What are some advanced techniques for web scraping using Python 3.10 and asyncio?

You can use libraries like aiohttp for asynchronous requests, and BeautifulSoup for parsing HTML. Would you like to see a code example?

Yes, please provide a code example that demonstrates this.

Here's a simple example:

import aiohttp
import asyncio
from bs4 import BeautifulSoup

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

async def scrape(url):
    html = await fetch(url)
    soup = BeautifulSoup(html, 'html.parser')
    return soup.title.string

url = 'https://example.com'
result = asyncio.run(scrape(url))
print(result)

This code fetches the title of a webpage asynchronously.

How can I handle multiple URLs at once using this approach?

You can modify the scrape function to accept a list of URLs and use asyncio.gather to run multiple fetches concurrently. Would you like to see that implementation?
