How to Add a Scrollbar in a Text Widget Using Tkinter in Python

If you are working on a GUI application with Python's Tkinter library and need to include a text widget that supports scrolling, you might encounter challenges, especially when trying to use the place geometry manager. Many guides suggest using the pack manager, which can be less flexible than place. Let’s explore how to solve this issue effectively.

Understanding the Problem

When utilizing the place geometry manager in Tkinter, it can be tricky to integrate a scrollbar into a text widget. The place manager allows for precise control over the position of widgets, but you may find that the traditional approach to adding scrollbars does not work well in this scenario. The objective is to add a scrollbar to a text widget while maintaining control over its placement in your GUI.

The Solution: Using tkinter.scrolledtext

Fortunately, Tkinter has a built-in module called tkinter.scrolledtext, which simplifies the process of adding scrollable text areas without extra complex setups. Here's how you can implement it step-by-step.

Step 1: Import the Required Libraries

To get started, you need to import the required modules from Tkinter:
