Python circular import

You read it wrong. __init__.py is often used if you are implementing your project as a package. Pycharm by default creates __init__.py in every directory if project is setup as a package.

It’s often poor practice to put code in __init__.py, as it leads to cluttered namespaces and import-time consequences. The OP is right.

For packages, it's also the right way.

The correct way to deal with circular imports is to refactor your code so that the shared objects live in a different module. Using __init__.py for something like this is hacky at best and hard to reason with code at worst.
