You've got a function written to take a list arg and are passing it something other than a list. Why do you expect it to work? As soon as the function uses lst[3] for something, it will crash if you pass it a sequence like that. Your example is mainly an argument for static type checking. -- http://mail.python.org/mailman/listinfo/python-list
