Skip ahead to about page 13 to get more traditional questions,  There,
many of the simplest questions have invalid answers, or confusing
explanations.

For example, on page 15, the question that says " ... if a list of words
is empty..."   uses     a=""   as its source data to test with.

The first question on page 16 forgets to construct a loop, thus
processing only the first line in the file.

page 18 introduces new syntax to the language:
     print n+=1  ##will work

and reassures us in the comment that it will work !!

page 18 also claims that values are passed to function by value.
