导读：虽然我大部分使用php生成markdown，但python库确实也比较丰富的不要不要，php composer也是参考学习python包管理，才会让php也有一种搭积木的感觉。

使用python将markdown转换成html的情况比较多，今天我们将另一个库将html转换为markdown。

html2text

安装

1.使用pip

pip install html2text #python3使用pip3

2.源码安装

如果使用的是python3将下面的python后面加一个3

git clone --depth 1 https://github.com/Alir3z4/html2text.git

python setup.py build

python setup.py install

使用

import html2text

html = "<p><strong>hello </strong> https://xxx.com </p>"
md = html2text.html2text(html)
print(md)

运行结果

**hello** https://xxx.com

高级用法

忽略链接即a标签

import html2text
text_maker = html2text.HTML2Text()
text_maker.ignore_links = True
text_maker.bypass_tables = False
html = html
text = text_maker.handle(html)
print(text)

运行结果

**hello** https://xxx.com

链接

如果将ignore_links = False 运行结果

**hello** https://xxx.com

[链接](https://xxx.com)

我们可以看到开启之后只提取文本，而关闭后变成了markdown的链接语法
