The `None` Object

.. index:: object: None

Note that the :c:type:`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 :c:func:`PyNone_Check` function for the same reason.

.. c:var:: 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.

.. c:macro:: Py_RETURN_NONE

   Properly handle returning :c:data:`Py_None` from within a C function (that is,
   increment the reference count of ``None`` and return it.)
