Here's the client portion:

import socket
import time

# Prompt user for host IP and port number.
host = raw_input("What IP: ")
port = raw_input("What port: ")

# Strip any whitespace and make sure port is an int.
host = str.strip(host)
port = str.strip(port)
port = int(port)

def msg():
    msg = raw_input("Enter command to send to the server: ")
    msg = str.strip(msg)
    print "\nYou sent:", msg
    return msg

def send(msg):
    ## Send the data to the server.
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((host, port))
    s.send(msg)
    s.close()

send(msg())
