In looking at tutorials for Qt Designer I see instructions to use pip install pyqt5-tools but it appears that there are only wheels available for Win32.

PyQt Hello World Example
A simple window
Code Interpretation
QtWidgets component module is imported here.
Each PyQt5 application must create an application object. sys.argv is a list of command line arguments. python can be run in the shell. this parameter provides control over the script.
The QWidget control is a basic UI control that provides the basic application constructor. By default, the constructor is without a parent, and a constructor without a parent is called a window.
The resize() method can change the size of the control, which means that the window is 250px wide and 150px high.

move() is a way to modify the position of the control. It places the control to the (300, 300) position of the screen coordinates. Note: The origin of the screen coordinate system is the top left corner of the screen.
We added a title to this window, which is displayed in the title bar
Finally, we are in the main loop of the application and the event processor starts working at this time. The main loop receives events from the window and passes them in to the dispatch to the application control. The main loop ends when the exit() method is called or when the main control is destroyed directly. sys.exit() method ensures that the main loop is safely exited. The external environment can tell the master how to end.
