Не работает class в PyQt5

Автор вопроса: Yraron

У меня возникла проблема. В приведённом ниже коде не работает класс OK_Window().

Пожалуйста объясните почему не работает, как это решить и что мне выучить.

Мой код:

import cryption as cry
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QLabel, QVBoxLayout, QWidget
from PyQt5 import QtCore, QtGui, QtWidgets
print('1')
class Ui_MainWindow(QMainWindow):
    def crypte(self):
        self.edit_1 = self.textEdit.text ()
        self.edit_2 = self.textEdit_2.text ()
        self.edit_3 = self.textEdit_3.text ()
        print('4.1')
        print(self.edit_1, self.edit_2, self.edit_3, '1')
        self.qwerty = cry.crypt(self.edit_1, self.edit_2, self.edit_3)
        global qwerty 
        qwerty = self.qwerty
        print(qwerty)
        print('4.2')
        w2.show()
        print('4.3')

    def setupUi(self, MainWindow):

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

Update:

с вашим кодом у меня перестали работать QLineEdit введения языка и введения спец-кода, вы не знаете почему?
Я просто не могу ввести туда текст, курсор остаётся обычным,
а не в форме I

Sorry, но код ваш. Я же вам отметил как # ??? и строки self.label... - что это? Вы этим self.label накрываете почти все в вашем окне, потому что self.label.setGeometry(QtCore.QRect(0, 0, 470, 150))

Научитесь использовать менеджеры компоновки (Layout Management) !!!
