Simple chat server in Python

Add the following code to server.py and run.

# server.py
#!/usr/bin/python

import socket

sock = socket.socket()
host = 'localhost' # Change this to "" to receive connections from any host
port = 12221  # Any unreserved port but must be same as client
sock.bind((host, port))

sock.listen(5)
conn = None

while True:
   if conn is None:
       # Halts
       print ('[Waiting for connection...]')
       conn, addr = sock.accept()
       print('Got connection from', addr)
   else:
       # Halts
       print ( '[Waiting for response...]')
       print (conn.recv(1024))
       msg = input("Enter something to this client: ")
       conn.send(msg.encode('UTF-8'))

Add the following code to client.py.

# client.py
#!/usr/bin/python

import socket

sock = socket.socket()
host = 'localhost' # Change this to remote ip as necessary
port = 12221 # Any unreserved port but must be same as server

sock.connect((host, port))
print ('Connected to', host)

while True:
msg = input("Enter something for the server: ")
sock.send(msg.encode('UTF-8'))
# Halts
print ('[Waiting for response...]')
print (sock.recv(1024))
