Embedding Python

[carlos c. <hap...@ho...>]

I am thinking of using PyCXX principally for embedding Python.  Here is some 
basic code for embedding that I intend to use:

****************************************************************
#include <Python.h>

int main(int argc, char *argv[])
{
    PyObject *pName, *pModule, *pDict, *pFunc, *pValue;

    if (argc < 3)
    {
        printf("Usage: exe_name python_source function_name\n");
        return 1;
    }

    // Initialize the Python Interpreter
    Py_Initialize();

    // Build the name object
    pName = PyString_FromString(argv[1]);

    // Load the module object
    pModule = PyImport_Import(pName);

    // pDict is a borrowed reference
    pDict = PyModule_GetDict(pModule);

    // pFunc is also a borrowed reference
    pFunc = PyDict_GetItemString(pDict, argv[2]);

    if (PyCallable_Check(pFunc))
    {
        PyObject_CallObject(pFunc, NULL);
    } else
    {
        PyErr_Print();
    }

    // Clean up
    Py_DECREF(pModule);
    Py_DECREF(pName);

    // Finish the Python Interpreter
    Py_Finalize();

    return 0;
}
**********************

I assume the above will work.  Is there a more PyCXX way of doing this?

Lastly, I need to have callbacks into C++ code from Python.  The Callable 
interface is documented, but samples.  Can someone please post examples of 
how to use it?
