[Python-Dev] Re: changing AttributeError to TypeError

[Guido van Rossum]

I just noticed another place that swaps a TypeError for an
AttributeError.

In 2.1 and before, assigning to an attribute of an object that doesn't
support attribute assignment (like a list) raises TypeError.
Under the new scheme, this will raise AttributeError.

(On the other hand, assigning to a read-only attribute of an object
that *does* support attribute assignment raises TypeError in the old
and new scheme.)
