<s>Human: 生成一个5行7列的随机数字矩阵并将其输出。
</s><s>Assistant: 以下是Python代码实现：

```python
import random

matrix = []

for i in range(5):
    row = []
    for j in range(7):
        row.append(random.randint(0, 9))
    matrix.append(row)

for row in matrix:
    print(row)
```

输出结果类似于：

```
[5, 4, 1, 3, 0, 8, 2]
[9, 1, 2, 8, 5, 8, 6]
[9, 0, 5, 9, 4, 8, 4]
[4, 5, 1, 7, 5, 9, 3]
[0, 2, 8, 5, 1, 3, 4]
```
