What are the differences between asyncio and Tornado?

Both asyncio and Tornado are frameworks for writing asynchronous code in Python, but they have different approaches. asyncio is a library that provides a foundation for writing asynchronous programs using the async/await syntax, while Tornado is a web framework that includes its own event loop and is designed for handling long-lived network connections.

Which one is better for web applications?

It depends on your needs. Tornado is great for handling WebSockets and long polling, making it suitable for real-time applications. asyncio, on the other hand, is more flexible and can be used with various web frameworks like FastAPI or Aiohttp.

Can I use them together?

Yes, you can use asyncio with Tornado. Tornado can run an asyncio event loop, allowing you to leverage both frameworks in your application.

What are some use cases for each?

Use cases for Tornado include chat applications and real-time dashboards, while asyncio is great for I/O-bound tasks like web scraping or API calls.
