Python is used a lot for algorithmic trading.

For super basic data science stuff after Machine Learning I'd recommend this book if you've never come across the prediction algorithms before.

I think this connection should exist.

If you plan on using machine learning stuff then you're probably better off starting with Hands-On Machine Learning.

To cover Python programing as well as machine learning in one book the A.I. Investor goes over everything very quickly with few pages used for each subject. For a proper introduction to Python the Python Crash Course book is a much better guide.

For general learning about Python, Python crash course is a great book.

Python knowledge is assumed, so for beginners you can't go wrong with the Python Crash Course.

To cover Python well it's a good idea to have a dedicated book for it, there's only so much that Google can help you with. Python Crash Course is great for that.

For Python programming generally, inc. how to start it up and make it run code and best practices etc. the Crash Course book is good.
