Python can loop over many types of sequences.. This can be a list,
tuple or string and in your example a list.

In the example for every loop x becomes 1 of the values in the list (3
in total). So in the first loop it has value "cat", second  "window"
and third "defenestrate".

How loops work in python is part of most python beginners guides, for
example "Dive into Python" [1].
