Python socket — chat server and client with code example Python socket — chat server and client with code example 48 Comments Socket based chat application In our previous article on socket programming in python we learned about the basics of creating a socket server and client in python.

In this post we are going to write a very simple chat application in python that is powered by sockets.

Your Answer

The chat application we are going to make will be more like a chat room, rather than a peer to peer chat. So this means that multiple users can connect to the chat server and send their messages. Every message is broadcasted to every connected chat user. The construction is as simple as the theory.

Code The code consists of 2 python scripts.

First is the server and the other is the chat client. Chat server The chat server does the following things 1. Accept multiple incoming connections for client.

Read incoming messages from each client and broadcast them to all other connected clients.

Here is the code of the chat server. It server opens up port to listen for incoming connections. The chat client must connect to this same port. You can change the port number if you want. The server handles multiple chat clients with select based multiplexing.

The select function monitors all the client sockets and the master socket for readable activity. If any of the client socket is readable then it means that one of the chat client has send a message. So if the master socket is readable, the server would accept the new connection.

If any of the client socket is readable, the server would read the message, and broadcast it back to all clients except the one who send the message. The following function broadcasts the message to all chat clients. Rest of the program is quite self explanatory.

Here is the full code of the chat client. Data recieved from client, process it try: The client is based on the telnet program in python.
