66.Python：在子类派生的新方法中重用父类功能

# Python learning
# coding:utf-8

# 方法一：“指名道姓”地调用某一个类的函数 =》不依赖继承关系
# 方法二：调用super()会得到一个特殊的对象，该对象专门用来引用父类的属性，且严格按照MRO规定的顺序向后查找

class People:
    school = 'Old Boy'

    def __init__(self, name, sex, age):
        self.name = name
        self.sex = sex
        self.age = age


class Teacher(People):
    def __init__(self, name, sex, age, title):
        super().__init__(name, age, sex)    # 调用的是绑定方法，自动传入self
        self.title = title

    def teach(self):
        print('%s is teaching' % self.name)


obj = Teacher('lili', 'female', 28, '高级讲师')
print(obj.__dict__)
print(obj.name)
