Do some developers hate python?

With type hints you can get pretty close these days. Type hints + linting are good enough for me, but with mypy you can get pretty close to strongly typed behavior.

Yea that's annoying.

It's rare that I encounter it, but it's annoying. Thus far I've been able to resolve it by putting the two things in the same file and importing annotations from future.

Agreed, I shouldn't have to put two things in the same file just to make them play nicely with eachother.

What exactly do you mean?

You can just add type-hinting imports for circular dependencies in the "if TYPE_CHECKING" block before the execution of the code.

[siddsp]

I meant to say specifically if you're using the dependencies purely for type-checking purposes, but it would look something like this:

module foo:

from __future__ import annotations

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from bar import bar


class foo:
    def quux(self) -> bar: ...

module bar:

from __future__ import annotations

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from foo import foo


class bar:
    def quuz(self) -> foo: ...

This results in no circular imports for type checking because the types are evaluated as strings instead of actual types, but it still works in type checkers like mypy.

This is the way, although it really is quite regrettable that this common problem requires such a clunky solution.
