DNS BLACK LIST Information

I need to analysis some IPs, so I need to check DNS BLACK LISTS.

I made simple checking DNS black Lists using python.

   ip = dat  
   type =None  
   status = ""  
   #path = "/query/bl?ip="  
   #path +=ip  
   host = "http://www.spamhaus.org/query/bl?ip="+ip  
   USER_AGENT = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.107 Safari/537.36"

   results = requests.get(host,  
               params = {"ip": ip},  
               headers = {"Host": "www.spamhaus.org",  
                    "User-Agent": USER_AGENT,

                    }  
               )  
   try:   
     html = results.text  
   except UnicodeDecodeError:  
     html = u' '.join(results.text).encode('utf-8').strip()  
   soup = BeautifulSoup(html)  
   tag = soup.findAll('b')  
   for item in tag:  
     if "is listed in the" in item.text:  
       #print item.text  
       status = "Block"  
       return status  
     else :  
       status = "Allow"  
   return status  
 iplists = open('iplists.txt','r')  
 save = open('result.csv', 'w')  
 for ip in iplists:  
   ip = str(ip).replace("\n","")  
   print " "*8 + "[-] " + ip  
   try:   
     result = blacklist(ip)  
   except UnicodeDecodeError:  
     result = u' '.join(blacklist(ip)).encode('utf-8').strip()  
   save.write(ip + ",\"" + result + "\"\n")  
   if result:  
     print " "*12 + result  
 iplists.close()  
 save.close()  

Input IPs to iplists.txt, then it makes result.csv.
