Remove duplicate dict in list in Python

Question

I have a list of dicts, and I\'d like to remove the dicts with identical key and value pairs.

For this list: [{\'a\': 123}, {\'b\': 123}, {\'a\': 123}]<

Answer 1

Sometimes old-style loops are still useful. This code is little longer than jcollado's, but very easy to read:

a = [{'a': 123}, {'b': 123}, {'a': 123}]
b = []
for i in range(0, len(a)):
    if a[i] not in a[i+1:]:
        b.append(a[i])
