This may be an indication that you have got the wrong datatype. It may be
that you would be happier with a set.
>>> s1={'Stockholm', 'Berlin'}
>>> s2={'Berlin', 'Stockholm'}
>>> s1 == s2
True
If you need a tuple later -- for instance you want to use the tuple as a
key in a dictionary later, because you cannot use the set directly
>>> tuple(s1)
('Stockholm', 'Berlin')
>>> tuple(s2)
('Stockholm', 'Berlin')
>>>
