When should I use Futures instead of asyncio?

When should I use Futures instead of asyncio?

You should use Futures when you need to run blocking code in a separate thread or process, while asyncio is better for non-blocking I/O.

Can you give me an example of using Futures?

Sure! You can use concurrent.futures.ThreadPoolExecutor to run a blocking function in a separate thread.

What about asyncio? How does it handle tasks?

Asyncio uses an event loop to manage tasks, allowing you to run multiple I/O-bound operations concurrently without blocking.

Are there any performance differences between the two?

Yes, asyncio is generally more efficient for I/O-bound tasks, while Futures can be better for CPU-bound tasks when using threads.
