gevent 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.
Features include:
- Fast event loop based on libev or libuv.
- Lightweight execution units based on greenlets.
- API that re-uses concepts from the Python standard library (for examples there are events and queues).
- Cooperative sockets with SSL support
- Cooperative DNS queries performed through a threadpool, dnspython, or c-ares.

- TCP/UDP/HTTP servers
- Subprocess support (through gevent.subprocess)
