I intend to create notebooks that other users with little coding experience should be able to run themselves. After discussion with @yuvipanda at Wikimania one possible solution would be to make the notebooks fork-able. Since the intended audience is beginners in coding it would prefereably be a nice friendly button saying e.g. "Copy" or "Fork" in the view of the actual notebook.
!wget http://paws-public.wmflabs.org/paws-public/44645351/wikibot.py?format=raw > wikibot.py
Will work from notebook itself, fwiw.
I'll look into making a more user-friendly version of this.
