Hi All,

I see in Python 3, some ImportErrors have grown a 'notfound' attribute. What's the significance of this attribute and where/how is it added? The only way I can seem to create this attribute is: ex = ImportError ex.notfound = True It's something importlib does to get fromlists to behave the same way they did in the C implementation. It is set here: http://hg.python.org/cpython/file/3.3/Lib/importlib/bootstrap.py

OK.

Have any other exceptions grown new attributes in Python 3?

cheers,

Chris
