How can I use asyncio with other libraries in Python?

You can use asyncio with libraries like aiohttp for asynchronous HTTP requests or databases like asyncpg for PostgreSQL.

Can you give me an example of using aiohttp with asyncio?

Sure! 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 about using asyncio with a database?

You can use asyncpg for PostgreSQL. Here's a quick example:

import asyncio
import asyncpg

async def fetch_data():
    conn = await asyncpg.connect(user='user', password='password', database='db', host='127.0.0.1')
    rows = await conn.fetch('SELECT * FROM my_table')
    await conn.close()
    return rows

asyncio.run(fetch_data())
