Alternatively, turn your integer into a string, reverse the string, and
turn it back:

rhodri at gnudebst:~$ python
Python 2.6.2 (release26-maint, Apr 19 2009, 01:58:18)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> n = 123
>>> int(str(n)[::-1])
321
