给定一个包含100个元素的列表，请找到其中第10大的数字。


列表:  [29, 22, 18, 85, 77, 3, 92, 65, 81, 31, 59, 73, 2, 33, 10, 37, 88, 18, 85, 35, 32, 43, 36, 100, 73, 7, 45, 37, 81, 35, 87, 33, 52, 90, 42, 58, 74, 23, 60, 42, 22, 98, 3, 71, 94, 69, 78, 94, 1, 4, 12, 77, 80, 89, 48, 31, 86, 44, 32, 24, 14, 19, 2, 53, 3, 75, 50, 79, 81, 44, 9, 4, 14, 63, 39, 54, 68, 99, 63, 68, 32, 42, 29, 72, 26, 47, 64, 94, 68, 70, 20, 68, 98, 35, 19, 5, 46, 25, 77, 90, 20, 69, 42, 17, 28]
对该列表进行排序，然后找到第10个数字即可。这里使用Python中的sorted函数实现：

```python
lst = [29, 22, 18, 85, 77, 3, 92, 65, 81, 31, 59, 73, 2, 33, 10, 37, 88, 18, 85, 35, 32, 43, 36, 100, 73, 7, 45, 37, 81, 35, 87, 33, 52, 90, 42, 58, 74, 23, 60, 42, 22, 98, 3, 71, 94, 69, 78, 94, 1, 4, 12, 77, 80, 89, 48, 31, 86, 44, 32, 24, 14, 19, 2, 53, 3, 75, 50, 79, 81, 44, 9, 4, 14, 63, 39, 54, 68, 99, 63, 68, 32, 42, 29, 72, 26, 47, 64, 94, 68, 70, 20, 68, 98, 35, 19, 5, 46, 25, 77, 90, 20, 69, 42, 17, 28]
sorted_lst = sorted(lst, reverse=True)
print(sorted_lst[9])  # 输出第10大的数字
```

输出：81
