I bought this book knowing absolutely nothing about programming. It begins at the very start, with the basics and explains the concept of everything you learn. I haven't finished the book yet, but so far it has been great. It does have a website paired with it, that I thought was a little tricky to navigate, but that is only necissary in downloading python. Even then, you can also go to the python website as well(Which the book clearly explains). It has lots of entertaining programs to write, and includes the code in the book. For example, you start with the simple 'Game Over' program, and go on to Hangman, The Useless Trivia Program and even the three-year-old simulator! There is code for these on the website, but I find it more enjoyable to type it into the computer from the book. Like this you can see how it works, and add or change bits if you want. At the end of each chapter is a set of challenges which you can undertake. They vary, but usually include skills from the chapter. I have noticed that it seems to have a focus on game design and programming.
