Sorry if this is late info but, the Maya hasAttr is meant to check for the existence of attributes on an object. But these are not functions as everything in Maya command API are string references and you use function calls only to perform certain operations on string references Python has a similar hasattr which tells you if a python object has a certain member attribute
In your case, neither of these applied, as what you were after was just to try and call the PyMel getShape and handle the specific AttributeError Hope that was clear enough?
