资深Python程序员教你统计，三国中人物名字出现的频率，很简单

merges = [ ('刘备',('玄德','玄德曰','玄德问','刘玄德','玄德大','玄德自','玄德闻','皇叔','刘皇叔')),
 ('关羽',('关公','云长','关云长')),

word_list = countWords(excludes, merges)
for i in range(30):
 word, count = word_list[i]
 print('{0:^10}{1:{3}^10}{2:^15}'.format(i+1, word, count, chr(12288))) # chr(12288)为中文空格 ```
结果如下，当然其中类似将军、英雄、主公、大哥、君这种词语无法判断指的是谁，这里仅统计能够判断的，所以这里只能做一个相对的参考。
