The book is a very well written and rich introduction to scientific programming with Python. To be honest, the book could have been a bit more concise. But better too much than too less. It has to be mentioned that this book is not a introduction to Python! Even though the main concepts get a short review I would recommend it only to those you are familiar to the concepts of this programming language. If thats the case I can only recommend buying this book. And by the way: It really proofs much easier to do all the programming and computong on Linux since it is somewhat cumbersome to install all the required components on Windows, besides some features wont work on Windows!
