Introduction to Python GUI Libraries: PyQt and Kivy


Graphical User Interfaces (GUIs) are a crucial part of many software applications. Python provides various GUI libraries to create interactive desktop and mobile applications. In this guide, we'll introduce two popular Python GUI libraries: PyQt and Kivy. You'll learn about their features, use cases, and get started with some sample code.


Before you begin, make sure you have a Python environment set up. Additionally, install the following libraries using pip:

pip install PyQt5 kivy

PyQt: Python Binding for Qt

PyQt is a set of Python bindings for the Qt application framework. It allows you to create cross-platform GUI applications with ease.

Sample Code Using PyQt

Create a simple PyQt application that displays a window with a button:

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
def button_click():
print("Button Clicked!")
app = QApplication(sys.argv)
window = QMainWindow()
window.setWindowTitle("PyQt Example")
button = QPushButton("Click Me", window)

Kivy: Open Source Python Library

Kivy is an open-source Python library for developing multitouch applications. It is particularly suited for creating mobile applications.

Sample Code Using Kivy

Create a simple Kivy application that displays a button on a touchscreen-like interface:

from import App
from kivy.uix.button import Button
class KivyApp(App):
def build(self):
return Button(text="Click Me")
if __name__ == "__main__":


PyQt and Kivy are powerful Python GUI libraries that enable you to create interactive desktop and mobile applications. This guide has introduced you to the basics of both libraries, but there's much more to explore as you dive deeper into GUI application development.
