>>> d = {'02': 1, '03': 1, '12': 1, '15': 2, '14': 2, '04': 3, '05': 1,
'19': 1, '32': 1, '28': 1, '27': 1, '17': 2, '25': 1}
>>> import operator
>>> sorted(d.items(), key=operator.itemgetter(1), reverse = True)
[('04', 3), ('17', 2), ('15', 2), ('14', 2), ('25', 1), ('27', 1), ('02',
1), ('03', 1), ('12', 1), ('05', 1), ('19', 1), ('32', 1), ('28', 1)]
