Simple Chat Server (Sockets)
đĄ Overview
Sockets are the actual low-level plumbing behind every network app you use daily. Building a simple one demystifies what 'connecting to a server' really means underneath all those APIs and frameworks.

Write a basic server using Python's 'socket' module: create a socket, bind it to a port, and listen().
Write a client that connects() to that server's IP and port.
Have the client send a text message, and the server receive and print it.
Have the server send a response back, and the client receive and print it.
Wrap the send/receive in a loop so the conversation can continue until the client types 'exit'.
đ Starter Code
import socket
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('localhost', 5000))
server.listen(1)
print('Waiting for connection...')
conn, addr = server.accept()
print('Connected:', addr)
msg = conn.recv(1024).decode()
print('Client says:', msg)đĄ Pro Tip
Test the server and client in two separate terminal windows on the same machine first (using 'localhost') â get that working before worrying about connecting across different devices/networks.
