在使用二维数组创建的矩阵中，有没有办法标记哪三列和哪行的总和最大？

def markLargestSum(matrix):
    rowSums = [sum(row) for row in matrix]
    colSums = [sum(col) for col in zip(*matrix)]
    
    maxRowSum = max(rowSums)
    maxRowIdx = rowSums.index(maxRowSum)
    maxColSum = max(colSums)
    maxColIdx = colSums.index(maxColSum)
    
    markedMatrix = [row[:] for row in matrix]  # 创建一个标记矩阵，复制原始矩阵
    
    # 标记行总和最大的行
    for i in range(len(matrix[maxRowIdx])):
        markedMatrix[maxRowIdx][i] = '*'
    
    # 标记列总和最大的列
    for i in range(len(matrix)):
        markedMatrix[i][maxColIdx] = '*'
    
    return markedMatrix

# 示例用法
matrix = [[1, 2, 3],
          [4, 5, 6],
          [7, 8, 9]]

markedMatrix = markLargestSum(matrix)
for row in markedMatrix:
    print(row)
