You can just compare directly with Py_None using ==:

if (obj == Py_None)

From the docs:

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.
