StopIteration
Having seen the mechanics behind the iterator protocol, it is easy to add
-iterator behavior to your classes. Define a :meth:`__iter__` method which
+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``::
self.index = self.index - 1
return self.data[self.index]
