Python: Uniqueness for list of lists

Question

I am curious what would be an efficient way of uniquefying such data objects:

testdata =[ [\'9034968\', \'ETH\'], [\'14160113\', \'ETH\'], [\'9034968\', \'ETH         


        

Answer 1

You can use a set:

unique_data = [list(x) for x in set(tuple(x) for x in testdata)]

You can also see this page which benchmarks a variety of methods that either preserve or don't preserve order.
