run persistent py script in background (good for flask)

To run a persistent Python script in the background, particularly for Flask, you can follow these steps:

1. Import the necessary modules:

import subprocess

1. Define a function to start the script in the background:

def start_background_process():
    subprocess.Popen(["python", "your_script.py"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE, shell=True)

1. Call the function in your Flask application:

if __name__ == '__main__':
    start_background_process()
    app.run(debug=True)

These steps will allow you to run a persistent Python script in the background while using Flask.
