”I first heard about your book from a co-worker who wanted to
trick me with your example of how dictionaries are built. I was
almost 100% sure about the reason why the end product was a much
smaller/simpler dictionary but I must confess that I did not expect
the outcome :)
He showed me the book via video conferencing and I sort of skimmed
through it as he flipped the pages for me, and I was immediately curi-
ous to read more.
That same afternoon I purchased my own copy and proceeded to read
your explanation for the way dictionaries are created in Python and
later that day, as I met a different co-worker for coffee, I used the same
trick on him :)
He then sprung a different question on the same principle, and because
of the way you explained things in your book, I was able to not simply
guess the result but to correctly answer what the outcome would be.
That means that you did a great job at explaining things :)
I am not new in Python and some of the concepts in some of the chap-
ters are not new to me, but I must say that I do get something out of
every chapter so far, so kudos for writing a very nice book and for do-
ing a fantastic job at explaining concepts behind the tricks! I’m very
much looking forward to the updates and I will certainly let my friends
and co-workers know about your book.”
