--------看了这篇文章，觉得很有意思，后面博友评论的也很多。其实我也一直在纳闷为什么e,r,s,t,i键敲击的最多。后来就用想应该写个程序验证一下，拿起了小半年没有用过的python，费了一个小时，终于搞定。

69 126 ~ 259这里统计了ucos操作系统代码和unix操作系统代码，代码量一般，但是我觉得这两个系统的代码写的比较标准比较有代表性。从运行的结果看出，e,r,s,t,i,*,空格键用的比较多，其实我也不知道那位作者是如何统计的，我也只是统计了两个操作系统的代码，可能有偏差，但是我相信偏差不会太大。
有兴趣的博友可以测试一下c#、汇编等语言的键敲击率，也欢迎提出宝贵意见。
