Um. ...I must have missed something, but I'll post nevertheless: wouldn't just [x for x in data if data.count(x) == 1] suffice? it is also "stable" preserving order of items. Lemme demo: >>> [x for x in Set(data) if data.count(x) == 1] [0.90000000000000002, 0.40000000000000002] >>> [x for x in data if data.count(x) == 1] [0.40000000000000002, 0.90000000000000002] Though I'll admit I also thought of Sets first, because I didn't remember there was such a nice method list.count(). -- # Edvard Majakari Software Engineer # PGP PUBLIC KEY available Soli Deo Gloria!
