Exercise: Checking a List of Problems
Description
In this exercise, your code will check a list
of answers to see how many are correct for a list
of problems.
File
quiz.py
Function Name
• check_problems()
Parameters
• problems : a list of
problems
• answers : a list of
numbers
Action
This function will count the number of correct answers
in the list. The lengths of problems and answers will
be the same. The first answer is for the first problem,
and so forth.
Return Value
A number, the number of answers that were correct.
Examples
problems = [ AdditionProblem(1, 3), MultiplicationProblem(2, 3)
]
answers = [ 4, 5 ]
check_problems(problems, answers) -> 1
