[Tutor] Tkinter Radiobutton

[Ismael Garrido]

Hello.

I can't figure out what's wrong in here! For some reason I can't 
understand, the radiobuttons don't work. The code itself is correct, the 
problem arises when I tell them that their master is self.configurar. I 
don't know why, but they don't like it.

Any help is welcome
Thanks
Ismael

        self.configurar = Tk()

            Label(self.configurar, text=textos[i]).grid(row =i, column = 0)
            entr= Entry(self.configurar)
            entr.grid(row = i, column = 1)
            entr.insert(0, valores[i])
            self.opciones.append(entr)
