asyncio
Python asyncio - Async/Await Concurrency
Overview
Python's asyncio library enables writing concurrent code using async/await syntax. It's ideal for I/O-bound operations like HTTP requests, database queries, file operations, and WebSocket connections. asyncio provides non-blocking execution without the complexity of threading or multiprocessing.
Key Features:
- async/await syntax for readable concurrent code
- Event loop for managing concurrent operations
- Tasks for running multiple coroutines concurrently
- Primitives: locks, semaphores, events, queues
- HTTP client/server with aiohttp
- Database async support (asyncpg, aiomysql, motor)
- FastAPI async endpoints
- WebSocket support
- Background task management
