remove duplicates from nested dictionaries in list

Question

quick and very basic newbie question.

If i have list of dictionaries looking like this:

L = []
L.append({\"value1\": value1, \"value2\": value2, \"value3         


        

Answer 1

Here's one way:

keyfunc = lambda d: (d['value3'], d['value4'])

from itertools import groupby
giter = groupby(sorted(L, key=keyfunc), keyfunc)

L2 = [g[1].next() for g in giter]
print L2
