— Hi everyone


How I can get from this list

a = [{'name': 'a', 'sum': 1}, {'name': 'a', 'sum': 2}, {'name': 'b', 'sum': 2}]
this one
b = [{'name': 'a', 'sum': 3}, {'name': 'b', 'sum': 2}]

— Now I am doing like that

import collections

x = collections.Counter()
for i in a:
x[i['name']] += i['sum']

b = []
for k, v in x.items():
b.append({'name': k, 'sum': v})
