By catching allsocket.errorexceptions, and re-raising it if the errnoattribute is not equal to 111. Or, better yet, use the errno.ECONNREFUSEDconstant instead:
通过捕获所有socket.error异常，并在errno属性不等于 111 时重新引发它。或者，更好的是，使用errno.ECONNREFUSED常量代替：
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
