Is there some way to make a class-level read-only property in Python? For instance, if I have a class Foo, I want to say: x = Foo.CLASS_PROPERTY but prevent anyone from saying: Foo.CLASS_PROPERTY = y EDIT: I like the simplicity of Alex Martelli's solution, but not the syntax that it requires. Both his and ~unutbu's answers inspir...
It's that time of year again that programmers want to shuffle a list such that no element resides on its original position (at least in the Netherlands, we celebrate Sinterklaas and pick straws for deciding who writes who a poem). Does anyone have a nice Python single statement for that? So, input example: range(10) Output example: [2,...
I'm trying to parse words which can be broken up over multiple lines with a backslash-newline combination ("\\n") using pyparsing. Here's what I have done: from pyparsing import * continued_ending = Literal('\\') + lineEnd word = Word(alphas) split_word = word + Suppress(continued_ending) multi_line_word = Forward() multi_line_word << ...
Like the title says, my code basically does this: set proxy, test proxy, do some cool stuff But after the proxy is set the first time, it sticks that way, never changing. This is the failing code: # Pick proxy r = random.randint(0, len(proxies) - 1) proxy = proxies[r] print proxy # Setup proxy l_proxy_support ...
I have a fairly simple app built with pyqt4. I wanted to debug one of the functions connected to one of the buttons in my app. However, when I do the following python -m pdb app.pyw > break app.pyw:55 # This is where the signal handling function starts. things don't quite work like I'd hope. Instead of breaking in the function where ...
hello I have systems of polynomials, fairly simple polynomial expressions but rather long to optimize my hand. Expressions are grouped in sets, and in a given set there are common terms in several variables. I would like to know if there is a computer algebra system, such as Mathematica, Matlab, or sympy, which can optimize multiple p...
Guido van Rossum's presentation about Python 3000 mentions several things to make a transition from Python 2 to Python 3 easier eventually. He is specifically talking about text handling since the move to Unicode as the only representation of strings in Python 3 is one of the major changes. As far as text handling goes, one slide (#14) ...
I'm trying to use bsdiff (or any binary diff implementation you come up with) to compute and apply diff onto random binary data. I would like to use it on data from a database, so it would be better not to have to write those onto disk and pass them to bsdiff.exe. Is there any wrapper library or way in python to do that? ...

I am distributing an app that uses the Python/C API. I have all standard python modules in python31.zip which is basically an archive of the Lib folder in the python install directory.

Screenshot I'm looking to recreate this in Python; I can't find a library that seems to have what I need. Are there any GUI libraries that might possibly have this? - I have scoured wxWidgets (which is my preferred gui library) but they have nothing similar. I have a script already that uses a standard wxTreeCtrl but it has no provisi...
