Как переходить между виджетами pyqt5. Передача информации из первого скрытого виджета в другой показуемый
Помогите реализовать. Есть главное окно, на котором студент должен будет вбивать ФИО, группу и номер по списку.
Как мне передавать номер по списку в следующий виджет, после нажатия на кнопку "Далее"(зеленая кнопка)? и как возвращаться обратно к первому виджету при нажатии кнопки "Назад"(зеленая кнопка).
И вообще правильно ли я делаю, что скрываю центральный виджет, может есть какая-то более корректная альтернатива?

Update
хотел бы узнать можно ли как-нибудь открывать второй виджет не в отдельном окне, как у вас, а в этом же окне программы (просто скрывая основной и показывая другой, и наоборот)?
Все можно, но другой вопрос насколько это нужно. Обратите внимание, что в этом примере используются приведенные ваши модули first_try.py и second_try.py.
