Python 爬取哔站视频弹幕并实现词云图可视化

嗨喽，大家好呀~这里是爱看美女的茜茜呐

环境介绍:

python 3.8 解释器
pycharm 编辑器

第三方模块:

requests >>> pip install requests
protobuf >>> pip install protobuf

如何安装python第三方模块:

win + R 输入 cmd 点击确定, 输入安装命令 pip install 模块名 (pip install requests) 回车
在pycharm中点击Terminal(终端) 输入安装命令

👇 👇 👇 更多精彩机密、教程，尽在下方，赶紧点击了解吧~

python源码、视频教程、插件安装教程、资料我都准备好了，直接在文末名片自取就可
