PyQt5 Introduction

Those who work with Linux have probably heard of QT. QT is a cross-platform C++ development library primarily used for developing graphical user interfaces (GUI). PyQt, developed by Digia, is a Python-based interface for the QT framework, consisting of a series of Python modules. Simply put, it allows you to develop GUIs using Python programming.

Life is short, and the advantage of PyQt is that it retains QT's underlying execution efficiency while improving development efficiency. You no longer need to program in C++. As long as you know Python and use QT Designer (QT's visual interface programming tool), you can easily create your own GUIs.

The "5" in PyQt5 is the version number, which is not backward compatible. It is currently the most popular and most well-documented version on the market. We hope this chapter's tutorial helps you quickly learn how to develop PyQt5 and deploy it on WalnutPi.
