   Thank you. I found a reference to the difference between range() and
xrange(), and that is the same difference between readlines() and
xreadlines() I suppose.

   With the former pair, range(10000) will create a list of 10,000 integers,
then iterate through them one at a time while xrange(10000) will iterate
without first building a separate list.
