Gevent
Gevent is a Python library that provides a high-level synchronous API for asynchronous I/O operations, built on top of the libev or libuv event loops and greenlets (lightweight coroutines). It enables developers to write concurrent code in a synchronous style while achieving high performance through cooperative multitasking, making it particularly effective for network applications like web servers and real-time systems.
Developers should learn Gevent when building scalable network applications in Python that require handling many concurrent connections efficiently, such as web servers, chat servers, or API backends. It simplifies asynchronous programming by allowing the use of blocking-style code without the complexity of callbacks, making it easier to maintain and debug compared to traditional async frameworks like asyncio in certain contexts.
