Compare if datetime.timedelta is between two values

I have a datetime.timedelta time object in python (e.g. 00:02:00) I want to check if this time is less than 5 minutes and greater then 1 minute.

I'm not sure how to construct a timedelta object and I'm also not sure if this is the right format to compare times. Would anyone know the most efficient way to do this?

So if you start with a string that's rigorously and precisely in the format 'HH:MM:SS', timedelta doesn't directly offer a string-parsing function, but it's not hard to make one:

import datetime

def parsedelta(hhmmss):
    h, m, s = hhmmss.split(':')
    return datetime.timedelta(hours=int(h), minutes=int(m), seconds=int(s))

If you need to parse many different variants you'll be better off looking for third-party packages like dateutil.

Once you do have timedelta instance, the check you request is easy, e.g:

onemin = datetime.timedelta(minutes=1)
fivemin = datetime.timedelta(minutes=5)

if onemin < parsedelta('00:02:00') < fivemin:
    print('yep')

will, as expected, display yep.
