Python method of calculating the running time of a program

This example demonstrates how Python calculates the running time of a program. Share with you for your reference. The specific implementation method is as follows:

import time
def start_sleep():

    time.sleep(3)
if __name__ == '__main__':

    #The start time 

    start = time.clock()
    #A program which will run for 3 seconds

    start_sleep()
    #The End time 

    end = time.clock()
    print("The function run time is : %.03f seconds" %(end-start))
    # End
