headers = {'user-agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0'}

#定义获取IP函数
def get_ip():

    write_ip = open('get_ip.txt', 'w')
    for page in range(, ):
        url = 'http://www.xicidaili.com/nn/%s' % page
        r = requests.get(url, headers=headers,timeout=)

        # 用beautifulsoup库解析网页
        soup = BeautifulSoup(r.content, 'lxml')
        trs = soup.find('table', id='ip_list').find_all('tr')

        for tr in trs[:]:
            tds = tr.find_all('td')
            ip = tds[].text.strip()
            port = tds[].text.strip()
            write_ip.write('%s\n'%(ip+':'+port))
    write_ip.close()
    print('done')
