done a setattr on a property gives a very unhelpful error message AttributeError: can't set attribute it neither indicates the name of the attribute that failed or the cause. an error such as "can't set property attribute: the_attr_name" would be far more helpful. |

Usually, all the necessary information is present in the previous line of the traceback:
>>> a.volume = 10
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
a.volume = 10
AttributeError: can't set attribute
I don't seem to recall anyone else having problems with this error message.

The trackback is not helpful if the attribute name is in a variable. It also doesn't explain why the error occurred. While I would not rate this as a high priority, I don't see an argument for having uninformative error messages.
