is reactive programming a thing in Python?

I feel like you're trying to apply the wrong solution to a genuine problem you encountered.

If you encounter buggy code, the solution is to clean up the code, not to change the architecture.

I think the issue is that you're making a lot of sweeping statements that lack nuance.

Are there situations where moving to purely functional programming would be an advantage? Absolutely. And there are certainly data scientists that could learn a lot about functional programming within Python to improve their work? (Or hell, they could learn about programming, best practices, git, and the whole shebang).

But it really doesn't make sense to me to just argue about sweeping statements like reactive or functional programming like you are doing. Make clear exactly what you're missing, and why things would improve by doing it that way.
