How pass data from second window to main?

I have a python app that change mac address with pyqt5 GUI. I have two python files. The main python file (mainWindow.py) that run main program then I press button to open the second window from second python file secondWindow.py. In second python file opens a window entry then I have to put letters and numbers like then I have to pass data in the first main app label window.
Can anyone help me to solve that?
I tried to reduce code.

One solution would be to assign the MainWindow as the parent of the SecondWindow. Then to get the label text all the SecondWindow has to do is self.parent.label.setText('something'). See the minor adjustments I made below.
mainWindow.py
class Ui_MainWindow(object):
def specificWindow(self):
self.window = QtWidgets.QDialog()
self.ui = Ui_macSpecific()
self.ui.setupUi(self.window, self) # <--- assign MainWindow as parent to second window
self.window.show()
secondWindow.py
import macspoof_bash
class Ui_macSpecific(object):
def setupUi(self, macSpecific, master):
self.master = master
self.window = macSpecific
macSpecific.setObjectName("macSpecific")
macSpecific.resize(301, 140)
...
...
self.pushButton = QtWidgets.QPushButton(macSpecific, clicked = lambda: self.submit())
def submit(self):
print("submit")
text = self.lineEdit.text()
self.master.label_3.setText(text)
self.window.close()
config['ethernet']['wired_mac_address'] = text
with open("macspoof.ini", "w") as inifile:
config.write(inifile)

How to pass parameters bw two windows in pyqt5?

I am working on a password manager gui app. Using Qtdesigner I created a main window where I asked for username and password from user. and a dialog window where display the user their username and passwords for different apps and websites. I also called that dialog window from my main window so that when user press login button then if their login credential is correct , the dialog window will appear.
Now what I want is that when dialog window appears,after clicking push button it should show all data of the user which is stored in a table with that username(like if username is alex then a table with name alex is there in db with username and passwords of different apps/websites).
Hope my question is understandable enough to be answered. I can further clarify if anyone interested to answer.

I use the QStackedWidget to switch between pages.
app = QApplication(sys.argv)
stackedwidget = QtWidgets.QStackedWidget()
page1 = PageOneClass()
page2 = PageTwoClass()
stackedwidget.addWidget(page1)
stackedwidget.addWidget(page2)
stackedwidget.show()
app.exec_()
This will let you switch between pages without running another file. Now to get values from one page to another, use inheritance.

#we are passing the mainwindow instance to the dialog window instance, this will let us use all the methods and attributes of the mainwindow.

PyQt5 identical push buttons, one works one doesn't

I tried writing some codes using pyqt5 and have two main windows and push buttons, for both cases I have done same but one works on clicked.connect and one doesn't. Pasting code for the button which doesn't work. I call this window after closing first one
I tried creating module outside of class and that worked but then struggled with referencing to lineEdit objects

I want Checkbutton on click event to work, please help

For Ui_Premix, used self.Checkbutton.clicked.connect(Ui_PREMIX.on_click) instead of
self.on_click even though on_click event was inside class, it works now
