You might try sets. http://docs.python.org/lib/types-set.html I'm guessing that you'd need to convert the arrays to sets. Maybe convert the arrays to lists or tuples then to sets? Maybe you might be able to directly convert the numpy arrays to sets? I haven't used numpy, so you'll need to experiment.
