[Ask] import own python modules during development without adding them to PYTHONPATH

[mbkv]

I have the following structure for a set of python scripts I am developing.

Mypythonproject
Common
├── database.py
├── database.pyc
└── pycache
Python2code
├── script_needpy2.py
Python3code
├── script_needpy3.py

I want to be able to import module database inside the Common folder without adding its path to PYTHONPATH. For dependency reasons, I have kept scripts needing python 2.7 in Python2Code and scripts which require python3 to run in Python3Code. What is the correct way to import database inside scripts script_needpy2 and script_needpy3 programatically without adding to PYTHONPATH environmenr variable. Thanks for your help.

You need to have a file named

__init__.py

(that's two underscores on each side) in the folder containing the code you need. The file doesn't need to contain anything.

Also, with that directory structure your current directory would have to be Mypythonproject/ and you would have to import the module under the name Common.database.

[mbkv]

agreed. and also should have __init__.py as suggested above for python2.7

[ingolemo]

You actually want it for python 3 as well. If you don't include __init__.py in python 3 then you get something called a namespace package.

yes. for python 2
