python彼岸桌面壁纸爬取
# python桌面壁纸爬取- 鉴于本人对桌面壁纸的需求（看时间长了容易视觉疲劳），又不想在网上自己一个一个找，于是找了一个图片质量比较高的网站，全部下载下来，***方便***
## **本程序只供学习使用，不得用于任何商业用途**
> 运行环境 ：
> **python 3.8.7**
> **win11**
> ***（只爬取了每种类型图片的第一页，20张）***

如何运行您的代码？
楼主的代码用python运行就好啦？PyCharm 或者VS Code 自己下载需要修改什么吗， name 'BeautifulSoup' is not defined啥都看不懂。 感谢无私分享。先测试一下 学习了，谢谢分享
