I don't understand your code.
Here an example using OrderedDict from twisted:
>>> import twisted.python.util as util
>>> foo(util.OrderedDict(a = 1, b = 2, c = 3))
{'a': 1, 'c': 3, 'b': 2}
Simply I can't use a dict.
I have to do, as an example example:
foo('a', 1, 'b', 2, 'c', 3)
or
foo(['a', 'b', 'c'], [1, 2, 3])
Thanks and regards Manlio Perillo
