Aiohttp
Aiohttp is an asynchronous HTTP client/server framework for Python, built on top of asyncio. It enables developers to write high-performance, non-blocking web applications and APIs by leveraging Python's async/await syntax. The library supports both client-side HTTP requests and server-side web server functionality, making it ideal for building scalable network services.
Developers should learn Aiohttp when building high-concurrency web applications, such as real-time APIs, microservices, or web scrapers, where traditional synchronous frameworks like Flask or Django might bottleneck under heavy I/O operations. It's particularly useful in scenarios requiring handling thousands of simultaneous connections efficiently, such as chat servers or IoT data ingestion systems, due to its non-blocking architecture.
