Question

I Have following directory structure:

src
   __init__.py
   foo1
       __init__.py
      foo1.py
   foo2
     __init__.py
     foo2.py

Now I want to import from foo2.py the module foo1.py. In foo2.py I’ve imported with from ..foo1.foo1 import * but all I get is:

Traceback (most recent call last):
  File "foo2.py", line 3, in <module>
    from ..foo1.foo1 import *
ValueError: Attempted relative import in non-package

How do I get this relative import?

Answer 1

What I see here is that the base package, in your case src has not been imported, this is a necessary condition to use relative imports.

If you write an script that the src folder is in the sys.path, thus importable, which states:

import src #this imports the base package
from src.foo2.foo2 import *

...

It will work.
