How to close() server connection with key-press? (Simple networking with Socket)

So I am very new to networking and the Socket module in Python. So I watched some Youtube tutorials and found one on how to write the code for a simple server. My problem is right when the server receives data from the client, the server close() and loses connection to the client right when it receives the data. I want the server to automatically lose connection to the client but not "shutdown" or close(). I want to set it (if its possible) so that while the server is running in my Python Shell, if I want to close() the connection I use hot keys like for example "Control+E"? Here is my code so far:

#!/usr/bin/python
import socket
import sys

# Create a TCP/IP socket to listen on
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Prevent from "adress already in use" upon server restart
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

# Bind the socket to port 8081 on all interfaces
server_address = ('localhost',8081)
print ('starting up on %s port %s')%(server_address)
server.bind(server_address)

#Listen for connections
server.listen(5)

#Wait for one incoming connection
connection, client_address = server.accept()
print 'connection from', connection.getpeername()

# Let's recieve something
data = connection.recv(4096)
if data:
    print "Recived ", repr(data)

    #send the data back nicely formatted
    data = data.rstrip()
    connection.send("%s\n%s\n%s\n"%('-'*80, data.center(80),'-'*80))

# lose the connection from our side (the Server side)
connection.shutdown(socket.SHUT_RD | socket.SHUT_WR)
connection.close()
print 'Connection closed'

# And stop listening
server.close()

================================================================================== Here is the code I am using (on the server side):

#!/usr/bin/python

import socket, sys
import select

srv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

#Let's set the socket option reuse to 1, so that our server terminates quicker
srv.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

srv.bind(("localhost", 8081))
srv.listen(5)

while True:
    print "Waiting for a client to connect"
    (client, c_address) = srv.accept() #blocking wait for client
    print "Client connected"

    # Client has connected, add him to a list which we can poll for data
    client_list = [client]

while close_socket_condition == 0:
    ready_to_read, ready_to_write, in_error = select.select(client_list, [], [] , 1) #timeout 1 second

    for s in ready_to_read: #Check if there is any socket that has data ready for us

        data = client.recv(1024) # blocks until some data is read

    if data:
        client.send("echo:" + data)

    client.close()
    close_socket_condition = 1

And here is the error it is giving me when I try to send a string to the server:

  data = s.recv(1024)
  File "C:\Python27\lib\socket.py", line 170, in _dummy
    raise error(EBADF, 'Bad file descriptor')
error: [Errno 9] Bad file descriptor
