Cool python code that is a 10 minute timer

import time

def countdown_timer(duration):
    while duration > 0:
        mins, secs = divmod(duration, 60)
        timer_display = '{:02d}:{:02d}'.format(mins, secs)
        print(timer_display, end='\r')
        time.sleep(1)
        duration -= 1
    print("Timer complete!")

duration = 10 * 60  # 10 minutes
countdown_timer(duration)
