python 编写程序，对一个4*4的矩阵进行随机赋值，然后对该矩阵进行转置，并输出转置后的结果

可以使用以下代码实现：

import random

# 生成4*4的矩阵并随机赋值
matrix = [[random.randint(1, 10) for j in range(4)] for i in range(4)]

# 输出原始矩阵
print("原始矩阵：")
for row in matrix:
    print(row)

# 对矩阵进行转置
transpose_matrix = [[matrix[j][i] for j in range(4)] for i in range(4)]

# 输出转置后的矩阵
print("转置后的矩阵：")
for row in transpose_matrix:
    print(row)

输出结果如下：

原始矩阵：
[7, 6, 10, 2]
[3, 6, 7, 10]
[7, 6, 4, 9]
[5, 10, 2, 3]
转置后的矩阵：
[7, 3, 7, 5]
[6, 6, 6, 10]
[10, 7, 4, 2]
[2, 10, 9, 3]
