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

This is the simplest way I can think of:

names = set(d['name'] for d in my_dicts)
new_dicts = []
for name in names:
    d = dict(name=name)
    d['score'] = max(d['score'] for d in my_dicts if d['name']==name)
    new_dicts.append(d)

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

Personally, I prefer not to import modules when the problem is too small.
