This is not a book for developers interested in learning Python:
If you can already code then the book will probably drive you insane. It’s intended for people who have no coding chops to build up their skills before starting a more detailed book.
The book goes over all the basic data structures, boolean algebra, if-statments, while-loops etc. He even snuck a little parsing in there :)
If a friend or coulleague is interested in learning how to program, this would be a great guide.
