This book gets overlooked in favor of other ones such as Python Crash Course but I really enjoyed reading through Think Python 2e and will read through this version as well. Check out the rest of his books on Green Tea Press.
Python Crash Course teaches Python while Think Python teachers computer science using Python. You are right that they are two different books but people recommend Python Crash Course for beginners when Think Python is a much better recommendation for them in opinion. If you just need to learn Python then PCC is a great book.
