Gevent is a great library that uses greenlets (a Python co-routine library) to enable asynchronous I/O, while providing  API that looks like normal synchronous API, so it’s  easier to use and understand.  The async magic is done automatically by Gevent, which is running an event loop on background and switching between coroutines as necessary.

This approach can be very useful for concurrent applications, which spend a lot of time in waiting for I/O.  Like web applications – so Gevent is popular there.  For certain type of workloads it can be quite useful – it can enable higher concurrency,  while using less resources (greenlet is much lighter then thread or  process).
