7.1.2 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.
New in version 2.4.
