Hello World in Kivy

  • Difficulty Level : Easy
  • Last Updated : 28 Jan, 2020

Kivy is an opensource multi-platform GUI development library for Python and can run on iOS, Android, Windows, OS X, and GNU/Linux. It helps develop applications that make use of innovative, multi-touch UI. The fundamental idea behind Kivy is to enable the developer to build an app once and use it across all devices, making the code reusable and deployable, allowing for quick and easy interaction design and rapid prototyping.

Note: Since Kivy is based in Python, Python is a prerequisite before installing Kivy. For more information, refer to Python Programming Language.

There are several ways to get Kivy installed in your system, depending upon your Operating System. Let’s dive into it.
Windows OS

  • Using pip
    pip install kivy
  • Using conda
    conda install -c conda-forge kivy


  • Add the PPA using the following command:
    sudo add-apt-repository ppa:kivy-team/kivy
  • Update your package list using your package manager-
    sudo apt-get update
  • Install Kivy
    sudo apt-get install python3-kivy


  • Using Wheels
    Wheels are precompiled binaries for the specific platform you are on. All you need to do to install Kivy using wheels on osx is
    $ python -m pip install kivy

Hello World in Kivy

  • Let’s create a Python file i.e. with .py extension.
  • First of all let’s import kivy and ensure it’s up-to-date.
    import kivy
    # Replace this with your 
    # current version
    # To find your kivy version use,
    # print(kivy.__version__)
  • Now to create a Kivy interface we need to import Kivy App module in our program using the following code:
    from import App
  • Now import Label from kivy.uix.label
    from kivy.uix.label import Label
  • Now let’s write main block that prints Hello World, yayy finally!!
    class MyFirstKivyApp(App):
        def build(self):
            return Label(text ="Hello World !")

Complete Program

import kivy
from import App
from kivy.uix.label import Label
# Replace this with your 
# current version
# Defining a class
class MyFirstKivyApp(App):
    # Function that returns 
    # the root widget
    def build(self):
        # Label with text Hello World is 
        # returned as root widget
        return Label(text ="Hello World !")          
# Here our class is initialized
# and its run() method is called. 
# This initializes and starts 
# our Kivy application.
