    ## 2.准备红楼梦文本

    文本可以用下面链接下载


    `https://github.com/flypythoncom/flypython/blob/master/wordcloud_hlm_seg.txt`

    或者可以自己写代码，对文本进行清洗，分词。
    这里需要安装jieba分词，`pip install jieba`
    ``` python
    import jieba
    import re

    special_character_removal = re.compile(r'[，。、【 】“”：；（）《》‘’{}？！⑦%>℃.^-——=&#@￥『』]', re.IGNORECASE)

    fw=open("hlm_seg.txt","w",encoding="utf-8")

    with open('hlm.txt',encoding="utf-8") as fp:
        for line in fp:
            l = special_character_removal.sub('', line.strip())
            words=jieba.cut(l)
            t=" ".join(words)
            fw.write(t)
