Python dmp_ground_nth Examples

Example #1

    assert dmp_ground_nth([[1],[2],[3]], (0,0), 1, ZZ) == 3
    assert dmp_ground_nth([[1],[2],[3]], (1,0), 1, ZZ) == 2
    assert dmp_ground_nth([[1],[2],[3]], (2,0), 1, ZZ) == 1

    assert dmp_ground_nth([[1],[2],[3]], (2,1), 1, ZZ) == 0
    assert dmp_ground_nth([[1],[2],[3]], (3,0), 1, ZZ) == 0

    raises(IndexError, 'dmp_ground_nth([[3],[4],[5]], (2,-1), 1, ZZ)')
