Pyro4

Pyro4 is a robust and mature distributed object middleware for Python, enabling remote method calls (RPC) between Python applications. It reached its last major release with 4.82 in August 2020 and is now in a maintenance-only mode, with active development having shifted to its successor, Pyro5. Pyro4 offers features like name server discovery, object exposure, and various serialization options, making it suitable for creating distributed systems, but users should be aware of its end-of-life status for new feature development.
