【笔试题】面向对象小测试（一）

没对象？没关系，new一个，赶紧来测试下自己new的技术如何吧。

 

class Person(object):
    __country = 'China'

    def __init__(self,name,age):
        print('创建对象中。。。')
        self.__name = name
        self.age = age
        print('你的对象信息：'.center(30,'*'))
        self.__query()
        print('恭喜脱单。。。'.center(30,'*'))

    def query(self):
        print("country:%s"%self.__country)
        print("name:%s"%self.__name)
        print("age:%s"%self.age)
