Another solution (avoiding the preparer) is to simply define
sage: def xor(a,b): return eval("%s^%s"%(a,b))
....:
sage: xor(1,0)
1
sage: xor(1,1)
0
which mimics the native Python behavior:
Python 2.5.1 (r251:54863, Oct 5 2007, 13:50:07)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 1^0
1
>>> 1^1
0
