You can always use OrderedDict :
htttp://www.voidspace.org.uk/python/odict.html
from odict import OrderedDict
my_dict = OrderedDict(some_dict.keys())
keys = my_dict.keys()
keys.sort()
my_dict.setkeys(keys)
print my_dict
Of course if your ordering requirement was *that* trivial, you could do

I have a code snippet here that prints a dict in an arbitrary order.
(Certain keys first, with rest appearing in sorted order). I didn't
want to subclass dict, that's error-prone, and overkill for my needs. I
just need something that returns a value like dict.__str__, with a key
ordering I specify.
