What people are saying

PEP 695 is great. I've been using mypy every day at work in last couple years or so with very strict parameters (no any type etc) and I have experience writing real life…

> Came here to mention MyPy and optional typing, the preferable term Gradual Typing means something distinctly different. Are you sure that gradual typing is different than what Mypy supports? The Wikipedia page for gradual typing cites mypy as an example. https://en.wikipedia.org/wiki/Gradual_typing The Mypy docstrings specifically state: > Mypy has a powerful type system with features such as type inference, gradual typing, generics and union types. https://github.com/python/mypy/blob/272d0c4c50918a36b57e7c0c... The section on gradual typing in PEP 483 seems consistent with this as well. https://www.python.org/dev/peps/pep-0483/#summary-of-gradual...
