Below we have explained the process of developing cross-platform mobile apps using
Python, accompanied by practical code examples to guide you through each step.
Understanding Cross-Platform Development
Before we start making things, let's quickly understand what cross-platform
development means.
Cross-platform development lets developers write code just one time and use it on
different platforms like iOS and Android.

This way, it saves a lot of time and resources because developers don't have to make
separate apps for each platform.
Top Python Frameworks for Cross-Platform Mobile App Development
As the demand for mobile applications continues to rise, developers seek efficient ways
to build apps that run seamlessly across different platforms.
Python, known for its versatility and readability, has become a popular choice for cross-
platform development.
Here is the list of various frameworks that empower developers to build cross-platform
mobile apps using Python.

Creating Your First Cross-Platform App
Let's start by creating a simple "Hello World" app to get a feel for the development
process.
# main.py
from kivy.app import App
from kivy.uix.button import Button
class HelloWorldApp(App):
def build(self):
return Button(text='Hello, Cross-Platform World!')
if _ _ name _ _ == ' _ _ main _ _ ':
HelloWorldApp().run()
Save the above code in a file named main.py and run it using the command:
6. From the resource library of andolasoft.inc Page 6
Python main.py
You should see a basic window with a button displaying the "Hello, Cross-Platform
World!" text.
Building a Cross-Platform Calculator App
Let's take things up a notch by creating a cross-platform calculator app.
# calculator.py
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
class CalculatorApp(App):
def build(self):
layout = BoxLayout(orientation='vertical', spacing=10)
self.result = Button(text='0', font_size=32, size_hint=(1, 0.2))
layout.add_widget(self.result)
buttons = [
['7', '8', '9', '/'],
['4', '5', '6', '*'],
['1', '2', '3', '-'],
['0', '.', '=', '+']
]
for row in buttons:
h_layout = BoxLayout(spacing=10)
for label in row:
button = Button(text=label, pos_hint={'center_x': 0.5})
button.bind(on_press=self.on_button_press)
h_layout.add_widget(button)
layout.add_widget(h_layout)
7. From the resource library of andolasoft.inc Page 7
return layout
def on_button_press(self, instance):
current_text = self.result.text
if instance.text == '=':
try:
result = str(eval(current_text))
self.result.text = result
except Exception as e:
self.result.text = 'Error'
else:
self.result.text += instance.text
if _ _ name _ _ == ' _ _ main _ _ ':
CalculatorApp().run()
This calculator app demonstrates the potential of Python and Kivy for cross-platform
app development.
Run it using the same python calculator.py command, and you'll have a fully functional
calculator on your screen.
The Python Advantage
