- Return value: New reference. Part of the Stable ABI.
-
PyObject *PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)¶
- Return value: New reference. Part of the Stable ABI.
-
PyObject *PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)¶
- Return value: New reference. Part of the Stable ABI.
-
PyObject *PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)¶
- Return value: New reference.
-
PyObject *PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)¶
- Return value: New reference. Part of the Stable ABI.
-

如果描述符对象 descr 描述的是一个数据属性则返回非零值，或者如果它描述的是一个方法则返回
