2.6 GUI development with QT5 and PyQt5

It is now time for a more systematic introduction to Python GUI development with QT5 and PyQt5. We will split this introduction into two parts, first showing you how to create GUI programmatically from Python code and then familiarizing you with the QT Designer tool for visually building GUIs and then translating them to Python code. In the walkthrough from Section 2.7, you will then work through a larger example of creating a GUI based application.
