re.search experts needed on fqdn stripping..

[rh0dium]

OK Duh..

After thinking about it for a bit longer i simplified it but still have
the same problem..

e =[]
hosts = [ "poundcake.fpdn.com", "scorpion.fpdn.com", "loghost",
"scorpian", "localhost", "lan" ]

ignore = [ "localhost", "loghost", "timehost", "mailhost" ]

for host in hosts:
    sn = re.split( "\.", host)
    if not sn[0] in ignore:
        e.append(host)
        ignore.append(sn[0])
print e

But this STILL gives me some problems..
['poundcake.nsc.com', 'scorpion.fqdn.com', 'scorpian', 'lan']

Nope - OK I am an idiot - try spelling idiot..

Thanks
