Comment (by vbraun):
In fact, the order is fixed in the example (otherwise the doctest would
occasionally fail). But it is only fixed in this case coincidentally
(CPython hash table implementation detail and consecutive hashes for Sage
integers).
Perhaps a better example
{{{
sage: d = dict([(chr(i+97), i) for i in range(26)])
sage: d # note: our displayhook sorts output by keys!
{'a': 0,
'b': 1,
'c': 2,
'd': 3,
'e': 4,
'f': 5,
'g': 6,
'h': 7,
'i': 8,
'j': 9,
'k': 10,
'l': 11,
'm': 12,
'n': 13,
'o': 14,
'p': 15,
'q': 16,
'r': 17,
's': 18,
't': 19,
'u': 20,
'v': 21,
'w': 22,
'x': 23,
'y': 24,
'z': 25}
sage: d.keys() # random order
