Rust's Option and Result. In Python.
Not to diminish this at all, but https://github.com/dry-python/returns also exists. The scope is wider, but the look and feel of the types feels very similar.

Python errors as values: Comparing useful patterns from Rust and Go
The result package in the article: https://github.com/rustedpy/result
There's a pretty decent explanation in the readme. If you're more interested in Monads, I am not sure I'd cover that in a HN comment very well, but I would encourage you to take a look.

Rust-like error handling in Python with NamedTuple
Use the result package, if you want a proper, rusty result type. This approach is bad.
