Pull Request Overview

This PR introduces a simple socket communication implementation with a server that can handle a single client connection. The implementation demonstrates basic TCP socket programming concepts including server setup, client connection, and echo functionality.

• Adds a complete socket server and client implementation in Python
• Includes comprehensive documentation with usage instructions
• Updates the main repository README to reference the new implementation

The documentation incorrectly states the port as 12345, but the actual code uses port 65432. This should be updated to reflect the correct port number.

Suggested change

	This will start the server on `localhost` and listen on a predefined port (usually `localhost:12345` unless configured otherwise).

The server only handles one client connection and exits after that client disconnects. Consider wrapping the accept() call in a loop to handle multiple sequential connections.

Suggested change

	conn, addr = s.accept() # Wait for a connection
	with conn: # conn is a new socket object usable to send and receive data
	print(f"Connected by {addr}") # Accept the connection
	while True: # Loop to handle incoming data
	data = conn.recv(1024) # Receive data from the connection
	if not data:
	break
	conn.sendall(data) # Echo the received data back to the client
	while True: # Loop to handle multiple sequential connections
	conn, addr = s.accept() # Wait for a connection
	with conn: # conn is a new socket object usable to send and receive data
	print(f"Connected by {addr}") # Accept the connection
	while True: # Loop to handle incoming data
	data = conn.recv(1024) # Receive data from the connection
	if not data:
	break
	conn.sendall(data) # Echo the received data back to the client

The server doesn't handle potential socket exceptions that could occur during recv() operations. Consider adding error handling for better user experience.

Suggested change

	data = conn.recv(1024) # Receive data from the connection
	if not data:
	break
	conn.sendall(data) # Echo the received data back to the client
	try:
	data = conn.recv(1024) # Receive data from the connection
	if not data:
	break
	conn.sendall(data) # Echo the received data back to the client
	except (socket.error, ConnectionResetError) as e:
	print(f"Socket error occurred: {e}") # Log the error
	break
