The None Object
Note that the PyTypeObject
for None
is not directly exposed in the Python/C API. Since None
is a singleton, testing for object identity (using ==
in C) is sufficient. There is no PyNone_Check()
function for the same reason.
- PyObject*
Py_None
The Python None
object, denoting lack of value. This object has no methods. It needs to be treated just like any other object with respect to reference counts.
-
Py_RETURN_NONE
Properly handle returning Py_None
from within a C function (that is, increment the reference count of None and return it.)
