Apart from the problems that others have mentioned, the above
statement is NOT doing what you think it is. (pair1 or pair2) will
always produce pair1, because pair1, a tuple of length 2, cannot be
false. So the statement is equivalent to:
if pair1 in incompatibles:
What you want is:
if pair1 in incompatibles or pair2 in incompatibles:
Cheers,
