how to uniqify a list of dict in python

Question

I have a list:

d = [{\'x\':1, \'y\':2}, {\'x\':3, \'y\':4}, {\'x\':1, \'y\':2}]

{\'x\':1, \'y\':2} comes more than once I want

Answer 1

A simple loop:

tmp=[]

for i in d:
    if i not in tmp:
        tmp.append(i)        
tmp
[{'x': 1, 'y': 2}, {'x': 3, 'y': 4}]
