The programming principals in the book are sound and valid. However, the book was written based on Python 2.5 instead of Python 3.0 which is a sticking point; I say this because the original release date in late 2008 would have allowed for for at least Python 2.6, but I digress. Each project in the book builds upon the previous module that was covered which is good, however the opportunity to teach core programming principals at one time in the beginning is missed. The text is easy to read and the syntax is explained well with relevant explanations. By the end of the book, the reader should be able to make a text-based programs, a windowed program, and different forms of arcade games. I was very pleased to see the layout for a card game which no one else has done to date. However, the author presents a lot of various graphic user interface mechanisms and doesn't really focus enough on them before moving on. Several editors for python are covered as well; some are challenging to install and configure which could be discouraging. I would like to point out that the author's use of EasyGUI is great because it is easier to use than Tkinter that comes standard with Python and allows the user to make text based programs more user friendly. However, he moves from EasyGUI to Pygame (which could be a book unto itself) and then to Python Card (which needs another module wxpython). My point is that it would have been better if he had stuck with EasyGUI and focused more on one of the graphic modules instead of dabbling with all of them. I was fortunate that the book was offered at my local library. If you dont get this book, then I would recommend "Invent Your Own Computer Games with Python, 2nd Edition" by Al Sweigart which is written in Python 3 (and available as a free PDF) or "Game Programming: The L Line, The Express Line to Learning" (The L Line: The Express Line To Learning) by Andy Harris even though it's written with Python 2.
