By catching all socket.error exceptions, and re-raising it if the errno attribute is not equal to 111. Or, better yet, use the errno.ECONNREFUSED constant instead:

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
