Because - from a semantic POV - the real error is not that you're trying to divide zero by zero, but that you failed to pass any argument. FWIW, I'd personnaly write avg as taking a sequence - ie, not using varargs - in which case calling it without arguments would a TypeError (so BTW please s/Value/Type/ in my previous post). -- http://mail.python.org/mailman/listinfo/python-list
