That is because you typoed what kynn wrote. >>> re.sub('/?$', '/', 'aaabbb') 'aaabbb/' >>> That solution is very perl-ish I'd say, IMHO if not url.endswith("/"): url += "/" is much more pythonic and immediately readable. In fact even someone who doesn't know python could understand what it does, unlike the regexp solution which requires a little bit of thought. -- Nick Craig-Wood <n...@craig-wood.com> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
