Pyro4 is version 4 of the Pyro library. It enables you to build applications in which Python remote objects can talk to each other over the network, with minimal programming effort.

You use normal Python method calls, with almost every possible parameter and return value type, and Pyro takes care of locating the right object on the right computer to execute the method. It is designed to be very easy to use, and to, generally, be non-obtrusive.

Pyro also provides a set of powerful features that enables you to build distributed applications rapidly and effortlessly. Pyro is written in 100% pure Python and therefore runs on many platforms and Python versions.
