Answer 1

other gui.py:

import sys
from PyQt5 import QtGui
from PyQt5.QtWidgets import QMainWindow, QApplication, QStatusBar


class Window(QMainWindow):
   def __init__(self):
       super().__init__()

       self.InitUI()

   def InitUI(self):

       self.statusBar().showMessage("This is a simple Status bar")

       self.setWindowTitle('GUI')
       self.setGeometry(200, 200, 600, 500)

first gui doesn't need to be chnged

Just replace your code by this:

from notepad import notepad
self._new_window = notepad()
self._new_window.showMaximized()
self.hide()
