6,063 PointsWhen asked how many tickets I input negative number (-5) and still sold me tickets ?
It still sold me tickets after answering negative number (-5) and gave me a total due of -48 and increased the number of tickets for variable tickets_remaining to 105 . How do we prevent that from happening ?

if num_tickets < 1:
raise ValueError("We cannot sell less than 1 ticket!")
