Assertions are disabled when you run Python with the -O (optimise) flag. If you rely on assertions to verify data, then any time the user runs python with -O your code will be running without error checking. assert should be used to verify program logic, not to sanitize data. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
