python之类的继承

通过继承积累来得到基类的功能

class Parent(object):
    def __init__(self,name,sex):
        self.name = name
        self.sex = sex

    def talk(self):
        return f'{self.name} are talking'

    def is_sex(self):
        if self.sex == 'boy':
            return  f'{self.name} is  a boy'
        else:
            return  f'{self.name}is a girl'

class ChildOne(Parent):
    def play_football(self):
        return  f'{self.name}are playing football'

class ChildTwo(Parent):
    def play_pingpong(self):
        return  f'{self.name} are playing pingpong'

c_one =  ChildOne(name = '小慕',sex = 'boy')
result = c_one.play_football()
print(result)

c_two =  ChildTwo(name = '小云',sex = 'girl')
result = c_two.play_pingpong()
print(result)
