[pygame] Yes I'm finally getting "Classes" with pygame.

:D I'm making progress, taught my self some what of how to move images using keyboard keys. First I took some animated ball moving script ripped it apart tried understanding it and edited it a bit, was fun. Then I rewrote it using classes :D with my basic Python Knowledge I've been studying for forever and I pulled it off. So far so good.

from pygame.locals import *
pygame.init()
size = width , height = 320, 240
speed = [0,0]
pace = 10
black = 0, 0, 0
screen = pygame.display.set_mode(size)
pygame.display.set_caption ("Demonics Ball Game[Rofl]")
ball = pygame.image.load("ball.gif")
ballrect = ball.get_rect()
print ballrect[3]
wi = 10
hi = 10
x = 0
while True:
for event in pygame.event.get():
  pygame.key.set_repeat()
  if event.type == pygame.QUIT: sys.exit()
  elif event.type == pygame.KEYDOWN:
   pygame.event.pump()
   key = pygame.key.get_pressed()
   ballrect = speed
   if key[K_DOWN] and speed[1] < height-wi:
    speed[1] += pace
   if key[K_UP] and speed[1] > 0:
    speed[1] -= pace
   if key[K_LEFT] and speed[0] > 0:
    speed[0] -= pace
   if key[K_RIGHT] and speed[0] < width-hi:
    speed[0] += pace
#ballrect = ballrect.move(speed)
#if ballrect.left < 0 or ballrect.right > width:
# speed[0] = -speed[0]
#if ballrect.top < 0 or ballrect.bottom > height:
# speed[1] = -speed[1]
screen.fill (black)
screen.blit(ball, ballrect)
