[Python-Dev] quit() on the prompt (original) (raw)

Ian reproposed:

class Quitter(object):
     def __init__(self, name):
         self.name = name
     def __repr__(self):
         return 'Use %s() to exit' % self.name
     def __call__(self):
         raise SystemExit()

The one change I would suggest is the string used in repr.

Some of the objections to the current behavior boil down to "If it knows what I mean, why didn't it do it?" We probably can't explain first-class callables in a short message, but we could emphasize that it has to be called. Perhaps

     def __repr__(self):
         return 'Calling %s() will exit python' % self.name
