关于python的@property

Python code

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

    @property
    def x():
        def fget(self):
            print 'I am bing got'
            return self._x
        def fset(self,key):
            print 'I am being set'
            self._x = key
        return locals()
    
a = A('zhang3')

《python核心编程》第396页，有这个实例

当我访问 a.x　　时，解释器还是把a.x当成是一个函数，而不是a这个实例的属性，不知道错误处在哪里，请高手指教啊！

没这样用过，所以不是太明白，可能代码就是错的吧。

Python 2.6里的推荐做法：
Python code

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

    @property
    def x(self):
        return self._x

    @x.getter
    def x(self):
        print 'I am bing got'
        return self._x

    @x.setter
    def x(self, key):
        print 'I am being set'
        self._x = key

还有一种写法，和你的有点像：
Python code

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

    @apply
    def x():
        def fget(self):
            print 'I am bing got'
            return self._x
        def fset(self,key):
            print 'I am being set'
            self._x = key
        return property(**locals())
