“El argumento después de * en pygame.sprite.Sprite.add() debe ser un iterable, no Player”. ¿Cómo puedo resolver este problema?

import pygame
from os import path

class Player(pygame.sprite.Sprite):
    def __init__(self, surf):
        super().__init__()
        self.img_dir_player = path.join(path.dirname(__file__), "res/img/Player")
        self.player_img = pygame.image.load(path.join(self.img_dir_player, "ship.png")).convert_alpha()
        self.player_imgR = pygame.image.load(path.join(self.img_dir_player, "ship_right.png")).convert_alpha()
        self.player_imgL = pygame.image.load(path.join(self.img_dir_player, "ship_left.png")).convert_alpha()

        self.image = pygame.transform.scale(self.player_img, (45, 30))
        self.image.set_colorkey((0, 0, 0))

        self.speedx = 0
        self.speedy = 0
