Как проверить все lineEdit на пустоту

Автор вопроса: Kkrski

Я хочу проверить все lineEdit's на пустоту. Для одного lineEdit у меня получается и выводит 'Okey', но я хочу сделать для всех.

 def process(self):
    num1 = (ui.lineEdit.text())
    num2 = (ui.lineEdit_2.text())
    num3 = (ui.lineEdit_3.text())
    num4 = (ui.lineEdit_4.text())
    num5 = (ui.lineEdit_5.text())
    num6 = (ui.lineEdit_6.text())
    if len(num1) > 0:
        print('okey')
        return
    print('error')

Я пытался сделать так в виде списка, но не работает:

 def process(self):
    num1 = (ui.lineEdit.text())
    num2 = (ui.lineEdit_2.text())
    num3 = (ui.lineEdit_3.text())
    num4 = (ui.lineEdit_4.text())
    num5 = (ui.lineEdit_5.text())
    num6 = (ui.lineEdit_6.text())

    list = [num1, num2, num3, num4, num5, num6]

    if len(list) > 0:
        print('okey')
        return
    print('error')

UPD - Не понимаю почему не работает...

Update

У меня не получилось под свое сделать, ваше все работает и хорошо, я обновил пост

НИКОГДА НЕ ИЗМЕНЯЙТЕ код, сгенерированный Qt Designer, НИКОГДА.
Создайте другой класс, который наследуется от соответствующего виджета, и используйте созданный класс для его заполнения.
