How to Use Sleep Function in Python

Python comes pre-built with time module. It provides sleep function which has the following syntax.

time.sleep(seconds)

In the above function, you need to provide the number of seconds you want to pause execution in python.

Here is an example to pause execution for 3 seconds.

import time
print("hello")
time.sleep(3)
print("world")

You can also use it in a python function as shown below.

import time

def hello_world():
   print("Hello")
   time.sleep(3)
   print("World")

When you run the above function, you will see that it prints ‘world’ only 3 seconds after it prints ‘hello’ indicating that the execution was paused for 3 seconds.

You can use sleep function in any python function or code that is to be executed, as long as you import time module in it.
