s-expression parser in python
Hello All, I want to use an s-expression based configuration file format for a python program I'm writing. Does anyone have a favorite parser? I'm currently using sexpy.parse() (http://pypi.python.org/pypi/sexpy) which works very well but I don't know how secure it is. Does anyone have experience with sexpy... 6 Apr 2010 22:03

python as pen and paper substitute
Hello everyone, I am looking for ways to use a python file as a substitute for simple pen and paper calculations. At the moment I mainly use a combination of triple-quoted strings, exec and print (Yes, I know it's not exactly elegant). To clarify, I just start an editor, write a file that might look something li... 10 Apr 2010 10:11
Performance of list vs. set equality operations
Hello! Could you please confirm whether my understanding of equality operations in sets and lists is correct? This is how I think things work, partially based on experimentation and the online documentation for Python: When you compare two lists, *every* element of one of the lists is compared against the ele... 10 Apr 2010 22:17
imports again
Sorry this is a forward (long story involving a braille notetaker's bad copy/paste and GMail's annoying mobile site). Basically, I am getting errors when I run the project at http://www.gateway2somewhere.com/sw.zip and I do not understand why. The bad line was working until I added more import statements. I know m... 7 Apr 2010 12:20

Recommend Commercial graphing library
Hi, I'm on the hunt for a good quality commercially licensed graphing / plotting library and wondered if anyone here had any recomendations. The work to be done is less scientific, more presentational, (I'm not going to be dealing with heatmaps / vectors etc.., just the usual bar / line / bubble / radar / iceber... 8 Apr 2010 17:25
Loading an imported module (C API)
Hi, I am running a simulation where the python module has already been imported. Could you please tell me how to load it? I've been doing this (importing everytime), but it is too slow: pModule = PyImport_Import(pName); Yours, Boon ... 8 Apr 2010 07:13
pass object or use self.object?
Hi, I have a few classes that manipulate documents. One is really a process that I use a class for just to bundle a bunch of functions together (and to keep my call signatures the same for each of my manipulator classes). So my question is whether it's bad practice to set things up so each method operates on se... 9 Apr 2010 04:31
