HW 3.8 (Sudoku) still marked as 'Incorrect' in Progress

0

@PeterUdacity or @fnenu I'd appreciate it if you would respond. When I hit submit now it says this solution is correct. I have also run it against the test cases posted on this forum and it passes all except for one that inputs an invalid Sudoku square ([1,2,3],[2,3,1],[3,1,2,1]). If there is a valid test case that my code does not pass or you haven't gotten around to doing all of the re-grading please let me know. Otherwise, I think my progress for this homework problem should be updated to 'Correct'. Thanks. Here is my code:

def check_sudoku(p):
    if p == None:       # invalid array check
        return False
    largest = len(p)
    columns = []
    rownum = 0
    if largest == 0 or len(p[0]) != largest:    # invalid array checks
        return False
    while rownum < largest:
        testrow = []
        colnum = 0
        while colnum < largest:
            val = p[rownum][colnum]
            if val < 1 or val > largest:
                return False
            if val in testrow:
                return False
            testrow.append(val)
            if rownum == 0:
                testcol = []
                columns.append(testcol)
            if val in columns[colnum]:
                return False
            columns[colnum].append(val)
            colnum += 1
        rownum += 1
    return True
