  • Python写的一个GUI界面的小说爬虫软件

一个小说的爬虫,带GUI界面的

 


主要功能
1.多线程提取 可使用代{过}{}过滤理
2. 实时输出过程
3. 一本书的txt文件

 

使用方法

 


1. 首先配置好python3环境,
2.新建一个空目录,在此目录下要新建start.py文件,将源码复制在start.py文件内
3. 在此目录下打开 cmd.exe,执行命令 python -m venv 。
4.分别

 

pip install requests
pip install
pip install
pip install pyinstaller

 


5.在

 

pyinstaller - F -w - *.py

 


结束后在 dist 看到下 exe已执行打包好
exe 执行文件下载
