#!/usr/local/python3.5/bin/python3class Person(object):    def __init__(self,name):        self.name=name    def get_name(self):        print('this is get name')        return self.name    def set_name(self,name):        print('this is set name')        self.name=name    def del_name(self):        print('this is del name')        del self.name    Name = property(get_name,set_name,del_name,'name property ...')if __name__=="__main__":    jlx=Person('Jianglexing')    print(jlx.Name)
