为获取网上免费代理IP，闲的无聊，整合了一下，免费从三个代理网站获取免费代理IP，目的是在某一代理网站被限制时，仍可从可以访问的其他网站上获取代理IP。亲测可用哦！^_^ 仅供大家参考，以下脚本可添加函数，用于代理IP自动访问其他东西。
import requests
import urllib.request
from bs4 import BeautifulSoup
import random,time,re

from urllib.request import FancyURLopener IPRegular = r"(([1-9]?\d|1\d{2}|2[0-4]\d|25[0-5]).){3}([1-9]?\d|1\d{2}|2[0-4]\d|25[0-5])"
