Handling a timeout error in Python sockets

I am trying to figure out how to use the try and except to handle a socket timeout.

from socket import *

def main():
    client_socket = socket(AF_INET,SOCK_DGRAM)
    client_socket.settimeout(1)
    server_host = 'localhost'
    server_port = 1234
    while(True):
        client_socket.sendto('Message',(server_host,server_port))
        try:
            reply, server_address_info = client_socket.recvfrom(1024)
            print reply
        except socket.Timeouterror:
            # More code

The way I added the socket module was to import everything, but how do I handle exceptions?

In the documentation it says you can use socket.timeouterror, but that doesn't work for me. Also, how would I write the try exception block if I did import socket? What is the difference in the imports?
