A function or method which uses the :keyword:`yield` statement (see section
:ref:`yield`) is called a :dfn:`generator function`. Such a function, when
called, always returns an iterator object which can be used to execute the
- body of the function: calling the iterator's :meth:`__next__` method will
- cause the function to execute until it provides a value using the
- :keyword:`yield` statement. When the function executes a
+ body of the function: calling the iterator's :meth:`iterator__next__`
+ method will cause the function to execute until it provides a value
+ using the :keyword:`yield` statement. When the function executes a
:keyword:`return` statement or falls off the end, a :exc:`StopIteration`
exception is raised and the iterator will have reached the end of the set of
values to be returned.
