Nice!!!!!!!!
so, using your idea:

class superDict(UserDict):
    def __init__(self, list1=[], list2=[]):
        self.data={}
        foo =map(operator.setitem, [self.data]*len(list1), list1, list2)

not tested, but that should work....

I was interested to see what the result is, if list2 is shorter than list1

>>> labels = ('name', 'age', 'salary')
>>>values = ('Monty', 42)
>>> map(operator.setitem, [d]*len(labels), labels, values)

Result...

>>> d
{'age': 42, 'name': 'Monty', 'salary': None}


Ouaaaa!!!! Nice !!!!
