Let’s say I have the following structure:
my_module/
__init__.py
utilities.py
and __init__.py contains
from .utilities import SomeUtilityFunction
Is there a way to prevent or alert developers when they do
from my_module.utilities import SomeUtilityFunction
instead of
from my_module import SomeUtilityFunction
The problem arose when a few modules started using a function that was imported inside a module in which it wasn’t used, while also being available on the module’s __init__.py, so after linting the file and removing the unused import my tests started failing.
any other advice for situations like this?
@fixmycode mypy type checking can report this error in your code:
iox3.py:3: error: Module “iox2” does not explicitly export attribute “y” [attr-defined]
which I think is roughly the problem you are encountering: an attribute in an imported module that wasn’t explicitly defined in that module, but instead came from somewhere else.
I think this is the more sensitive approach, I’ll take a look at putting mypy in my pipeline
