Catching signal from QlineEdit() PyQt5?

Good afternoon.
Deploy GUI Python application with PyQt5 GUI module.
Compiled the application in Qt Design.
After that, two files main.py and mydes.py are displayed.
I can not catch the value received by the method.
text = self.EnterText.text()
Print(text) I
will provide the code on repl with the ability to edit and further down the text.
MAIN.py

from PyQt5 import QtWidgets
from mydes import Ui_Form  # импорт нашего сгенерированного файла
from PyQt5.QtCore import pyqtSignal, QObject
import sys
 
 
class mywindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(mywindow, self).__init__()
        super().__init__()
        self.ui = Ui_Form()
        self.ui.setupUi(self)

        self.ui.BUTTONpush.clicked.connect(self.btnClicked)
        text = self.ui.EnterText.text()

    def btnClicked(self):
        #self.ui.label.setText("Вы нажали на кнопку!")
        # Если не использовать, то часть текста исчезнет.
        #self.ui.label.adjustSize()
        print('Нажали на кнопку' )
        print(text, 'введеный текс')
    
    def mostrarFuncion(self):
        minombre = self.EnterText.text()
        micontrasena = self.contrasena.text()
        print("Nombre: " +minombre + " Contrasena: ")
        self.setWindowTitle("Nombre: " +minombre + " Contrasena:")

app = QtWidgets.QApplication([])
application = mywindow()
application.show()
 
sys.exit(app.exec())

everything works, only you need to correct text to self.text
and you have an ambush in mydes.py

self.BUTTONpush.clicked.connect(self.EnterText.clear)

perhaps because of this, the text is reset to zero and an empty value is passed
