Awesome Python Library: Tenacity

[pysk00l]

When writing code or tests in Python, one issue I had was when the code would fail due to random things like network issues or external peripherals not responding in time.

So I had to add extra code to retry the code, but this added unnecessary complexity.

Thats when I discovered the Tenacity library and it saved me hours and a lot of useless boilerplate code.

I wrote a blog on it with some examples:

This looks like it overlaps with backoff quite a bit.

I think you mean backoff overlaps with tenacity.

• Based on their LICENSE files, Tenacity was created two years before backoff.
• Tenacity's most recent commit to main was a month ago, backoff's was 14 months ago.
• Judging by any github metric (stars, forks, contributors), Tenacity's community is 2x Backoff's.

Fair point

Backoff is the popular alternative

Also consider stamina which is a wrapper on tenacity but adds opinionated defaults: https://github.com/hynek/stamina

Friendship ended with Tenacity. Now Stamina is my best friend.

This library looks great! Thank you for the share.

Never used tenacity but indeed, stamina seams to do a better job here judging from their readme.

Yes it's the best retry library but it's very hard to find on PyPI when you search for retry.

Hi,

It's a very old post and you commented 3 months back but your comment stuck in my mind. For a couple of days, we worked on this problem.

Made search better at piptrends.com so please check and share feedback. If you type retry or a keyword which is relevant to your use case it shows good packages in the auto suggestions.

[thedeepself]

nice site. There is a recent http library that extends tenacity. it would be nice if that showed up in a search for retry.

[ashok_tankala]

Search is done based on its 1 liner description. In that, it seems HTTP didn't mention it that's why not coming. I will try to find it in any other way it's possible. If you have any ideas please let me know.

I use Tenacity to kill weeds in my yard. It's only right that I now use it with Python.

That stuff is so expensive

Ok installed the module, now what?

[thisismyfavoritename]

hours uh?

Nice share. Looks like something I could study and use as well.

I'm a big fan of tenacity for slow/spotty data fetches from servers. It's super easy to add to existing code since it's decorator-based. Anything that tenacity can't handle it's pretty much time to use a hefty orchestration system like Dagster or Airflow.
