Python属性未设置

def Property(func):
     return property(**func())

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

     @Property
     def name():
          doc = 'A''s name'

          def fget(self):
               return self._name

          def fset(self,val):
               self._name = val

          fdel = None

          print locals()
          return locals()

a = A('John')
print a.name
print a._name
a.name = 'Bob'
print a.name
print a._name

以上产生以下输出：

{'doc': 'As name','fset': <function fset at 0x10b68e578>,'fdel': None,'fget': <function fget at 0x10b68ec08>}
John
John
Bob
John

问题：怎么了？它应该是简单的东西,但我找不到它.

注意：我需要属性来进行复杂的获取/设置,而不是简单地隐藏属性.

提前致谢.
