Prevent vscode from exiting the Python interpreter a script completes

The way I have used Python for years (through Spyder, directly from a bash terminal, etc.) is to execute a script in interactive mode such that once it's done, you can interact with it, e.g.:

python -i script.py

VSCode's debugger does not give a way to get this behavior currently. And it seems like I am not the only one looking for it:

• https://stackoverflow.com/questions/54609806/how-to-prevent-vscode-from-exiting-python-environment-after-running-code
• https://www.reddit.com/r/vscode/comments/8uv8xc/how_to_keep_python_running_after_script_execution/
• https://github.com/microsoft/vscode-python/issues/5497

One workaround is to put a breakpoint at the end of your file, but this requires extra work.

Another workaround is to add "env": {"PYTHONINSPECT": "true"}, to the launch configuration with integratedTerminal, but this doesn't work properly as any input is captured and newlines aren't treated properly while printing, which makes it pretty unusable.

I could see at least two potential solutions (the first would be better I think):

1. Make it so that in PYTHONINSPECT mode, the terminal could be interacted with properly, possibly by adding a new inspectOnExit or something that ran in -i / PYTHONINSPECT mode and returned proper input/output when the script completes. Based on https://github.com/microsoft/vscode-python/issues/5497 it sounds like this is a no-go, though.
2. Add a stopOnExit debug option to mirror stopOnEntry in the debugger. This way at least variables could be inspected using the vscode debugger.

El issue no menciona archivos de implementación ni pruebas. Comienza revisando la discusión enlazada y el comportamiento existente del depurador stopOnEntry, y luego compara los enfoques interactivos propuestos PYTHONINSPECT y stopOnExit con el issue 5497. Done debería proporcionar una experiencia utilizable de inspección posterior al script sin requerir un breakpoint al final.
