I am a bit confused as well and I think I was not born to write manuals. I can and will help you for sure 
especially since we gone this long way and many things are already working.
The only thing I can't help you with is the problem with pip/ spotipy, sorry for confusing you... and I think you have to use google for solving this. If spotipy is installed we can go further and get things working.
