While it uses the "private" member-variable "_fields", you can do
>>> brucelee = namedtuple("brucelee", "x y")
>>> d = {'a': brucelee(x=123,y=321), 'b': brucelee(x=234,y=432)}
>>> dict((k, dict((s, getattr(v, s)) for s in v._fields)) for k,v in
>>> d.iteritems())
{'a': {'y': 321, 'x': 123}, 'b': {'y': 432, 'x': 234}}
which can be made a bit more readable with a helper function:
>>> def dictify(some_named_tuple):
... return dict((s, getattr(some_named_tuple, s)) for s in
some_named_tuple._fields)
...
>>> dict((k, dictify(v)) for k,v in d.iteritems())
{'a': {'y': 321, 'x': 123}, 'b': {'y': 432, 'x': 234}}
This would also make it easier to change/choose in the event
"_fields" ever changes.
