Embedding Python in Borland C++ Application

I guess I will answer that...

...
     PyObject* mathModule = PyImport_ImportModule("math");
     PyObject* mathDict = PyModule_GetDict(mathModule);
     PyObject *s;

     String result = 0;
     s=PyRun_String(exp.c_str(),eval_input,mathDict,mathDict);
     PyObject* so =PyObject_Str(s);
     result=PyString_AsString(so);
     ShowMessage("Value of expression:"+result);
...
