Thank you for the clarification, bob. For any future readers of this thread I include this link[1] to effbot's guide on lists, which I probably should have already read.
My intention now is to modify list contents in the following fashion: for index, value in enumerate(L): L[0] = some_func(value) Is this the standard method? [1]: http://effbot.org/zone/python-list.htm Colin Caine
