更改序列中的椭圆填充

Question

我是编程新手。我为老年人制造康复设备，已经退休，所以在家工作。这是一个轮椅使用者的腿部锻炼垫。我已经在tkinter画布中做了一个布局，但是不能改变填充顺序(红色和绿色)来显示移动哪只脚以及何时移动。每只脚的填充颜色需要打开大约2秒，一次移动一只脚。我对far的代码是：

from tkinter import *
import tkinter 
#from time import sleep
import time

C = tkinter.Canvas(bg="blue", height=500, width=500)
oval1 = C.create_oval (171, 37.5, 196, 62.5, outline="white")#,     #fill="yellow")
oval2 = C.create_oval (304, 37.5, 329, 62.5, outline="white")#, #fill="yellow")
oval3 = C.create_oval (37.5, 137.5, 62.5, 162.5, outline="white")#, #fill="yellow")
oval4 = C.create_oval (437.5, 137.5, 462.5, 162.5, outline="white")#, #fill="yellow")
oval5 = C.create_oval (171, 237.5, 196, 262.5, outline="white")#, #fill="yellow")
oval6 = C.create_oval (304, 237.5, 329, 262.5, outline="white")#, #fill="yellow")
oval7 = C.create_oval (37.5, 337.5, 62.5, 362.5, outline="white")#, #fill="yellow")
oval8 = C.create_oval (437.5, 337.5, 462.5, 362.5, outline="white")#, #fill="yellow")
oval9 = C.create_oval (171, 437.5, 196, 462.5, outline="white")#, #fill="yellow")
oval10 = C.create_oval (304, 437.5, 329, 462.5, outline="white")#, #fill="yellow")
C.pack()       

我已经试过所有我能做的，但都不能使它工作。请告诉我正确的方向。

嗨，我需要让我的问题更清晰，我会更好地尝试包括我正在使用的代码。我试过使用After while等，但程序要么停止，要么转到最后一个屏幕。与其他人的代码相比，我使用的代码看起来很幼稚，而且非常长。幼稚是可以的，但长意味着长的编辑，使它适合有特殊要求的人，他们将是大多数。我用“睡眠”来表示停顿。到目前为止，代码大约完成了20%；从tkinter导入*导入时间从时间导入睡眠导入tkinter作为tk从时间导入导入*类App(tk.Tk)：def init(self)：definit(Self)：def self.frame_Light = tk.Canvas() self.light_on = True self.canvas =tk.Canvas(bg=“浅蓝色”，height=500，width=500) self.canvas.create_oval(171，37.5,196，62.5，Outline=“黑色”，tags="light1")#，#fill self.canvas.create_oval (304，37.5329，62.5，outline=“黑色”，tags="light2")#，#fill=“黄色”) self.canvas.create_oval (37.5,137.5，62.5,162.5，outline=“黑色”，tags="light3")#，#fill=“黄色”) self.canvas.create_oval (437.5,137.5,462.5，162.5，outline=“黑色”，tags="light4")#，#fill=“黄色”) self.canvas.create_oval (171,237.5,196,262.5，outline=“黑色”，tags="light5")#，#fill=“黄色”) self.canvas.create_oval (304,237.5,329,262.5，outline=“黑色”，tags="light6")#，#fill=“黄色”) self.canvas.create_oval (37.5,337.5，62.5,362.5，outline=“黑色”，tags="light7")#，#fill=“黄色”) self.canvas.create_oval (437.5,337.5,462.5,362.5，outline=“黑色”，tags="light8")#，#fill=“黄色”) self.canvas.create_oval ( 437.5,437.5,196,462.5，outline=“黑色”，tags="light9")#，#fill=“黄色”) self.canvas.create_oval (304，437.5,329,462.5，outline=“黑色”，tags="light10")#，#fill=“黄色顶端(side=”self.canvas.pack“，fill=”两者“，expand=True) self.draw_light()
