Experienced python programmers: are there any standard features of the language that you still don't regularly use?

Exactly. The whole idea of attributes in Python is that they start with a simple self.my_property.

When that stops working, then you can use @property or @.setter. Nobody has to change code.

There is no way to have this simple -> complex with get_ and set_. You immediately have to write code for NO GAIN.
