flake8-all-not-strings

Flake8 plugin that checks that the all the elements defined in the __all__ list are strings. Sometimes the flake8 doesn't throw error from the __init__.py if the modules under __all__ are not strings.

Example below of an __init__.py file which should throw an error:-

from some_module import some_function 
__all__ = [
      some_function
]

Example below of an __init__.py file which should not throw an error:-

from some_module import some_function 
__all__ = [
      'some_function'
]
