Full Review 

Reviewer: Mike James  Rating: 3 out of 5
Verdict: The book is well written, but it’s not Python Pro material. If you are a self-taught novice you might find this exposition of the standard ideas of object-oriented programming useful and interesting but be warned Python has many important and powerful features that are simply ignored in this account.
