pygame“玩个球”教程（来自第一版）第一次测试报错

如下是报错（需要放源代码吗？）：

1. Traceback (most recent call last):
   
2.   File "C:\Users\q\Desktop\编程\编程\py\project_1\main.py", line 58, in <module>
   
3.     main()
   
4.   File "C:\Users\q\Desktop\编程\编程\py\project_1\main.py", line 38, in main
   
5.     ball = Ball(ball_image, position, speed)
   
6.   File "C:\Users\q\Desktop\编程\编程\py\project_1\main.py", line 12, in __init__
   
7.     self,image = pygame.image.load(image).convert_alpha()
   
8. TypeError: cannot unpack non-iterable pygame.Surface object

如下是源代码（因为是改写……所以有一些不同的地方）

这是源码（有小改）

11行的self.image 写成了self,image
