You are welcome. However, I have to concur with the others that in terms of efficiency and reliability, which leads to household peace, you are better off starting with a prepackaged solution instead. You can keep developing your Python-powered database as a pet project for the time being. Your wife will be even more impressed if at one day you can tell her that you wrote completely customizable software that works the same or even better than the one she has been getting used to :) Even if not, you will have learned much about Python and related concepts along the way. Keep in mind, then, that you probably also need a graphical user interface.
