This is the textbook used for the introductory CS course (CS61A) at UC Berkeley. The course material is available at http://cs61a.org/fa18 (The course uses Python 3, Scheme, and SQL).
There are some neat projects (students build a Scheme interpreter and implement game logic as part of the projects)

Thanks for linking this, I'm currently working on designing an introductory python course. What background are students expected to have for CS61A? Is it expected to be students first introduction to python?
