Remove duplicates in a list while keeping its order (Python)

Question

This is actually an extension of this question. The answers of that question did not keep the "order" of the list after removing duplicates. How to remove these duplicates in a list (python)

biglist =   [       {'title':'U2 Band','link':'u2.com'},      {'title':'Live Concert by U2','link':'u2.com'},     {'title':'ABC Station','link':'abc.com'}  ] 

In this case, the 2nd element should be removed because a previous "u2.com" element already exists. However, the order should be kept.

Answer 1

use set(), then re-sort using the index of the original list.

>>> mylist = ['c','a','a','b','a','b','c'] >>> sorted(set(mylist), key=lambda x: mylist.index(x)) ['c', 'a', 'b']
