Question

Is there a more elegant way to validate the month input for this Zeller's Algorithm program? I've done the exercise (Opt. 1 in week 2 for #MOOC) and it works, but I wonder if there's a more elegant way to validate the input. It should check that you've entered a real month. I did:
while month != 'march' and month != 'april' etc.

Answer 1

Put all valid months in a list and check if the input exists in the list (or is member of the list)

Answer 2

This might save you some typing:

import calendar
while month not in calendar.month_name:
# ask for another month
