Python類(四)-多態

標籤：介面   通過   __name__   body   div   def   icm   studying   ati   

多態即一個介面，多種實現

按照平常直接調用

# -*- coding:utf-8 -*-__author__ = "MuT6 Sch01aR"class Person(object):    def __init__(self,name):        self.name = nameclass Student(Person):    def talk(self):        print(‘%s is studying‘%self.name)class Teacher(Person):    def talk(self):        print(‘%s is teaching‘%self.name)if __name__ == ‘__main__‘:    Student(‘John‘).talk()    Teacher(‘Jane‘).talk()

通過定義函數來實現多態

# -*- coding:utf-8 -*-__author__ = "MuT6 Sch01aR"class Person(object):    def __init__(self,name):        self.name = nameclass Student(Person):    def talk(self):        print(‘%s is studying‘%self.name)class Teacher(Person):    def talk(self):        print(‘%s is teaching‘%self.name)def Person_Talk(n):    n.talk()if __name__ == ‘__main__‘:    s = Student(‘John‘)    t = Teacher(‘Jane‘)    Person_Talk(s)    Person_Talk(t)

 通過父類調用來實現多態

# -*- coding:utf-8 -*-__author__ = "MuT6 Sch01aR"class Person(object):    def __init__(self,name):        self.name = name    @staticmethod    def Person_Talk(n):        n.talk()    class Student(Person):    def talk(self):        print(‘%s is studying‘%self.name)class Teacher(Person):    def talk(self):        print(‘%s is teaching‘%self.name)if __name__ == ‘__main__‘:    s = Student(‘John‘)    t = Teacher(‘Jane‘)    Person.Person_Talk(s)    Person.Person_Talk(t)
