If you do not have PyQT5 installed, you should install it first. In a terminal you can type:

sudo apt-get install python3-pyqt5

If you are on a Windows or Mac computer, you can download PyQT5 from: https://www.riverbankcomputing.com/software/pyqt/download5

PyQt5 window

You can create a PyQT5 window using the code below:

import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtGui import QIcon
class App(QWidget):
def __init__(self):
        super().__init__()
        self.title = 'PyQt5 simple window - pythonspot.com'
        self.left = 10
        self.top = 10
        self.width = 640
        self.height = 480
        self.initUI()
        
    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.show()
    
if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

We set the window size using the setGeometry(left,top,width,height) method. The window title is set using setWindowTitle(title). Finally show() is called to display the window.

Run with:

python3 window.py

The output should look similar to the screenshot above (depending on your operating system).
