python pep8 class in init imported but not used

Question

I\'m doing PEP8 checks in python using the python flake8 library. I have an import statement in an __init__.py file in one of my sub-modules which looks like this:<

Answer 1

According to PEP 8, you should include MyClass in __all__, which will also fix the imported-but-not-used issue:

To better support introspection, modules should explicitly declare the names in their public API using the __all__ attribute.

Answer 2

According to flake8's documention, you can in-line ignore this specific warning with:

from .my_class import MyClass  # noqa: F401

For reference, here are flake8's error codes.

Answer 3

This is not actually a PEP8 violation. I simply do this:

from .my_class import MyClass  # noqa

Edit: Another possibility is to use __all__. In that case, flake8 understands what is going on:

from .my_class import MyClass

__all__ = ['MyClass',]
