They are instances of the same type
>>> import inspect
>>> type(quit) is type(exit)
True
>>> print(inspect.getsource(type(quit)))
class Quitter(object):
 def __init__(self, name, eof):
 self.name = name
 self.eof = eof
 def __repr__(self):
 return 'Use %s() or %s to exit' % (self.name, self.eof)
 def __call__(self, code=None):
 # Shells like IDLE catch the SystemExit, but listen when their
 # stdin wrapper is closed.
 try:
 sys.stdin.close()
 except:
 pass
 raise SystemExit(code)
There is no difference, except for the name attribute and the repr() text:
>>> exit.name, exit.eof, exit
('exit', 'Ctrl-D (i.e. EOF)', Use exit() or Ctrl-D (i.e. EOF) to exit)
>>> quit.name, quit.eof, quit
('quit', 'Ctrl-D (i.e. EOF)', Use quit() or Ctrl-D (i.e. EOF) to exit)
