> to introduce early stage students to Scheme before Python, or deep learning before calculus.

This book is part of the classic "Little" series of books starting with the "Little Schemer" which, despite its name and style, is certainly not a novice beginner book.

The later books: "Seasoned Schemer", "Reasoned Schemer", "The Little Typer" and "The Little Prover" are all very advanced books. They share the same style of illustrations and Socratic method, but you will absolutely need to work through them slowly and careful to get value out of them.

The "Little" books are generally targeted to an audience of computer language nerds and pretty much assume you have a solid understanding of programming, familiarity with scheme and the books come from a time when every serious engineer had basic calc knowledge.

These are classics (and I was really impressed with "The Little Learner") but are very serious and challenging texts, that outside the first book, are aimed at advanced readers (and for those readers are true delights).
