asyncio

What problem does it solve?

Python's asyncio enables writing concurrent code using async/await, primarily to manage I/O-bound tasks without blocking the event loop, leading to more scalable Python applications.

Core Features & Use Cases

• Async/await syntax for readable concurrent code
• Event loop, tasks, and primitives (locks, semaphores, queues)
• Async HTTP clients/servers with aiohttp and FastAPI async patterns
• Integration with databases, WebSocket support, streaming, and background tasks

Quick Start

Define async functions and run them with asyncio.run() to start the event loop and execute concurrent tasks.
