前言
作为目前全世界最大的视频网站，它几乎全是用Python来写的
该网站目前是行业内的在线视频服务提供商，其系统每天处理数千万个视频片段，为全球数千名用户提供高水平的视频上传、分发、展示和浏览服务。2015年2月，央视首次将春晚推送到网站。[En]
The website is currently an online video service provider in the industry, and its system processes tens of millions of video clips every day, providing high-level video upload, distribution, display and browsing services for thousands of users around the world. In February 2015, CCTV pushed the Spring Festival Gala to the website for the first time.
