.. highlightlang:: c.. _noneobject:The None Object---------------.. index:: object: NoneNote that the :ctype:`PyTypeObject` for ``None`` is not directly exposed in thePython/C API. Since ``None`` is a singleton, testing for object identity (using``==`` in C) is sufficient. There is no :cfunc:`PyNone_Check` function for thesame reason... cvar:: 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... cmacro:: Py_RETURN_NONE Properly handle returning :cdata:`Py_None` from within a C function (that is, increment the reference count of None and return it.)
