Python defaultdict to dict

>>> #You can simply call dict:
>>> a
defaultdict(<type 'list'>, {'1': ['b', 'a'], '3': ['b'], '2': ['a']})
>>> dict(a)
{'1': ['b', 'a'], '3': ['b'], '2': ['a']}

# but remember that a defaultdict is a dict
# (with some special behavior, check source):
>>> isinstance(a, dict)
True

    dict_in_dict[nums[i+1]][nums[i]] = -1*nums[i+2]
dict(dict_in_dict)
