Project on PyQt - Creating a Calculator

This project-based course guides learners through the design and development of a fully functional calculator application using PyQt5 and Python. Starting from environment setup to interface layout and backend logic integration, learners will gain hands-on experience building real-world GUI applications. The course begins by introducing key PyQt concepts, setting up a Python development environment in PyCharm, and installing essential packages. Through structured lessons, learners will design the graphical interface using widgets like QLabel, QPushButton, and geometric layout tools such as QRect. They will then implement core logic using object-oriented programming principles and PyQt’s signal-slot mechanism. By the end of the course, learners will be able to construct a GUI from scratch, apply logical operations based on user input, and demonstrate a complete PyQt application with interactive features and clean visual structure. This course is ideal for developers seeking to apply their Python skills in desktop application development using PyQt.
