selenium学习之安全微伴自动完成

大家好，欢迎来到IT知识分享网。

一、程序介绍

个人博客

学校网课繁多，自己又没时间去守着手机枯燥的点击下一步。既然是枯燥无味又重复执行的事情，程序员面临这种问题，，，让他自动点击或者完成就显得明智得多，程序员的时间是用来学习的。

那么如何实现自动呢，python程序员都知道的一个WEB自动化工具，那就是selenium。对python没有接触或接触较少的同学，本篇最后也附带源码以便于大家使用。

提醒：本案例仅学术研究讨论，非法用途后果自负

二、程序搭建

1. 驱动下载
   查看自己浏览器的版本后前往官网下载驱动（本篇以Edge为例）
   Edge浏览器的驱动地址为https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
   在其中找到自己对应的浏览器驱动
2. 创建项目
   本案例开发工具选择pycharm，创建工程
   
3. 加入浏览器驱动
   将下载好的驱动加入项目
   
4. 新建py文件
