he "where" creates a new DataFrame selection that contains
the same data as df, but with all values replaced by NaN (Not
a Number) except for the values that are equal to 'zz'.
"stack" returns a Series with a multi-level index created
by pivoting the columns. Here it gives a Series with the
row-col-addresses of a all the non-NaN values. The general
meaning of "stack" might be the most complex operation of
this script. It's explained in the pandas manual (see there).
"reset_index" then just transforms this Series back into a
DataFrame, and ".iloc[ :, 0 ]" and ".iloc[ :, 1 ]" are the
first and second column, respectively, of that DataFrame. These
then are zipped to get the desired form as a list of pairs.
And this is a technique very similar to reverse engineering. Thanks for
the explanation and examples. All this is really clear and I was able to
follow it easily because I have already written a version of this code
in C without any kind of external library that uses the .CSV version of
the table as data ( 234 code lines :^/ ).

Hi everyone.
