How to uniqufy the tuple element?

Question

i have a result tuple of dictionaries.

result = ({\'name\': \'xxx\', \'score\': 120L }, {\'name\': \'xxx\', \'score\': 100L}, {\'name\': \'yyy\', \'score\':          


        

Answer 1

I would reconsider the data structure to fit your needs better (for example dict hashed with name with list of scores as value), but I would do like this:

import operator as op
import itertools as it

result = ({'name': 'xxx', 'score': 120L },
          {'name': 'xxx', 'score': 100L},
          {'name': 'xxx', 'score': 10L},
          {'name':'yyy', 'score':20})
# groupby

highscores = tuple(max(namegroup, key=op.itemgetter('score'))
                   for name,namegroup in it.groupby(result,
                                                    key=op.itemgetter('name'))
                   )
print highscores
