A Python dictionary is an unsorted data structure, so you cannot have it sorted as you please. (I have seen that lot of people ask for a sorted dictionary and for permutation/combination functions, maybe they are batteries to be included too in the standard library.) If you need an ordered dict you can manage it yourself, keeping the lists of keys, etc, or you can use an ordered dict implementation: http://www.voidspace.org.uk/python/odict.html http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/438823 Etc.
