7.5.5 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.
