control for every user’s needs. Platforms like Slack do a great job here, where you can customize notification sounds, choose when to be alerted and which notifications should be silent. You can also set mobile push notifications during periods of inactivity. Slack Notification Preferences Most successful apps like Linkedin, Quora, Teams build highly customizable preference control. Follow these steps to create an advanced preference centre akin to these platforms: 1. Start by Understanding your users Before designing your preference centre, take a moment to empathize with your users and try to understand what level of control they would need in your platform. Is there just one tenant in your system or multiple tenants who control the preferences, like an admin of an organization. Is your user base spread across different corners of the world, each ticking to a different time zone ? Perhaps your product can send notifications at odd hours, demanding a feature that lets users dictate their own "off" time. At what frequency would they like to be notified, instantly, or a daily / weekly digest? By gaining insight into your users' needs, you'll be better equipped to design a preference center that resonates with their unique requirements. 2. Create notification categories and unsubscription rules You might be sending 100 notifications to a user on a daily basis. Setting preferences for each notification can be very confusing. To handle this, we have introduced notification categories in SuprSend. You can group similar notifications into a notification category for easy reference. You can also club categories into sections for even cleaner mapping. For example, “payment reminders” and “invoices” category can be grouped under “Payment” section. While we are all in for granting user control, certain notifications like "Email Verification" are critical and should not be turned off even if users decide to disable the rest. As a developer, you can determine default notification behaviours, and mark such critical notifications as "can't unsubscribe" . Users can’t completely disable these notifications, reassuring that they receive critical notifications irrespective of their choice. 3. Provide a way for users to set their preferences Create an intuitive preference centre UI which is easily accessible to your users. You can embed a ready preference centre inside your application using our frontend SDKs or APIs . The page is designed to be easily navigable, where toggling preferences for notification topics and channels is as simple as a mouse click. By default, SuprSend creates a hosted preference page for capturing out of product user preferences. No sign-up required, facilitates getting preferences from unregistered users. 4. Offering Granular Customization to your users Every user has a unique way of engaging with your product. Your power users might want to know about every new product update, while managers might want to subscribe to a few categories, and to a summary of all activities once in a day in the form of digest. Some users might like a real-time alert, while others might just want an in-app feed that they can view in their own time and space. Here’s the level of granularity that you can handle inside SuprSend: A. Opting out of notification categories and setting preferred channels A major source of user frustration arises when marketing and transactional notifications invade the same channels. Also, the choice of channel also varies depending on the type of notification type. For example, I like to receive offers and product updates on email, whereas important alerts around direct messages on Slack. With SuprSend , users can opt-out of notification categories, channels or handpick their preferred channels inside each category . B. Finding the Sweet Spot: Setting Notification Frequency A common mistake when implementing preferences is offering a binary choice: all notifications or none at all. Frequently, users need a middle ground. For instance, not every Quora user may wish to receive instant notifications for a new story recommendation and instead want a daily / weekly digest of all the recommendations in a single notification. This can be solved with batched notifications (digests) and offering users the flexibility to set their preferred notification frequency —immediate, daily, or weekly. Quora : Option to set Digest Frequency C. Setting notification schedule / out of office hours In our fast-paced world, everyone needs some peaceful time. Respect users' downtime by allowing them to set notification schedules aligned with their work hours or personal time. While you are giving this support, you should also accommodate for user timezones. Setting Notification Schedule in Slack 5. Giving Preference control at multiple user levels SuprSend’s preference management functionality supports multi-level preference control . Intra-organizational Use Case: In complex organizations with multi-level hierarchy, admins can set notification preferences for all users at the account level, and end users can further set their individual preferences. Multi-Tenant Communication: In multi-tenant communication, your tenants can control what notifications should be sent to their users and on which channels. Combine it with a whole suite of capabilities available for multi-tenant communication to give a 360 degree solution to your users. 6. Storing user preferences and applying it in workflow runs Maintain synchronization between user preferences and notification workflows through SuprSend's real-time preference synchronization . User preferences are automatically stored in the SuprSend database, ensuring seamless alignment between user settings and actual notification execution. 7. Visibility and logs: Know when someone opts out Know when someone opts out of notifications through SuprSend logs. Maintaining logs aids in debugging, compliance, and customer support. You can also check the latest user preferences on SuprSend dashboard, or via API. 8. Testing and Iteration Continue to collect user feedback and iterate on your preferences. You can easily preview and test your new preference changes in the staging environment (used for testing your notification changes) before deploying them to production. Get started with SuprSend Preferences today Integrating preference management into your notification strategy can yield benefits that extend beyond user satisfaction. With SuprSend Preferences, you can save months of effort and go live with an advanced preference centre in less than an hour.

In this article, we'll explore how to optimize a notification service using Ruby on Rails for the API server and Sidekiq for background job processing. Architecture Overview Our optimized notification service will consist of the following components: API Server : A Ruby on Rails application that exposes an API for triggering notifications. Background Processing : Sidekiq, a background job processing library for Ruby, to handle time-consuming tasks and improve performance. Database : PostgreSQL or MySQL for storing notification data and managing real-time updates. Designing the API Server with Ruby on Rails Use Ruby on Rails : Leverage the Ruby on Rails framework to build a robust and scalable API server for handling notification requests. Implement RESTful endpoints : Design RESTful endpoints for creating, updating, and deleting notifications. Utilize ActiveRecord : Use ActiveRecord, Rails' ORM (Object-Relational Mapping) library, for interacting with the database and managing notification data efficiently. Copy Code # Example of a NotificationsController in Ruby on Rails class NotificationsController Implementing Background Processing with Sidekiq Integrate Sidekiq : Integrate Sidekiq into your Ruby on Rails application to offload time-consuming tasks, such as sending notifications, to background workers. Define Sidekiq workers : Create Sidekiq worker classes to perform specific tasks asynchronously, ensuring that the main application remains responsive. Use Redis for job queuing : Sidekiq relies on Redis for job queuing, so ensure that Redis is properly configured and running. Copy Code # Example of a Sidekiq worker for sending notifications class NotificationWorker include Sidekiq::Worker def perform(notification_id) notification = Notification.find(notification_id) # Logic for sending the notification end end Scalability and Performance Optimization Horizontal scaling : Scale your Ruby on Rails application horizontally by deploying multiple instances behind a load balancer to handle increased traffic. Caching : Implement caching strategies using tools like Redis or Memcached to reduce database load and improve response times. Monitoring and optimization : Use tools like New Relic or Scout to monitor performance metrics, identify bottlenecks, and optimize the notification service for efficiency. By optimizing a notification service with Ruby on Rails and Sidekiq, you can enhance performance, scalability, and responsiveness, ensuring timely delivery of notifications while maintaining system efficiency. Remember to continuously monitor and fine-tune your setup to meet evolving demands and maintain optimal performance.

(" 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 ).

(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.

(" 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.

(" 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.

Report Abuse Omer Dahan Posted on Dec 13, 2025 • Originally published at blog.does.center Quantum Computing & Minimal Energy States: Unlocking Revolutionary Potential for Israeli Innovation # energy # quantum # science Quantum computing takes us on a journey to the very limits of nature—a realm where the classical rules of physics fade into a landscape dominated by the peculiar behavior of atoms and subatomic particles. Rather than examining large-scale objects or everyday phenomena, quantum engineers harness the extraordinary properties of matter at its most fundamental level. In doing so, they explore the unique energy states of particles and the inherent potential locked within the quantum vacuum. Imagine the quantum world as an expansive, invisible stage where atoms and particles perform a dance governed not by definite positions and trajectories, but by probabilities and energy fluctuations. Unlike traditional computers that process bits in a clear-cut 0 or 1, quantum systems use quantum bits, or qubits. These qubits can exist in superpositions—essentially a blend of states—lifting computational capabilities to heights that can, in theory, solve problems far too complex for classical machines. One of the central features that intrigues researchers is the tendency of these particles to settle into the lowest possible energy configuration—often referred to as the ground state. Why is this transition to the lowest energy state so critical? Simply put, it allows scientists to tap into a realm of stability and predictability amidst quantum chaos. When a system minimizes its energy, its behavior becomes slightly easier to predict and control, which is essential when you’re trying to harness quantum phenomena for practical applications. In the world of quantum computing, preparing a system in its ground state is akin to setting up the perfect starting point for a race. Everything begins in a controlled, stable configuration, ensuring that any computations performed have a reliable baseline. Achieving this state, however, is far from trivial. It involves cooling systems to near absolute zero, isolating them from external disturbances, and employing sophisticated techniques to manipulate and observe quantum states without causing unwanted disturbances—a process known as decoherence. The benefits of operating at or near the lowest energy state are manifold. For one, it enhances the coherence time of qubits—the duration during which they maintain their quantum properties. In practical terms, a longer coherence time means more complex computations can be performed before random errors, introduced by environmental noise, start interfering with the results. This is extremely significant because one of the major hurdles in quantum computing is managing these delicate quantum states before they collapse into classical bits. Let’s delve into some relatable examples and use-cases that illustrate how quantum computing—and its focus on minimal energy states—can revolutionize various fields. Consider the task of simulating complex chemical reactions. In classical computing, simulating the exhaustive interactions among numerous electrons is exceedingly resource-intensive, often requiring simplifying assumptions that can diminish the accuracy of the simulation. Quantum computers, by contrast, naturally operate on the same quantum principles governing the chemicals themselves. When initialized in a stable, low-energy condition, these machines can mirror chemical behaviors with far greater fidelity. This progress could lead not only to the design of new, effective pharmaceuticals but also to the discovery of novel materials with tailored properties. Another promising domain is optimization. Many real-world problems—from routing logistics in transportation networks to financial modeling—require sifting through vast numbers of potential solutions. Traditional computers, despite their power, struggle to efficiently navigate these immense solution spaces. Quantum algorithms, such as the quantum annealing process, rely on gradually lowering the energy of a system to find an optimal or near-optimal answer. By exploiting the nuances of the quantum vacuum and the natural inclination of particles to adopt the lowest energy configuration, these algorithms can often uncover solutions much faster than brute-force methods on classical hardware. Security, too, stands to gain tremendously from quantum techniques. Modern cryptography largely depends on the difficulty of factoring large numbers—a task at which classical computers already excel in making secure communications with current technology. However, quantum algorithms like Shor’s algorithm promise to crack these cryptographic codes by reducing computational complexity drastically. While this presents a looming threat to existing encryption methods, it simultaneously paves the way for developing new quantum-resistant protocols, ensuring that secure communication can continue in an increasingly digital and interconnected world. Diving deeper into the mechanics of quantum systems, it becomes clear that the quantum vacuum isn’t empty at all, but teems with fluctuations and transient particles. These tiny disturbances—even in seemingly void space—are a vivid reminder that the universe operates on a spectrum of continuously shifting energy levels. Quantum computing seeks to harness this seemingly chaotic environment by steering systems toward configurations that are both predictable and functional. Scientists achieve this by meticulously designing experimental setups where external influences are minimized, while the natural tendencies of particles to settle into their ground states are encouraged. The engineering challenges here are considerable. Devices must operate in ultra-low temperature environments created by sophisticated dilution refrigerators, while entire laboratories are isolated from vibrations, electromagnetic interference, and other unwanted disturbances. Each qubit’s environment is carefully controlled down to minute details so that once the system cools into the ground state, it remains stable long enough for calculations to occur. This marriage of advanced cryogenics, precision engineering, and quantum mechanics embodies one of the great engineering feats of our time. Furthermore, the conceptual foundation of using minimal energy states extends beyond mere stability—it also opens the door to error correction strategies essential for scaling up quantum computers. Quantum error correction exploits the indistinct boundaries between quantum states. When qubits are in their lowest energy state, they are less prone to random transitions that cause computation errors. Researchers build error correction algorithms that take advantage of this low-energy configuration, creating redundant pathways that help identify and correct mistakes before they propagate through the computation. This level of fault tolerance is vital for transitioning from experimental quantum machines to commercially viable devices that can solve real-world problems. Perhaps one of the most fascinating aspects is how quantum mechanics challenges our traditional understanding of reality. In classical physics, objects have well-defined positions and velocities. In the quantum domain, however, particles can occupy multiple energy states simultaneously until measured. This counterintuitive behavior is not a bug, but the very essence of what gives quantum computing its power. Instead of being hampered by uncertainty, quantum systems leverage it to explore many computational pathways at once, dramatically accelerating the problem-solving process. This principle is frequently illustrated in thought experiments like Schrödinger’s cat, which underlines the surreal interplay between observation, measurement, and reality. In summary, the pursuit of the lowest energy state in quantum computing is more than a technical necessity—it is a doorway into a deeper understanding of nature. By aligning their research with the natural inclinations of subatomic particles, scientists unlock new potentials in simulation, optimization, and security that promise to redefine industries and solve long-standing challenges. The quantum vacuum, far from being a barren void, is a vibrant source of computational power waiting to be harnessed through careful manipulation and advanced engineering. As we continue to refine these technologies, the quantum revolution is poised to transform not just the field of computing, but the very fabric of scientific inquiry and practical problem-solving. Researchers and industry leaders around the globe are building upon these principles with the hope that one day, stable, error-corrected quantum processors will tackle problems from climate modeling to complex financial systems, ushering in an era of unprecedented innovation. The interplay between ultra-low energy states and the wild fluidity of the quantum world stands as a testament to human ingenuity—a bridge between the abstract and the tangible that promises to reshape our understanding of what is computationally possible. 🔗 Originally published on does.center 👉 https://blog.does.center/blogpost?slug=quantum-computing-minimal-energy-states Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Pixel Mosaic Posted on Dec 4, 2025 React Performance Optimization: 12 Tips Every Developer Should Know # javascript # webdev # react # performance React apps often become slower as they grow — unnecessary re-renders, heavy bundles, and sluggish interactions all contribute to poor performance. The good news? Most bottlenecks can be fixed with simple optimization techniques. Here are 12 essential tips every React developer should know. 1. Use React.memo Prevents a component from re-rendering when its props haven't changed. 2. Use useCallback and useMemo Memoize functions and heavy computations to avoid recreating them on every render. 3. Code-Split with React.lazy Load components only when needed to keep bundles small and initial load fast. 4. Virtualize Large Lists Use libraries like react-window to render only visible items instead of thousands of DOM nodes. 5. Avoid Anonymous Functions in JSX Create functions outside JSX to avoid new references every render. 6. Keep State Local Avoid lifting state too high — it causes entire component trees to re-render unnecessarily. 7. Optimize Context Usage Large contexts cause large re-render waves. Split context or use lightweight alternatives like Zustand, Jotai, or Recoil. 8. Memoize Expensive Calculations Wrap heavy logic inside useMemo to avoid recalculating on every update. 9. Use Production Builds Production mode removes warnings and optimizes performance. Always deploy with npm run build. 10. Use the React Profiler Use React DevTools Profiler to find slow components, wasted renders, and bottlenecks. 11. Keep Props Stable Inline objects/arrays create new references. Memoize them to prevent unnecessary re-renders. 12. Debounce or Throttle High-Frequency Events Reduce DOM updates by limiting how often input, scroll, or mouse events trigger state updates. Best Practices Keep components small and focused Use SSR (Next.js, Remix) for faster load Analyze bundle size regularly Cache API requests with SWR or React Query Remove heavy, unused dependencies Conclusion React performance optimization is not about a single trick — it’s a collection of small, intentional choices.

The integration was seamless, and the testing and logging are top-notch.

(" 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.

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).
