NB : properties are for computed attributes, not to "avoid giving direct 
acces to (an) attribute". If what you need is really a public attribute, 
  then use a plain attribute - knowing you'll be able to switch to a 
property if and when the need arises.

I just can second Gabriel on this: as long as it's not computation 
intensive, I use a read-only attribute (ie: fset and fdel raising 
AttributeError('attribute XXX is read-only')).
