Python显示词云图

要显示词云图，可以使用Python的第三方库wordcloud。首先需要用pip安装该库，安装命令为：

pip install wordcloud

接下来就可以使用wordcloud创建词云图了。以下是一个简单的例子：

import jieba
from wordcloud import WordCloud

text = "Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991. An interpreted language, Python has a design philosophy which emphasizes code readability (notably using whitespace indentation to delimit code blocks rather than curly brackets or keywords), and a syntax which allows programmers to express concepts in fewer lines of code than might be possible in languages such as C++ or Java. The language provides constructs intended to enable writing clear programs on both a small and large scale."

# 使用jieba分词
wordlist = jieba.cut(text, cut_all=True)
# 用空格连接分词结果，得到一个字符串
word_str = ' '.join(wordlist)
# 生成词云图
wc = WordCloud(background_color='white', max_words=2000, font_path='msyh.ttc')
wc.generate(word_str)

# 显示词云图
import matplotlib.pyplot as plt
plt.imshow(wc)
plt.axis('off')
plt.show()

以上代码将生成一个基本的英文词云图。中文词云图的生成也类似，只需替换掉分词器即可。
