How to remove duplicate tuples from a list in python?

Question

I have a list that contains list of tuples as follows.

mylist = [[\'xxx\', 879], [\'yyy\', 315], [\'xxx\', 879], [\'zzz\', 171], [\'yyy\', 315]]

Answer 1

The reason that you're not able to do this is because you have a list of lists and not a list of tuples.

What you could do is:

mytuplelist = [tuple(item) for item in mylist]
mylist = list(set(mytuplelist))

or

mylist = list(set(map(tuple, mylist)))
