So I would like to be able to ask for confirmation when I receive a C-c,
and continue if the answer is "N/n".

I'm already using an exception handler set with sys.excepthook, but I
can't make it work with the confirm_exit, because it's going to quit in
any case..

A possible solution would be to do a global "try/except
KeyboardInterrupt", but since I already have an excepthook I wanted to
use this.  Any way to make it continue where it was running after the
exception is handled?


def confirm_exit():
    while True:
        q = raw_input("This will quit the program, are you sure? [y/N]")
        if q in ('y', 'Y'):
            sys.exit(0)
        elif q in ('n', 'N'):
            print("Continuing execution")
            # just go back to normal execution, is it possible??
            break


def _exception_handler(etype, value, tb):
    if etype == KeyboardInterrupt:
        confirm_exit()
    else:
        sys.exit(1)


def set_exception_handler():
    sys.excepthook = _exception_handler
