Wow, I just *knew* there had to be some built-in function that would make this problem trivial! :) Only if order does not need to be maintained. list(set(s)) will not necessarily keep the unique characters in the order they are seen. We'll have to check with the OP to see if this is important (I just assumed that it was because of the use of list comps). Good point. For me it doesn't matter because it wasn't my problem originally. I just had a question about the list comp. But if order matters, then I guess set doesn't work? -- http://mail.python.org/mailman/listinfo/python-list
