Writing Python like it’s Rust

1. cattrs

   1 10 1,036 8.1 Python

   Composable custom class converters for attrs, dataclasses and friends.

   

   I'd suggest you look at my cattrs (https://catt.rs) library as a good serde lookalike in Python (sum type support present and getting better), and to use attrs instead of dataclasses in general.

3. plum

   2 6 643 8.6 Python

   Multiple dispatch in Python

   

   You can use https://github.com/beartype/plum instead of that elif chain too

4. jaxtyping

   3 10 1,817 7.7 Python

   Type annotations and runtime checking for shape and dtype of JAX/NumPy/PyTorch/etc. arrays. https://docs.kidger.site/jaxtyping/

   

   Since you mention ML use-cases, you might like jaxtyping.

5. equinox

   4 33 2,896 8.6 Python

   Elegant easy-to-use neural networks + scientific computing in JAX. https://docs.kidger.site/equinox/

   

   I'm a big fan of using ABCs to declare interfaces -- so much so that I have an improved abc.ABCMeta that also handles abstract instance variables and abstract class variables: https://github.com/patrick-kidger/equinox/blob/main/equinox/_better_abstract.py
