Project on PyQt - Creating a Calculator

About this course

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.
