Invent Your Own Computer Games with Python

Pretty close to the ultimate how-to-learn python book. First, it combines an easy ramp up from expecting you to know virtually nothing to having you try out and understand Python. Second, it provides the code, the tools, and the explanations required for you build a number of increasingly sophisticated games and the know-how to branch out to creating games completely on your own.

Many of the games include flowcharts so the reader will better understand the logic needed to complete the game, and I was especially happy to see a few chapters focus on topics not necessary limited to games such as Cartesian coordinates and using the built-in Debugger.

This is an excellent way to learn Python, if you are a kid or not. Little kids can learn with their adult guide, and older kids will eat this book up in an afternoon or two.

This book is a great entry point for beginning programmers that 'gamifies' coding, allowing readers to immediately apply the concepts covered, rather than teaching basics with little application.

"If games are your thing, this would be the perfect book to learn Python."
