[Closed] how to this ?????

I am trying ot write a script for unhiding and unfreezing all the objects including layers
my code is like this
It should basically select every object including helpers, shapes, geometry …

Here I am trying on simple boxes

 for o in selection where not(o.layer.on) and (o.layer.unfreeze )  do o.layer.on = true
 (
     select $box*

unhide selection dolayer:true
unfreeze selection dolayer:true
)

This is working fine but I have to run the same code for 3 times to get what I desire
anything wrong with this code???
