2 days ago · The typing module provides a vocabulary of more advanced type hints. New features are frequently added to the typing module. The typing_extensions package provides backports of these new features to older versions of Python.

Apr 8, 2017 · With dependent types you can write a spec (logic/relational / constraint programming) of what you want your function to do and it can auto-complete the complete definition for you using an SMT solver (Refinement Types).

Feb 14, 2024 · By creatively using type annotations and the typing module, you can enforce more stringent type checks and emulate dependent typing patterns, leading to safer and more predictable code. This tutorial has only scratched the surface; the possibilities are as vast as your creativity allows.

Nov 3, 2019 · def fun(A_type: Type[A]) -> A: if A_type == A1: return A1() else: return A2() a1: A1 = fun(A1) This precisely describes the typing for the two variants. As both an upside and downside of this approach, you'll have to explicitly add another overload for every inheriting class you want to support.

I am dynamically loading a Python module using importlib.import_module as follows def load_module(mod_name: str) -> ???: return importlib.import_module(mod_name) Can somebody tell me what is the correct type annotation for a module type.
