python使用代理IP

我使用代理IP是为了刷票，公司参加了比赛，投票规则是每IP只能投8票，并没有每天刷新还是永久限制，无奈之下使用代理IP,

def get_ip_list(url, headers):
    """
    获取代理服务器列表
    :param url:
    :param headers:
    :return:
    """
    web_data = requests.get(url, headers=headers)
    soup = BeautifulSoup(web_data.text, 'lxml')
    ips = soup.find_all('tr')
    ip_list = []
    for i in range(1, len(ips)):
        ip_info = ips[i]
        tds = ip_info.find_all('td')
        ip_list.append(tds[2].text + '://' + tds[0].text)
    return ip_list
