Python - Wanting to pass data from one script to another while they are both running

Question

So I'm making a Discord Bot that posts when a person goes live on Twitch.tv. At the moment I have a Python program that runs the bot and a program that runs a mini server to receive the data from the Twitch server(webhook). I am unsure on how to pass on the data I receive from my server to the discord bot. Both programs have to be running at the same time.

DiscordBot

import discord


client = discord.Client()




async def goes_live(data):
    print(data)
    print('Going Live')
    msg = '--- has gone live'
    await client.send_message(discord.Object(id='---'), msg)


@client.event
async def on_message(message):
    if message.author == client.user:
        return

    message.content = message.content.casefold()


@client.event
async def on_ready():
    print('Logged in as')
    print(client.user.name)
    print(client.user.id)
    print('------')


client.run('---')

Web server

import web

urls = ('/.*', 'hooks')

app = web.application(urls, globals())


class hooks:

    def POST(self):
        data = web.data()
        print("")
        print('DATA RECEIVED:')
        print(data)
        print("")

        return 'OK'

    def GET(self):
        try:
            data = web.input()
            data = data['hub.challenge']
            print("Hub challenge: ", data)
            return data
        except KeyError:
            return web.BadRequest



if __name__ == '__main__':
    app.run()

Since both your programs are in python, and if they are related to each other enough that they always run together, you can simply use multiprocessing module: have each one of the programs run as a multiprocessing.Process instance, and give each one of them one end of a multiprocessing.Pipe, that way you can exchange informations between processes.

The architecture would look something like that main.py:

# main.py
from multiprocessing import Process, Pipe
import program_1
import program_2

program_1_pipe_end, program_2_pipe_end = Pipe()

process_1 = Process(
    target = program_1.main,
    args = (program_1_pipe_end,)
    )

process_2 = Process(
    target = program_2.main,
    args = (program_2_pipe_end,)
    )

process_1.start()
process_2.start()
#Now they are running
process_1.join()
process_2.join()

# program_1.py and program_2.py follow this model

# [...]

# instead of if __name__ == '__main__' , do:
def main(pipe_end):
    # and use that pipe end to discuss with the other program
    pass

You can find the Pipe documentation here, (inside multiprocessing documentation).
