Yes, but as others have pointed out, you can't get that with a standard Python dict. 99% of the time when a poster asks about how to sort a dict, their problem can be solved by simply sorting the dict keys or values.

(Also note that a 'hash' is something entirely different in Python.) You can create your own type, inheriting from 'dict', that has the behaviour you want.
