Отображение данных парсера в PyQt
Решил визуализировать парсинг фильмов с сайта imdb.com.
Нужно чтобы при нажатии на кнопку pushButton_title Отображался мой парсер.
Пробовал, но не получалось, решил оставить как есть, в надежде что тут помогут.
Прилагаю код на pyqt:
import sys

Sorry, мне не приглянулась ваша форма, но то что вы задумали может выглядеть примерно так:

i += 1
