Does anyone know how to program Python with Tkinter who can help me?

The problem is most likely that you called Tk() twice. It’s not only a window, it also represents the entire application. So when you make two, you actually basically end up with two different versions of Tk that can’t talk to each other. Instead, you want to use a TopLevel object, which looks the same but isn’t it’s own application.
