Prerequisites : Introduction to tkinter | Sentiment Analysis using Vader
Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. Python with Tkinter outputs the fastest and easiest way to create GUI applications. In this article, we will learn how to create a Sentiment Detector GUI application using Tkinter, with a step-by-step guide. 
To create a tkinter :
Importing the module – tkinter
Create the main window (container)
Add any number of widgets to the main window.
Apply the event Trigger on the widgets.
The GUI would look like below:
Let’s create a GUI based Sentiment Detector application that can show the sentiments with respect to the given sentences, given by the user. 
Below is the implementation : 
Python3
