What are some examples of using async I/O libraries?

Can you give me some examples of using async I/O libraries in Python?

Sure! One popular async I/O library in Python is asyncio. You can use it to handle asynchronous tasks like web scraping or handling multiple network connections.

How do I use asyncio to make an HTTP request?

You can use the aiohttp library along with asyncio. Here's a simple example:

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('http://example.com')
    print(html)

asyncio.run(main())

What are the benefits of using async I/O?

The main benefits include improved performance for I/O-bound tasks, better resource utilization, and the ability to handle many connections simultaneously without blocking.

Are there any other async libraries I should know about?

Yes, besides asyncio and aiohttp, you might want to check out trio and curio, which offer different approaches to async programming.
