python property的2种使用方法

一、property类

class Person():
    def __init__(self, name):
        self.set_name(name)

    def get_name(self):
        return self.__name

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

    name = property(get_name, set_name)

p = Person('xiaoliu')
print(p.name)
p.name = 'banana'
print(p.name)

二、property修饰器

class Person():
    def __init__(self, name):
        self.name = name

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

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

p = Person('xiaoliu')
print(p.name)
p.name = 'banana'
print(p.name)
