Not a bug...

Python 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> x = range(10)
>>> y = xrange(10)
>>> type(x)
<type 'list'>
>>> type(y)
<type 'xrange'>
>>> help(xrange)
Help on class xrange in module __builtin__:

class xrange(object)
 |  xrange([start,] stop[, step]) -> xrange object
 |
 |  Like range(), but instead of returning a list, returns an object that
 |  generates the numbers in the range on demand.  For looping, this is
 |  slightly faster than range() and more memory efficient.
