The single leading underscore is nothing to do with visibility; it's a courteous request that external referents not touch something. In a "consenting adults" model, that's usually sufficient. For the most part, in fact, you don't need @property at all. Just make an object's members public and save yourself the trouble! Unlike the recommendation in C++ and Java, Python doesn't ask you to hide things and write code to make them available. Instead of starting with getters and setters, just start with a flat property, and move to getters/setters only when you find you need them. The example you posted is adding nothing to the work flow, but it's a good structure that you can tinker with. For instance, if you need to log all changes for debugging purposes, @property will make that easy. But for the bulk of attributes, it's complete overkill.
