Do you know of a way to list the users on a Win2K machine? I can't seem to find a module for this. Thanks. -- http://mail.python.org/mailman/listinfo/python-list

Re: Calling a C program from a Python Script

I would expect C to run circles around the same operation under Python. As a general rule of thumb, you should use C for time cirtical operations (computer time, that is), and use Python for human time critical situations (you can get a program developed much faster). I just discovered a magical
