Countdown timer using Python

Introduction

In Python, a countdown timer is a program that counts down from a given time to zero. The user receives a signal when the countdown is complete, and it typically refreshes the remaining time every second.

Source Code:

import time 
            
def countdown(ti): 
                
    while ti: 
        mins, secs = divmod(ti, 60) 
        timer = '{:02d}:{:02d}'.format(mins, secs) 
        print(timer, end="\r") 
        time.sleep(1) 
        ti -= 1
                
    print("Time's up!") 
            
            
ti = input("Enter the time in seconds: ") 
            
countdown(int(ti))
