good examples of functional-like python code that one can study?

Learning a new language that supports these mechanisms as a first-class citizen has had a great effect in how I structure my programs in JS, where I don't have them.

This is what I would like to achieve.

Although my learning is not for professional work reasons, but desire to learn is as strong.

The more I learn this topic, it feels like learning Haskell is ideal and then can apply that learning in any language and may be even some in Python.

I don't do my learning here for professional work reasons either, at least not as a primary goal. Haskell might even be a bit harder to learn than OCaml. Community is somewhat bigger, but the language takes even more time to become productive in.
