Python中类的私有属性

class Person:

    def __init__(self):
        self.name = 'wylj'
        self.__age = 18         # 私有属性

    def get_name(self):
        return self.name

    def __get_age(self):
        """私有方法"""
        return self.__age


person = Person()
print(person.get_name())
print(person.__get_age())       # 报错'Person' object has no attribute '__get_age'
print(person.name)
print(person.__age)             # 报错'Person' object has no attribute '__get_age'

私有属性只有类的内部才能调用，外部不可见，且调用会报错
私有属性标识：双下划线开头__xxx
