Enhance ipynb support

[Betristor]

I'm using vscode for coding python for almost two years, and jupyter in vscode provides me much convience and fun while coding. But vscode has shortage in autocompletion especially in ipynb file for which I've searched so many extensions but nothing very handy shows. Kite shows me the probability but ipynb is not support by kite in vscode. I really hope this can be enhanced by either kite or vscode developers.
Much thanks!
