Relative importing modules from parent folder subfolder
import, module, python, python-2.7
Solution
The correct relative import would be this:
from ...common import foo
However, relative imports are only meant to work within one package. If `main` is a package, then you can use relative imports here. If `main` is not a package, you cannot.
Thus, if you're running a script in `/main/` and doing something like `import A.src.bar`, then that relative import will fail with "Attempted relative import beyond toplevel package". This is because the relative import is trying to import something outside of the toplevel package `A`.
However, if you're running a script in `/` and doing something like `import main.A.src.bar`, then that relative import will succeed because `main` is now a package. In that case, the following two would be equivalent:
from ...common import foo
from main.common import foo
To answer your comment: the meaning of the `.` doesn't change depending on where the script was run from, it changes depending on what the package structure is.
Problem
Given a directory structure like this ``` main/ common/ foo.py A/ src/ bar.py ``` How can I use Python's relative imports to import `foo` from `bar`? I've got a working solution by adding it to the path, but this is ugly. Is there a way to simply do with a single `import` in Python 2.7? This is a more complex version of this question: Importing modules from parent folder
