关于python：’pygame.Surface’对象没有属性’color’


'pygame.Surface' object has no attribute 'color'

所以，我的问题是，我试图画一个矩形，但我不断地得到一个错误，说'pygame.Surface' object has no attribute 'color'。有人能帮我吗？

跟随python zen explicit比implicit好。

Often, the first argument of a method is called self. This is nothing
more than a convention: the name self has absolutely no special
meaning to Python. Note, however, that by not following the convention
your code may be less readable to other Python programmers, and it is
also conceivable that a class browser program might be written that
relies upon such a convention.

这意味着您应该将第一个参数设置为self，并且您还忘记了comma，代码应该如下所示：

def draw(self,screen):
    pygame.draw.rect(screen, self.color,(self.x, self.y, self.w, self.h))

看看这个问题，为什么总是把self作为类方法的第一个参数？和Python文档以查看更多细节。
