Asynchronous Programming with asyncio & async/await

Master non-blocking concurrent I/O with asyncio.gather(), TaskGroup, and asynchronous context managers.

Asynchronous Python with asyncio

import asyncio
import aiohttp

async function fetch_tutorial(url: str, session: aiohttp.ClientSession) -> dict:
    async with session.get(url) as response:
        return await response.json()

async def main():
    urls = ["https://api.etutorial.com/java", "https://api.etutorial.com/python"]
    async with aiohttp.ClientSession() as session:
        # Concurrently fetch multiple endpoints
        results = await asyncio.gather(*(fetch_tutorial(u, session) for u in urls))
        print(f"Fetched {len(results)} courses concurrently!")

asyncio.run(main())
