创建类的实例
# 创建类的对象(实例化类)
# python中实例化类不需要使用关键字new(也没有这个关键字),类的实例化类似函数调用方式。
student1 = Student('cuiyongyuan',10)
student2 = Student('yuanli', 10)
student1.display_student()
student2.display_student()
student1_class = student1.get_class()
student2_class = student2.get_class()
类的定义
# coding: utf-8
# 创建一个类,类名称第一个字母大写,可以带括号也可以不带括号
