For example i have following
list = [[\'1\', \'2\'], [\'1\', \'3\'], [\'1\', \'4\'], [\'1\', \'5\'], [\'2\', \'1\'], [\'4\', \'1\'], [\'2\', \'6\']] >
list = [[\'1\', \'2\'], [\'1\', \'3\'], [\'1\', \'4\'], [\'1\', \'5\'], [\'2\', \'1\'], [\'4\', \'1\'], [\'2\', \'6\']]
You can try this also:-
l = [['1', '2'], ['1', '3'], ['1', '4'], ['1', '5'], ['2', '1'], ['4', '1'], ['2', '6']] res = [] for sub_list in l: if sub_list[::-1] not in res: res.append(sub_list) print(res)
Output:-
[['1', '2'], ['1', '3'], ['1', '4'], ['1', '5'], ['2', '6']]
