alter / modify a list as well as iterate on its items / objects

[Larry Bates]

Most of the time this is done without
a loop at all as follows:

word = ["albert", "likes", "surfing!"]

word = [x+"foo" for x in word]

word = [""albertfoo", "likesfoo", "surfing!foo"]

Much of what you use loops for in other
languages you don't need in Python.  List
comprehensions is a very powerful tool and it is
worth spending some time learning about.
