tkinter-移动形状

Question

如何在Python中移动眼睛（当精神向左转时，眼睛将留在右侧）。 当我定义左移动时，我尝试了c.move（eye，-10，0），我也尝试过为眼睛隐藏状态，并创建了一个状态为normal的left_eye，但它不起作用。 谢谢。

c.pack()
school= c.create_rectangle (200, 50,600, 150, fill = 'orange')
school_window1 = c.create_rectangle (250,80, 300, 100, fill= 'yellow')

def move_girl(event):
   if event.keysym == 'Up':
        c.move (body, 0, - GIRL_step)
        c.move (head, 0, - GIRL_step)
        c.move (eye, 0, - GIRL_step)
        c.move (mouth, 0, - GIRL_step)
        c.move (hand, 0, - GIRL_step)

        c.move (eye, - GIRL_step, 0)
        c.move (mouth, _GIRL_step, 0)
        c.move (hand, - GIRL_step, 0)
    elif event.keysym== 'Right':
        c.move (body, GIRL_step, 0)
        c.move (head, GIRL_step, 0)
        c.move (eye, GIRL_step, 0)
        c.move (mouth, GIRL_step, 0)
        c.move (hand, GIRL_step, 0)
c.bind_all ('<Key>', move_girl )

您也可以使用for（）使事情变得更容易

    for body_part in [body, head, eye, mouth, hand]:
        c.move (body_part, - GIRL_step, 0)

和消除冗余代码的功能
