Python 的property装饰器的使用

1. 方法一：
class Person:

    def __init__(self,name):
        self.__name=name

    def get_name(self):
        return self.__name

    def set_name(self,new_name):
        self.__name=new_name

    def del_person(self,name):
        del p2.__name

    #property 函数为系统内置函数
    name=property(fget=get_name, fset=set_name, fdel=del_person)


2. 方法二：

class Person2:
    def __init__(self,name):
        ''
        self.__name=name

    @property
    def name(self):
        return self.__name

    @name.setter
    def name(self,new_name):
        self.__name=new_name
        return self.__name

    @name.deleter
    def name(self):
        print('你被除名了')
        del self.__name

if __name__ == '__main__':
    p1 = Person('张三')
    print(p1.name)
    p1.name = '李四'
    print(p1.name)

    p2=Person2('JiuJiu')
    print(p2.name)
    p2.name= 'PerQi'
    print(p2.name)
    del p2.name
