What are some advanced topics in asyncio that I should know about?

Some advanced topics in asyncio include creating custom event loops, using asyncio with threads, and handling cancellation.

Can you explain how to create a custom event loop?

Sure! You can create a custom event loop by subclassing asyncio.AbstractEventLoop and implementing the required methods.

What about using asyncio with threads? How does that work?

Using asyncio with threads involves running the event loop in a separate thread and using asyncio.run_coroutine_threadsafe to schedule coroutines.

Are there any best practices for handling cancellation in asyncio?

Yes, it's important to use asyncio.CancelledError to handle cancellations gracefully and ensure resources are cleaned up.
