Suppose I have an instance of Klass called foo.  In the C code I have:
    int tmp;
    PyObject *value;
    PyObject *pmod;

    pmod = PyImport_ImportModule ("foo");
    value = PyObject_GetAttrString (pmod, "a");
    PyArg_ParseTuple(value, "i", &tmp);
    printf("Value = %d\n",tmp);

I should get "Value = 1" outputed to the screen right?  I don't; I get
some realy big number.  I'm not sure what is wrong.  I've tried several
different combinations of variables and pointers and I can't get it. 
What's wrong with the code?  Thanks.
