Python 3.x Python基于属性获取类对象名称

例如，如何获得座位3中的玩家姓名？谢谢大家!

注意，我不知道p3在其中

class Player:
  def __init__(self, name, seat, balance):
    self.name = name
    self.seat = seat
    self.balance = balance

dealer = Player('Dealer', 7, 1000)
p1 = Player('Player1', 1, 100)
p2 = Player('Player2', 2, 100)
p3 = Player('Player3', 3, 100)
p4 = Player('Player4', 4, 100)
p5 = Player('Player5', 5, 100)
p6 = Player('Player6', 6, 100)

---

最简单的方法是将你所有的玩家对象放入一个列表&在列表中循环检查它们的属性

player_list = [p1, p2, p3, p4, p5, p6]

for player in player_list:

    if player.seat == 3:
        print(player.name)

我想你不是想只打印姓名

p3.name

如果您想跟踪您的类的所有实例，请参考：和

如果我应用上面引用的两个参考文献中提到的相同逻辑，那么您的代码可能如下所示：

class Player(object):
    # create a class attribute to keep track of all the instances of the class
    instances = []
    def __init__(self, name, seat, balance):
        self.name = name
        self.seat = seat
        self.balance = balance
        Player.instances.append(self)

    # class method to access player instances by seat
    @classmethod
    def get_players_at_seat(cls, seat):
        return (p for p in cls.instances if p.seat == seat)

dealer = Player('Dealer', 7, 1000)
p1 = Player('Player1', 1, 100)
p2 = Player('Player2', 2, 100)
p3 = Player('Player3', 3, 100)
p4 = Player('Player4', 4, 100)
p5 = Player('Player5', 5, 100)
p6 = Player('Player6', 6, 100)

# Get iterator containing all players at seat 3
players_at_seat_3 = Player.get_players_at_seat(3)

# Print their names
for player in players_at_seat_3:
    print(f"{player.name} is sitting at seat 3")

---

get_players\u at_seat（）

函数是一个类方法，它返回一个迭代器，该迭代器包含

实例

中的所有玩家，这些玩家的

seat

属性设置为

seat

的给定值。然后，您可以在迭代器上进行迭代，并打印座位3上的球员姓名。

我想您不是想只打印姓名

p3.name

您可以将他们放入列表中，根据

.seat

筛选项目，并检查他们的

.name

s。使用现有的代码，不需要额外的内务管理，就没有Python技巧可以获得您想要的内容。您可以制作座椅到对象的地图。这是一种方法。您可以将它们放在一个列表中，并根据
