I'm taking an online course and have to submit the code through a 3rd party grading system. I have all of the scripts working as intended locally but when I submit it to the online grader, I'm getting some confusing errors –– the grader is running my functions with its own inputs.
Here's one example:
Here's one example:
import datetime def days_in_month(year, month): """ Inputs: year - an integer between datetime.MINYEAR and datetime.MAXYEAR representing the year month - an integer between 1 and 12 representing the month Returns: The number of days in the input month. """ if (month < 1 or month > 12) or (year < 1 or year > 9999): return 0 first_of_month = datetime.date(year, month, 1) if month == 12: first_of_next_month = datetime.date(year + 1, 1, 1) else: first_of_next_month = datetime.date(year, month + 1, 1) difference = first_of_next_month - first_of_month return difference.days
Error:days_in_month(12, 12) expected 31 but received "(Exception: Returned Type Mismatch) Expected type 'int' but returned type 'NoneType'."
Appreciate any help -- thanks!
