How does cancellation work in asyncio?

In asyncio, cancellation allows you to stop a running coroutine. You can use the cancel() method on a task.

What happens if a coroutine is cancelled?

When a coroutine is cancelled, it raises a CancelledError exception. You can handle this exception to clean up resources.

Can I check if a task is cancelled before it finishes?

Yes, you can check the task's status using the done() method. If it returns True, the task has finished or was cancelled.

Are there any best practices for cancelling tasks?

It's best to ensure that your coroutines can handle cancellation gracefully, using try-except blocks to catch CancelledError.
