Every function returns a value. If you don't use an explicit return keyword, None is returned implicitly. You print the answer that you are looking for from within your function, then print the return value from that function, which, as I've explained, will be None. -- Cheers, Simon B, [EMAIL PROTECTED], http://www.brunningonline.net/simon/blog/ -- http://mail.python.org/mailman/listinfo/python-list
