8 Python provides two general-purpose iterator objects. The first, a sequence
9 iterator, works with an arbitrary sequence supporting the :meth:`__getitem__`
10 method. The second works with a callable object and a sentinel value, calling
11 the callable for each item in the sequence, and ending the iteration when the
12 sentinel value is returned.
15 .. cvar:: PyTypeObject PySeqIter_Type
17 Type object for iterator objects returned by :cfunc:`PySeqIter_New` and the
18 one-argument form of the :func:`iter` built-in function for built-in sequence
24 .. cfunction:: int PySeqIter_Check(op)
26 Return true if the type of *op* is :cdata:`PySeqIter_Type`.
31 .. cfunction:: PyObject* PySeqIter_New(PyObject *seq)
33 Return an iterator that works with a general sequence object, *seq*. The
34 iteration ends when the sequence raises :exc:`IndexError` for the subscripting
40 .. cvar:: PyTypeObject PyCallIter_Type
42 Type object for iterator objects returned by :cfunc:`PyCallIter_New` and the
43 two-argument form of the :func:`iter` built-in function.
48 .. cfunction:: int PyCallIter_Check(op)
50 Return true if the type of *op* is :cdata:`PyCallIter_Type`.
55 .. cfunction:: PyObject* PyCallIter_New(PyObject *callable, PyObject *sentinel)
57 Return a new iterator. The first parameter, *callable*, can be any Python
58 callable object that can be called with no parameters; each call to it should
59 return the next item in the iteration. When *callable* returns a value equal to
60 *sentinel*, the iteration will be terminated.
