Python 3.0.1 (r301:69556, Feb 14 2009, 22:08:17) >>> [x*x for x in range(3)] [0, 1, 4] >>> [(x*x for x in range(3))] [<generator object <genexpr> at 0x6779b8>] I think you mean this (from http://docs.python.org/3.0/whatsnew/3.0.html): Also note that list comprehensions have different semantics: they are closer to syntactic sugar for a generator expression inside a list() constructor, and in particular the loop control variables are no longer leaked into the surrounding scope.
