Create a Network Server with Python

#python #socket #networking #syntax

To write Internet servers, we use the socket function available in socket module to create a socket object. A socket object is then used to call other functions to setup a socket server.

Now call bind(hostname, port) function to specify a port for your service on the given host.

Next, call the accept method of the returned object. This method waits until a client connects to the port you specified, and then returns a connection object that represents the connection to that client.

#!/usr/bin/python           
# This is server.py file

import socket               
# Import socket module

s = socket.socket()         
# Create a socket object
host = socket.gethostname() 
# Get local machine name
port = 12345                
# Reserve a port for your service.
s.bind((host, port))        
# Bind to the port

s.listen(5)                 
# Now wait for client connection.
while True:
   c, addr = s.accept()     
# Establish connection with client.
   print 'Got connection from', addr
   c.send('Thank you for connecting')
   c.close()                
# Output the message and Close the connection

Hands-on debugging session: instrument, monitor, and fix

Join Lazar for a hands-on session where you’ll build it, break it, debug it, and fix it. You’ll set up Sentry, track errors, use Session Replay and Tracing, and leverage some good ol’ AI to find and fix issues fast.
