use classes in tkinter canvas

[Larz60+]

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()
