Raising an exception means that if you fail to put it in a try/except, you get a traceback that walks you through the exact location of the problem. Returning a special value means that if you fail to test the value, you either get an exception further on (if you get back None and try to treat it as a string, for instance), or get incorrect results, with no indication of the actual cause of the problem. Which would you prefer? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
