按顺序更改椭圆填充

Question

我是编程新手。我为老年人建造了康复设备，并已退休，因此在家工作。这是用于轮椅使用者腿部运动垫。我在tkinter画布上做了一个布局但是不能改变顺序的填充（红色和绿色）来显示要移动的脚和何时移动。每只脚的填充颜色需要打开约2秒，一次移动一只脚。我的代码远远是：

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()       

我尽我所能，但无法使其发挥作用。请指出我正确的方向。

您好我需要让我的问题更清楚，我会更好地尝试包含我正在使用的代码。我尝试过使用After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，我使用的东西看起来很幼稚，而且很长。幼稚是好的，但长时间意味着长时间的编辑，使其适合有特殊要求的人，他们将占多数。我用过＃34; sleep＆＃34;给予停顿。         到目前为止，该代码已完成约20％; 来自tkinter进口* 进口时间 从时间导入睡眠 import tkinter 将tkinter导入为tk 从进口时间* class App（tk.Tk）：     def init （个体经营）：         tk.Tk.的初始化（个体）         self.frame_Light = tk.Canvas（）         self.light_on = True         self.canvas = tk.Canvas（bg =＆＃34;浅蓝色＆＃34;，高度= 500，宽度= 500）         self.canvas.create_oval（171,37.5,196,62.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light1＆＃34;）＃，＃fill         self.canvas.create_oval（304,37.5,329,62.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light2＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（37.5,137.5,62.5,162.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light3＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（437.5,137.5,462.5,162.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light4＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（171,237.5,196,262.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light5＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（304,237.5,329,262.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light6＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（37.5,337.5,62.5,362.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light7＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（437.5,337.5,462.5,362.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light8＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（171,437.5,196,462.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light9＆＃34;）＃，＃fill =＆＃34; yellow＆＃34;）         self.canvas.create_oval（304,437.5,329,462.5，outline =＆＃34; black＆＃34;，tags =＆＃34; light10＆＃34;）＃，＃fill =＆＃34;黄色         self.canvas.pack（side =＆＃34; top＆＃34;，fill =＆＃34; both＆＃34;，expand = True）         self.draw_light（）
