Passing data between separately running Python scripts

Question

If I have a python script running (with full Tkinter GUI and everything) and I want to pass the live data it is gathering (stored internally in arrays and such) to another p

Answer 1

you can use multiprocessing module to implement a Pipe between the two modules. Then you can start one of the modules as a Process and use the Pipe to communicate with it. The best part about using pipes is you can also pass python objects like dict,list through it.

Ex: mp2.py:

from multiprocessing import Process,Queue,Pipe
from mp1 import f

if __name__ == '__main__':
    parent_conn,child_conn = Pipe()
    p = Process(target=f, args=(child_conn,))
    p.start()
    print(parent_conn.recv())   # prints "Hello"

mp1.py:

from multiprocessing import Process,Pipe

def f(child_conn):
    msg = "Hello"
    child_conn.send(msg)
    child_conn.close()
