7.5.6 Iterator Objects


7.5.6 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
Type object for iterator objects returned by PySeqIter_New() and the one-argument form of the iter() built-in function for built-in sequence types. New in version 2.2.

int PySeqIter_Check(op)
Return true if the type of op is PySeqIter_Type. New in version 2.2.

PyObject* 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. New in version 2.2.

PyTypeObject PyCallIter_Type
Type object for iterator objects returned by PyCallIter_New() and the two-argument form of the iter() built-in function. New in version 2.2.

int PyCallIter_Check(op)
Return true if the type of op is PyCallIter_Type. New in version 2.2.

PyObject* 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. New in version 2.2.
