先放两张效果图：
还有这个：
是不是立马逼格满满~
这里用到的是一个有趣的模块，叫wordcloud：
github: https://github.com/amueller/word_cloud
官网: https://amueller.github.io/word_cloud/
*建议自行通过下载setup.py的方式安装，pip install 不一定能下载成功。
打开，并下载： https://github.com/amueller/word_cloud/archive/master.zip
然后 python setup.py install
安装其它依赖的模块：
下载whl文件，然后 pip install XXXX.whl
如果出现错误，请参考https://www.cnblogs.com/nice-forever/p/5371906.html
分享一下源码：

# 生成词云, 可以用generate输入全部文本(中文不好分词),也可以我们计算好词频后使用generate_from_frequencies函数
wc.generate(text)
# wc.generate_from_frequencies(txt_freq)
# txt_freq例子为[('词a', 100),('词b', 90),('词c', 80)]
# 从背景图片生成颜色值
image_colors = ImageColorGenerator(back_coloring) plt.figure()
# 以下代码显示图片
plt.imshow(wc)
plt.axis("off")
plt.show()
# 绘制词云 # 保存图片
wc.to_file(path.join(d, "名1称.png"))

"""
Image-colored wordcloud
======================= You can color a word-cloud by using an image-based coloring strategy
implemented in ImageColorGenerator. It uses the average color of the region
occupied by the word in a source image. You can combine this with masking -
pure-white will be interpreted as 'don't occupy' by the WordCloud object when
passed as mask.
If you want white as a legal color, you can just pass a different image to
"mask", but make sure the image shapes line up.
