1. position=position.move(speed)

从这一句开始，后面的代码全部加一个Tab缩进
会大大提升效率
修改后代码：

1. import pygame
   
2. import sys
   
3. from pygame.locals import *
   
4. 
   
5. pygame.init()
   
6. size=width,height=600,400
   
7. screen=pygame.display.set_mode(size)  #这里如果不分2句写会报错
   
8. bg=(255,255,255)
   
9. pygame.display.set_caption("Turtle Go")
   
10. turtle=pygame.image.load(r"C:\Programstudy\Python\mytest\Pygamestudy\images\turtle.png")
    
11. 
    
12. clock=pygame.time.Clock()
    
13. position=turtle_rect=turtle.get_rect()  #获得图像的位置矩形
    
14. # 小乌龟顺时针行走
    
15. speed=[5,0]
    
16. #先把旋转命令定义好
    
17. turtle_right=pygame.transform.rotate(turtle,90)  #靠右走时图片逆时针转了90°
    
18. turtle_top=pygame.transform.rotate(turtle,180)
    
19. turtle_left=pygame.transform.rotate(turtle,270)
    
20. #turtle_bottom=pygame.transform.rotate(turtle,0)
    
21. turtle_bottom=turtle  #这两句试验下来效果等同
    
22. #刚开始走顶部
    
23. turtle=turtle_top
    
24. 
    
25. while True:
    
26.     for event in pygame.event.get():
    
27.         if event.type==QUIT:
    
28.             pygame.quit()
    
29.             sys.exit()
    
30.     position=position.move(speed)
    
31.     if position.right>width:
    
32.         turtle=turtle_right  #旋转
    
33.         position=turtle_rect=turtle.get_rect()
    
34.         position.left=width-turtle_rect.width
    
35.         speed=[0,5]
    
36.     if position.bottom>height:
    
37.         turtle=turtle_bottom
    
38.         position=turtle_rect=turtle.get_rect()
    
39.         position.top=height-turtle_rect.height
    
40.         position.left=width-turtle_rect.width
    
41.         speed=[-5,0]
    
42.     if position.left<0:
    
43.         turtle = turtle_left
    
44.         position = turtle_rect = turtle.get_rect()
    
45.         position.top = height-turtle_rect.height
    
46.         speed = [0,-5]
    
47.     if position.top<0:
    
48.         turtle = turtle_top
    
49.         position = turtle_rect = turtle.get_rect()
    
50.         speed = [5,0]
    
51. 
    
52.     screen.fill(bg)
    
53.     screen.blit(turtle,position)
    
54.     pygame.display.flip()
    
55.     clock.tick(30)
