如何在另一个类中访问一个类的属性？

Question

那么我想做什么
我所做的是在你的角色和敌人之间建立一个战斗系统
那么哪里出了问题
有两类：

class Ally  

以及

class Enemy

每个类都有自己独特的属性：名称、生命值、攻击和防御

class Ally  
    def __init__(self, name, health, attack, defense):  
        self.name = 'goodguy'  
        self.health = 100  
        self.attack = 50  
        self.defense = 30  
class Enemy  
    def __init__(self, name, health, attack, defense):  
        self.name = 'badguy'  
        self.health = 120  
        self.attack = 40   
        self.defense = 20  

但是阶级盟友和阶级敌人都需要对方的健康和防御属性才能造成伤害

class Ally(object):  
    def __init__(self, name, health, attack, defense):  
        self.name = goodguy  
        self.health = 100  
        self.attack = 50  
        self.defense = 30  
    def fight(self)  
        (damage moves)  
        Enemy health = Enemy.health - ((self.attack/Enemy.defense)+2)  
    def battle_script(self)   
        while self.health > 0 and Enemy.health > 0:  
            self.fight()  
            if Enemy.health <=0:  
                break  
            Enemy.fight()  
            if self.health <=0:  
                break  
        if Enemy.health() <= 0:  
            print ('The ' + Enemy.name + ' was defeated')  
        if self.health <= 0:  
            print ("You were defeated")  
class Enemy(object):   
    def __init__(self, name, health, attack, defense):  
        self.name = badguy  
        self.health = 120  
        self.attack = 40  
        self.defense = 20  
    def fight(self)  
        (random damage moves)  
        Enemy health = Ally.health - ((self.attack/Ally.defense)+2)  
Ally.battle_scrip()  

所以问题是，我不知道如何提取它们各自的属性，也就是说，在战斗脚本中调用敌人的.health，我可能会将它们全部提取到一个类中，但我宁愿将它们分开，因为当我创建更多敌人时

首先创建类的实例bob = Ally();evil_frank = Enemy();。。。除此之外，我不知道你期望在这里发生什么基于你的代码，但我猜你想要什么样的东西如下

def fight(ally,enemy):
    while ally.is_alive() and enemy.is_alive():
        ally.hp -= enemy.dmg
        enemy.hp -= ally.dmg
    print "OK FIGHT OVER SOMEONE DIED..."

fight(bob,evil_frank)
