Case4. Given the month number is an integer in the range 1-12 (1 - January, 2 - February, etc.). Determine the number of days this month for a non-leap year.

Solution in Python 3:

import random

i = random.randrange(1,12)
print("Number of the month: ", i)
i = str(i)
m = {
    '1': 31,
    '2': 28,
    '3': 31,
    '4': 30,
    '5': 31,
    '6': 30,
    '7': 31,
    '8': 31,
    '9': 30,
    '10': 31,
    '11': 30,
    '12': 31
}
try:
    print(m[i])
except KeyError as e:
    print('Error')
