Have you had experience using asynchronous input/output in your projects?

Yes, asynchronous I/O is commonly used in Python projects to improve performance when working with operations that can block the thread, such as network requests or file operations.

Python uses the asyncio module for this purpose, allowing writing asynchronous code with async and await keywords.

Example of an async function making an HTTP request with aiohttp:

import asyncio
import aiohttp

async def fetch(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            return await response.text()

async def main():
    html = await fetch('https://example.com')
    print(html)

asyncio.run(main())

Async I/O enables efficient resource utilization by not blocking the main thread, which is especially useful for network and high-load applications.
