Hi Vicki,


You can use the exclusive or (XOR) bitwise operator: '^'.  For example:


###
>>> 8 ^ 7
15
>>> (8 ^ 7) ^ 7
8
###


The 'operator' module,

    http://www.python.org/doc/lib/module-operator.html

also contains XOR, but exposes it as a function instead of a built-in
operator.  We can access it like this:

###
>>> import operator
>>> operator.xor(8, 7)
15
>>> operator.xor(operator.xor(8, 7), 7)
8
###



Hope this helps!
