1.. highlightlang:: c 2 3.. _noneobject: 4 5The None Object 6--------------- 7 8.. index:: object: None 9 10Note that the :ctype:`PyTypeObject` for ``None`` is not directly exposed in the 11Python/C API. Since ``None`` is a singleton, testing for object identity (using 12``==`` in C) is sufficient. There is no :cfunc:`PyNone_Check` function for the 13same reason. 14 15 16.. cvar:: PyObject* Py_None 17 18 The Python ``None`` object, denoting lack of value. This object has no methods. 19 It needs to be treated just like any other object with respect to reference 20 counts. 21 22 23.. cmacro:: Py_RETURN_NONE 24 25 Properly handle returning :cdata:`Py_None` from within a C function. 26 27 .. versionadded:: 2.4 28
