This week's book giveaways are in the Cloud and AI/ML forums. We're giving away four copies each of Cloud Native Patterns and Natural Language Processing and have the authors on-line! See this thread and this one for details.
Caveat: I learned Python almost 20 years ago, haven't used it in 5 (I retired), and missed the whole Python 3 debacle.
Best book I found was a Python Cookbook. It presents a bunch of small problems and solves them in Python. Python itself is pretty easy to pick up but, like most languages, it can be hard to do things "the Python way". This book showed how to think like a snake.
Oblig: Guido messed up when he used whitespace as block delimiters. Should have used curly braces or somesuch. YMMV.
