Create a Countdown Clock

When clock completes its countdown, start the video!

import time
import sys
import webbrowser

def countdown(secs):
    while secs:
        mx, sx = divmod(secs, 60)
        timeformat = '{:02d}:{:02d}\r'.format(mx, sx)
        print timeformat,
        sys.stdout.flush()
        time.sleep(1)
        secs -= 1

countdown(2 * 3 * 2)
webbrowser.open("http://www.youtube.com/watch?v=dQw4w9WgXcQ")
