  • Is there any way to run Python on Android ?

    - by e-satis
    I like the Android platform. Actually, with some friends, we even participate to the ADC with the Spoxt project. But Java is not my favourite language at all. We are working on a S60 version and this platform has a nice Python API. Of course there is nothing official about Python on Android, but since Jython exists, does anybody know a way to let the snake and the robot work together ?

  • Including a minified js code in another js library

    - by Nir
    I want to incorporate a minified javascript library (for example http://sizzlejs.com/) into my own non minified javascript library. The reason is that my library plugs into other websites and I don't want to ask them to include the extra library (sizzle) as well. Is there a way to include a minified library in a non minified library and have them both in one js file?

  • Is it guaranteed that False == 0 and True == 1 in Python?

    - by EOL
    Is it guaranteed that False == 0 and True == 1, in Python? For instance, is it in any way guaranteed that the following code will always produce the same results, whatever the version of Python (existing and in the foreseeable future)? 0 == False # True 1 == True # True ['zero', 'one'][False] # is 'zero' Any reference to the official documentation would be much appreciated! Other comments would be appreciated too… :)

  • What's the scope of a Python variable declared in an if statement?

    - by froadie
    I'm new to Python, so this is probably a simple scoping question. The following code in a Python file (module) is confusing me slightly: if __name__ == '__main__': x = 1 print x In other languages I've worked in, this code would throw an exception, as the x variable is local to the if statement and should not exist outside of it. But this code executes, and prints 1. Can anyone explain this behavior? Are all variables declared in a module global/available to the entire module?

  • Why can't I access the instance.__class__ attribute in Python?

    - by froadie
    I'm new to Python, and I know I must be missing something pretty simple, but why doesn't this very, very simple code work? class myClass: pass testObject = myClass print testObject.__class__ I get the following error: AttributeError: class myClass has no attribute '__class__' Doesn't every object in Python have a __class__ attribute?

  • Implement a server that receives and processes client request(cassandra as backend), Python or C++?

    - by Mickey Shine
    I am planning to build an inverted index searching system with cassandra as its storage backend. But I need some guidances to build a highly efficient searching daemon server. I know a web server written in Python called tornado, my questions are: Is Python a good choice for developing such kind of app? Is Nginx(or Sphinx) a good example that I can look inside to learn its architecture to implement a highly efficient server? Anything else I should learn to do this? Thank you~

  • efficiently finding the interval with non-zeros in scipy/numpy in Python?

    - by user248237
    suppose I have a python list or a python 1-d array (represented in numpy). assume that there is a contiguous stretch of elements how can I find the start and end coordinates (i.e. indices) of the stretch of non-zeros in this list or array? for example, a = [0, 0, 0, 0, 1, 2, 3, 4] nonzero_coords(a) should return [4, 7]. for: b = [1, 2, 3, 4, 0, 0] nonzero_coords(b) should return [0, 2]. thanks.

  • Is there any Python library that allows me to parse an HTML document similar to what jQuery does?

    - by Sachin Tendulkar
    Is there any Python library that allows me to parse an HTML document similar to what jQuery does? i.e. I'd like to be able to use CSS selector syntax to grab an arbitrary set of nodes from the document, read their content/attributes, etc. The only Python HTML parsing lib I've used before was BeautifulSoup, and even though it's fine I keep thinking it would be faster to do my parsing if I had jQuery syntax available. :D Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n"

  • Maximal Length of List to Shuffle with Python random.shuffle?

    - by Henrik
    I have a list which I shuffle with the Python built in shuffle function (random.shuffle) However, the Python reference states: Note that for even rather small len(x), the total number of permutations of x is larger than the period of most random number generators; this implies that most permutations of a long sequence can never be generated. Now, I wonder what this "rather small len(x)" means. 100, 1000, 10000,... Can anybody clarify? Thanks!

  • What application you recommend to start peeking to learn Python style?

    - by voyager
    Do you know any application, the more interesting/useful the better, to introduce a new person to Python language and the Python code style, but not necessarily to OO programing, so as to learn the subtleties and idioms of the language and surrounding community? I'm thinking along the lines of people that has worked with JavaScript, Java or .NET, and already have a strong hold of OO concepts.

  • Why is "int + string" possible in statically-typed C# but not in dynamically-typed Python?

    - by Salvador Dali
    While studying C# I found it really strange, that dynamically typed Python will rise an error in the following code: i = 5 print i + " " whereas statically typed C# will normally proceed the similar code: int i = 5; Console.Write(i + " "); I would expect other way around (in python I would be able to do this without any casting, but C# would require me to cast int to string or string to int). Just to highlight, I am not asking what language is better, I am curious what was the reason behind implementing the language this way.

  • What version of Visual Studio is this python compiled with?

    - by leon
    I am trying to find out the version of Visual Study that is used to compile the python on my computer It says Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on win32 What I do not understand is that MSC V.1500. Does it mean it is compiled with 2005? I cannot find this information on `python.org' neither. Any help is appreciated!

  • Looking for a Python IDE with good support for libraries (Twisted).

    - by Omega
    I'm looking for a Python IDE that can help me easily locate and manage and use the libraries on my system (Ubuntu). Specifically Twisted. Code completion is important including the symbols I import. (I've so far had a look at PyDev as well as OpenKomodo, but while both offer code completion for default Python concepts, I wasn't able to get either to import Twisted into my project and was thus getting reference errors.) Usual disclaimer: I don't like EMACS or vi, please, nothing regarding those.
