Introduction
Kivy is an open-source Python toolkit for quickly developing applications with novel user interfaces, like multi-touch apps. It is mostly used to create Android applications, but it may also be used to create desktop applications. In this blog, we'll look at how to add labels to Kivy-created windows.
Widgets and Labels
The goal behind widgets is to have a collection of different types of elements that we can combine to make an application. Consider a login page on a home page. You may have text on your home page that says things like "username" and "password." After that, you'll need some text fields for input. To do this using Kivy, we'll use a Label widget to hold the content and then a text input widget to allow the user to type something.
Creating a label
The Label widget is used to display text. It can handle both ASCII and Unicode text. It is the text that we want to put on our windows, buttons, and other elements. We can also add styling to labels, such as increasing the text size, color, etc.
In the example below, we construct a window and use the Label method from the uix.label module to assign it a customized label. A new window appears with the custom label when we start the app with this code.
from kivy.app import App
from kivy.uix.label import Label
class NewLabel(App):
def build(self):
# Label text to be edited
label = Label(text ="Hello Label Text ! ")
return label
NewLabel().run()

When we run the code above, we get the following result:
Decorating a label widget
Additional arguments available as part of the Label widget function can be used to change the colour and font size of the label.
from kivy.app import App
from kivy.uix.label import Label
class MyApplication(App):
def build(self):
# Label text to be edited
label = Label(text ="Hello World!! \nThis is a decorated label",font_size='30sp',color = [0.56, 0.56, 0.24, 1])
return label
MyApplication().run()

To change the size, use text size to confine the text and/or bind size to texture size to let the text to grow with it.
How to add multiple lines to a label?
Using 'n' at the end of a line, you can easily make the text multiline.
