I'm looking for a way to emulate symlinks for Python imports. I'd like to be able to unzip the following folder structure in-place without duplicating files:

root
├─ python_lib
│  └─ my_utils
│     ├─ __init__.py
│     └─ etc.py
├─ app1
├─ app2
└─ app3
   ├─ lib
   │  ├─ __init__.py
   │  └─ my_utils.py
   └─ run.py

app3/run.py contains this:

from lib.my_utils import etc

etc.pancakes()

I'd like the code to use the etc located in python_lib/my_utils/. Is there anything I can put in app3/lib/my_utils.py so that Python >= 3.1 will transparently import the python_lib/my_utils/ folder (using relative paths and ..), and subpackages will also work?

python python-import
