This book was written to be read linearly, from start to nish. That being said, if you know thebasics and need help with a specic notation or operation, then you can ip straight to thatsection and get started. This book was designed for you to read on your workstation, on thescreen, not on a tablet or eReader. My hope is that you have the book open right next to youreditor and run the examples as you read about them.This book is not intended to be read passively or be placed in a folder as a reference text. Itis a playbook, a workbook, and a guidebook intended for you to learn by doing and then applyyour new understanding with working Python examples. To get the most out of the book, Iwould recommend playing with the examples in each tutorial. Extend them, break them, thenx them. Try some of the extensions presented at the end of each lesson and let me know howyou do.
