Я получаю ошибку импорта при попытке импортировать этот модуль.

                print(question)



                input(" > ")

                print(f"ANSWER: {answer}")

except:
    print("Bye")

Ошибка, которую я получаю, такова :
ImportError: не удается импортировать имя 'ascii_letters'

Что я уже пробовал:

Я попытался написать его как import utllib.urlopen, но он показал синтаксическую ошибку.
