The simplest solution is to do

PyObject *RememberMe = NULL;

PyObject *
MyMod_Remember(PyObject *self, PyObject *args)
{
  Py_XDECREF(RememberMe); // forget old value
  Py_INCREF(args);
  RememberMe = args;      // hold onto the argument tuple
  Py_INCREF(Py_None);
  return Py_None;
}

Not sure what you are asking here - if this is a question at all.

No. Just increment the refcount on the object you get, and you can
hold onto it as long as you want.
