Need simple algorithm for newbie

[Thomas Weholt]

Don't know how optimized this is, but it's start :

import string

addresses = ['groups.google.com', 'ftp.google.com', 'ftp.google.net',
'whatever.google.org']
parsed_result = {}
for address in addresses:
    parsed_result[address[string.index(address, '.')+1:]] = None
print parsed_result.keys()
