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:

Example 1: Using time module

import time

# Save timestamp
start = time.time()

print(23*2.3)

# Save timestamp
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 the time() function.
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.

Note: The time.time() function from the time module returns the current time in seconds.

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 the timer() method from the timeit module.

timeit provides the most accurate results.

Note: The timer() function also returns the current time in seconds.
