Increased size of attribute with function and random.choice() began having an error I've never seen before.

In the Final Product lesson https://teamtreehouse.com/library/final-product

I added the following code to create the option to select difficulty:

def select_difficulty(self):
    difficulty = input('How good is your memory? Choose one of the following: \n pot smoker\n memory pimp\nEnter memory level:  ')
    pimp_options = ['Kay', 'Way', 'Ray', 'Hay', 'Bay', 'Way', 'Tay', 'Que']
    pimp_columns = ['E', 'F', 'G', 'H']
    if difficulty == 'memory pimp':
        self.grid = 8
        for i in pimp_columns:
            self.column_options.append(i)
        for i in pimp_options:
            self.card_options.append(i)
    if difficulty == 'pot smoker':
        pass

I got the following error and I dont know what it means: File "/home/treehouse/workspace/game.py", line 111, in <module>
game.run_game()
File "/home/treehouse/workspace/game.py", line 89, in run_game
self.set_cards()
File "/home/treehouse/workspace/game.py", line 28, in set_cards
random_location = random.choice(list(available_locations))
File "/usr/local/lib/python3.9/random.py", line 346, in choice
return seq[self._randbelow(len(seq))]
IndexError: list index out of range

Any help would be greatly appreciated <3
