Python relative imports

Question

Right, I have a structure like so:

/Project
    __init__.py
    script_a.py
    /tests
        __init__.py
        test_something.py

When test_something tries to import using from . import script_a from . import script_a it returns the error Attempted relative import in non-package .

I've put in the empty __init__.py files and added /Project to PYTHONPATH but it still throws up this error!

Any ideas?

EDIT: I have now used a tester.py situated in \\Project and call:

import script_a
from tests.test_something import *

Now it works!!

Answer 1

from Project import script_a应该适合你。

Answer 2

When test_something tries to import using from . import script_a from . import script_a it returns the error Attempted relative import in non-package .

1. Using one dot . will lead you to the current directory. You should use two dots .. to get to the parent dir.

2. You cannot run a module with a relative import itself. You can only import it. So test_something.py can only run as an import but it is not possible to run the script as __main__
