Python Program to Measure the Elapsed Time in Python

Example 1: Using time module

import time

start = time.time()

print(23*2.3)

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

Output

52.9
3.600120544433594e-05

In order to calculate the time elapsed in executing a code, the time module can be used.

• Save the timestamp at the beginning of the code start using time()
• Save the timestamp at the end of the code end
• Find the difference between the end and start, which gives the execution time.

The execution time depends on the system.

Example 2: Using timeit module

from timeit import default_timer as timer

start = timer()

print(23*2.3)

end = timer()
print(end - start)

Output

52.9
6.355400000000039e-05

Similar to Example 1, we use timer() method from timeit module.

timeit provides the most accurate results.
