A list comprehension is a syntax form such as:

    [<expression> for <var> in <sequence>]

It was added in Python 2 (a few months ago; your books may be older
than that) and you'll fit it mentioned at
http://www.python.org/2.0/
(look for the header "List Comprehensions" about 3/4th of the way
down this big page).
