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?

    Bullshit!

    module/__init__.py:

    __all__ = ["foo", "bar"]

    module/foo.py:

    def foo():
    print("foo")

    module/bar.py:

    def bar():
    print("bar")

    module/baz.py:

    def baz():
    print("baz")

    main.py:

    from module import *
from module import baz

if __name__ == "__main__":
    print("main")
    foo.foo()
    bar.bar()
    baz.baz()

    Output:

    $ python main.py 
main
foo
bar
baz

    No errors, warnings or anything.
