Yes : sys.exit (value)

See the library docs for details.

However, IMO this is normally the wrong thing. I would normally raise
an exception, and the outer level of processing would have a try block
that catches all exceptions (by name for those which can be
anticipated) reporting details of why the program stopped.

Should you decide that later that you only want to abort part of your
app (e.g. to go back to the main menu), an exception can handle this
quite naturally.
