You're of course right. Exceptions are mainly a way of handling 'exceptional' conditions without cluttering the source code with error code checking. The canonical use case is: try: some_call_that_may_raise(args) except SomeException, e: try_to_solve_the_problem() The nice thing with exceptions (compared to 'manual' error handling) is that you can choose where you want to handle the problem without having to pass back error code/error message all along the call stack... -- http://mail.python.org/mailman/listinfo/python-list
