time.sleep() in Python

sleep() is defined in time() module of python 3 and python 2

Sometimes, there is a need to hault the flow of the program so that several other executions can take place or simply due to the utility required. sleep() can come handy in such a situation which provides an accurate and flexible way to hault the flow of code for any period of time. This function discusses the insight of this function.

Syntax : sleep(sec)

Parameters :
sec : Number of seconds for which the code is required to be stopped.

Returns : VOID.

# Python code to demonstrate
# working of sleep()
  
import time
  
# printing the start time 
print("The time of code execution begin is : ", end ="")
print(time.ctime())
  
# using sleep() to hault the code execution
time.sleep(6)
  
  
# printing the end time 
print("The time of code execution end is : ", end ="")
print(time.ctime())

Output:


The time of code execution begin is : Mon Apr  9 20:57:10 2018
The time of code execution end is : Mon Apr  9 20:57:16 2018





Application : 

There are many applications that sleep() is used for. Be it execution of the background thread which is repeated at regular interval, this can be implemented with the help of sleep(). Another popular application is using sleep() to print the words letter by letter for good user interface. The latter is represented from this code below.
