import re
import sys
def get(domain):
        url = 'http://i.links.cn/subdomain/'
#        payload = ("domain=ycxy.com&b2=1&b3=1&b4=1")
        payload = ("domain={domain}&b2=1&b3=1&b4=1".format(domain=domain))
        r = requests.post(url=url,params=payload)
        con = r.text
        a =re.compile('value="(.+?)"><input')   #正则匹配引号里的任何字符，非贪婪
        result = a.findall(con)
        for i in result:
            print i
if __name__ == '__main__':
    command =sys.argv[1:]                       #取所有后面的参数
    f ="".join(command)                          #用空格连接
    get(f)
