Iterator Objects¶
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.

PyTypeObject PySeqIter_Type¶
-  Part of the Stable ABI.Type object for iterator objects returned by PySeqIter_New()and the one-argument form of theiter()built-in function for built-in sequence types.
- 
int PySeqIter_Check(PyObject *op)¶
- Return true if the type of op is - PySeqIter_Type. This function always succeeds.
- 
PyObject *PySeqIter_New(PyObject *seq)¶
- Return value: New reference. Part of the Stable ABI.Return an iterator that works with a general sequence object, seq. The iteration ends when the sequence raises IndexErrorfor the subscripting operation.
- 
PyTypeObject PyCallIter_Type¶
-  Part of the Stable ABI.Type object for iterator objects returned by PyCallIter_New()and the two-argument form of theiter()built-in function.
- 
int PyCallIter_Check(PyObject *op)¶
- Return true if the type of op is - PyCallIter_Type. This function always succeeds.
- 
PyObject *PyCallIter_New(PyObject *callable, PyObject *sentinel)¶
- Return value: New reference. Part of the Stable ABI.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.
