## 一、项目目录 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMyNDQ3MzAx_size_16_color_FFFFFF_t_70]

## 二、实现词云图2种方式`word_cloud、stylecloud` ##

word\_cloud ： [http://amueller.github.io/word\_cloud/][http_amueller.github.io_word_cloud]

stylecloud ：[https://github.com/minimaxir/stylecloud][https_github.com_minimaxir_stylecloud]

## 三、Python代码实现 ##
