我已經在python編碼之前，但我還沒有用過tkinter很多。我寫了這段代碼，我找不出爲什麼它不工作。我檢查了互聯網，但沒有發現任何東西。這已經發生過，但不幸的是我找不到該程序。Tkinter畫布部件
這是代碼
from tkinter import *
import time
import threading
import random
C = Canvas()
class ball(threading.Thread):
def run(self):
x = 1
y = 1
ball = C.create_oval(0,0,10,10,fill = "Green")
C.pack()
while True:
C.move(ball,x,y)
C.update()
time.sleep(0.03)
if C.coords(ball)[0] > 200:
x = x - random.randint(1,2)
if x > 2:
x = 2
elif x < -2:
x = -2
if C.coords(ball)[1] > 200:
y = y - random.randint(1,2)
if y > 2:
y = 2
elif y < -2:
y = -2
if C.coords(ball)[0] < 0:
x = x + random.randint(1,2)
if x > 2:
x = 2
elif x < -2:
x = -2
if C.coords(ball)[1] < 0:
y = y + random.randint(1,2)
if y > 2:
y = 2
elif y < -2:
y = -2
for i in range(3):
class Child(ball):
pass
childball = Child()
childball.start()
time.sleep(1)
它使每次返回不同的錯誤，例如

誰能幫助。
