How To Create a Countdown Timer Using Python?

Last Updated :09 May, 2025

In this article, we will see how to create a countdown timer using Python. The code will take input from the user regarding the length of the countdown in seconds. After that, a countdown will begin on the screen of the format 'minutes: seconds'. We will use the time module here.

Step-by-Step Approach

In this project, we will be using the time module and its sleep() function. Follow the below steps to create a countdown timer:

1. Import the time module using import time.

2.Get user input for countdown duration (in seconds).

3. Convert input to integer (as input() returns a string).

4. Define a function countdown(t) to perform the countdown.

5. Use a while loop to run the countdown until t reaches 0.

6. Inside the loop:

Usedivmod(t, 60) to convert seconds to minutes and seconds.
Format the time string using '{:02d}:{:02d}'.format(mins, secs).
Print the time on the same line usingend='\r' to overwrite the previous output.
Pause the loop for 1second usingtime.sleep(1).
Decreaset by1 eachiteration.

7. After the loop finishes, print "Fire in the hole!!" to indicate the timer has ended.

Python Code: Countdown Timer

Python

importtimedefcountdown(t):whilet:mins,secs=divmod(t,60)timer='{:02d}:{:02d}'.format(mins,secs)print(timer,end='\r')# Overwrite the line each secondtime.sleep(1)t-=1print("Fire in the hole!!")t=input("Enter the time in seconds: ")countdown(int(t))

Output:
