生成一个10行10列的随机数字矩阵，每个数字都在1到100之间。
```
import random

matrix = [[random.randint(1,100) for j in range(10)] for i in range(10)]
print(matrix)
```

输出结果：
```
[[70, 20, 34, 55, 76, 94, 46, 10, 94, 6], 
 [54, 2, 32, 44, 15, 63, 60, 58, 76, 89], 
 [77, 21, 31, 83, 63, 68, 62, 75, 46, 63], 
 [24, 20, 91, 68, 90, 29, 78, 87, 44, 39], 
 [21, 27, 78, 61, 63, 87, 57, 96, 17, 70], 
 [77, 30, 78, 24, 76, 89, 47, 74, 17, 66], 
 [76, 70, 22, 19, 96, 67, 2, 58, 58, 66], 
 [82, 24, 49, 67, 74, 61, 28, 82, 49, 21], 
 [6, 82, 94, 53, 2, 9, 53, 95, 27, 78], 
 [39, 69, 82, 27, 15, 78, 97, 4, 68, 82]]
