@mthrok we have two options according to

from .my_class import MyClass

__all__ = ['MyClass',]

or

from .my_class import MyClass  # noqa: F401

Confirming that the first option was preferred right?

Hi @krishnakalyan3

Thanks for the follow up. Yes, the __all__ is the preferred approach for public APIs, but for internal APIs, noqa is preferred. So, for backend module, let's use noqa.

@mthrok yes.

Thanks!
