最近学习了Python的语法,写了个生成云图的小demo .

代码在Jupyter Notebook上运行 

安装执行python -m pip install –upgrade pip  python -m pip install jupyter 

首先读取文本 

filename = "E:\codeStyle.txt" with open(filename,encoding='utf-8') as f:      mytext = f.read()

通过jieba分词 

import jieba  mytext = "".join(jieba.cut(mytext))

接下来就是用wordcloud生成云图了 

from wordcloud import WordCloud

import imageio from os import path #path.join(path.dirname(__file__),"timg.jpg") trump_coloring = imageio.imread(path.join(path.abspath('.'),"E:\\timg.jpg")) wordcloud = WordCloud(font_path="E:\\simsun.ttf",                       margin=5,                       width=1800,                       height=800,                       background_color="white",                        max_words=300,                        mask=trump_coloring,                       max_font_size=40,                        random_state=42).generate(mytext) import matplotlib.pyplot as plt #%pylab inline  这行会报提示"Populating the interactive namespace from numpy and matplotlib" plt.imshow(wordcloud, interpolation='bilinear') wordcloud.to_file('E:\\output.png') plt.axis("off") plt.show()

这里面有几个坑 

1:必须是实际存在的.py文件，如果在命令行执行，则会引发异常NameError: name file is not defined；应该结合os.path.abspath()使用  2:如果报类似”ImportError: No module named scipy.misc”这样的异常,就用pip安装对应的组件  3.默认字体不支持中文,我们需要自己下载字体放到当前目录
