想學(xué)Python的小伙伴可以關(guān)注小編的公眾號(hào)【Python日志】
有很多的資源可以白嫖的哈，不定時(shí)會(huì)更新一下Python的小知識(shí)的哈！！
需要源碼的小伙伴可以在公眾號(hào)回復(fù)視頻下載器

簡(jiǎn)介

一款簡(jiǎn)單易用的視頻下載器，目前支持的平臺(tái)如下：

開發(fā)環(huán)境

Python版本：3.7.8
相關(guān)模塊：
requests模塊；
tqdm模塊；
pyfreeproxy模塊；
pyecharts模塊；
以及一些python自帶的模塊。

環(huán)境搭建

安裝Python并添加到環(huán)境變量，pip安裝需要的相關(guān)模塊即可。

效果展示

直接輸入我們的一個(gè)視頻鏈接就可以直接下載到文件夾downloaded中

復(fù)制嗶哩嗶哩視頻鏈接

b站視頻鏈接

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

然后就可以直接播放我們的視頻啦！！

代碼量太多，小編就不全部展示啦
代碼獲取可以關(guān)注小編公眾號(hào)：Python日志
在公眾號(hào)中回復(fù)：視頻下載器就可以領(lǐng)取啦
