Steven,
thanks for a nice explanation.
I am trying to experiment a little bit with new-style class and I am
confused why following example always returns 0 (zero). I was
expecting will return values from 0 to 9 and finaly
an Exception.
class GenExample(object):

Hi all,
I am trying to understand new-style classes in Python and I have found
your postings here.
Gabriel, if I understand it properly, it is necessary to define get/
set/del/doc methods for each attribute for which I want to set the
"property" data descriptor (which triggers get/set/del/doc fun

I didn't actually answer your question, my apologies!
The reason you're failing is due to your use of the __setattr__ call.
Remember, when you override __setattr__, you need to handle *all* of the
logic behind setting object attributes. You're only attempting to do so
when handling the 'name' pro
Thanks you Gabriel and Timm for your thoughtful responses. I am very
appreciative.
I had heard about the properties function, but wanted to understand
the old syntax first before I tried that. Thanks to your responses, I
was able to see what the problem was.
Here is a solution I came up with:
A couple items of note:

This should be "class Person(object)" to take advantage of some
of the features that new-style classes offer...particularly in
this case.

Perhaps you'd be better off using a standard property? Within your Person
class, you can define a property 'name' to handle what you're trying to do:

Hi Python Community:
Despite my new-ness to Python I have alreadhy been able to do some (I
think) amazing things. It is a truly elegant and smart language.
Yet, I can not seem to get a handle on something simple.
I would like to make a class which has private varaiables fName and
lName. It sh
