The normal Pythonic way is probably as follows:

def setPos(position):
   """
   Set Position. 

   The 'position' argument should be one of
      * a tuple of coordinates (x,y)
      * a instance of class Pos
      * a instance of class Object
   """

   if type(positions) is types.TupleType or type(positions) is types.ListType: 
       x,y = positions
       ...   
   else if: 
      ... identify object type and process
