О чём код?
.. highlight:: c .. _noneobject: The ``None`` Object ------------------- .. index:: pair: 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 and is :term:`immortal`. .. versionchanged:: 3.12 :c:data:`Py_None` is :term:`immortal`. .. c:macro:: Py_RETURN_NONE Return :c:data:`Py_None` from a function.
