Python извлекает и добавляет данные во фрейм данных

Question

Я просмотрел веб-сайт для своих исследований, но не смог найти правильный способ извлечь его во фрейм данных. Я считаю, что моя проблема связана с объектами списка, которые находятся между строками 36 и 38.

Строка печати работает очень хорошо, и я вижу окончательную версию фрейма данных в консоли Python.

Решение может быть очень простым, но я не мог понять это. Заранее спасибо за помощь.
