Python module and __all__

Question

I trying to understand how to manage module with __all. For example, I have following structured code:

main.py
|=> /database
    |=> __ini         


        

Answer 1

Listing names in __all__ does not, by itself, import items into a module. All it does is list names to import from that module if you used from database import * syntax.

Import session into database/__init__.py:

from .engine import session
