创建一个包含100个随机数字的列表并计算它们的平均值。
```
import random

random_list = [random.randint(1, 100) for _ in range(100)]
average = sum(random_list) / len(random_list)

print("随机数列表: ", random_list)
print("平均数: ", average)
```

输出结果类似于：

```
随机数列表:  [94, 77, 54, 43, 87, 11, 13, 61, 90, 76, 85, 61, 36, 20, 76, 49, 30, 90, 39, 33, 20, 25, 11, 60, 76, 1, 7, 6, 97, 68, 37, 60, 55, 19, 7, 53, 16, 85, 78, 23, 88, 27, 28, 73, 76, 53, 49, 75, 31, 67, 64, 98, 48, 51, 94, 70, 45, 76, 78, 15, 37, 85, 39, 87, 97, 74, 11, 34, 20, 83, 7, 35, 19, 29, 83, 50, 9, 94, 7, 20, 11, 98, 45, 52, 54, 27, 22, 91, 37, 31, 65, 36, 16, 64, 79, 28, 59, 9, 33, 87, 37, 80, 6, 35]
平均数:  47.51
