Build a fully functional calculator while developing practical desktop GUI skills with PyQt5 and Python. In this project-based course, you’ll move step by step from configuring Python, PyCharm, and the required PyQt5 packages to creating and testing a complete calculator application.

You’ll explore essential GUI components, including QLabel, QPushButton, and QRect-based layouts, as you design and organize an interactive calculator interface. You’ll then apply object-oriented programming and PyQt’s signal-slot mechanism to process user input, implement calculation logic, and perform basic arithmetic operations. This course is designed for learners with Python knowledge who want hands-on experience in desktop application development. By the end, you’ll be able to design a PyQt GUI from scratch, arrange interface components, build functional buttons, implement and evaluate arithmetic logic, and test the finished application. What makes this course unique is its focused, build-as-you-learn approach: every lesson contributes directly to one working PyQt calculator rather than presenting GUI concepts in isolation. Enroll to strengthen your Python GUI development skills and gain practical experience turning interface designs and program logic into a functional desktop application.
