2013-11-24 Sunday - Book Review: Python In Practice



I recently had an opportunity to read Python in Practice, by Mark Summerfield as a reviewer for Pearson Education.

Two noteworthy points:
- The code samples are based on Python 3.x
- The author's web site provides sample code download

The very first thing I noticed about this book is that the sample bits of code are very concise - without extraneous fluff.

This book is an excellent addition to any software craftsman's library that needs a quick dive into practical hands-on Python coding.  Each page has a feeling of being written from the perspective of someone who has lived in the trenches producing production-quality python code for over a decade. This book has the feeling of a friendly mentor's guiding hand.

To help you understand the impression that this book left in my mind, let me share another word that arose unbidden in my mind as I made my way through the pages of this book: In Japanese, the phrase "Sensei" is often translated as "teacher", but also has a literal meaning of "One Who Has Gone Before". Mark's transmission of his depth of experience to the printed word is given in that same spirit of a Sensei teaching lessons gleaned from years of practice.

Another unexpected pleasure discovered within the pages of Mark's book: An emphasis on patterns. The first three chapters provide an excellent overview of the python-esque approach to implementing the various patterns that were described in the book Design Patterns: Elements of Reusable Object-Oriented Software.

I also found Chapter 5. Extending Python to be very interesting for focusing the discussion on Python's ctypes and Cython - techniques which are often needed to solve high performance problems.

One minor criticism is the author's choice in focusing on XML-RPC style in Chapter 6. High Level Networking [versus RESTful web service based integration strategies]
