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：

 1 #CalThreeKingdomsV2.py
 2 import jieba
 3 excludes = {"将军","却说","荆州","二人","不可","不能","如此"}
 4 txt = open("threekingdoms.txt", "r", encoding='utf-8').read()
 5 words = jieba.lcut(txt)
 6 counts = {}
 7 for word in words:
 8     if len(word) == 1:
 9         continue
10     elif word == "诸葛亮" or word == "孔明曰":
11         rword = "孔明"
12     elif word == "关公" or word == "云长":
13         rword = "关羽"
14     elif word == "玄德" or word == "玄德曰":
15         rword = "刘备"
16     elif word == "孟德" or word == "丞相":
17         rword = "曹操"
18     else:
19         rword = word
20     counts[rword] = counts.get(rword,0) + 1
21 for word in excludes:
22     del counts[word]
23 items = list(counts.items())
24 items.sort(key=lambda x:x[1],reverse=True)
25 for i in range(10):
26     word, count = items[i]
27     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：

 1 #GovRptWordCloudv2.py
 2 import jieba
 3 import wordcloud
 4 import imageio
 5 mask = imageio.imread("chinamap.png")
 6 excludes = { }
 7 f = open("threekingdoms.txt",encoding="utf-8")
 8 
 9 t = f.read()
10 f.close()
11 ls = jieba.lcut(t)
12 
13 txt = " ".join(ls)
14 w = wordcloud.WordCloud(width = 1000, height = 700, background_color = "white", font_path = "msyh.ttc")
15 w.generate(txt)
16 w.to_file("grwordclouds.png")

（二)程序运行效果如下：
