这个例子我是从书上复制下来的    求帮助？谢谢。

报的错误：AttributeError: 'tuple' object has no attribute 'topleft'

self.rect
这里rect初始化在self.rect = (0,0,width,height)
它只是一个包含4个元素的tuple类型，不存在 x, y, topleft,width, height 这些属性

不知道是你代码少复制了还是怎样，这样肯定是不对的。

恩我也觉得不是可书上确实是这样的
书 python游戏编程入门第108页创建MySprite

self。rect = Rect（0，0，width，height）（书上加了Rect）我先是加了Rect 错误显示没有Rect定义而后我把Rect删掉直接打self。rect= （0，0，width，height）结果就显示上面的错误

Rect是他定义的一个类。你要用它，得把Rect定义的代码也加进去
