in python

from tkinter import *
import time

tk = Tk()

Height = 300
Width = 400
tk.title('COMP3140-01 tkinter Demo')
canvas = Canvas(tk, width=Width, height= Height)
canvas.pack()

ball=canvas.create_oval(0,100,50,50, fill='red')
delta_x = 5
delta_y=0

var = StringVar()
coord = Label(canvas, textvariable=var, fg='red')
labelfont = ('times', 20, 'bold')
coord.config(font=labelfont)
canvas.create_window(180, 180, window=coord) #Add the coordinate label to the canvas

while True:
canvas.move(ball, delta_x, delta_y) #draw and move the ball object
pos=canvas.coords(ball) #records the coordinates
# Move the ball
if pos[2] > Width:
delta_x=-5
elif pos[0]<=0 :
delta_x=5

var.set('( %d, %d )'%(pos[0],pos[1])) #update the coordinates

tk.update() #update the whole frame
time.sleep(0.03)

1. Modify MovingBall_Demo.py to create the following animation script. COMP3140-01 Animation Demo ( 0, 95 ) ( 350, 255 ) Specifications: The red ball moves elockwise while the blue ball moves counter clockwise a) b) c) The red ball moves 2 times as faster as the blue ball moves At the center of the frame, the coordinates of the balls are shown in real time.
