My bad.

class Star(pygame.sprite.Sprite):
   
        def __init__(self,ai_game):
            super().__init__()  OR  pygame.sprite.Sprite.__init__(self)
 

You can also get a two in one with:

def __init__(self, game):
        self.groups = game.your_sprite_group#, another group, another group........
        pg.sprite.Sprite.__init__(self, self.groups)

game is wherever you create the sprite from.
