What’s the newest Python Comp. Sci. Textbook?

A Computer Science textbook that uses Python as its core language was released, I believe, this year. However, I CAN’T FIND IT! I searched google, amazon, bn.com, and used all the terms you’d normally think of using, and I can’t find this book anywhere. The book is black, and has a picture of a snake’s head on it. Can anyone help me out with finding this book?
