You misunderstand. The problem with the function is not that it doesn't
exit, it's just that with
> root.after(200, next_image)
it schedules itself to be reinvoked by tkinter after 200 seconds. If you
want to limit that to 10 times instead of indefinitely you can introduce a
counter:
n = 10
def next_image():
global n
myLabel.config(image=random.choice(monster_images))
n -= 1
if n > 0:
root.after(200, next_image)
