使用列表实例化 class

Question

我有一个名为 Player 的 class...

class Player:
    def __init__(self,name,score=6):
        self.name=name
        self.score=score
        self.roll = 0

...我有一个名为 Game 的 class

class Game:
    def __init__(self,players):
        self.current_round = 1
        self.players=players
        self.winner_round= None
        self.player_names=[]

目前我可以实例化Game class ：

    player_1=Player('Kid1')
    player_2=Player('Kid2')
    player_3=Player('Mom')
    player_4=Player('Dad')

    game = Game([player_1,player_2,player_3,player_4])

但是，理想情况下，我更喜欢使用以下内容实例化Game class：

player_list=['Kid1','Kid2','Mom','Dad']
game = Game(player_list)

我怎样才能做到这一点？

Answer 1

显而易见的解决方案（在评论中指出）是创建Player对象列表，以便将其传递给Game ：

player_list = ['Kid1', 'Kid2', 'Mom', 'Dad']
game = Game([Player(s) for s in player_list])

另一种选择是将其封装为class方法

class Game:
    def __init__(self, players):
        self.current_round = 1
        self.players = players
        self.winner_round = None

    @classmethod
    def from_names(cls, player_names):
        return cls([Player(s) for s in player_names])


player_list = ['Kid1', 'Kid2', 'Mom', 'Dad']
game = Game.from_names(player_list)

Answer 2

为此，您可以在 Game 的构造函数中实例化玩家。

就像是：

class Game:
    def __init__(self,players):
        self.current_round = 1
        self.players=[Player(name) for name in players]
        self.winner_round= None
        self.player_names=[]

Answer 3

game = Game([Player ('jack')]) 应该可以工作。 将更多玩家添加到列表中
