有没有一种方法可以写到n代数矩阵的整行/整列？

# 创建一个3x3的矩阵并初始化为0
matrix = [[0 for _ in range(3)] for _ in range(3)]

# 写入整行
row_index = 1  # 要写入的行索引
value = 5  # 要写入的值

for i in range(len(matrix[row_index])):
    matrix[row_index][i] = value

# 写入整列
col_index = 2  # 要写入的列索引
value = 8  # 要写入的值

for i in range(len(matrix)):
    matrix[i][col_index] = value

# 打印矩阵
for row in matrix:
    print(row)

[0, 0, 0]
[5, 5, 5]
[0, 0, 8]
