Import Packages from different local folder without sys.path

Question

I have a directory structure like:

proj/
 |- src/
   |- org/
     |- example/
       |- dir/
         |- foo.py
         |- ...
 |- src2/
   |- org/
     |- example/
       |- dir/
         |- bar.py
         |- ...

My question is: How to import foo into bar without using sys.path and, if possible, avoid writing a __init__.py file in every subdirectory of src ? Note that the actual .py files are located in the dir folders only if it's relevant.

Answer 1

from src.org.example.dir import foo
