一. 内容简介
python下载bilibili视频合集
二. 软件环境
2.1vsCode
2.2Anaconda
version: conda 22.9.0
2.3代码
链接：https://pan.baidu.com/s/1WuXTso_iltLlnrLffi1kYQ?pwd=1234
三.主要流程
3.1 下载单个视频
感觉现在下载的清晰度不够，可以在找找，给这块替换了就行

那切里做展示，有些合集下载时候有点bug，还没找到问题，可以下载，但是保存路径有点问题，应该是和命令行冲突了，我就不改了
3.6 合集视频更新
原来会出现部分合集显示下载成功，但是文件夹里面没有东西，是因为有些合集名字在命令里面没办法执行，因为一些特殊符号什么的，所以把合集名字手动指定一下下载就可以了，然后多线程加上去，代码如下
