Python - Writing to the hosts file

How can I add a new line to the hosts file (located C:/Windows/System32/drivers/etc/hosts)? This file is protected and requires administrator privileges to be modified - can Python detect if it cannot edit the file and display an error?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

As Superdave said...
>>> import sys
>>> try :
...   fh = open( '/etc/hosts', 'w+' );
...   fh.close();
... except :
...   t, v = sys.exc_info()[ :2 ]
...   print 'Exception  type: %s' % str( t );
...   print 'Exception value: %s' % str( v );
...
Exception  type: exceptions.IOError
Exception value: [Errno 13] Permission denied: '/etc/hosts'
