testing for modules?
i have a generic script that is using several modules on windows and linux boxes. i need to have the scripts test if a module is installed, and then if not - then to install the module. can anyone give me a headsup on how to test for a module, returning something to indicate whether or not it is installed, then after that executing file to install the module.? just somewhere to start would be helpful! thanks in advance. -- edward hotchkiss -- http://mail.python.org/mailman/listinfo/python-list

I'm new to Python, not programming. I agree with the point regarding the interpreter. what is that? who uses that!? Why are most examples like that, rather than executed as .py files? Another problem that I have (which does get annoying after awhile), is not using foo and bar. Spam and Eggs sucks. It's not funny, although Monty Python does rock.
