A technique for solving this sort of comprehension-problem is to simulate the operations of the computer/CPU on-paper. Instruction-by-instruction, write down the names of the objects instantiated and their (current) values. As you loop through the code, those (current) values change, and you will see exactly how they change - divining (and defining) the 'why', as you go...
Of course, only old-***s (like me) have the skills to handle pen/pencil and paper technology! So, may I recommend an excellent tool which will (hopefully) achieve the same ends for you: http://pythontutor.com/
PS don't be shy about mentioning your "book", its "author", and its title (hey, go 'full-APA' adding ISBN, pageNR...). Such will be a credit to the author(s) and a possible recommendation/inspiration to fellow Pythonista!
