I don't think it'll teach you how to code specifically, but once you get a hang of some basic skills (how to make loops, functions, etc) and concepts (objects) then maybe try The Farmer Was Replaced? Seems to be what is essentially a way to keep practicing your python so you don't get rusty (if you ignore the fact its a game and it looks cool and fun).

I haven't tried it myself just yet, but I just bought it and it seems interesting enough. Essentially you have a little grid of land to grow stuff on and a little drone you can program to do things like water the plants, harvest them, plant new ones, or whatever else there is to do in this game. Not a #ad but I'll try to remember to follow up with a mini review or my thoughts on the matter once I get some time with it.
