Bug report

from typing import Any

class Foo(Any): ...

print(repr(Foo))  # => typing.Any not <class '__main__.Foo'> as I would expect

I believe

cpython/Lib/typing.py

Lines 495 to 496 in e8259e0

def __repr__(self):
return "typing.Any"
needs to be changed to

        def __repr__(self):
            if self is Any:
                return "typing.Any"
            return super().__repr__()

Your environment

  • CPython versions tested on: 3.11 and 3.12
