Introduction to Kivy in python

In this article we look at Kivy and create our first example using Python

Kivy is a free and open source Python framework for developing mobile apps and other multitouch application software with a natural user interface (NUI). It is distributed under the terms of the MIT License, and can run on Android, iOS, Linux, macOS, and Windows.

Installation in Windows:

Step 1: Update the pip and wheel before installing kivy by entering this command in cmd-

python -m pip install –upgrade pip wheel setuptools

Step 2: Install the dependencies-

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy.deps.gstreamer
python -m pip install kivy.deps.angle

Step 3: Install kivy.

python -m pip install kivy

I used Thonny, click on Tools -> manage Packages -> search for Kivy and install, its all done for you easy

Code example

There are three basic steps of creating an application using kivy:

Inherit Kivy’s App class which represents the window for the widgets
Create a build() method, which will show the content of the widgets.
And at last calling of the run() method.

import kivy
from kivy.app import App
from kivy.uix.button import Label
# HelloKivy inherits all the fields and methods from Kivy
class HelloKivy(App):
    # This returns the content we want in the window
    def build(self):
        # Return a label widget
        return Label(text ="Maxpython")
helloKivy = HelloKivy()

When you run this you will see something like this
