面向对象-组合

继承实现代码重用

class People:
    school="luffcity"
    def __init__(self, name, age, sex,):
        self.name = name
        self.age = age
        self.sex = sex

class Teacher(People):
    schoole=‘Luffycity‘
    def __init__(self,name,age,sex,level,salary):
        super(Teacher,self).__init__(name,age,sex)
        self.level=level
        self.salary=salary
    def teach(self):
        print("%s is teaching" % self.name)
class Student(People):
    schoole = ‘Luffycity‘
    def __init__(self, name, age, sex, class_time):
        super(Student, self).__init__(name, age, sex)
        self.class_time=class_time
    def learn(self):
        print("%s is learning" % self.name)
t1=Teacher(‘alex‘,18,‘male‘,10,3000)
s1=Student(‘zhangsan‘,28,‘female‘,‘08:30:00‘)
