help needed running a simple function in pyqt5

[diodes]

Ok, I did some reading and I made the UI. However, I am still clueless on how to get the button to take variables x and y from my input fields and then display them in a text edit box. here is the best I could come up with.

import random
from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):     #my main window
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(358, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget) 
        self.pushButton.setGeometry(QtCore.QRect(120, 120, 89, 25))
        self.pushButton.setObjectName("pushButton")
        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(40, 50, 51, 25))
        self.lineEdit.setMaxLength(100)
        self.lineEdit.setObjectName("lineEdit")  # I need this to take my x integer
        self.lineEdit_2 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_2.setGeometry(QtCore.QRect(210, 50, 51, 25))
        self.lineEdit_2.setMaxLength(200)
        self.lineEdit_2.setObjectName("lineEdit_2")   # I need this to take my y integer
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(30, 20, 151, 17))
        self.label.setObjectName("label")
        self.label_2 = QtWidgets.QLabel(self.centralwidget)
        self.label_2.setGeometry(QtCore.QRect(210, 20, 131, 17))
        self.label_2.setObjectName("label_2")
        self.label_3 = QtWidgets.QLabel(self.centralwidget)
        self.label_3.setGeometry(QtCore.QRect(90, 160, 161, 17))
        self.label_3.setObjectName("label_3")
        self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
        self.textEdit.setGeometry(QtCore.QRect(70, 190, 201, 321))
        self.textEdit.setObjectName("textEdit")   #the place I want my results to display
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 358, 22))
        self.menubar.setObjectName("menubar")
        self.menuLotto_Picker = QtWidgets.QMenu(self.menubar)
        self.menuLotto_Picker.setObjectName("menuLotto_Picker")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.action_Exit = QtWidgets.QAction(MainWindow)
        self.action_Exit.setObjectName("action_Exit")
        self.actiongenerate = QtWidgets.QAction(MainWindow)
        self.actiongenerate.setObjectName("actiongenerate")  #with this action i want to generate the random numbers by pressing this button.
        self.menuLotto_Picker.addAction(self.action_Exit)
        self.menubar.addAction(self.menuLotto_Picker.menuAction())

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

    def retranslateUi(self, MainWindow):  #the titles of all my labels
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "Generate"))
        self.label.setText(_translate("MainWindow", "How Many Numbers"))
        self.label_2.setText(_translate("MainWindow", "How Many Spots"))
        self.label_3.setText(_translate("MainWindow", "Your random Numbers"))
        self.menuLotto_Picker.setTitle(_translate("MainWindow", "Lotto Picker"))
        self.action_Exit.setText(_translate("MainWindow", "&Exit"))
        self.actiongenerate.setText(_translate("MainWindow", "generate"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

if anyone can help me accomplish my goals I would be very thankful.
