It might.  xrange is always preferable to range if you expect that the
number of elements in the range -- that is, the size of the list it has
to calculate -- could be very large.  If it is, then the proxy object
xrange builds is probably going to have better performance (in terms of
memory).  If you expect they'll always be pretty small, then range will
be perform better (in terms of speed).
