It was definitely not clear to me. Judging from his latest reply it 
doesn't seem to be clear to Alan either.

So if an attribute is initialized in a different method would you still 
put a dummy initializer in __init__()?

I honestly don't see how you can conclude that. My post was the first 
one that mentioned __init__() at all. You have been talking about the 
class definition which could mean "anywhere in the scope of the class 
statement" or, as I thought you might mean, "anywhere in the scope of 
the class statement that is not in a method". I personally would never 
interpret "class definition" to mean the __init__() method.

I really am trying to understand what you are asking, it is not clear to 
me at all.
