Not in your use case. Tuple unpacking will iterate, and so it doesn't matter whether it's an actual list or an iterator: >>> a, b, c = xrange(3) >>> a 0 >>> b 1 >>> c 2 There are certainly contexts where a sequence and its iterator are not interchangeable. You missed an obvious one: >>> range(3) == xrange(3) False -- Erik Max Francis && [EMAIL PROTECTED] && http://www.alcyone.com/max/ San Jose, CA, USA && 37 20 N 121 53 W && AIM erikmaxfrancis I will always remember / This moment -- Sade -- http://mail.python.org/mailman/listinfo/python-list
