Python Program to Measure the Elapsed Time in Python¶

In this example, you will learn to measure the elapsed time.

To understand this example, you should have the knowledge of the following Python programming topics:

Python time Module

In [3]:

# Example 1: Using time module

import time

start = time.time()

print(23*2.3)

end = time.time()
print(end - start)

'''
>>Expected output:
     
52.9
0.0
'''

52.9
0.0

Out[3]:

'\n>>Expected output:\n     \n52.9\n0.0\n'

The execution time depends on the system.

In [4]:

# Example 2: Using timeit module

from timeit import default_timer as timer

start = timer()

print(23*2.3)

end = timer()
print(end - start)


'''
>>Expected output:
     
52.9
0.00035429999996949846
'''

52.9
0.00035429999996949846

timeit provides the most accurate results.
