Python has a "we're all adults here" mindset, which means it will allow you to reach into internals of libraries, ignore type hints, etc because maybe you actually know what you're doing and know the drawbacks but just need a quick solution (lots of python code is small throwaway scripts). For actual projects you can use a static type checker like mypy.
