Just an Idea to do it

I have 10 objects and want to do something if a collision happens between any of them and Box1. Box 1 can collide with other objects, but I do not want to do anything with that.
I have done that by writing if statement for all of them, but this way is really hard to accommodate
I have to write this
 if Box in viz.phys.intersectNode(Obj1) :
if Box in viz.phys.intersectNode(Obj10):
Anybody has an idea?

You can register a callback function for collision events. If each of these 10 objects has collide notify enabled:
<node3D>.enable( viz.COLLIDE_NOTIFY )
then whenever a collision happens with one of those objects the function will get called. Then you can check to see if the second node passed with the event object is the box:
#Called when two objects collide in the physics simulator
def onCollide(e):
    #Did object collide with box?
    if e.obj2 == box1:
        #Do something
viz.callback( viz.COLLIDE_BEGIN_EVENT, onCollide )
