Build a fully functional calculator application while learning the fundamentals of desktop GUI development with PyQt5 and Python. In this project-based course, you will progress from setting up your development environment to designing an interactive graphical user interface and implementing the logic that powers a working calculator. You will begin by configuring Python, PyCharm, and the required PyQt5 packages before exploring essential GUI components such as QLabel, QPushButton, and QRect-based layouts. As you build the application, you will implement calculation logic using object-oriented programming principles and PyQt's signal-slot mechanism to process user input and perform arithmetic operations. Designed for learners with Python knowledge who want practical experience in desktop application development, this course emphasizes learning by building a complete, real-world project. Rather than focusing on isolated concepts, each lesson contributes directly to creating a functional calculator with a clean interface and interactive features. By the end of the course, you will be able to design a PyQt GUI from scratch, organize interface components, implement calculator logic, and test a complete desktop application. If you want to strengthen your Python GUI development skills through hands-on practice, this course provides a structured path from setup to a finished PyQt calculator project.

I was disappointed that the calculator project did not employ QT Designer to layout the calculator GUI. Perhaps I started with the wrong premise, but my primary reason for learning PyQt was to layout my project's GUI using a GUI layout tool. This CALC project was not much different than creating a calculator using Tkinter, but using the Qt widgets instead of Tk. It would also have been helpful to have a picture of the final CALC GUI image on the screen during all of the button layout videos. The instructor could point to buttons in the image immediately before changing the widget positions and width in the code. This would give the viewer a better mental picture of why the positions and widths are being changed to the new values. It would also have been nice to see at least part of the final CALC test after the CALC widget layout code had been entered, and before starting the operational function code. This would provide the viewer with a sense of what the operational code needs to do, right before beginning to create the operational code itself.
