You can execute the part that is raising this exception in the try clause 
of a try/except statement:

    import socket
    ...
    try:
        some_stuff()
        some_other()
        and_so_on()
    except socket.error, err:
        whatever()

The problem, of course, is what to put in the "whatever" -- but that's 
something that only the application's author (that's you) can possibly 
know.  What DO you want to do when the server you're trying to contact is 
refusing the connection?  If you want to wait a while and retry a few 
times, put the whole try/except in a loop, and break from the loop upon 
success (e.g. in an else clause of the try/except) while letting the loop 
repeat (possibly after some warning message to the user) if it enters the 
except clause.
