The question lists at least three frameworks that run Python in the browser.

[rbanffy]

None of which has anywhere near the traction of any JavaScript-based one, or has one comparable to any of the popular Python back-end frameworks.

Anyway, I think I didn't express myself properly - I used web framework for "backend web framework" the likes of Django or FastAPI.

Yeah - backend is all sorted with python and there's probably just enough basic level course coverage for back end web development concepts in Python. But thats useless if you want to make things people can actually see all by yourself.
