### What was wrong?

I'm using web3py to interact with a deployed contract. Instead of calling the functions by-hand and using error-prone strings, I would like to use auto-generated contract methods (similar to what Typechain (https://github.com/dethcrypto/TypeChain) does in Typescript.

Is there support for typings and/or autogeneration in web3py? If not, is there a package that achieves this?

Thank you!
