TypedDict, Dataclasses and Pydantic in action

Justinas Kuizinas

We're always using type hints in our code, but when working with microservices or when doing some integrations I started noticing that type hints alone are not enough to help us. In this presentation, I'll try to show my experience of how I moved and what benefits I got from using dict type hints to TypedDict, then to Dataclasses, and lastly to Pydantic. At the end of the day, it helped me to save a lot of time not only when implementing features, but also with the maintenance of already implemented parts of code.
