unexpected output while parsing file

[anna]

Thanks, its working perfectly... I have modified code for MAC OUI and working.

import re

def macvendor(mac_add):
           vendor = p.get_manuf(mac_add)
           return vendor

if __name__ == "__main__":
     dnlist = []
     maclist = []
     with open('bulkdn.txt','r') as f:
          for line in f:
              if line.strip() == '-':
                  dnlist.append(['-'*10])

              if '@ttml' in line:
                  dn = re.findall(r'\d{10}',line)
                  dnlist.append(dn)

              if 'svc:1' in line:
                  mac = re.findall(r'mac:[a-fA-F0-9]{2}[:][a-fA-AF0-9]{2}[:][a-fA-F0-9]{2}[:][a-fA-F0-9]{2}[:][a-fA-F0-9]{2}[:][a-fA-F0-9]{2}',line)
                  maclist.append(mac)

          i=0
          from manuf import manuf
          p = manuf.MacParser(update=True)
          for dn,mac in zip(dnlist,maclist):
               mac = (", ".join(mac)).split('mac:')[1]
               print('{} {} {} {}'.format(i,(", ".join(dn)),mac,macvendor(mac)))
               i+=1

Output:
