 Create a Countdown time in Python

In this example, we will create a countdown timer in python. The program will ask the user to input time. Then the program will set the countdown from that time given by the user. To understand this program you should have basic knowledge of - 

1. Modules in Python
2. Defining a function
3. While loop in Python

Code:

import time

def countdown(time_sec):
    while time_sec:
        mins, secs = divmod(time_sec, 60)
        timeformat = '{:02d}:{:02d}'.format(mins, secs)
        print(timeformat, end='\r')
        time.sleep(1)
        time_sec -= 1

    print("stop")

timer = int(input("Enter countdown: "))
countdown(timer)
