Talks: Getting Started with Statically Typed Programming in Python 3.10

Presented by:


Since 2015, it has been possible to write Python like a statically typed language with typing modules and other features introduced in Python 3.5.

This can significantly improve the development experience and review process.

I have been using type hints in my work for several years and have been studying Haskell and TypeScirpt. I believe this session will be a stepping stone for "type hints newbies."
