how to disable Python pdb's Quitting pdb will kill the process. Quit anyway [y/n]? prompt
I'm running Python 3.14 in Linux. I have script with a breakpoint() in it, so when I run $ python my_script.py, it will take me into the (Pdb) prompt. Then, if I want to exit, I type q or do CTRL+D. It then shows this prompt:
Quitting pdb will kill the process. Quit anyway [y/n]?
Is there any way to disable this warning? Meaning I want to automatically do the "y" option and kill the process when I type q or do CTRL+D.

This behaviour is new in Python 3.14. It is defined in the pdb.Pdb.do_quit method, with the following comment:
Show prompt to kill process when in 'inline' mode and if pdb was not started from an interactive console. The attribute sys.ps1 is only defined if the interpreter is in interactive mode.
If neither of these conditions is met, pdb delegates to the bdb.Bdb.set_quit method, which does not contain a prompt. The Python documentation says:
The mode argument specifies how the debugger was invoked. It impacts the workings of some debugger commands. Valid values are
'inline'(used by the breakpoint() builtin),'cli'(used by the command line invocation) orNone(for backwards compatible behaviour, as before the mode argument was added).
So, one solution would be overriding breakpoint() so that it invokes pdb.Pdb with mode=None, restoring the pre-3.14 quit behaviour. However, I'm not sure how to properly do that. As a hack, inserting sys.ps1 = '>>> ' at some point before your breakpoint() invocation should also work.
