use classes in tkinter canvas

[fardin]

I am trying to use classes to create ovals(circles) in canvas. I am a beginner and came with the following code. But the ball does not show and it does not move. I placed prints in between codes to see which codes get executed. Can someone tell me how I could fix this. Thanks

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

from tkinter import  * import random import time tk =Tk() tk.title("classy collision detection") width = 700 height = 500 x1, y1 = 10, 10 x2, y2 = 60, 60 canvas = Canvas(tk, width=width,  height=height, bg='pink') canvas.pack() xspeed = 10 yspeed = 10     class Ball:     def __init__(self, ball, colors):         self.ball = ball          self.colors = random.choice(["red", "blue", "green", \                                       "yellow", "brown", "cyan"])         self.colors.pack()         ball = canvas.create_oval(x1, y1, x2, y2, fill = colors)         ball.pack()         print("y")     def move_ball(self):             print("s")             canvas.move(ball, xspeed, yspeed)             print("h") move = Ball.move_ball move print("k") tk.update() time.sleep(0.05) canvas.mainloop()

Forgive me for cleaning up a bit:

from tkinter import  * import random import time      class Ball:     def __init__(self, parent):         self.parent = parent         self.parent.title("classy collision detection")           self.canvas = Canvas(parent, width=700,  height=500, bg='pink')         self.canvas.pack()         self.xspeed, self.yspeed = 10, 10         self.ball = self.add_ball()         for x in range(20):             self.move_ball()             self.parent.update()             time.sleep(0.05)       def add_ball(self):         x1, y1 = 10, 10         x2, y2 = 60, 60         colors = random.choice(["red", "blue", "green",                                 "yellow", "brown", "cyan"])         ball = self.canvas.create_oval(x1, y1, x2, y2, fill = colors)         return ball       def move_ball(self):         self.canvas.move(self.ball, self.xspeed, self.yspeed)   def main():     root = Tk()     ball = Ball(root)     root.mainloop()   if __name__ == '__main__':     main()
