This article aims to show how to measure the time taken by the program to execute. Calculating time helps to optimize your Python script to perform better.
Approach #1 :
A simple solution to it is to use time module to get the current time. The following steps calculate the running time of a program or section of a program.
- Store the starting time before the first line of the program executes.
- Store the ending time after the last line of the program executes.
- Print the difference between start time and end time.
Code #1 :
# Code to Measure time taken by program to execute. import time # store starting time begin = time.time() # program body starts for i in range ( 5 ): print ( "GeeksForGeeks" ) # program body ends time.sleep( 1 ) # store end time end = time.time() # total time taken print (f "Total runtime of the program is {end - begin}" ) |
GeeksForGeeks GeeksForGeeks GeeksForGeeks GeeksForGeeks GeeksForGeeks Total runtime of the program is 1.0010437965393066
Approach #2 : Using Timeit
module
# importing the required module import timeit # code snippet to be executed only once mysetup = "from math import sqrt" # code snippet whose execution time is to be measured mycode = ''' def example(): mylist = [] for x in range(100): mylist.append(sqrt(x)) ''' # timeit statement print timeit.timeit(setup = mysetup, stmt = mycode, number = 10000 ) |
Output:
0.00119590759277
Note: Output may vary depending on the system or server load.
