Welcome to the Advanced Networking section of our Python tutorials! This guide dives deeper into networking concepts, building on foundational knowledge to explore more complex applications. Whether you're mastering socket programming, async IO, or network security, here's a structured overview to help you progress.

Key Topics Covered

  • 📡 Socket Programming: Creating custom network protocols with socket module
  • 🔄 Asynchronous Networking: Using asyncio for non-blocking network operations
  • 🔐 Security Protocols: Implementing SSL/TLS with ssl module
  • 🧩 Network Troubleshooting: Debugging with socket.error handling
  • 🌐 Advanced Web Requests: requests library for HTTP/HTTPS with headers and proxies

Example: Asynchronous TCP Server

import asyncio

async def handle_client(reader, writer):
    data = await reader.read(100)
    message = data.decode()
    print(f"Received: {message}")
    writer.write(f"Echo: {message}\n".encode())
    await writer.drain()
    writer.close()

async def main():
    server = await asyncio.start_server(handle_client, '127.0.0.1', 8888)
    async with server:
        await server.serve_forever()

asyncio.run(main())
