Python inter-computer communication

Question

This whole topic is way out of my depth, so forgive my imprecise question, but I have two computers both connected to one LAN.

What I want is to be able to communicate one string between the two, by running a python script on the first (the host) where the string will originate, and a second on the client computer to retrieve the string.

What is the most efficient way for an inexperienced programmer like me to achieve this?

Answer 1

First, lets get the nomenclature straight. Usually the part that initiate the communication is the client, the parts that is waiting for a connection is a server, which then will receive the data from the client and generate a response. From your question, the "host" is the client and the "client" seems to be the server.

Then you have to decide how to transfer the data. You can use straight sockets, in which case you can use SocketServer, or you can rely on an existing protocol, like HTTP or XML-RPC, in which case you will find ready to use library packages with plenty of examples (e.g. xmlrpclib and SimpleXMLRPCServer)

Answer 2

There are about a million ways.

If I were doing it, I'd use the SocketServer library, because it's not too insane, fairly well documented, and most importantly, I've used it before.

There are a couple of examples here: http://docs.python.org/library/socketserver.html#examples
