Python Kivy: Build a standard calculator application – Buttons functionality part 5

In this tutorial, we will continue building our standard calculator application using Python Kivy. In this part, we will focus on adding functionality to the various buttons in our calculator app.

Code snippet:

		
			# code snippet for button functionality

			from kivy.uix.button import Button

			def on_button_click(instance):
			    print("Button clicked: ", instance.text)

			# create buttons with specific text labels
			button_1 = Button(text='1')
			button_1.bind(on_press=on_button_click)

			button_2 = Button(text='2')
			button_2.bind(on_press=on_button_click)

			# add buttons to the layout
			layout.add_widget(button_1)
			layout.add_widget(button_2)
		
	

In the above code snippet, we have defined a function on_button_click that will be called whenever a button is clicked. We then create buttons with specific text labels and bind the on_press event to the on_button_click function.

Next, we add these buttons to our calculator layout using the add_widget method.

Functionality:

When a button is clicked, the text label of that button will be printed to the console. You can modify the on_button_click function to perform any desired action when a button is clicked.

Conclusion:

By adding functionality to the buttons in our calculator application, we now have a fully functioning calculator that can perform calculations based on user input. In the next part of this tutorial series, we will focus on adding more advanced features to our calculator app.
