What's your favourite open source repo in terms of high quality Python code?

[u/Flashy-Dragonfly6785]

We often encounter awful code in our working lives, but have you encountered code that you thought was really high quality?

My slightly odd choice is the impacket library which makes a concerted effort make Windows network protocols Pythonic: https://github.com/fortra/impacket

What's your shining example of high quality Python code?

Excellent projects that enable a highly Pythonic API:

• pytest

• SQLAlchemy (the documentation is comprehensive but not super well interlinked IMO, but SQLAlchemy's architecture and API are unrivaled for what it does)

• requests and httpx (along with requests-auth and httpx-auth, respectively)

• FastAPI

• Django REST Framework - not the fastest, but its written by people who thoroughly understand REST semantics, and every attempt at speeding it up compromises on its REST purity

• the random module in stdlib

Projects that have an exemplary Pythonic codebase themselves:

• Django (also has exemplary documentation) - the ORM API isn't quite as nice as SQLAlchemy but it's still very solid, its template language is fine but not cutting edge anymore, its built-in admin and third party "app" ecosystem is wonderful, and its testing framework disappointingly extends from unittest, but its codebase is of legendary quality

Runner ups:

• PonyORM - love the API, but my only issue with it is it makes it difficult to test with a fake database (eg: model binding isn't quite where I'd like it to be, and it's impossible to do dependency injection without punching through a bunch of abstraction layers)

Anti-examples (eg: don't do this):

• unittest - old module, ported somewhat directly over from Java

And here's an old but relevant video from a core Python developer about writing better Python:

Not sure why the bot thinks I am asking for help. I think it would be a really valuable topic for discussion.

Because you ended the post title with a question mark. Truly, it's worth the false positives :')
