In this video I’ll show you how to update labels in your Kivy app based on user input.

Updating labels and other things based on user input is a fundamental part of building any app. Fortunately it’s pretty easy to update a label. In this video I’ll show you how to enter text in a text box, click a button, and then update a label with whatever you typed into the button.

Python Code:
GitHub Code:

from import App
from kivy.uix.widget import Widget
from import ObjectProperty
from kivy.lang import Builder

# Designate Our .kv design file 

class MyLayout(Widget):
	def press(self):
		# Create variables for our widget
		name = self.ids.name_input.text
		# Update the label
		self.ids.name_label.text = f'Hello {name}!'

		# Clear input box
		self.ids.name_input.text = ''

class AwesomeApp(App):
	def build(self):
		return MyLayout()

if __name__ == '__main__':

Kivy Design Code: update_label.kv
GitHub Code: update_label.kv

		orientation: "vertical"
		size: root.width, root.height
			id: name_label
			text: "What's Your Name?"
			font_size: 32

			id: name_input
			multiline: False
			size_hint: (1, .5)

			size_hint: (1, .5)
			font_size: 32
			text: "Submit"
