如何将另一个类的两个实例传递给一个类方法？

  • 772

大佬，有代码：

class Person:
    def __init__(self, hp, name_player):
        self.hp = hp
        self.name = name_player


knight = Person(2500, 'Рыцарь')
hunter = Person(2000, 'Охотник')


class TheBattle:
    def damage_by_turns(self, player1, player2):
        print('У ', player1.name, ' ', player1.hp, ' жизней.')  
        print('У ', player2.name, ' ', player2.hp, ' жизней.')

TheBattle.damage_by_turns(hunter, knight)

给出错误消息：

Traceback (most recent call last):
    TheBattle.damage_by_turns(hunter, knight)
TypeError: damage_by_turns() missing 1 required positional argument: 'player2'

那些。我没有将骑士对象传递给该方法。请告诉我，如何解决？

    像这样正确地做：

    mochilovo = TheBattle() # создаем объект класса TheBattle
mochilovo.damage_by_turns(hunter, knight) # вызываем метод класса у объекта

    或者使用静态方法：

    class TheBattle:
    @staticmethod
    def damage_by_turns(player1, player2): # <- без self!
        print('У ', player1.name, ' ', player1.hp, ' жизней.')  
        print('У ', player2.name, ' ', player2.hp, ' жизней.')

TheBattle.damage_by_turns(hunter, knight)
