Retrieve a variable from an embedded interpreter

[Mike Johnson]

Hi all!

I have been searching through the documentation, and it doesn't
mention how to retrieve variables from the python interpreter. :-(

I'm trying to keep my embedding work as simple as possible. I'd like
to set a bunch of variables, run a script, and collect some values
after it has finished.

The following is sorta what I had in mind. This will work for my basic
needs, the only thing missing is to somehow retrieve the python
variable "a" and store it in my application's "sa".

------
void cb_script_execute ( void ) {
        char *sa;

        Py_Initialize ();

        PyRun_SimpleString ( "a = \"hi\"" );
        PyRun_SimpleString ( "print \"a=\" + a" );
     /* PyArg_ParseTuple? */
     /* printf ( "sa = %s\n", sa ); */

        Py_Finalize ();

}
-----

Any help would be very appreciated! I've been searching through the
header files for the last couple of days, but I haven't found a
function dealing with this yet.

Thank you,
