Yes, but iterators aren't *classes*, they are instances.

"A generator is very similar to a function that returns an array, in that a
generator has parameters, can be called, and generates a sequence of
values. However, instead of building an array containing all the values and
returning them all at once, a generator yields the values one at a time,
which requires less memory and allows the caller to get started processing
the first few values immediately. In short, a generator looks like a
function but behaves like an iterator."
