This library allows your Java program to interface very easily with the Python world. It uses the Pyro protocol to call methods on remote objects. (See https://pyro5.readthedocs.io/). Pyrolite only implements part of the client side Pyro library, hence its name 'lite'... So if you don't need Pyro's full feature set, Pyrolite may be a good choice to connect java or .NET and python. Version 5.0 changes: support Pyro5 wire protocol. Dropped support of Pyro4 (stick to version 4.xx for that).

There is a newer version: 5.1
