这个是挺猴的，记不得在哪里看到的，不过也不能解决嵌套问题。

在项目中使用的是这个版本，能解决嵌套的问题：

class AttrDict(dict):
"""
A class to convert a nested Dictionary into an object with key-values
that are accessible using attribute notation (AttrDict.attribute) instead of
key notation (Dict["key"]). This class recursively sets Dicts to objects,
allowing you to recurse down nested dicts (like: AttrDict.attr.attr)
"""

def __init__(self, iterable, **kwargs):
super(AttrDict, self).__init__(iterable, **kwargs)
for key, value in iterable.items():
if isinstance(value, dict):
self.__dict__[key] = AttrDict(value)
else:
self.__dict__[key] = value
