Here's how to answer this for yourself:
PyObject* list = Py_Buildvalue("[]");
int precount;
...
PyObject* num = Py_BuildValue("i", 10);
precount = num.ob_refcnt;
PyList_Append(list, num);
<here compare precount and num.ob_refcnt>
...
If you need to do the DECREF, precount should exceed num.ob_refcnt.
If they match, the "PyList_Append" call "stole" your reference.
