python - getting rid of duplicate items in a list

Getting rid of duplicate items in a list

The trick is to temporarly convert the list in into a dictionnary:
>>> mylist = [3,5,8,5,3,12]
>>> print dict().fromkeys(mylist).keys()
[8, 3, 12, 5]
>>>

Since Python 2.5, you can also use sets:
>>> mylist = [3,5,8,5,3,12]
>>> print list(set(mylist))
[8, 3, 12, 5]
>>>
