How to add pause delay in python using sleep function

In this tutorial we are going to learn how to pause python script using time.sleep() function.

Often you will need to add a delay to python scripts, which means you pause the execution of the python script for the number of seconds before executing the next line of codes.

We can add delay to python script using time module. The sleep() function of the time module pauses your python program for the specified number of seconds.

import time

time.sleep(n) # n = number of seconds for wait

Example 1

import time

print("Hello World 1")
time.sleep(10) # pause python script for 10 seconds
print("Hello World 2")

As per the above example, first we print the “Hello World 1” then we pause the python script for 10 second (Add 10 second delay). After 10 seconds it will print the “Hello World 2”.

Example 2 – Open web browser after delay

import time
import webbrowser

print("Waiting for 5 minutes")

In the above example, first we print the message “Waiting for 5 minutes”, Then we pause the python script for 5 minutes (300 seconds). After 5 minutes of delay it will open the web browser with the URL https://www.python.org/.

So that is how we can pause and add delay in python 3 using time.sleep() function.
