2.1.5.3 XRange Type 
</H3>

<P>
The xrange type is an immutable sequence which is
commonly used for looping.  The advantage of the xrange type is that an
xrange object will always take the same amount of memory, no matter the
size of the range it represents.  There are no consistent performance
advantages.

<P>
XRange objects behave like tuples, and offer a single method:

<P>
<dl><dt><b><a name='l2h-70'><tt class='method'>tolist</tt></a></b> ()
<dd>
  Return a list object which represents the same values as the xrange
  object.
</dl>

<P>
