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 - Noneobject, denoting lack of value. This object has no methods and is immortal.
Changed in version 3.12: Py_None is immortal.
