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

If I understand correctly, you want to discard matches that come later in the original list but do not care about the order of the resulting list, so:

(Tested with 2.5.2)

tempDict = {}
for d in L[::-1]:
    tempDict[(d["value3"],d["value4"])] = d
L[:] = tempDict.itervalues()
tempDict = None
