class Student:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    def eat(self):
        print(self.name+'在吃饭')

stu1 = Student('张三', 20)
stu2 = Student('李四', 30)
print(id(stu1))
print(id(stu2))
print('-----为stu1绑定性别属性-----')
stu1.gender = '女'
print(stu1.name, stu1.age, stu1.gender)
print(stu2.name, stu2.age)
Student.gender = '男'
print(stu1.name, stu1.age, stu1.gender)
print(stu2.name, stu2.age, stu2.gender)

stu1.eat()
stu2.eat()

print('-----为stu1绑定show方法-----')
def show():
    print('定义在类之外的，成为函数')
stu1.show = show
stu1.show()
