Any help please?
it looks like you are confusing methods (bound to class objects) and functions (bound to modules). if your doMath is a function defined in a module, use PyObject* PyObject_Call(PyObject *callable_object, PyObject *args, PyObject *kw) i.e. PyObject resultObj = PyObject_Call(doMath,NULL,NULL); If, however, doMath is declared as a class-bound method, you have to use PyObject_CallMethod() with a pointer to an instance of this class as the first argument.
