Re: Is it possible (and wise) to extend the None-type ?

[Stef Mientki]

<snip>

Alternative (if you *really* want to save the explicit test) is to
attach the behaviour modification to the *relevant* class:

class NonEvent(Event):
   def do_nothing(self):
      pass
   skip = jump = hop = waltz = saunter = do_nothing
   def __len__(self):
      return 0
NON_EVENT = NonEvent()
del NonEvent

# later:

def amethod(self, event=NON_EVENT):
   if event: # still works thanks to __len__ above
      event.skip()
   # now can avoid test, if desired
   event.skip()

thanks guys, the Null, Dummy, Skipper, Nonevent class works great

HTH ... BTW, ever heard of PEP 8?

I guess Python is missing some kind of CSS ;-)

cheers,
Stef
