Others have dealt with the specifics.
If you really want to learn how to use and write recursive code there is
(IMHO!) no better place to go than the online book How To Design
Programs. It's written using Scheme but the code is clear enough that
you should translate to Python easily. You probably only need to read
the first 4 chapters or so. The author builds up a set of heuristics for
defining recursive solutions - i.e. writing functions!
