        self.screen.blit(self.image, self.rect)

类的属性问题，完全按照书上的写的，为什么还是报错

• 我也不可以import😋😋😋
  才发现您settings.py“笔误”了😄😄😄😄
  

  

  
  

  

  
  

  

  
  修改settings.py笔误后，就可以正确打印Settings.screen_width了，1200🤗🤗

setyings.py正确的样子

class Settings():
    """存储《外星人入侵》的所有设置的类"""

    def __init__(self):
        """初始化游戏的设置"""
        # 屏幕设置
        self.screen_width = 1200
        self.screen_height = 800
        self.bg_color = (230, 230, 230)
