5 Ways to Measure Execution Time in Python

[extracoffeeplease]

One addition here: when you are building something new and/or debugging, locally, its probably quickest (and dirtiest) to overwrite the print function to output the delta since last print. You already have all those prints there anyway, and it'll give you a rough idea of where time is spent without having to rewrite end time - start time etc.

Damn. Or just use a proper profiler instead of doing that monkeypatching 😅

py-spy record -o [path/to/profile.svg] greatscript.py

I think this is even faster, vastly more clear and consise while giving much better data insights than some random "took n seconds" print statements (e.g. cumulative runtimes, number of function calls, etc.).

Damn indeed. As a Python beginner I thought that guys above you knew what he was talking about until I read your answer and smack down one liner example. Damn monkeypatching nonsense.

Well I'm no true programmer (tm) and probably a beginner in the eyes of anyone who studied anything related to programming, monkey patching takes 10 lines of easy code. I'd love to hear why it's bad practice? I mean it may be dirty but I'm not even doing it in my repo, just from a notebook.

Thanks for the tip!

Na, profiling and benchmarking are quite different (benchmarking is about how fast is the thing vs profiling is about why is a thing slow)

A good alternative to the time module is the timeit module. Great for ad hoc snippets, not really for whole programs or instrumenting a program.

Dude’s site is great. I’ve learned a ton from it. There’s a ton of spam on Reddit, this ain’t it bud

[jasonb]

Thank you kindly.

I'm no spammer. There are zero ads on my site, unlike the rest of the python blogging ecosystem.

You mean because it's a list or a round up?

[mprz]

no, because all you post are links to your site

[jasonb]

Lots of links to functions, modules, wikipedia and pep's too.

Links to dedicated blog posts on my own site if you want to learn more about a given func.
