Привет, я просто тестирую этот пример проекта здесь и получаю эту странную ошибку и могу понять это ? //

capitals_questions = 'Capitals Questions'
math_questions = 'Math Questions'

questions = [animals_questions, capitals_questions, math_questions]

                         ("Another capitals question", True),
                         ("Last capitals question", False)],

        math_questions: [("20 is log 100 for base 1o", False),

choice = get_quiz_choice()
quiz_name = questions[choice - 1]
print ("\nYou chose the ()\n").format(quiz_name)
quiz_questions = quiz[quiz_name]
for q in (quiz_questions):
    print ("Your answer is: {}\n").format(str(get_answer(q[0], q[1])))

Что я уже пробовал:

мне фиксированную сумму на ошибки поставил им получать ошибки на печать (при использовании"Q: {}").формат(вопрос)
