Making two python programs communicate

Question

I have two python programs running infinitely.

The first process uses Twisted and Autobahn to receive data from a WebSocket feed. It is an infinite loop.

The second process uses a custom library to receive data from Pusher WebSocket feed. It is also an infinite loop.

I am seeking for a way to make these two processes communicate with a third process. This third process must be able to communicate bidirectionally with both processes. Hence, the third process must be able to push and receive messages from the two programs.

I tried to use multiprocessing and Queue but without success.

This is the first process:

from twisted.internet import reactor
from autobahn.twisted.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS
import json

class ClientProtocol(WebSocketClientProtocol):

    ...

    def onMessage(self, msg, binary):
        ...
        # Send data to third process
    ...

if __name__ == '__main__':
    factory = WebSocketClientFactory("wss://feed.com")
    factory.protocol = ClientProtocol
    connectWS(factory)
    reactor.run()

This is the second process:

import pusherclient
import sys, time
import json

def callback(event):
    ...
    # Send data to third process

global pusher


def connect_handler(data):
    channel = pusher.subscribe('order_book')
    channel.bind('data', callback)


...
pusher.connect()

while True:
        time.sleep(1)
