Please use the proper code tags around your code. Don't quote the whole thing or your code tags won't work.

Proper code tags are
[code=python]
your code here
[/code]

Please format your code so it is somewhat readable. Also, since your ovals are equal, how would you know the difference?

This how you might do it:

import Tkinter as tk
 
def generate():
    oval1()
    frame.after(2000, oval2)
 
def oval1():
    canvas.create_oval(200, 300, 210, 310, fill='red')
 
def oval2():
    canvas.create_oval(200, 300, 210, 310, fill='blue')
 
frame = tk.Frame()
frame.pack()
 
canvas = tk.Canvas(frame, bg='white', width=500, height=500)
canvas.pack()
 
button = tk.Button(frame, fg="blue", text="GENERATE", command=generate)
button.pack()
 
frame.mainloop()
import Tkinter as tk

def generate():
    oval1()
    frame.after(2000, oval2)

def oval1():
    canvas.create_oval(200, 300, 210, 310, fill='red')

def oval2():
    canvas.create_oval(200, 300, 210, 310, fill='blue')

frame = tk.Frame()
frame.pack()

canvas = tk.Canvas(frame, bg='white', width=500, height=500)
canvas.pack()
            
button = tk.Button(frame, fg="blue", text="GENERATE", command=generate)
button.pack()

frame.mainloop()
