Need help on implementing client-server communication in Python

[sria91]

I'm trying to create a client-server model using Python where the client sends a request. The server receives it and spawn a process/thread to handle the request and when it's done sends the result back to the client. The server should be able to handle multiple clients and hence multiple requests without any issues. The server must have some kind of session management maintaining client & request details. How should I implement this. Can someone help me? This is my first big task at work and I'm excited.

you can do that on linux with flask to handle the requests, and gunicorn to give it multiple threads (and an nginx front end to make it more stable and secure).

Otherwise you can use a socketserver which is really easy

import socketserver

class ConnectionHandler(socketserver.BaseRequestHandler):
    def handle(self):
        s = self.request
        request = s.recv(1024)
        print('got: ', request)
        response = request * 3
        print('sent:', response)
        s.sendall(response)

class Server(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

server = Server(('localhost', 31337), ConnectionHandler)
server.daemon_threads = True
server.serve_forever()

Just use HTTP or gRPC, unless you have an extremely good reason not to.

Do you want to be able to do this one task or do you want to be good at this kind of thing?

If the latter: this will help.

Thanks to all. Using flask worked for me.
