jieba库使用和好玩的词云

一、分析《三国演义》，得到词频统计，并对词频进行排序。

（一）具体代码如下：

#CalThreeKingdomsV2.py
import jieba
excludes = {"将军","却说","荆州","二人","不可","不能","如此"}
txt = open("threekingdoms.txt", "r", encoding='utf-8').read()
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))

（二）程序运行效果如下：

二、对以上关键词制作一个词云图

（一）具体代码如下：

#GovRptWordCloudv2.py
import jieba
import wordcloud
import imageio
mask = imageio.imread("chinamap.png")
excludes = { }
f = open("threekingdoms.txt",encoding="utf-8")

t = f.read()
f.close()
ls = jieba.lcut(t)

txt = " ".join(ls)
w = wordcloud.WordCloud(width = 1000, height = 700, background_color = "white", font_path = "msyh.ttc")
w.generate(txt)
w.to_file("grwordclouds.png")

（二)程序运行效果如下：
