asyncio vs gevent: What are the differences?
asyncio: Asynchronous I/O, event loop, coroutines and tasks. This module provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives; gevent: Coroutine network library for Python. It is a coroutine -based Python networking library that uses greenlet to provide a high-level synchronous API on top of the libev or libuv event loop.
asyncio and gevent are primarily classified as "Microframeworks (Backend)" and "Web Servers" tools respectively.
