How to save the written text in QLineEdit when exiting the application?

Question

PyQt

I made a macro that prints the text written in QLineEdit, but when you restart the application, you have to enter the text again, which is not convenient, and I can’t figure out how to make the text stay in QLineEdit when you restart
. Here is a simplified version of my code

from PyQt5.QtCore import QTimer
from PyQt5.QtWidgets import QApplication, QMainWindow, QMessageBox
import time
import keyboard
import pyautogui

import sys
from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_ChatSpamer(object):
    def __init__(self):
        super(Ui_ChatSpamer, self).__init__()

    def setupUi(self, ChatSpamer):
        ChatSpamer.setObjectName("ChatSpamer")
        ChatSpamer.setEnabled(True)
        ChatSpamer.resize(500, 430)
        ChatSpamer.setMinimumSize(QtCore.QSize(500, 430))
        ChatSpamer.setMaximumSize(QtCore.QSize(500, 430))
        font = QtGui.QFont()
        font.setBold(False)
        font.setWeight(50)
        ChatSpamer.setFont(font)
        ChatSpamer.setStyleSheet("")

        self.centralwidget = QtWidgets.QWidget(ChatSpamer)
        self.centralwidget.setObjectName("centralwidget")

        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(30, 70, 291, 20))
        self.lineEdit.setTabletTracking(False)
        self.lineEdit.setObjectName("lineEdit")

    def spammer(self):
        if keyboard.is_pressed('f7'):

            keyboard.send('t')
            time.sleep(0.6)
            keyboard.write(self.lineEdit.text(), delay=0.02)
            time.sleep(0.6)
            keyboard.send('Enter')
            time.sleep(6)

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    ChatSpamer = QtWidgets.QMainWindow()
    ui = Ui_ChatSpamer()
    ui.setupUi(ChatSpamer)
    ChatSpamer.show()

    run_inf = QTimer()
    run_inf.setInterval(0)
    run_inf.timeout.connect(ui.spammer)
    run_inf.start()

    sys.exit(app.exec_())

Answer 1

https://docs.python.org/3/library/configparser.html
and if the text does not change, you can immediately fill in the form

Answer 2

Ultra-Bad Coder Not working, and most likely there is an error due to the last line of ui.save () as it is highlighted in yellow
