How to Create a Python Countdown Timer?

Estimated read time 1 min read

To create a Python countdown timer, you can use the time module and a loop that decrements a counter until it reaches 0. Here’s an example:

import time

seconds = 10

while seconds > 0:
    seconds -= 1

print("Time's up!")

In this example, we define a variable seconds that represents the duration of the countdown in seconds. We use a while loop to repeatedly print the remaining number of seconds and wait for 1 second using the time.sleep() function. We also decrement the seconds variable by 1 in each iteration of the loop.

When the seconds variable reaches 0, the loop terminates and the final message is printed.

You can modify this example to perform some action when the countdown reaches 0, such as playing a sound or sending a notification.
