How can I make asynchronous requests in Python?

You can use the asyncio library along with aiohttp to make asynchronous HTTP requests in Python.

Can you show me a simple example?

Sure! Here's a basic 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():
    urls = ['http://example.com', 'http://example.org']
    tasks = [fetch(url) for url in urls]
    results = await asyncio.gather(*tasks)
    print(results)

asyncio.run(main())

What if I want to handle errors in the requests?

You can use a try-except block within the fetch function to handle exceptions. Here's an updated example:

async def fetch(url):
    try:
        async with aiohttp.ClientSession() as session:
            async with session.get(url) as response:
                response.raise_for_status()  # Raise an error for bad responses
                return await response.text()
    except Exception as e:
        print(f'Error fetching {url}: {e}')
