Data Structures and Algorithms in Python

I've been reading this book for 4 years now. Usually, Algorithm books are not the type of book that you read from front-to-back in one seat. It works more like a reference book. You are curious about Binary Search Tree, you get the chapter, read the theory, understand the concepts, and try to implement it. The book has all this experience, from theory and concepts to Python implementations and exercises to practice. I'm not sure if the authors use the Python best practices or clean code. Some bits are just difficult to understand.
