我认为问题是你不能真正控制自我.windows以及

在自我.canvas存在。在

我做了两个改动，现在剧本显然起作用了……显然！在

def render(self):

    try:
        self.canvas.delete(tkinter.ALL)

        for x in range(0, self.X):
            for y in range(0, self.Y):
                self.draw_background(x, y)
        for self.x, self.y in self.snake:
            self.draw_rect(self.x, self.y, color='#00f')
        self.x, self.y = self.food
        self.draw_rect(self.x, self.y, color='#f00')
    except:
        pass

这里呢
