이터레이터 프로토콜¶
특히 이터레이터를 사용하기 위한 두 함수가 있습니다.
-
int PyIter_Check(PyObject *o)¶
- Part of the Stable ABI since version 3.8.
Return non-zero if the object o can be safely passed to
PyIter_NextItem()
and0
otherwise. This function always succeeds.
-
int PyAIter_Check(PyObject *o)¶
- Part of the Stable ABI since version 3.10.
Return non-zero if the object o provides the
AsyncIterator
protocol, and0
otherwise. This function always succeeds.Added in version 3.10.
-
int PyIter_NextItem(PyObject *iter, PyObject **item)¶
- Part of the Stable ABI since version 3.14.
Return
1
and set item to a strong reference of the next value of the iterator iter on success. Return0
and set item toNULL
if there are no remaining values. Return-1
, set item toNULL
and set an exception on error.Added in version 3.14.
-
PyObject *PyIter_Next(PyObject *o)¶
- Return value: New reference. Part of the Stable ABI.
This is an older version of
PyIter_NextItem()
, which is retained for backwards compatibility. PreferPyIter_NextItem()
.Return the next value from the iterator o. The object must be an iterator according to
PyIter_Check()
(it is up to the caller to check this). If there are no remaining values, returnsNULL
with no exception set. If an error occurs while retrieving the item, returnsNULL
and passes along the exception.
-
type PySendResult¶
The enum value used to represent different results of
PyIter_Send()
.Added in version 3.10.
-
PySendResult PyIter_Send(PyObject *iter, PyObject *arg, PyObject **presult)¶
- Part of the Stable ABI since version 3.10.
Sends the arg value into the iterator iter. Returns:
PYGEN_RETURN
if iterator returns. Return value is returned via presult.PYGEN_NEXT
if iterator yields. Yielded value is returned via presult.PYGEN_ERROR
if iterator has raised and exception. presult is set toNULL
.
Added in version 3.10.
