This hands-on guide shows you how to build desktop applications with Python and the PyQt5 framework. PyQt is a powerful toolkit, but its documentation can be overwhelming — this book focuses only on what you need to get started. You'll learn how to use widgets, layouts, signals, and events to build responsive apps. Along the way, you’ll create practical projects like a BMI calculator, a web browser, and a text editor using Qt Designer and Python. By the end, you’ll be confident building and customizing your own software for Windows, macOS, or Linux.
