Um. I'm not in a position to test your code right now, but I can't
think of any reason why it would do that..

You could do [s.strip() for s in cleanedlist] -- the .strip() string
method will strip whitespace from both ends of the string.

cleanedlist = list(set(mylist))
If you don't have python 2.4+, you will need to import the sets module.
Also, depending on what you are doing with cleanedlist, you could just
leave it as a set. Or even construct mylist as a set.
