What are tasks and futures in asyncio?

Can you explain what tasks and futures are in asyncio?

Sure! In asyncio, a 'Future' is an object that represents a result that hasn't been computed yet. A 'Task' is a subclass of Future that wraps a coroutine.

How do I create a task in asyncio?

You can create a task using the asyncio.create_task() function, passing in the coroutine you want to run.

What happens if I try to access a future before it's done?

If you try to access a Future's result before it's done, it will block until the result is available, unless you use asyncio.wait() or similar.

Can I cancel a task in asyncio?

Yes, you can cancel a task by calling its cancel() method, but you need to handle the cancellation properly in your coroutine.
