So in the tests there's the code x = [ i, j, k for (i, j, k) in zip(primer, primer, range(5)) ] which results in a syntax error, so I replaced it with x = [ (i, j, k) for (i, j, k) in zip(primer, primer, range(5)) ] to get it to work. If anyone else is having trouble with that syntax error that should fix that problem.
