三国演义从文本中提取出场率最高的十位人物（python）

我自己都不信我自己，竟然真的有耐心去一个个排除那些非人名的字，可能当时是真的有点闲了（捂脸）

import jieba
txt = open("三国演义.txt","r",encoding="utf-8").read()
excludes = {"将军","却说","荆州","二人","不可","不能","如此","商议","如何",
"军士","左右","军马","引兵","次日","大喜","天下","东吴","于是","今日","不敢",
"魏兵","陛下","一人","都督","人马","不知","主公"}
words = jieba.lcut(txt)
counts = {}
for word in words:
    if len(word)==1:continue
    elif word == "诸葛亮"or word == "孔明曰":
        rword = "孔明"
    elif word == "关公"or word == "云长":
        rword = "关羽"
    elif word == "玄德"or word == "玄德曰":
        rword = "刘备"
    elif word == "孟德"or word == "丞相":
        rword = "曹操"
    else:
        rword = word
    counts[rword]=counts.get(rword,0)+1
for word in excludes:
    del counts[word]
items = list(counts.items())
items.sort(key=lambda x:x[1],reverse=True)
for i in range(10):
    word,count=items[i]
    print("{0:<10}{1:>5}".format(word,count))
