Filtering a Python list to uniques

[kellygreer1]

What is the best way to filter a Python list to its unique members?
I tried some method using Set but got some "unhashable" error.

lstone = [ 1, 2, 3, 3, 4, 5, 5, 6 ]
# how do i reduce this to
lsttwo = [ 1, 2, 3, 4, 5, 6 ]

Is there a page on this in the Python in a Nutshell or the Python
Cookbook?
Did I miss something?
