Actually, there was a small bug fix that I found, and I had a teacher who told me once that there was only 5 pseudoprimes. I realized that large numbers of prime numbers were returning false, and discovered the root of the problem, which was that my M-R test ended too late... But, it works now, thankfully.
I may switch soon to an upgraded version of the code, to be more efficient. But for now, I'm just glad to have it work! -- http://mail.python.org/mailman/listinfo/python-list
