Python's tail -f implementation for remote files

Basically what i want to do is to read a file
that is being constantly appended to but which
is located on a remote server.
I found this for doing BASH's tail -f in python:

import os
tailoutputfile = os.popen('tail -f syslog')
while 1:
line = tailoutputfile.readline()
if len(line)==0: # change the termination condition
break
process_line(line)

and it works great. But not sure how to use this with
ssh command to connect to remote machine.

Any tips?

ssh host_address 'tail -f file_name'

Should do it (from the command line). Off course, you can put this into
popen as well. If you log in with a public key (see ssh-keygen), you do
not have to supply a password using the console.

Best regards.
