How to Create a GUI in Python

Have you ever wished to create a Graphical User Interface (GUI) in Python? If you have, then you have come to the right place. Python is a high-level programming language that is easy to learn, versatile, and powerful. It has an extensive library of modules and packages that make it a favorite among developers. In this article, we will be exploring how to create a GUI in Python. We will cover everything from the basics of GUI programming to creating complex interfaces using third-party libraries. So, let’s dive in.

What is a Graphical User Interface (GUI)?

A Graphical User Interface (GUI) is a type of user interface that allows users to interact with electronic devices using visual elements such as icons, buttons, and menus. GUIs are popular for their ease of use, simplicity, and interactivity. They are used in a wide range of applications, from operating systems to video games.

GUI Programming in Python

Python is a popular programming language for GUI programming due to its simplicity, versatility, and powerful libraries. The most popular libraries for GUI programming in Python are Tkinter, PyQt, PySide, and wxPython. In this article, we will be focusing on Tkinter, which is a built-in library in Python.

Installing Tkinter

Before we dive into creating a GUI using Tkinter, we need to ensure that Tkinter is installed on our system. Tkinter is included with standard Python installations, so we do not need to install it separately. To check if Tkinter is installed on your system, open the Python shell and enter the following command:

import tkinter

If the command runs without any errors, then Tkinter is installed on your system. If you get an error message, then you need to install Tkinter using the following command:

sudo apt-get install python-tk

Creating a GUI Using Tkinter

Now that we have Tkinter installed on our system, we can start creating a GUI. The first step is to create a Tkinter window, also known as a root window. We do this using the following code:

import tkinter as tk

root = tk.Tk()

The above code creates a new Tkinter window and runs it in a loop until the window is closed. The window will be empty, so we need to add some widgets to it.


Widgets are the visual elements that make up a GUI. In Tkinter, there are several types of widgets, including buttons, labels, text boxes, and menus. To add a widget to a Tkinter window, we use the pack() method. The pack() method is used to place widgets in a specific location on the window.

import tkinter as tk

root = tk.Tk()

label = tk.Label(root, text="Hello, World!")


The above code adds a label widget to the Tkinter window with the text "Hello, World!". The pack() method is used to place the label widget in the center of the window.


Buttons are another type of widget in Tkinter. To create a button, we use the Button class.

import tkinter as tk

root = tk.Tk()

def clicked():
    print("Button clicked!")

button = tk.Button(root, text="Click Me", command=clicked)


The above code creates a button widget with the text "Click Me". When the button is clicked, the clicked() function is executed, which prints "Button clicked!" to the console.

Text Boxes

Text boxes are widgets that allow users to enter text. To create a text box widget, we use the Entry class.

import tkinter as tk

root = tk.Tk()

def submit():
    print("Name:", name.get())

label = tk.Label(root, text="Enter your name:")

name = tk.Entry(root)

button = tk.Button(root, text="Submit", command=submit)


The above code creates a label widget with the text "Enter your name:", a text box widget, and a submit button. When the user clicks the submit button, the submit() function is executed, which prints the name entered in the text box to the console.


In conclusion, creating a GUI in Python is easy with the help of the built-in Tkinter library. Tkinter provides a wide range of widgets that can be used to create complex interfaces. In this article, we covered the basics of GUI programming in Python, including how to create a window, add widgets, and handle user input. With these skills, you can create powerful and interactive applications in Python.
