time sleep in Python

Question

What is the use of time.sleep() in Python?

Answer 1

Sleep function plays a very important role in a situation where we want to halt the program flow and let other executions happen. This function is defined in both versions of python i.e 2 and 3. It belongs to the time module of Python. It basically adds a delay to the execution and it will only pause the current thread and not the whole program. 

EXAMPLE:

import time # import time module

sleep_time = 1  # time to add delay after first print statement

print('Hello')

time.sleep(sleep_time)  # sleep time

print('Edureka!')

If the above code is executed it will add a delay in the program thus, the next statement will be executed after 1 second(s).
