Python provides two general-purpose iterator objects. The first, a sequence
iterator, works with an arbitrary sequence supporting the __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.

.PySeqIter_New
(PyObject *seq)Return value: New reference.
Return an iterator that works with a general sequence object, seq. The
iteration ends when the sequence raises IndexError
for the subscripting
operation.
PyCallIter_Type

and the two-argument form of the iter()
built-in function.PyCallIter_Check
(op)PyCallIter_Type
.PyCallIter_New
(PyObject *callable, PyObject *sentinel)Return value: New reference.
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.
