Are you talking about an array or a list ? For a list, you can say something
like:

/* untested !! */

static PyObject* f(PyObject* self, PyObject* args)
{
  PyObject* list;
  int i;

  if (!PyArg_ParseTuple(args, "O!", &PyList_Type, &list))
    return NULL;

  i = 0;
  while (i < PyList_Size(list))
  {
    PyObject* element = PyList_GetItem(list, i);
    /* do something with element */
    i++;
  }

  Py_INCREF(Py_None);
  return Py_None;
}
