How to exit out of container shell from python cli

I am running python within a container.

The goal is to exit out of the container from within the running python code after receiving the input value quit. I tried the below code:

import subprocess

def qq():
    while True:
        choice = ""
        choice = input("Type \"quit\" to exit container> ")
        if choice == 'quit':
            print("Exiting container")
            subprocess.call("exit", shell=True)
            break
        else:
            print("Invalid input.")

qq()

After I docker exec and bash into the container, and run the above code, following is the output:

root@container:/pyScript#
root@container:/pyScript# python3 kwit.py
Type "quit" to exit container>
Invalid input.
Type "quit" to exit container> quit
Exiting container
root@container:/pyScript#
root@container:/pyScript#

Right now, the input quit takes me back to the container shell.

I would like the quit input to exit out of the my python's prompt and take me straight back to the docker host (instead of the container)
