通常情况下，您希望将字典层次结构镜像到对象中，而不是列表或元组，它们通常处于最低级别。我是这样做的:

class defDictToObject(object):

    def __init__(self, myDict):
        for key, value in myDict.items():
            if type(value) == dict:
                setattr(self, key, defDictToObject(value))
            else:
                setattr(self, key, value)

所以我们这样做:

myDict = { 'a': 1,
           'b': { 
              'b1': {'x': 1,
                    'y': 2} },
           'c': ['hi', 'bar'] 
         }

并获得:

x.b.b1。* 1

X.c ['hi'， 'bar']

这是另一个实现:

class DictObj(object):
    def __init__(self, d):
        self.__dict__ = d

def dict_to_obj(d):
    if isinstance(d, (list, tuple)): return map(dict_to_obj, d)
    elif not isinstance(d, dict): return d
    return DictObj(dict((k, dict_to_obj(v)) for (k,v) in d.iteritems()))

[编辑]遗漏了在列表中处理字典的部分，而不仅仅是其他字典。添加修复。

x = type('new_dict', (object,), d)

然后再加上递归，就完成了。

编辑这是我如何实现它:

>>> d
{'a': 1, 'b': {'c': 2}, 'd': ['hi', {'foo': 'bar'}]}
>>> def obj_dic(d):
    top = type('new', (object,), d)
    seqs = tuple, list, set, frozenset
    for i, j in d.items():
        if isinstance(j, dict):
            setattr(top, i, obj_dic(j))
        elif isinstance(j, seqs):
            setattr(top, i, 
                type(j)(obj_dic(sj) if isinstance(sj, dict) else sj for sj in j))
        else:
            setattr(top, i, j)
    return top

>>> x = obj_dic(d)
>>> x.a
1
>>> x.b.c
2
>>> x.d[1].foo
'bar'

这个怎么样:

from functools import partial
d2o=partial(type, "d2o", ())

然后可以这样使用:

>>> o=d2o({"a" : 5, "b" : 3})
>>> print o.a
5
>>> print o.b
3

如果你的dict来自json.loads()，你可以在一行中将它转换为对象(而不是dict):

import json
from collections import namedtuple

json.loads(data, object_hook=lambda d: namedtuple('X', d.keys())(*d.values()))

请参见如何将JSON数据转换为Python对象。

这是另一种将字典列表转换为对象的替代方法:

def dict2object(in_dict):
    class Struct(object):
        def __init__(self, in_dict):
            for key, value in in_dict.items():
                if isinstance(value, (list, tuple)):
                    setattr(
                        self, key,
                        [Struct(sub_dict) if isinstance(sub_dict, dict)
                         else sub_dict for sub_dict in value])
                else:
                    setattr(
                        self, key,
                        Struct(value) if isinstance(value, dict)
                        else value)
    return [Struct(sub_dict) for sub_dict in in_dict] \
        if isinstance(in_dict, list) else Struct(in_dict)
