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

Another option:

>>> mylist = [['xxx', 879], ['yyy', 315], ['xxx', 879], ['zzz', 171], ['yyy', 315]]
>>> y = []
>>> for x in mylist:
...     if not x in y:
...             y+=[x]
...
>>> y
[['xxx', 879], ['yyy', 315], ['zzz', 171]]
