What is Asyncio?

A Python library for writing concurrent code using async/await syntax for non-blocking I/O operations.

Asyncio enables cooperative multitasking using coroutines. Functions defined with async def can use await to pause execution while waiting for I/O, allowing other coroutines to run. This is ideal for web servers, API clients, and database queries.

Key components include the event loop, coroutines, tasks, and futures. Popular async frameworks include FastAPI, aiohttp, and Tornado.
