How does asyncio compare to other concurrency models in Python?

Asyncio is designed for asynchronous programming, allowing for non-blocking I/O operations. It generally performs better than threading for I/O-bound tasks but may not be as efficient for CPU-bound tasks compared to multiprocessing.

Can you explain why asyncio is better for I/O-bound tasks?

Asyncio uses an event loop to manage tasks, which allows it to handle many I/O operations concurrently without the overhead of multiple threads. This makes it more efficient for tasks like web scraping or network requests.

What are some examples of when to use asyncio?

You should use asyncio for applications that require handling many simultaneous I/O operations, such as web servers, chat applications, or any scenario where you need to wait for external resources.

Are there any downsides to using asyncio?

Yes, asyncio can introduce complexity in code structure and may not be suitable for CPU-bound tasks, where multiprocessing might be a better choice.
