词频统计及词云绘制

首先，在电脑上安装jieba库，进入命令提示符，输入pip install jieba，接下来就等系统自动安装

然后再进入IDLE建立一个脚本，用open函数打开只读模式，用jieba.lcut函数剪下词组，对每一个剪下的词组进行统计，最后输出。

import jieba
txt = open(r"F:清道夫.txt", "r", encoding='utf-8').read()
words  = jieba.lcut(txt)
counts = {}
for word in words:
    if len(word) == 1:  #排除单个字符的分词结果
        continue
    else:
        counts[word] = counts.get(word,0) + 1
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))

运行结果如下

 然后来绘制词云，需要先安装wordcloud库，还是用上面的方法，pip install wordcloud,安装好之后，执行如下代码

from wordcloud import WordCloud
with open("F:清道夫.txt",encoding="utf-8")as file:
    text=file.read()
    wordcloud=WordCloud(
        font_path="C:/Windows/Fonts/simfang.ttf",
        background_color="white",
        width=600,
        height=300,max_words=50).generate(text)
    image=wordcloud.to_image()
    image.show()

效果如下
