496 PointsNegative entry
I was testing this code. Instead of going to 10000 to catch a ValueError, I typed -10. When I completed the transaction, it added 10 to the total. In a real life situation, we probably wouldn't want that problem. How could we remedy that?

230,688 PointsThe easiest solution might be to have another test, such as if num_tickets <= 0
. If that condition is true, you could raise a ValueError with a message like "your entry must be a positive number".
