Jika objek memiliki Python properti
Use hasattr()
hasattr(object, name)
#The arguments are an object and a string.
#The result is True if the string is the name of one of the
#object’s attributes, False if not.
#(This is implemented by calling getattr(object, name) and
#seeing whether it raises an AttributeError or not.)
