EDIT: Refresh links and code format.
Hi there! Welcome to the forums! 
It just so happens I have a bit of code I use in a gateway timer script. I use it to display data on an EZAutomation Marquee Display.
The message string is generated through SQLTag expressions. This lets me see what the message format looks like and is a bit easier to troubleshoot rather than generating it within the script. 
import socket
pointer = "[]3701_Rampf/Marquee/Message Pointer" # SQLTag stroing pointer value
pointerval = system.tag.getTagValue(pointer) # Get Value of pointer SQLTag
if pointerval < 1: # Set initial limits of pointer value
pointerval = 1
if pointerval > 3:
pointerval = 1
tagname = "[]3701_Rampf/Marquee/Message"+ str(pointerval) # Grab message by pointer value (ex. Message1, Message2, Message3, etc)
val = system.tag.getTagValue(tagname) # Messages are generated elsewhere through Tranaction Groups and expresions.
HOST = '192.168.140.206' # The remote host
PORT = 49999 # Remote host's port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Create a socket
s.connect((HOST, PORT)) # Connect the socket
s.send(val) # Send Message
s.close()
pointerval += 1 # Increment pointer value
system.tag.writeToTag(pointer,pointerval) # Write pointer value back to its SQLTag
