Cons: Too basic
Best Uses: Novice
Describe Yourself: Developer
I highly recommend this book for your 8-12 year olds (or other grownups who have an interest in learning programming). This book makes it dead simple by going over installation, basics of Python, and moving over to interesting things like graphics and building games with animations.
The font is pretty kid friendly and the graphics used throughout the book will make sure your kids are not intimidated by the programming fears. The companion website makes it easy to grab all the examples in the book in addition to more programming puzzles. I have a 7-yr old who is grasping this book slowly. That's why I feel this book is suitable more for 8 year olds. However, it all depends on your child and your 5-year old may be able to pick it up as well.
Overall, the contents of the book are great and engrossing.
