This book uses the Python programming language to teach introductory computer science topics and a handful of useful applications. You’ll certainly learn a fair amount of Python as you work through this book but along the way you’ll also learn about issues that every programmer needs to know: ways to approach a problem and break it down into parts how and why to document your code how to test your code to help ensure your program does what you want it to and more.
