Interprocess communication between independent Python3 scripts

Question

Can we use standard multiprocessing.Queue class for communicating between independent Python3 scripts like

bash% ./aaa.py &
bash% ./bbb.py &

If no, Is there another library like standard multiprocessing module for communicating with independent scripts.

Answer 1

Take a look at the section on "Listeners and Clients" in the multiprocessing docs; unlike the higher level simpler APIs, these APIs allow you to establish connections by address and authenticate the paired process, which allows two Python scripts to cooperate without having a parent/child relationship.
