A reworked piece of an old project. How to update the data after cleaning, I hope you will reach it yourself.

        self.textbox = Text(self.root, height=10, width=40, wrap=WORD, state='disabled')
        self.button = Button (self.root, command=self.clear_listbox)
        self.button.pack()
        self.textbox.configure(state='disabled')
        self.textbox.pack()
        self.update("my google-fu is so bad")


    def update(self, text):
        self.textbox.configure(state='normal')
        self.textbox.insert(END, text + "\n")
        self.textbox.see(END)
        self.textbox.configure(state='disabled')

    def clear_listbox(self):
        self.textbox.configure(state='normal')
        self.textbox.delete(1.0, END)
        self.textbox.configure(state='disabled')
