这篇文章将为大家详细讲解有关python b站视频下载的示例,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
对于单P视频:直接传入B站av号或者视频链接地址(eg: 49842011或者https://www.bilibili.com/video/av49842011)
对于多P视频:
下载全集:直接传入B站av号或者视频链接地址(eg: 49842011或者Https://www.bilibili.com/video/av49842011)
2.下载其中一集:传入那一集的视频链接地址(eg: https://www.bilibili.com/video/av19516333/?p=2)
