title: Two Raspberries communicating each other
body: <p>I'm due to prepare two raspberries talking each other through python program. Before starting I would understand which is the easiest way to do so. More precisely, Raspberry A receives an input to GPIO. A python code read the status of GPIO and sends an input to raspberry B that is read by an other python code. Raspberry B python code sends back to Raspberry A a message for doing something. The two raspberries are on the same network.
  How can I implement the communication through network between the two raspberries? What should I use for sending and receiving inputs over network?
  Many thanks for the help</p>
