You've described the code in words. Next time show the code you
tried. Here's one possible solution.
First sort each sublist.
>>> L1 = [[1,2],[2,1],[3,1],[1,4],[3,3],[1,4]]
>>> for i in L1:
... i.sort()
...
>>> L1
[[1, 2], [1, 2], [1, 3], [1, 4], [3, 3], [1, 4]]
Then add L1's unique items to a new list L2.
>>> L2 = []
>>> for i in L1:
... if i not in L2:
... L2.append(i)
...
>>> L2
[[1, 2], [1, 3], [1, 4], [3, 3]]
This is not identical to your said output, but it sounds like
[1,3] == [3,1] for your purposes.
