上一版本链接:传送门

这是我用pyinstaller打包成的exe文件,便利体验:传送门(上传了正在审核,请稍等)

这里使用了第三方库pyquery,安装方法见:上一版本链接

在上一版本的基础上做个改良.先上图:

上面是代码:

这一版本重要更新如下:

1.函数封装

2,增加用户交互界面.

3,用户可自在输入小说名称查询下载

4.可选肇端下载章节

5.暂时取消单章保存模式

下一版本目标:

1.支撑模糊查询

2,增加热门小说列表

3.优化表现界面

文章结束给大家分享下程序员的一些笑话语录： N多年前，JohnHein博士的一项研究表明：Mac用户平均IQ要比PC用户低15%。超过6000多的参加者接受了测试，结果清晰的显示IQ比较低的人会倾向于使用Mac。Mac用户只答对了基础问题的75%，而PC用户却高达83%。
