Somebody really needs to fix this "subjective questions evaluator" I usually compile my functions in a DLL and call them from excel. That works fine (well, let's just say it works) Unfortunatelly, python cannot be compiled. I know of py2exe but I don't know that it can make a DLL. So, ..., is there any other way ?
