Different solution of error handling

Hello, I solve error problem in different way then Craig. I raise exception as err, not like in the lesson ValueError twice. Is it correct? Regards Dawid

try: ticket_ammount = int(input("Hello {}, how many tickets do You want?: ".format(name))) if ticket_ammount > tickets_remaining: raise Exception("Sorry! We have only {} tickets".format(tickets_remaining)) except Exception as err: print(err) except ValueError: print("{}, You must type a number!!!".format(name))

When you have a generic exception handler, it should be the last one in the series. Otherwise, the specialized handlers (like the one here for ValueError) will never get a chance to run since the generic one will handle them also.

As long as you observe that rule, using a generic handler is OK.

Thank You!
