for domain in all_data:

    # 抽取出域名

    if 'http' in domain:

        domain = domain.replace('https://', '').replace('http://', '')

    if '/' in domain:

        domain = domain.split('/')[0]

    res = re.findall('\.(.+?)\.(.+)',domain)

    # 剔除前缀

    if res:

        domain = '.'.join(list(res[0]))

    print(domain)
