How Can Python's `subprocess` Module Manage Background Processes Like a Shell's '&' Operator?

Background Process Management in Python

In a desire for improved readability, you seek to convert a shell script to Python while preserving its core functionality: running processes in the background using "&". Through this process, you desire that these processes continue executing upon completion of the Python script. Exploring the concept of daemons, you stumble upon a more recommended and contemporary approach: the subprocess module.

The subprocess module provides an intuitive method for background process management. A simple example would be:

import subprocess
subprocess.Popen(["rm", "-r", "some.file"])

This command will execute rm -r some.file silently in the background without blocking the main script's execution.

To further clarify, the term "background" refers to a shell concept where processes run without blocking the shell's prompt. In this context, "background" is used synonymously with non-blocking processes.

For more complex process management scenarios, the subprocess module offers a comprehensive suite of features and functions. Refer to the official documentation for an in-depth exploration.
