The __iter__ method should return an iterator.

You can either use the iter function to create an iterator from the tuple:

def __iter__(self):
    return iter((self.name, self.value, self.image))

or use the yield from statement to achieve the same:

def __iter__(self):
    yield from (self.name, self.value, self.image)
