As a teacher of secondary school students, and the fact that I wrote this book in the process of preparing resources to use for my own lessons, the book is largely pitched at the 12-17 age range.
I have videos on my YouTube channel that parallel many of the concepts and exercises in this book. I encourage you to check them out to help you along your programming adventures. Additionally any files you may need to complete exercises, any corrections to errors that went to print, along with guides to other useful Python tricks that may not have made it into the book, can all be found at my website.
The other thing you will want is the development tools for your web browser. I will focus on the Chrome web browser in this book, but Firefox has equally good tools you can use as well. To access the Chrome DevTools, simply right click anywhere on a website and choose Inspect.
