Py_INCREF / DECREF not needed in simple C functions?

Trundling along here and reading the docs I've come
to the conclusion that if I pass simple values to
my C extensions to Python I do not need to worry
about Py_INCREF and Py_DECREF.
Am I right? For example if I only pass, say, 3
double values to a C extension function, the values
of which I extract using PyArgs_ParseTuple, then
I do not need to worry about reference counts?
Concrete example:
static PyObject* Py_ReallyWildFunc (PyObject *self, PyObject *args)
{
double x,y,z ;
if (!PyArg_ParseTuple(args, "ddd",&x,&y,&z)) {
return (NULL) ;
}
...do some really wild stuff with x,y,z...
return (Py_None) ;
}
(I know that in the future I may do more complex things,
but at the moment I'm concentraing on this simple stuff)
