Hi list, I've been following a discussion on a new way of defining getters and setters on python-dev and just can't understand what the purpose is. Everybody agreed on the dev list that this is a good idea so I guess it must be right :)
The whole thing started with this post of Guido: http://mail.python.org/pipermail/python-dev/2007-October/075057.html which then continued into November. Basically, the idea is that using the new way a setter can be added to property that was read-only before. But if I have this already, class C: @property def attr( self ): return self._attr what prevents me using the following for adding a setter for attr: class C: def attr( self ): return self._attr def set_attr( self, value ): self._attr = value attr = property( attr, set_attr ) In other words all I needed to do is delete @property, write the setter method and add attr = property( attr, set_attr ). What does the new way improve on this? -- http://mail.python.org/mailman/listinfo/python-list
