+Iterator Objects
+----------------
+
+Python provides two general-purpose iterator objects.  The first, a sequence
+iterator, works with an arbitrary sequence supporting the :meth:`__getitem__`
+method.  The second works with a callable object and a sentinel value, calling
+the callable for each item in the sequence, and ending the iteration when the
+sentinel value is returned.
+
+
+.. cvar:: PyTypeObject PySeqIter_Type
+
+   Type object for iterator objects returned by :cfunc:`PySeqIter_New` and the
+   one-argument form of the :func:`iter` built-in function for built-in sequence
+   types.
+
+   .. versionadded:: 2.2
+
+
+.. cfunction:: int PySeqIter_Check(op)
+
+   Return true if the type of *op* is :cdata:`PySeqIter_Type`.
+
+   .. versionadded:: 2.2
+
+
+.. cfunction:: PyObject* PySeqIter_New(PyObject *seq)
+
+   Return an iterator that works with a general sequence object, *seq*.  The
+   iteration ends when the sequence raises :exc:`IndexError` for the subscripting
+   operation.
+
+   .. versionadded:: 2.2
+
+
+.. cvar:: PyTypeObject PyCallIter_Type
+
+   Type object for iterator objects returned by :cfunc:`PyCallIter_New` and the
+   two-argument form of the :func:`iter` built-in function.
+
+   .. versionadded:: 2.2
+
+
+.. cfunction:: int PyCallIter_Check(op)
+
+   Return true if the type of *op* is :cdata:`PyCallIter_Type`.
+
+   .. versionadded:: 2.2
+
+
+.. cfunction:: PyObject* PyCallIter_New(PyObject *callable, PyObject *sentinel)
+
+   Return a new iterator.  The first parameter, *callable*, can be any Python
+   callable object that can be called with no parameters; each call to it should
+   return the next item in the iteration.  When *callable* returns a value equal to
+   *sentinel*, the iteration will be terminated.
