# Category Theory for python programmers

This is my attempt to implement some of the common structures from Category theory in python. Note that I am a beginner in Category theory and will use this repo as way to learn it.

Topics to be covered are

- [x] Monoids

- [ ] Functors (in progress)

- [ ] Applicative Functors (in progress)

- [ ] Monads

This list might be more detailed in the future.

My assessment is manly based on the book called [Category Theory for Programmers](https://bartoszmilewski.com/2014/10/28/category-theory-for-programmers-the-preface/) by Bartosz Milewski and the podcast [LambdaCast](https://soundcloud.com/lambda-cast)

## Typing

I will also use this platform to investigate some of the more advanced features of python's typing system, and will therefore only support the latest version of python.

## Testing

I am definitely not capable of finding good test cases that can really test the corner cases of my implementation. Therefore I will try to use (and learn) property-based testing using [Hypothesis](https://hypothesis.readthedocs.io/en/latest/).

## Contributing

This repo is manly for me to learn about these concepts in Category theory. If anyone finds this useful that is great. If you spot any bugs or mistakes I have made I would be grateful if you could file an issue (or even better : first file an issue and then submit a PR).
