As well as Ctrl-D, EOF, which is a standard way to exit most Unix programs.
(Or as close as anything in Unix comes to a standard UI.)

Do you still believe that quit/exit is REQUIRED?
To be pedantic, we have at least seven ways:
- EOF (Ctrl-D on Unix, Ctrl-Z ENTER on Windows);
- calling quit() or exit();
- raise SystemExit;
- call sys.exit()
- call os._exit();
- call os.abort();
- write your own custom quitter object that exits on simply being
printed, e.g.:
class Bye:
def __repr__(self):
sys.exit(0)
bye = Bye()
Four of these are intended for programmatic use, but they work interactively
as well. At least two of them shouldn't be used unless you know what you are
doing (os._exit and os.abort).

os._exit and os.abort (especially the second) could legitimately be described
as "crashing out". The others, not within a million miles of it.

Thousands of Python programmers on Windows successfully learned to use Ctrl-Z
ENTER back in the days of Python 1.5, before quit/exit were added as a
convenience for beginners, and many of them probably still use it.
Yet again you assume that because YOU don't do something, nobody else in the
world could possibly do it.

This thread would be a lot less frustrating if you would enter into it with a
spirit of open-minded enquiry rather than an overbearing sense of superiority
that anything others do that you don't must be worthless.
