Install the Python extension by Don Jayamanne.
In settings.json override the built-in Jedi by setting "python.jediPath": "/usr/lib/python3.5/site-packages".
Test the "IntelliSense" (autocomplete) feature.

I'll try to find time to test with GNOME Builder later today.

Tested with gnome-builder. Thought it was working, but it's showing jedi not found when run from terminal. Investigating now.

Tracking upstream issue for GNOME Builder with jedi>=0.10.0 here. Might attempt a patch.

@JoshStrobl, this is required for python3 IPython, which I've successfully packaged (D709). The GNOME Builder upstream issue might take a while to resolve (it was reported in February), so is it OK for you to commit this just now? It fails silently so has little impact other than the lost completion functionality. I have also packaged pylint (D646) which works in GNOME Builder when gnome-code-assistance is installed (D711), so you could swap the lost functionality for new functionality?

@JoshStrobl, someone from Fedora patched GNOME Builder to work with the newer jedi. I've applied the patch (D711) and verified jedi is now working as intended. This update should be all ready to go now!
