As others have mentioned, one can get some types in python through its own typing module and use a combination of tools for type enforcing and editor intellisense (mypy, pylance, etc.). However what I’m missing is having more advanced type constructs. For example mapped types, lookup types, etc [1]. That said, it seems like python devs keep adding features over time. For example a couple of years ago it wasn’t possible to specify which fields of a dictionary are required and not required (it required putting required fields in one TypedDict and then subclassing it into another one that had the non required ones with total=False), nor it was possible to “spread” a TypedDict to declare the kwarg types in a function.
