Probably something like:

    import sys
    try:
      from cStringIO import StringIO
    except:
      from StringIO import StringIO
    sys.stdout = StringIO()
    sys.stderr = StringIO()

Each file output is seperate here, but could be the same to redirect
the output to both places.  This will allow you to retrieve it in your
embedded C program thusly:

    PyObject *sys_stdout, *str;
    sys_stdout = PySys_GetObject("stdout");
    str = PyObject_CallMethod(sys_stdout, "getvalue", NULL);
    fprintf(stderr, "Python output: %s\n", PyString_AsString(str));
    Py_DECREF(str);
    Py_DECREF(sys_stdout);
