What literature would you recommend on interprocess communication in Python?

Question

Python

Hello.
Please advise examples of the implementation of interprocess communication in Python 3:
- semaphore
- shared memory
Googled on shared memory, everywhere they suggest simply passing data as parameters. And my goal is different: at the end of the process, "hang out" a flag for another process that you can kill this child process and cut off the connection.
UPD: well, and, accordingly, to work with all this business in the service process-dispatcher. Therefore, the descriptor must also fit into the shared memory.

Answer 1

I will advise the " Sharing state between processes " section of the official documentation.
