You could instead use a dict subclass that lets you access values as 
attributes:
>>> class Dict(dict):
... def __getattr__(self, name):
... return self[name]
... def __setattr__(self, name, value):
... self[name] = value
... 
>>> d = Dict({"AppleSeed": None, "Has": None, "Horrible" : None, "Art": 42})
>>> d.Art
42
>>> d.AppleSeed
>>> d.AppleSeed = "spam"
>>> d
{'Has': None, 'Art': 42, 'AppleSeed': 'spam', 'Horrible': None}
