Answer 1

En attrapant tous socket.error exceptions, et le relancer si l'attribut errno n'est pas égal à 111. Ou, mieux encore, utilisez errno.ECONNREFUSED constante à la place:

import errno
from socket import error as socket_error

try:
    senderSocket.send('Hello')
except socket_error as serr:
    if serr.errno != errno.ECONNREFUSED:
        # Not the error we are looking for, re-raise
        raise serr
    # connection refused
    # handle here
