Yes, they do. The difference is that they don't have any
way of *not* having references as values, so there's less
need to use the word explicitly in that way -- most of
the time it's just understood. Nevertheless, terms such
as "object reference" and "reference to an object" do
get used in relation to Python when clarity is needed.
