For any non-trivial function, I usually start by writing the documentation (a docstring and doctests) first. How else do you know what the function is supposed to do if you don't have it documented? By writing the documentation and examples before the code, I often discover that the API I first thought of was rubbish :) -- Steven -- http://mail.python.org/mailman/listinfo/python-list
