Benchmark code with the with statement (Python)

2011-10-10T04:30:11-07:00

Python recipe 577900 by vleon (benchmark, speed, time, timer).

Inspired by this post I wrote this context manager to benchmark code blocks or function calls.

Usage is incredibly simple:

with Timer():
    ...  # code to benchmark goes here

The time taken (in seconds) will be printed when the code block completes. To capture the time taken programmatically is almost as easy:

t = Timer()
with t:
    ...  # code to benchmark goes here
time_taken = t.interval

Due to the difficulties of timing small snippets of code accurately, you should only use this for timing code blocks or function calls which take a significant amount of time to process. For micro-benchmarks, you should use the timeit module.

General purpose technique for counting comparisons in various searching and sorting applications.

A simple function benchmarking module (Python)

Python recipe 577377 by Timothee Cezard (benchmark, debugging, function).

This module enable its user to monitor the amount of time spend in between two commands start and stop. The module is fairly imprecise if the monitored task is quick as the start and stop commands are fairly slow (2e-07 - 5e-07 second)
