In short, the book is really great for beginners. Because it does not linger as a technology, but retraces the entire panel technologies involved in web development (HTML, CSS, Python, Ajax, etc.). Everything is explained and introduced very gradually, based on concrete examples.
Very interesting for beginners who do not know where to start a web development. There's even a chapter that explains the minimum analysis and tracking to follow before plunging body and soul in the code.

Positit extra point, the book is contains some touches of humor, which makes her very pleasant reading.

We also see that the authors are from universities because they do not derogate from some explanations and theoretical concepts to provide a more remote vision and put into perspective the concepts put works. It is not superfluous.

Recommended!
