Finding a python object in c++

[Brian Matt]

Initially I was confused by your response because of my lack of
knowledge of how the Python interpreter works. I did a bit more
research and things are much more clear. My biggest problem was not
understanding how all defined objects are stored in the dictionary for
the imported module. Once I figured this out I was able to use the
following code to get f1 and call func.

//Assume python initialized and module imported
dict = PyModule_GetDict(module);
PyObject* pInst = PyDict_GetItemString(dict, "f1");
if(pInst) {
	PyObject *pValue;
	pValue = PyObject_CallMethod(pInst, "func", "");
	if(pValue) {
		Py_DECREF(pValue);
	}
}

Note: this code doesn't handle error situations like making sure the
pInst variable is an instance object

Thanks,
