cs50/problems/2022/python/working: check50 doesn’t reject single-digit minutes (e.g., "10:7 AM to 5 PM") #388
Description
Summary
Raising this to help improve the autograder tests for future students.
For cs50/problems/2022/python/working, check50 currently accepts an implementation of convert that allows single-digit minutes (e.g., "10:7 AM to 5 PM"), even though the spec states that minutes must be exactly two digits when provided in HH:MM form.
Minimal example / behavior
My current implementation passes all check50 tests:
$ check50 cs50/problems/2022/python/working
# ... all tests reported as passing ...The program accepts an input with single-digit minutes (10:7 AM).
It does not raise ValueError.
It simply prints 10:7 to 17:00.
Given that this implementation passes check50, it appears that there is no test that verifies the requirement that minutes be two digits when present.
Expected vs actual behavior
Expected (per spec):
Inputs like "10:7 AM to 5 PM" should be considered invalid and cause convert to raise ValueError, because minutes in HH:MM must be two digits.
Actual:
An implementation that accepts "10:7 AM to 5 PM" and outputs "10:7 to 17:00" still passes check50 cs50/problems/2022/python/working.
