Help Making A Toggle GUI

[TheBabaYaga202]

def toggle_gui():
    for tog in gui:
        if tog[0] == default_window:
            default_window = Label(the_window, bg = 'gray', height=3, width=25, bd=1,
            relief = 'raised', font =('times', 18, 'bold'))
            default_window.pack(fill=X, padx=5, pady=5)
        
        elif tog[1] == on_window:
            on_window = Label(the_window, text = 'ON', bg = 'green', height=3, width=25, bd=1,
            relief = 'raised', font =('times', 18, 'bold'))
            on_window.pack(fill=X, padx=5, pady=5)

        else:
            off_window = Label(text = 'OFF', bg = 'red', height=3, width=25, bd=1,
            relief = 'raised', font =('times', 18, 'bold'))
            off_window.pack(fill=X, padx=5, pady=5)

toggle_button = Button(text = 'Toggle',bg = 'gray', height=1, width=15,
relief = 'raised', font =('times', 10))

toggle_button.pack()

How can I make this code go back and forth displaying on_window and off_window?
