#MULTI CHAT CLIENT PYTHON HOW TO#

I suggest using different ports on each side of the communication.

S.sendto(byteOut,otherIP) # Send Server Reply back

By now, we have created a method that helped us understand handling the specific clients’ requests.

#MULTI CHAT CLIENT PYTHON HOW TO#

Python program to implement client side of chat room. Connect Multiple Clients in Python We will keep the core concept intact we must learn how to handle the multiple threads or clients in Python concurrently. At the end of this tutorial you will have a working game where moving a rectangle on one client will move it on the other. I go over how to send valuable information from the client to the server and vice versa. cmdOut = 'Hello other side of the communication'īyteOut = bytes(cmdOut.encode('utf-8')) # Convert Server reply to bytes then any computer from these 99 nodes can act as a server, and the remaining. This python online game tutorial covers connecting multiple clients to a server. If you want a messenger application you need a server and a client on both sides of the communication. But not a messenger app as messages are only received. # here you can start a thread if multiple users connect simultaneously Now let’s bind the host and port to the socket server we created above in the program. ServerSocket socket.socket() host 127.0.0.1 port 1233 ThreadCount 0. So, the server provides a sort of chatting room. Along with this let’s declare the host and port on which we need to communicate with clients. The server broadcasts any messages from a client to the other participants. Now there is no reason to use the s.accept and s.listen functions as the following function already does all that is needed: while True:ĭata,addr = s.recvfrom(512) # number of bytes in the message Now let’s create a socket connection using the socket () of the socket library. S.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1) # reuse the port otherwise it will be blocked if the connection is not closed The diiference between SOCK_DGRAM (UDP) and SOCK_STREAM (TCP) is explained here: What is SOCK_DGRAM and SOCK_STREAM? import socket

First you need to decide what connection type you plan to use:įor a simple chat application I suggest UDP.
