敲击最多的键------验证

--------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。

import os

alist = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\
         0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\
         0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\
         0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\
         0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\
         0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,\

                #print   directory+item+"/"
                lstallfl(directory+item+"/")

            elif os.path.isfile(directory+item):

        alllines = f.readlines()
        f.close()

def finalprocess():
    for i in range(56,91):
        alist[i+32] += alist[i]
        alist[i] = 0

    for i in range(32,65):
        print i,chr(i),alist[i]

上面是写的代码，我们看一下运行结果：

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。
