面向对象编程:

优点:可扩展性高

缺点:编写复杂

绑定方法:定义在类内部的方法:如果类来调用:就是一个普通函数,有几个参数就需要传几个参数对象来调用:它叫对象的绑定方法,第一个参数不需要传,自动传递

class Student:
    #变量表示属性
    school='oldboy'
    #__init__ 看好名字,不是__int__
    def __init__(x,name):
        x.name=name
    def choose(self):
        print("选课....")
    def study(self):
        print('%s学会了python'%self.name)

stu1=Student('nick')
stu1.study()
stu1=Student('李铁蛋')
stu1.study()



nick学会了python
李铁蛋学会了python

super()方法是严格按照mro()列表顺序寻找父类的
