class gui (threading.thread):      def __init__(self):         threading.thread.__init__(self)      def run(self):         global window         window = tk()         window.title('ampel gui')         window = canvas(window, width=400, height=200)         window.pack()          button1 = button(window, text="press", command=lambda: pushbutton(25))         button1.pack()         button1.place(x=190, y=70)          button2 = button(window, text="press", command=lambda: pushbutton(12))         button2.pack()         button2.place(x=115, y=160)          (...)          window.mainloop()      @staticmethod     def output(lampe, status):         if status == 0:             if lampe == 21:                 window.create_oval(140, 30, 160, 10, fill="#ffa6a6")              if lampe == 20:                 window.create_oval(170, 30, 190, 10, fill="#fafaaa")      (...)  output(20,0)

and get:

line 120, in output window.create_oval(170, 30, 190, 10, fill="#fafaaa") nameerror: global name 'window' not defined

what should create oval intended?
