[Python] What is the common way for incrementing/decrementing one or more attributes that...

So I have been experimenting with draggerContext, a simple command, that can be used to for example increment or decrement a value repeatedly as the user drags left or right. I really like to this kind of utility and so I want to build a few of them, all in the same vain; increment or decrement one or more attribute values.

I am now trying to wrap my head head around a common generic, and even, efficient ways of doing implementing section, that is the "get the attribute value and then set attribute value".

Speaking from a point of view of someone that has little experience with Maya programming conventions, are getAttr and setAttr the way forward here? Just from pure speculation, I am thinking that since I am dealing with high a fidelity control (mouse movements) there could be slow downs, since I would need to getAttr, then setArr for every potential attribute.
