If I had to choose built-in names, though, I'd prefer "property", "propset", "propdel". Another possibility that seems reasonable (perhaps a bit better) would be:
class Thing(object): @property def attribute(self): return 42 @property.set def attribute(self, value): self.ignored = value @property.delete def attribute(self): pass +1 on this spelling if possible. Though based on Guido's original recipe it might have to be written as:: @property.set(attribute) def attribute(self, value): self.ignored = value It can be written as Fred suggested: see http://groups.google.co.uk/group/comp.lang.python/browse_thread/thread/b442d08c9a019a8/8a381be5edc26340
However that depends on hacking the stack frames, so the implementation probably isn't appropriate here.
