本文主要是介绍Python写的一个GUI界面的小说爬虫软件,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
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
很多人学习蟒蛇,不知道从何学起。 很多人学习寻找python,掌握了基本语法之后,不知道在哪里案例上手。 很多已经可能知道案例的人,却不怎么去学习更多高深的知识。 这三类人,我给大家提供一个好的学习平台,免费获取视频教程,电子书,以及课程的源代码! QQ群:101677771 欢迎加入,一起讨论学习
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
