pygame问题~怎样让图标在移动中还可以加入键盘控制？

我现在的程序是这样的，基本上图标是横向移动，我想让它在移动的过程中我也可以用键盘控制上下左右 谢谢~

background_image_filename = 'hellokitty2.jpg'
kitty_image_filename = 'kitty.png'

SCREEN_SIZE = (640, 480)

import pygame
from pygame.locals import *
from sys import exit

pygame.init()

screen = pygame.display.set_mode((640, 480), 0, 32)
pygame.display.set_caption("Hello, World!")

x = 0
y = SCREEN_SIZE[1]/2

background = pygame.image.load(background_image_filename).convert()
kitty = pygame.image.load(kitty_image_filename)

while True:

for event in pygame.event.get():
if event.type == QUIT:
exit()

screen.blit(background, (0,0))

x += 2
if x > SCREEN_SIZE[0]:
x = 0
if SCREEN_SIZE[0]/10 < x < SCREEN_SIZE[0]*2/10:
y -= 2
elif SCREEN_SIZE[0]*2/10 <=x < SCREEN_SIZE[0] *3/10:
y += 2
elif SCREEN_SIZE[0]*3/10 <= x < SCREEN_SIZE[0]*4/10:
y -= 2
elif SCREEN_SIZE[0]*4/10 <= x < SCREEN_SIZE[0]*5/10:
y += 2
else:
y = SCREEN_SIZE [1]/2

screen.blit(kitty, (x,y))

pygame.display.update()
pygame.time.delay(20)

简单的说
用 pressed_keys = pygame.key.get_pressed()
然后判断按键

例子我发你那帖里了
