【Python】根据Dell的服务编号批量查询设备出厂日期

作者:PlutonJi / 发布于2014/10/8/ 616

此脚本利用python的HTML解析器BeautifulSoup抓取Dell网站上的设备出厂日期，通过多线程的方式可以高效的进行批量查询。


	#!/usr/bin/env python
	# -*- coding: utf-8 -*-
	
	'''
	Please install "BeautifulSoup 4" & "progressbar" via pip first:
	[user@localhost ~]$ pip install beautifulsoup4 progressbar
	Before running this script, a file 'delltags.txt' with one tag each line is required.
	Results will be exported to 'delldate.txt'.
