Very rarely, and mainly when you need to access a number of attributes 
some of which are pure data and others are derived via a method. You can 
make the methods look like data by making them properties.

In 18 years of using python I've used @property about 3 or 4 times in 
real projects.

It is used a lot in Delphi (Object Pascal) and some similar
languages but it's not often needed in Python.
