He's not using Python3, see the print statement and the file function.
But even with the appropriate changes the behaviour will be the same in
3.1 as in 2.x.
I think Steven may be remembering the conversation here on c.l.p
a month or two back where folks were asking to turn os.listdir()
into an iterator (or create an os.xlistdir() or os.iterdir()
function) because directories with lots of files were causing
inordinate slowdown. Yes, listdir() in both 2.x and 3.x both
return lists while such a proposed iterator version could be
changed on the fly by interim file/directory creation.
