You need a try/except, or some other form of validation here, otherwise:

>>> b.get_age()
'Six'

I can't help you with that question, since I'm still (!) wrapping my
head around objects and haven't really gotten around to looking at
data validation and when/how you should do it. I would probably use
try/except for the __init__ and the setter.
