python @property

以代码示例的方法介绍@property属性

使用@property属性

class Boy(object):
    def __init__(self, name):
        self._name = name
    
    @property
    def name(self):
        return self._name
    
    @name.setter
    def name(self, new_name):
        self._name = new_name
    
    @name.deleter
    def name(self):
        del self._name

if __name__ == "__main__":
    boy = Boy('Tom')
    print(boy.name)
    boy.name = 'Alice'
    print(boy.name)
    del boy.name
    print(boy.name)

不使用@property属性

class Boy(object):
    def __init__(self, name):
        self.name = name

    def get_name(self):
        return self.name

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

    def del_name(self):
        del self.name

if __name__ == "__main__":
    boy = Boy('Tom')
    print(boy.get_name())
    boy.set_name('Alice')
    print(boy.get_name())
    boy.del_name()
    print(boy.get_name())
