I want to sum up some ideas in the thread:

1) setters and getters are not mandatory.

2) The usual way in Python is the direct access 

> [=] ... b.width   # is get
> b.width =         # is set
> del b.width       # is del

3) If when setting some attribute there is necesary to have side
   effects, it can be achive defining __setattr__ and doing the right
   thing depend on the attribute. (It is possible to raise an
   exception when the attribute is not in a list/dictionary of usable
   attributes, to prevent typos and such kind of errors)

4) __getattr__ can be defined to deal with undefined attributes. For
   example it can handle in different way the attributes in a list of
   permited attributes (see point 3)

5) attributes that are computed in the fly, can be get like normal
   attributes using "property" (property is new in 2.3 or 2.2?)

6) attributes and methods that are no part of the user interface are
   named with and _ in the front. (This is a convention)

Are those ideas correct? We can continue with the discussion!!
