I'm creating a program with PyQt5 and have made to .py files for two windows. One is a logIn window and the other is the mainWindow. To open the program a separate program, main.py, will call a subroutine in the logInWindow.py to open that window up. There is a button there that when clicked is supposed to close the logIn window and open up the mainWindow.py by calling it. The main window opens up fine but the logIn window doesn't close. I need it so that the logIn window closes once the mainWindow is open. It doesn't matter if it does it before, during or after the mainWindow is open but as long as it does. I also need to be able to pass a value from the logInWindow to the mainWindow because of other parts of the program. I've made a simplified version of the code below.

I tried using things such as QtWidgets.QDialog().close() (which were recognised by the code) but didn't actually do anything. The only thing that closed it was sys.exit() but that shut the whole thing down before the line code to open the mainWindow.

#main.py
import logInWindow

var1 = input("Start: ")
if var1 == 'y':
 logInWindow.openUp()

#logInWindow.py
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import mainWindow

class Ui_Dialog(object):
 def setupUi(self, Dialog):
 Dialog.setObjectName("Dialog")
 Dialog.resize(400, 135)
 self.pushButton = QtWidgets.QPushButton(Dialog)
 self.pushButton.setGeometry(QtCore.QRect(110, 50, 161, 32))
 self.pushButton.setBaseSize(QtCore.QSize(161, 32))
 self.pushButton.setObjectName("pushButton")
 self.pushButton.clicked.connect(self.buttonClick)

 self.retranslateUi(Dialog)
 QtCore.QMetaObject.connectSlotsByName(Dialog)

 def buttonClick(self):
 #code to close logInWindow here
 needsToBePassed = 'This is the main window.'
 mainWindow.openUp2(needsToBePassed)

 def retranslateUi(self, Dialog):
 _translate = QtCore.QCoreApplication.translate
 Dialog.setWindowTitle(_translate("Dialog", "logInWindow"))
 self.pushButton.setText(_translate("Dialog", "open mainWindow"))

def openUp():
 import sys
 app = QtWidgets.QApplication(sys.argv)
 Dialog = QtWidgets.QDialog()
 ui = Ui_Dialog()
 ui.setupUi(Dialog)
 Dialog.show()
 sys.exit(app.exec_())

#mainWindow.py
from PyQt5 import QtCore, QtGui, QtWidgets
import sys

def openUp2(passed):
 class Ui_Dialog(object):
 def setupUi(self, Dialog):
 Dialog.setObjectName("Dialog")
 Dialog.resize(400, 300)
 self.label = QtWidgets.QLabel(Dialog)
 self.label.setGeometry(QtCore.QRect(110, 130, 151, 16))
 self.label.setObjectName("label")

 self.retranslateUi(Dialog)
 QtCore.QMetaObject.connectSlotsByName(Dialog)

 def retranslateUi(self, Dialog):
 _translate = QtCore.QCoreApplication.translate
 Dialog.setWindowTitle(_translate("Dialog", "mainWindow"))
 self.label.setText(_translate("Dialog", passed))

 Dialog = QtWidgets.QDialog()
 ui = Ui_Dialog()
 ui.setupUi(Dialog)
 Dialog.exec_()

If anyone could help me out that'd be great! Also if it's a few lines of code instead of changing how the code works, that'd be better but either would do.
