定义父类Role,定义属性name, 两个子类Soldier和Magicer 定义父类武器Weapon, 定义属性name, 方法attack()攻击 三个子类Sword,Knife,Mace(狼牙棒), 其中 Sword的attack伤害值为100 Knife的attack伤害值为200 Mace的attack伤害值为300 其中战士Soldier和法师Magicer可以使用任意一种武器 从控制台输入指令 1>输入A,创建Soldier 2>输入B,创建Magicer 3>输入1,创建Sword 4>输入2,创建Knife 5>输入3,创建Mace 当战士和法师满5个时,而且每个角色配备自己选择的武器, 组队去攻击,求攻击总值

父类Role的定义如下：

class Role:
    def __init__(self, name):
        self.name = name
        self.weapon = None

    def set_weapon(self, weapon):
        self.weapon = weapon

    def attack(self):
        if self.weapon is None:
            return 
        else:
            return self.weapon.attack()

子类Soldier和Magicer的定义如下：

class Soldier(Role):
    def __init__(self, name):
        super().__init__(name)

class Magicer(Role):
    def __init__(self, name):
        super().__init__(name)

父类Weapon的定义如下：

class Weapon:
    def __init__(self, name):
        self.name = name

    def attack(self):
        pass

子类Sword、Knife和Mace的定义如下：

class Sword(Weapon):
    def __init__(self, name):
        super().__init__(name)

    def attack(self):
        return 100

class Knife(Weapon):
    def __init__(self, name):
        super().__init__(name)

    def attack(self):
        return 200

class Mace(Weapon):
    def __init__(self, name):
        super().__init__(name)

    def attack(self):
        return 300

下面是主程序的实现：

soldiers = []
magicers = []
weapons = []

while True:
    command = input("请输入指令：")
    if command == "A":
        if len(soldiers) < 5:
            name = input("请输入战士的名字：")
            soldier = Soldier(name)
            soldiers.append(soldier)
            print("创建战士成功！")
        else:
            print("战士已满！")
    elif command == "B":
        if len(magicers) < 5:
            name = input("请输入法师的名字：")
            magicer = Magicer(name)
            magicers.append(magicer)
            print("创建法师成功！")
        else:
            print("法师已满！")
    elif command == "1":
        name = input("请输入武器的名字：")
        weapon =
