Python类(四)-多态

多态即一个接口，多种实现

按照平常直接调用

# -*- coding:utf-8 -*-

__author__ = "MuT6 Sch01aR"

class Person(object):

    def __init__(self,name):

        self.name = name

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__':

    Student('John').talk()

    Teacher('Jane').talk()

通过定义函数来实现多态

# -*- coding:utf-8 -*-

__author__ = "MuT6 Sch01aR"

class Person(object):

    def __init__(self,name):

        self.name = name

class 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)

通过父类调用来实现多态

# -*- 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)
