Given a list of dictionaries, how can I eliminate duplicates of one key, and sort by another

Question

I\'m working with a list of dict objects that looks like this (the order of the objects differs):

[
    {\'name\': \'Foo\', \'score         


        

Answer 1

One way to do that is:

data = collections.defaultdict(list)
for i in my_list:
    data[i['name']].append(i['score'])
output = [{'name': i, 'score': max(j)} for i,j in data.items()]

so output will be:

[{'score': 2, 'name': 'Baz'},
 {'score': 3, 'name': 'Foo'},
 {'score': 3, 'name': 'Bar'}]
