I only recently learned myself that Jupyter notebooks do have code completion, triggered by hitting the tab button - although possibly you were thinking of something more advanced than that. In any case I'll check out your code on github.
Actually, if you activate the 'Hinterland' extension, you don't need to hit tab. And there's a ton of more extensions too. Their Github repo has instructions on how to set up the extensions - https://github.com/ipython-contrib/jupyter_contrib_nbextensi...
