How do I add a custom python module to the Visual Studio IntelliSense code completion tool?
Situation: I am working on a python module that references another module that I have saved in /myPython/foo.py.
If I start to type foo.someDef I would like IntelliSense to recognize I am accessing that module and suggest a code completion.
Visual Studio's Intellisense will recognize custom Python modules after they have been properly placed in the "site-packages" folder under the "Lib" folder in Python's directory.
For example: /Python27/Lib/site-packages/myPython
Inside of the folder "myPython", put a plain text file called "__init__.py". Otherwise Intellisense will not recognize your package.
You may also have to click the "Refresh DB" under the Python Environments tab.
Hello, this is the new ai enabled intellicode plugin for VS 2017 (python). You can install it and test the result.

Turn intellisense database !OFF! by setting -> tools->options->python->experimental->!ON!
Now it works with the new ai-based intellicode.
There may be a short delay-time, which is ai-backend-communication-referred (https://prod.intellicode.vsengsaas.visualstudio.com/). But after a short time you get all intellicode informations - may be - perhaps it may last one day :) ). Repeat the dot several times if necessary.
