How to properly eliminate elements in dictionary until one string remains

Question

I really need help on this

def get_winner (dict_winner):
    new_dict = {} 
    for winner in dict_winner:
        first_letter = winner[0]
        value = dict_         


        

Answer 1

My solution - in one step:

def get_winner(candidates):
    winners = dict.fromkeys(map(lambda f: f[0] for f in candidates.keys()))
    for cand, votes in candidates.iteritems(): 
        winners[cand[0]]+=votes
    return [winner for winner, vote in winners.iteritems() if vote ==max(winners.values())]

It is not fancy, but it is simple :-)
