Lets say you created an float variable

float $testvar;

then say you create a polygon cube in your scene.

polyCube;
//Result: pCube1

then you wanted to query the value of pCube1's translateY and assign it to the $testvar float attribute.

how do you query the value of a transform's attribute.
like pCube1.ty?

I have been in situations where i had to query the value of other things like UI elements but UI elements like windows already have a flag for querying.

Ex. maybe you ran into one of these before

if((`window -q -exists testwindow`)==true) deleteUI testwindow;

well is there some kind of query flag for transforms also?
