Try the following (it's made in python2):

import time, sys

def countdown(totalTime):
    try:
        while totalTime >= 0:
            mins, secs = divmod(totalTime, 60)
            sys.stdout.write("\rWaiting for {:02d}:{:02d}  minutes...".format(mins, secs))
            sys.stdout.flush()
            time.sleep(1)
            totalTime -= 1
            if totalTime <= -1:
                print "\n"
                break
    except KeyboardInterrupt:
        exit("\n^C Detected!\nExiting...")

Call it like this: countdown(time) For example: countdown(600) for 10 minutes.
