How to Assign Functions to Words in QLabel using PyQt5

When developing a PyQt5 application, you might find yourself wanting to create an interactive QLabel where specific words trigger different functions when clicked. This could enhance user experience by providing an engaging interface. In this guide, we'll explore how to achieve this by leveraging the HTML capabilities within QLabel and connecting the text links to specific functions.

The Problem: Connecting Clickable Words to Functions

You have a QLabel that contains certain words, and you want each of these words to perform a particular action when clicked. For example, clicking on "Word1" should execute function1, and clicking on "Word2" should execute function2. The challenge comes when trying to connect these words in QLabel to the respective functions. Let’s dive right into the solution!

The Solution: Using HTML in QLabel

Step 1: Setup the Main Window

First, set up your main application window using the QWidget and QMainWindow classes. Here is how you can initialize your window:
