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.
