Project on PyQt - Creating a Calculator

Overview

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.

Syllabus

Building a Functional PyQt Calculator

This module introduces learners to the fundamentals of building a graphical user interface (GUI) calculator using PyQt5 and Python. Learners begin by setting up their development environment and understanding key dependencies. The module guides them through the step-by-step process of designing the calculator interface, implementing functional buttons, and embedding logical operations. By the end, learners will be able to create and test a working calculator application that performs basic arithmetic operations within a custom PyQt GUI layout.
