FrozenJSON

example 19-5 FrozenJSON

def __init__(self, mapping):
 self.__data = dict(mapping) ➊

 def __getattr__(self, name): ➋
 if hasattr(self.__data, name):
 return getattr(self.__data, name) ➌
 else:
 return FrozenJSON.build(self.__data[name]) ➍

self.__data is a dict ,function hasattr(object, name) the first parameter is object,so hasattr(self.__data, name) always return False,so step ➌ never return . am i right?
