Leave out the square brackets in: sorted([w for w in set(text2) if 'cie' in w or 'cei' in w]) If you re-write that as: sorted(w for w in set(text2) if 'cie' in w or 'cei' in w) Now you've got what's called a generator expression. This iterates over the same values as the list comprehension would, but it generates them one at a time, so it doesn't have to store them all somewhere. It essentially a really neat syntax for writing coroutines. As usual, Stack Overflow does a pretty good job explaining this: http://stackoverflow.com/questions/47789/ -- http://mail.python.org/mailman/listinfo/python-list
