Hello Tobi,

According to:

    http://www.python.org/doc/ref/bitwise.html

I think you're looking for the exclusive or (XOR) bitwise operator '^'.
For example:

######
>>> bits = [0, 1]
>>> for x in bits:
...     for y in bits:
...         print x, y, x ^ y
...
0 0 0
0 1 1
1 0 1
1 1 0
######

Is this where you're getting stuck, or is it somewhere else?

Good luck to you.
