Как объединить списки или, альтернативно, создать список списков

У меня есть игра на память, в которой вам нужно найти пары плиток с одинаковыми изображениями. Я хочу модифицировать игру так, чтобы вам приходилось находить пары плитки с изображением и плитки с соответствующим текстом. Например, найдите плитку с изображением кота и плитку с текстом «кошка».

Чтобы понять проблему, вот код, который я считаю наиболее подходящим, показывающий, как я сейчас использую список изображений для создания пар плиток:

class Tile(object):
    def __init__(self, canvas, x, y, image, cardback):
        self.image = image
        more stuff...

class MemGame(tk.Frame):
    def __init__(self, master):
        super(MemGame, self).__init__(master)

        self.images = [
            photoDog,
            more images...
        ]

        selected = []
        for i in range(10):
            randomInd = randint(0, len(self.images) - 1)
            animalImg = self.images[randomInd]
            selected.append(animalImg)
            selected.append(animalImg)
            del self.images[randomInd]
        shuffle(selected)
        self.flippedTiles = []
        NUM_COLS = 5
        NUM_ROWS = 4

        for x in range(0, NUM_COLS):
            for y in range(0, NUM_ROWS):
                self.tiles.append(Tile(self.canvas, x * 108 + 10, y * 108 + 40, selected.pop(), photoCardback))

Я не уверен, должен ли я создать еще один список текстов или изменить список изображений на список списков с изображением и текстом.

Если нужно, вот полный код:

        # on top of each other, then the one we want visible
        # will be raised above the others
        container = tk.Frame(self)
        container.pack(side = "top", fill = "both", expand=True)
        container.grid_rowconfigure(0, weight=1)
