没明白这个参数修改是怎么搞的？

class Animal(object):
    def __init__(self, name, age, localtion):
        self.__name=name
        self.__age=age
        self.__localtion=localtion
    def get_name(self):
        return self.__name
    def get_age(self):
        return self.__age
    def get_location(self):
        return self.__location
    def set_info(self):
        self.__name=name
        self.__age=age
        self.__localtion=localtion
monkey=Animal('wukong',25,'China')
print(monkey.get_name())
monkey.set_info()
monkey.__name='Monkeyking'
print(monkey.get_name())

monkey.set_info()

File "C:/Users/Administrator.USER-20190923TT/PycharmProjects/untitled/learn", line 55, in set_info

self.__name=name

NameError: name 'name' is not defined

print(monkey.get_name())

忘记定义参数了。哈哈可以了
