在子類中派生出新的方法重用父類的方法，有兩種實現方式

方式一：指名道姓(不依賴繼承)

class Hero:
    def __init__(self,name,damage,zing):
        self.name = name
        self.damage = damage
        self.zing = zing

    def attack(self,enemy):
        enemy.zing -= self.damage

class Yang(Hero):
    def attack(self,enemy):
        Hero.attack(self,enemy) 
 
#指名道姓的重用方法，可以在非繼承的情況下使用
        print("from Yang Class")
    pass

class Lin(Hero):
    pass

g1 = Yang(‘楊學偉‘,100,100)
r1 = Lin(‘林書行‘,100,200)

print(r1.zing)
g1.attack(r1)
print(r1.zing)

方式二：super(依賴繼承)

class Hero:
    def __init__(self,name,damage,zing):
        self.name = name
        self.damage 
 
= damage
        self.zing = zing

    def attack(self,enemy):
        enemy.zing -= self.damage

class Yang(Hero):
    def attack(self,enemy):
        super(Yang,self).attack(enemy) #super(Yang,self)是一個對象 ，依賴於繼承
        print("from Yang Class")
    pass

class Lin(Hero):
    pass

g1 = Yang(‘楊學偉‘,100,100)
r1 
 
= Lin(‘林書行‘,100,200)

print(r1.zing)
g1.attack(r1)
print(r1.zing)

class Hero:
    def __init__(self,name,damage,zing):
        self.name = name
        self.damage = damage
        self.zing = zing
    def attack(self,enemy):
        enemy.zing -= self.damage

class Yang(Hero):
    def __init__(self,name,damage,zing,weapon):
        # self.name = name
        # self.damage = damage
        # self.zing = zing
        # Hero.__init__(self,name,damage,zing)
        super(Yang,self).__init__(name,damage,zing) #super是一個對象，所以再綁定方法的時候不用加第一個參數
        self.weapon = weapon

    def attack(self,enemy):
        Hero.attack(self,enemy) #指名道姓的重用方法，可以在非繼承的情況下使用
        print("from Yang Class")
    pass

g1 = Yang(‘楊學偉‘,100,100,‘聖劍‘)
print(g1.__dict__)

super練習

#super
class A:
    def f1(self):
        print("from A")
        super(A,self).f1() #super是基於C類的mro往後面尋找,而不A類的mro，所以可以去綁定B類的f1方法

class B:
    def f1(self):
        print("from B")

class C(A,B):
    pass

c = C()
c.f1()
# print(C.mro())

在子類中重用父類的屬性
