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
