Python: Removing duplicates from a list in one line

Yes, indeed, Python rules:

	# Let's create a list with duplicated elements:
	ls = [1,1,1,2,2,1,5,4,3,2,1]
	# And let's now remove them in just one line:
	l2 = list(set(ls))
	# See the result:
	print l2
	[1, 2, 3, 4, 5]

Voilà!

UPDATE:

This way the order is preserved and looks nice:

	from collections import OrderedDict
	list(OrderedDict.fromkeys(xs))
