Question

Suppose you are writing a program to sell tickets to a concert. The maximum number of tickets available is 400. You created your own error type. Class over400error(exception): pass what is the missing term in the code that handles that error? if tickets > 400: over400error.

Answer 1

The missing term to handle the error in the code for selling tickets is the 'raise' statement, which triggers the custom exception when the number of tickets exceeds 400.

Step-by-step explanation:

The missing term in the code snippet provided would be the raise statement. In Python, when you want to trigger an error intentionally, you use the raise keyword followed by an instance of the exception class you wish to invoke. In your case, the correct implementation would be:

if tickets > 400:
raise over400error('Cannot process more than 400 tickets.')

This way, if the condition tickets > 400 evaluates to True, the over400error will be raised, stopping the execution of the program unless it is handled by an appropriate exception handling construct further in the code.
