Py_BuildValue or PyList_SetItem()

[Sheldon]

Hi,

I have a function that creates python objects out of C arrays and
returns them to Python. Below is a working example that I later want to
expand to return 12 arrays back to Python. The problem is that when I
print out the values in Python I get undesired reults. See below. Does
anyone know what is going on here?
The array values are good before the conversion.

**************************************
int createPythonObject(void) {
  int i,j,k;
  PyObject *Rva=PyList_New(12);

  for (i = 0; i < 12; i++) {
    PyObject *op = PyFloat_FromDouble((double)va[i]);
    if (PyList_SetItem(Rva,i,op) !=0) {
      fprintf(stderr,"Error in creating python va object\n");
      exit(EXIT_FAILURE);
    }
    Py_DECREF(op);
    op = 0;
  return Py_BuildValue("N",Rva);
 }

Results in Python:

<refcnt 0 at 0x80d885c>, <refcnt 0 at 0x80d885c>, <refcnt 0 at
0x80d885c>, <refcnt 0 at 0x80d885c>, <refcnt 0 at 0x80d885c>, <refcnt 0
at 0x80d885c>, <refcnt 0 at 0x80d885c>, <refcnt 0 at 0x80d885c>,
<refcnt 0 at 0x80d885c>, <refcnt 0 at 0x80d885c>, <refcnt 0 at
0x80d885c>, <refcnt 0 at 0x80d885c>


Any help is appreciated!
