Arup,
Good choice! (thought I recognised the example-problem) The three books
in the "Python Craftsman" series/bundle: "Apprentice", "Journeyman", and
"Master" are a thoroughly recommendable resource. As the titles infer,
they start at a beginner level and become more complex over time. Even
seasoned pythonista can learn from them.
Did you start with "Apprentice" and work 'up'? How are you finding them?
Are they recommendable to others?
Did the Python Tutor help you 'see' what was happening and how values
were changing whilst the code executed?

I have no relationship with either resource, other than as a happy user.

Hello,
DL, the book I am reading is https://leanpub.com/python-journeyman .. It is an
awesome book. The code is in page #351.
David and Chris, The analogy you used to answer my questions were super
helpful. I could answer my own question by putting some effort by dry running
the code ofcourse. In that case, I am 100% sure the analogies were used in this
email would never come to me.
Thanks again to all of you.
Thanks,

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!
