Chatting Application Based on UDP Socket Programming

A Python-based chat application utilizing UDP Socket Programming with a Tkinter GUI for real-time communication between a server and multiple clients. It supports lightweight messaging, multi-client connections, threading for non-blocking I/O, and message broadcasting.

Features

• UDP Protocol for fast, lightweight communication.
• Multi-client Support for simultaneous messaging.
• Graphical User Interface (GUI) built with Tkinter.
• Threaded Operations to maintain a responsive interface.
• Message Broadcasting by the server to all connected clients.

Requirements

• Python 3.6 or later
• Required libraries:
  • socket
  • threading
  • tkinter

How to Use

Running the Server

1. Run server.py.
2. The server GUI will open, displaying message logs and providing an input box for messages.

Running the Client

1. Run client.py.
2. Enter a unique port number for the client connection.
3. The client GUI will open, allowing messages to be sent and received.

How It Works

1. The server listens for client messages and broadcasts responses to all connected clients.
2. Each client sends messages to the server and receives broadcasts.
3. Threading ensures smooth GUI operation without blocking network tasks.

Testing Scenarios

1. Single Client Interaction:
   • A client sends a message to the server, and the server replies.
2. Multiple Client Interaction:
   • Multiple clients connect, send messages, and receive broadcasts.

File Structure

• server.py: Manages server operations, client connections, and message broadcasting.
• client.py: Handles client connections, sending messages, and receiving broadcasts.
