想学Python的小伙伴可以关注小编的公众号【Python日志】
有很多的资源可以白嫖的哈，不定时会更新一下Python的小知识的哈！！
需要源码的小伙伴可以在公众号回复视频下载器

简介

一款简单易用的视频下载器，目前支持的平台如下：

开发环境

Python版本：3.7.8
相关模块：
requests模块；
tqdm模块；
pyfreeproxy模块；
pyecharts模块；
以及一些python自带的模块。

环境搭建

安装Python并添加到环境变量，pip安装需要的相关模块即可。

效果展示

直接输入我们的一个视频链接就可以直接下载到文件夹downloaded中

复制哔哩哔哩视频链接

b站视频链接

https://www.bilibili.com/video/BV1si4y1y76f?spm_id_from=333.999.0.0

然后就可以直接播放我们的视频啦！！
