No matter what i write, these guys just never get it.
No book is gonna teach you how to be an expert at anything. Just get your principles down and your syntax in your head and relax. When you need complicate or advanced python, i am sure there are 100 tutorials to teach you just that. You will just forget what decorators are and how to get them right if you just read them from a book and mov on to the next book. Rather, when you get your basics down, get a project idea and google. When you don't know how to achieve this and that, google then learn what is needed. No need for concurrency and multicore programming when you can't write a decent function.
