#面向对象三大特性
#1.继承
#2.封装
#3.多态
'''
1.继承的定义：是一种新建类的方式，新建的类称为子类，子类会遗传父类的属性，可以减少代码冗余。
              在python中，子类（派生类）可以继承一个或者多个父类（基类，超类）

'''
#继承的写法
#class Parent1:
#    pass

#class Parent2:
#    pass

#class Sub1(Parent1):
#    pass

#class Sub2(Parent1,Parent2):
#    pass

#print(Parent1.__bases__)  #查看子类继承了那些父类
#print(Sub1.__bases__)    #查看子类继承了那些父类
#print(Sub2.__bases__)    #查看子类继承了那些父类

#在python2中类分为2种：
#1.经典类，：指没有继承object类的类，以及该类的子类。
#2.新式类，:指继承object类的类，以及该类的子类。

#在python3中统一都为新式类：
#例
#class olstu:
#    sch='oldboy'
#    def __init__(self,name,age,sex):
#        self.name=name
#        self.age=age
#        self.sex=sex

#    def learn(self):
#        print('%s is learing' %self.name)

#class olteach:
#    sch='oldboy'
#    def __init__(self,name,age,sex):
#        self.name=name
#        self.age=age
#        self.sex=sex

 #   def tech(self):
#        print('%s is teachring' % self.name)

#使用继承（效果同上）
class olper:
    sch = 'oldboy'
    def __init__(self, name, age, sex):
        self.name = name
        self.age = age
        self.sex = sex
