This style of access is clear, concise, and convenient. The use of iterators
pervades and unifies Python. Behind the scenes, the :keyword:`for` statement
calls :func:`iter` on the container object. The function returns an iterator
object that defines the method :meth:`__next__` which accesses elements in the
container one at a time. When there are no more elements, :meth:`__next__`
raises a :exc:`StopIteration` exception which tells the :keyword:`for` loop to
terminate. You can call the :meth:`__next__` method using the :func:`next`
built-in function; this example shows how it all works::

Having seen the mechanics behind the iterator protocol, it is easy to add
iterator behavior to your classes. Define an :meth:`__iter__` method which
returns an object with a :meth:`__next__` method. If the class defines
:meth:`__next__`, then :meth:`__iter__` can just return ``self``::

Anything that can be done with generators can also be done with class based
iterators as described in the previous section. What makes generators so
compact is that the :meth:`__iter__` and :meth:`__next__` methods are created
automatically.

Another key feature is that the local variables and execution state are
automatically saved between calls. This made the function easier to write and
