Python Socket timeout error

Question

I am writing a very simple udp socket connection in Python 2.7

The server side is up and running. I have trouble on the client side.

from socket import *
serverName = '127.0.0.1'
serverPort = 5444
counter = 1;
while counter < 55:
 mySocket = socket(AF_INET,SOCK_DGRAM)
 try:
 mySocket.settimeout(1.0)
 message = raw_input('')
 mySocket.sendto(message,(serverName, serverPort))
 modifiedMessage, serverAddress = mySocket.recvfrom(1024)
 except mySocket.timeout:
 print 'Request timed out!'
 mySocket.close()
 else: 
 print 'Server Response: '
 print modifiedMessage 
 mySocket.close()

I am getting the following error. except mySocket.timeout: AttributeError: '_socketobject' object has no attribute 'timeout'

I can't understand how come there is no timeout attribute?!

In fact I am looking at the intelisense and there is no such attribute too.

Any suggestion will be greatly appreciated

Answer 1

The socket module has a timeout class. Your socket object, mysocket (of type socket.socket), does not have a timeout attribute.

Try this:

except timeout:
 print 'Request timed out!'
 mySocket.close()

Note that you should also be careful about using import * in this manner.
