没有包的Python中的顺序整数矩阵

您要追加的c值始终在0到之间num_cols。您需要c根据您所在的行进行计算。类似：

def main(start_index, block):
    num_rows, num_cols = block, block
    matrix = []

    for r in range(num_rows):
        temp = []

        for c in range(0, num_cols):
            temp.append(start_index + c + (r * num_cols))

        matrix.append(temp)

    return matrix

main(0, 3)

>> [[0, 1, 2], [3, 4, 5], [6, 7, 8]]

您也可以将此作为生成器从start_index写入row * columns，从而懒惰地生成行。例如：

def main(start_index, block):
    num_rows, num_cols = block, block

    total = num_rows * num_cols

    for i in range(start_index, total + start_index, num_cols):
        yield list(range(i, num_cols + i))

list(main(10, 4))
>> [[10, 11, 12, 13], [14, 15, 16, 17], [18, 19, 20, 21], [22, 23, 24, 25]]
