I agree. This book taught me stacks, queues, deques, trees, and graphs. I was already exposed to searching/sorting and recursion from other resources, including John Zelle's "Python Programming: An Introduction to Computer Science" (2nd edition), which I recommend to any beginning Python programmer as a prelude to this one. It's perfect for self-teaching. Contact the publisher (same one, actually) for exercise answers and work through them all. I even emailed the author for a clarification and he responded with a thorough answer. Overall, a great learning experience that took my programming knowledge and skills to the next level.
