Google's Python class is a pretty good start[0]. It's enough to get you started and moves at a nice pace! After that I'd hack on a project of my own. Even better if you have a project in mind before learning the language. This book by Jeff Knup will get you familiar with the pythonic way of doing things[1].
I would advise against Google's python course, as it is geared toward python devs working at Google. The course teaches Python 2, and goes against widely accepted guidelines such as PEP-8.
I highly recommend David Beazley's Python Cookbook (https://www.dabeaz.com/cookbook.html) for the most idiomatic and comprehensive introduction to Python.
