I have a similar example with Qt4 on this blog.
The main reason for this tutorial comes from the idea of simplicity and reuse the source code from PyQt4 and PyQt5.
I do not know if there are significant changes to the Qt5 base IU. However, it is good to check on the official pages. Let's look at the example with comments specific to source code lines:

import sys
from PyQt5.QtWidgets import QMainWindow, QAction, qApp, QApplication, QDesktopWidget
from PyQt5.QtGui import QIcon
class Example(QMainWindow):
#init the example class to draw the window application
def __init__(self):
super().__init__()
self.initUI()
#create the def center to select the center of the screen
def center(self):
# geometry of the main window
qr = self.frameGeometry()
# center point of screen
cp = QDesktopWidget().availableGeometry().center()
# move rectangle's center point to screen's center point
qr.moveCenter(cp)
# top left of rectangle becomes top left of window centering it
self.move(qr.topLeft())
#create the init UI to draw the application
def initUI(self):
#create the action for the exit application with shortcut and icon
#you can add new action for File menu and any actions you need
exitAct = QAction(QIcon('exit.png'), '&Exit', self)
exitAct.setShortcut('Ctrl+Q')
exitAct.setStatusTip('Exit application')
exitAct.triggered.connect(qApp.quit)
#create the status bar for menu
self.statusBar()
#create the menu with the text File , add the exit action
#you can add many items on menu with actions for each item
menubar = self.menuBar()
fileMenu = menubar.addMenu('&File')
fileMenu.addAction(exitAct)
#resize the window application
self.resize(640, 480)
#draw on center of the screen
self.center()
#add title on windows application
self.setWindowTitle('Simple menu')
#show the application
self.show()
#close the UI class
if __name__ == '__main__':
#create the application
app = QApplication(sys.argv)
#use the UI with new class
ex = Example()
#run the UI
sys.exit(app.exec_())
