ACCEPTED ANSWER

Score 31

You can achieve this without regular expressions:

import time

def isTimeFormat(input):
    try:
        time.strptime(input, '%H:%M')
        return True
    except ValueError:
        return False

>>>isTimeFormat('12:12')
True

>>>isTimeFormat('012:12')
False

ANSWER 2

Score 7

import re

time_re = re.compile(r'^(([01]\d|2[0-3]):([0-5]\d)|24:00)$')
def is_time_format(s):
    return bool(time_re.match(s))

Matches everything from 00:00 to 24:00.

This will give you the regexp object which will check it. However, depending on who you ask 24:00 might not be a valid time (it's 00:00). But I guess this is easy to modify to suit your needs.

import re
regexp = re.compile("(24:00|2[0-3]:[0-5][0-9]|[0-1][0-9]:[0-5][0-9])")
