python 中類的繼承與方法重寫（一）

#父類Person
class Person():  
    def __init__(self,name,age,hair):
        self.name = name
        self.age = age
        self.hair = hair

    def talk(self):
        print("Person is talking----")

#子類 Chinese
class Chinese(Person):  #先繼承 Person，再重構自身類
    def __init__(self,name,age,language,hair):    # name age  hair 都是繼承的父類 Person
        Person.__init__(self,name,age,hair)       #繼承父類的構造方法  
        self.language = language                  # Chinese 類中的 language, name、age、hair 已繼承父類Person

    def walk(self):
        print("Person is walking----")

c = Chinese('phone',21,'French','yello')
print (c.name)
print (c.age)
print (c.language)
print(c.hair)


運行結果：

print(c.talk())



打印結果：
child is talking-----
