Python：删除图像的基本程序

Question

我只是想学习 python games ，我只是尝试使用下面的代码在屏幕上删除图像，但我无法做到。任何人都可以告诉我我在哪里犯了错误吗？提前谢谢。

import sys,os,pygame
from livewires import games,colour
os.environ['SDL_VIDEODRIVER'] = 'windib'
x=320
y=320
class apple(games.Sprite):
    def __init__sprite(screen,x,y,image,dx,dy):
        x+=dx
        y+=dy
        print(x)
        print(y)
        self.init_sprite(my_screen,x,y,"G:\\Documents and Settings\\SAI\\Desktop\\py2.2\\apple.PNG")


my_screen=games.Screen(640,640)
image=games.load_image("G:\\Documents and     Settings\\SAI\\Desktop\\py2.2\\bg.JPG",transparent = 0)
my_screen.set_background(image)
games.Text(my_screen,500,40,"Score:0",50,colour.black)
scrollimage=games.load_image("G:\\Documents and Settings\\SAI\\Desktop\\py2.2\\apple.PNG",transparent = 0)
for i in range(0,6):
    apple(my_screen,x,y,scrollimage,80,0)

my_screen.mainloop()
