How to create 2 processes in python with access to a file?

Question

Python

Greetings.
there is such a task - you need to create two processes and share access to the .txt file.
The task is to output lines from a .txt file using two processes without violating the order of the lines.
I'm trying to smoke the documentation, but "cho-that is complicated" (c). Can someone explain popularly how these processes are created? and how to describe their interaction?

They want the processes from you to work not in parallel, but in a pipeline .
