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).

Performance of list vs. set equality operations
Hello! Could you please confirm whether my understanding of equality operations in sets and lists is correct?

imports again

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

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

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).
