Async Python Programming

asyncio enables concurrent code execution for I/O-bound tasks.

Basic async/await

import asyncio

async def fetch_data(url):
    await asyncio.sleep(1)  # Simulate API call
    return f"Data from {url}"

async def main():
    results = await asyncio.gather(
        fetch_data("url1"),
        fetch_data("url2"),
    )
    print(results)

asyncio.run(main())
