Iterator Objects — Python v3.0 documentation

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.
int PySeqIter_Check(op)¶
Return true if the type of op is PySeqIter_Type.
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.

PyTypeObject PyCallIter_Type¶
Type object for iterator objects returned by PyCallIter_New and the two-argument form of the iter() built-in function.
int PyCallIter_Check(op)¶
Return true if the type of op is PyCallIter_Type.
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.
