What is the best way to organize the interaction of two python scripts?

Question

Python

I see a chain like this: the first script works in the background, and every n times it calls to a certain "buffer" where the string values ​​sent by the user are stored. At a time, the script takes 1 value, after which it removes it from the "buffer". Then the script somehow launches the second script and passes this value to it, in response somehow receives the processed value, processes it and reports the result to the user. What is the best way to organize such a chain?

Answer 1

I would do this if on my knee:
Script_1 -> MongoDB -> Script_2
More adequately:
Script_1 -> rabbitmq or redis -> Script_2
In the first case, in the middle is a nosql base that does not require a preliminary object structure.
In the second case, the message broker.

Answer 2

websocket. Those. microservice
Connecting a couple of lines. One line communication
