I think you want to overload the [] operator. You can do it by defining the __getitem__ method.

You can serialize on the fly (via pickle or cPickle, like shelve.py does) every key, as well as every value. It's not really worth subclassing shelve.Shelf since you'd have to subclass almost every method -- for once, I'd instead recommend copying shelve.py into your own module and editing it to suit.

You can use the wordnet package to find synonyms with the same 'sense' for nouns and verbs. But this will be a lot dumber than you want. You're looking for like, machine translation from casual english to formal english. Tough question and cool. Props to you.

Chaining mode such as ECB makes no sense for RSA, unless you are doing it wrong. ECB is for block ciphers: the input data is split into equal-size blocks, and each block is encrypted separately. This induces some weaknesses so ECB mode is best avoided for block ciphers. RSA is not a block cipher. In particular, RSA nec...

No, you can not rely on it for any real statistical purpose.

My understanding is that PHP was designed with Internet/Web in mind, but Python is for a more general purpose. Now most people are leaving mod_python for mod_wsgi, which is more robust and flexible. To answer other questions: speed: python is faster. (PHP is slower than both ruby and python) productivity: at least the...

I've recenlty discovered python and its real power (I still don't understand why this is not always the best product that becomes the most famous). I've just discovered mod_python for Apache.

Sorting is done by the database. If you database doesn't support natural sorting your are out of luck and have to sort your rows manually after retrieving them via sqlalchemy.

Currently, i am querying with this code: meta.Session.query(Label).order_by(Label.name).all() and it returns me objects sorted by Label.name in this manner ['1','7','1a','5c']. Is there a way i can have the objects returned in the order with their Label.name sorted like this ['1','1a','5c','7'] Thanks!

No, you can define multiple classes (and functions, etc.) in a single file. A file is also called a module. To use the classes/functions defined in the module/file, you will need to import the module/file.

I'm an extension noob. What I want to do is create an extension that doesn't require other libraries to be installed. Is this impossible because the extension has to link against a specific version of libpython at runtime?

Bash (and the original Bourne sh and myriad derivatives) is - from one perspective - an incredibly high-level language. Where many languages use simple primitives, shell primitives are entire programs. That it might not be the best language to express your tasks, doesn't mean it is dead, dying, or even moribund.

I am currently learning PHP and want to learn about OOP. I know Python is a well-organized and is all OOP, so would learning Python be a wise choose to learn OOP? The thing is I am more towards web development then just general programming, and I know Python is just a general purpose language, but there is Django. ...
How should I go about learning Python?

My friend said, "Pylons is so much better for web services." My other friend said, "You can modify Django in a way to do exactly whatever you like." In Django, what is necessary to be modified (urls.py? models classes? settings?) in order to do "web services" with APIs and REST and versioning, etc etc.?
Can Django be used for web services?

Absolutely. Django is in fact made to be used on server side. But first you need to understand that it is a framework. A framework is a set of tools which get the common activities done in web development (e.g Login or Sign up module).

Instead of using a list, why not use a dictionary and use small integers as the keys? Adding and removing items from the dictionary will not change the indices into the dictionary. You will want to keep one value in the dictionary that lets you know what the next assigned index will be.

A UUID seems perfect for this. Why don't you want to do that? Do the items have any sort of product_id? Can the shopping cart have more than one of the same product_id, or does it store a quantity? What I'm getting at is: If product_id's in the cart are unique, you can just use that.

If your function is looping through a lot of things, you could check the elapsed time during each iteration of the loop... but if it's blocked on something for the long period, then you need to have some other thread which can be handling the timing stuff while the thread you're timing is blocked.

Late binding is a very different concept to interpretation. Strictly speaking, an interpreted language is executed directly from source. It doesn't go through a byte-code compilation stage. The confusion arises because the python program is an interpreter, but it interprets the byte-code, so it is Python's byte-code la...

There's no such requirement to give variables different names in different methods or function arguments. In fact, it would greatly hurt readability and go against common sense -- when two things are the same, one tries to give them the same name, not different ones.

I tend to reuse variable names in local functions a lot, as long as they are mid-process. Usually 'result' for a db lookup or a calculation that is used intermediary and is needed to generate or construct the end-result of the method. Only rarely have I used global variables, in fact only if I must.

A web application framework is independent of the actual HTTP server in use. The server passes an application written using it the requests, and it cranks some gears and spits out a response, which is sent back to the HTTP server. Django has 3 popular connectors to the HTTP server: WSGI, FastCGI, and mod_python. These ...

I'm getting into python for cgi and came across Django. I'm not quite sure I understand it very much. Is it something I have to install inside apache or is it just something I can use with my cgi? Wanted to know because I'd love to learn it but my server I'm using doesn't give me a lot of privileges. thanks
What exactly is a web application framework?

Basically the functions of any framework are:- make sure that you do not have to do the repetitive tasks. make it easy for you to re-use and modularize they provide a layer of abstraction(which in most cases, makes you more productive) So, Django is a web application framework; naturally it satisfies all three condit...

A web application framework like Django replaces CGI by spawning its own processes and handling requests from a web server. They also provide tools for simplifying html by creating templates, partial templates, helpers etc. If you don't have full control over your server, your host will need to install it for you.

If your definition of barcode functionality is the ability to read and write barcodes, you should keep in mind two things. Barcodes are actually read by barcode readers, and from the computers' point of view they are just input devices, just like keyboards. When the reader reads a barcode, it just "types" it in, chara...

Data encapsulation in Python is enforced by convention and peer review. Surprisingly, having every attribute effectively be public hasn't caused a problem for the majority of Python programmers.

in python tutorial added that python cannot hide its attributes from other classes. some thing such as private data in C++ or java..But also i know that we can use _ or __ to set some variables as privated one but it is not enogh. I think it is a weak if it is not any thing to do it.

Using an underscore at the start of the name for an element or a method signals to the reader that what they're looking at is "internal implementation details". If they want to use that, they can, but it is very likely that a new version of the class will not preserve the API for internal-only method or elements (eh, "...

You are right that the _foo convention isn't sufficient to make data private; it's not supposed to be! Information hiding is not part of the design of Python. When writing programs in Python, you depend on the caller's good manners to leave your internals alone based on the naming convention and your documentation. Don...

Huffman code doesn't care about characters, it cares about symbols. Generally, it is used to encode the alphabet / other single characters, but can very easily be generalized to encode strings of characters. Basically, you would just take an existing implementation and allow symbols to be strings rather than characte...

I need huffman code(best in python or in java), which could encode text not by one character (a = 10, b = 11), but by two (ab = 11, ag = 10). Is it possible and if yes, where could i find it, maybe it's somewhere in the internet and i just can'd find it?

There is probably some code somewhere. But this sounds like a parsing and tokenising question. One of the first questions I would be answering is how many unique pairs are you dealing with. Huffman encoding works best with small numbers of tokens. For example, the 101 characters on your keyboard. But if your two charac...

I don't think a wxFrame can return a value since it is not modal. If you don't need to use a wxFrame, then a modal dialog could work for you. If you really need a frame, I'd consider using a custom event. It would go something like this: (1) User clicks to close the wxFrame (2) You override OnClose (or something li...

Could someone show me how I could return a value from a wxPython Frame? When the use clicks close, I popup a message dialog asking him a question. I would like to return the return code of this message dialog to my calling function. Thanks

I wrote a python script that depends on a certain NFS share to be available. If the NFS share is not mounted it will happily copy the files to the local path where it should be mounted, but fail later when it tries to copy some files back that were created on the NFS server. I'd like to catch this error specifically s...
