[0.0, 0.0, 0.0] for every object.getPosition()

Please use the [code][/code] tags when posting sample code on the forum. This will preserve indentation which is necessary for running Python code.

In your code, you are incorrectly using the valid attribute of the node object. It is a function, so you need to call it:

if object.valid():
    print object.getPosition()
