[issue41096] Need command to exit PDB interactive shell

[Kerrick Staley]

New submission from Kerrick Staley <kerrick at kerrickstaley.com>:

In PDB, when you use "interact" to enter an interactive shell, the only way to exit that shell is to send an end-of-transmission (Ctrl+D) character. In some environments, such as Jupyter, this is awkward to do. Here is a StackOverflow post where a user encountered this issue:

I think that the user should be able to type quit() in order to exit the interactive Python shell and go back to the PDB shell, similar to a regular interactive Python session. I think you should also support exit() because the Python shell supports that one as well (quit() and exit() do the same thing, I think the alias exists to help discoverability for new users).

I confirmed this issue on Python 3.6.9 and 3.8.3.
