If the Ruby tutorial is any indication, Michael's book will be the best when it comes out. Never gone through any Python tutorials but I've heard good things about: http://www.djangobook.com/en/2.0/index.html, and https://www.twoscoopspress.com/. Take the recommendation with a pinch of salt because I've never done them myself.
Given that Michael's book is 90% about using Rails, I understood the asker's question to be related to using the framework more so than the language itself.
