Tkinter is Python library which can be used to make GUI Application in Python. This is available in python by default.

In this article, we would explain the various functionalities available in Tkinter and also create a sample GUI Application which would look like below

Please refer the videos below for detailed explanation on how to use Tkinter to create GUI elements in Python

We have taken article from following webpage as reference

Please refer the following code to understand on how to create GUI elements using Tkinter in Python
