Python: Look What the Stork Dragged In

Well, this is supposed to be "a purely technical blog concerning topics such as Python, etc.", so let me start by showing off a quick little Python utility that I had to write at a moments notice:

#!/usr/bin/env python

"""Help Gina-Marie time her contractions."""

import time

SECS_PER_MIN = 60


last_start = None
while True:
    print "Press enter when the contraction starts.",
    raw_input()
    start = time.time()
    if last_start:
        print "It's been %s minutes %s seconds since last contraction." \
            % divmod(int(start - last_start), SECS_PER_MIN)
    last_start = start
    print "Press enter when the contraction stops.",
    raw_input()
    stop = time.time()
    print "Contraction lasted %s seconds." % int(stop - start)
    print
