CS for All: An Introduction to Computer Science Using Python
Alvarado, Christine, Dodds, Zachary, Kuenning, Geoff
Here's a unique approach to "Intro CS." In a nutshell, this book's objective is to provide an introduction to computer science as an intellectually rich and vibrant field rather than focusing exclusively on computer programming. While programming is certainly an important and pervasive element of their approach, this book emphasizes concepts and problem-solving over syntax and programming language features.
