This function is very similar to :func:`range`, but returns an "xrange object"
This function is very similar to :func:`range`, but returns an :ref:`xrange
object <typesseq-xrange>`
instead of a list. This is an opaque sequence type which yields the same values
as the corresponding list, without actually storing them all simultaneously.
The advantage of :func:`xrange` over :func:`range` is minimal (since
:func:`xrange` still has to create the values when asked for them) except when a
very large range is used on a memory-starved machine or when all of the range's
elements are never used (such as when the loop is usually terminated with
:keyword:`break`).
