python慢在哪里_求大神分析一下我的python脚本慢在哪里?

请大神们分析下这个python脚本为什么会运行这么慢.

初衷: 公司有个料号系统, 在网站上输入料号就能查询相关的资料, 一般情况下, 我会ctrl+c, 打开网站, ctrl+v, 点击查询, 得到资料.

脚本实现方式: 我ctrl+c料号, 脚本调用windows的clipboard API, 拿到所复制的text, 然后用requests模拟正常浏览器的GET, 最后通过webbrowser模块打开得到的HTML.

问题: 速度很慢, 可以说比我手动在浏览器上看要慢. 基本超过6s..有什么办法可以改良呢?

谢谢!
