Create a Countdown Timer with Python

This blog will teach you how to make a countdown timer.

Python has a module named time to handle time-related tasks. To use functions defined in the module, we need to import the module first. Here's how:

import time

Here goes the full code for the CountDown Timer.

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 -= 1print("stop")

• The divmod() method takes two numbers and returns a tuple of their quotient and remainder

The syntax of divmod() is:

divmod(x, y)

divmod() Parameters

divmod() takes two parameters:

• x - a non-complex number (numerator)

• y - a non-complex number (denominator)

Return Value from divmod()

divmod() returns

• (q, r) - a pair of numbers (a tuple) consisting of quotient q and remainder r

If x and y are integers, the return value from divmod() is same as (a // b, x % y).

If either x or y is a float, the result is (q, x%y). Here, q is the whole part of the quotient.

• end='r' overwrites each iteration's output.

• The value of time sec is decremented at the end of each iteration.

 time.sleep() 

In the program, time.sleep() takes as arguments the number of seconds you want the program to halt or to be suspended before it moves forward to the next step.
