you-get是github上python的一个开源库(https://github.com/soimort/you-get)，使用you-get你只需要取得视频所在网页链接地址就可以很轻松的下载下来，目前you-get所支持的网站包含国内外几十个网站(youtube、twitter、腾讯、爱奇艺、优酷、bilibili等)，基本上可以满足你的需求。

1.you-get可以直接通过命令行使用(前提是你要先安装you-get：pip install you-get)

下载命令：you-get  your-url

l例如：you-get  https://www.bilibili.com/bangumi/play/ep118488?from=search&seid=5050973611974373611

效果如下：(我直接在pycharm的终端命令行执行)

2.通过python 简单调用you-get库
