Toga, a part of BeeWare, is specifically designed for building cross-platform applications. Key Features: Write once, run anywhere Native look and feel Supports iOS, Android, Windows, macOS, Linux, and more Access to native APIs Getting Started: pip install toga Pyqtdeploy Pyqtdeploy is a deployment tool that facilitates the packaging and distribution of PyQt applications. While PyQt itself is primarily for desktop applications, pyqtdeploy extends its capabilities to cross-platform deployment. Key Features: Efficient packaging and distribution Supports Windows, macOS, and Linux Cross-compilation support Easy integration with PyQt applications Getting Started: pip install pyqtdeploy From the resource library of andolasoft.inc Page 4

5. BeeWare - Briefcase Briefcase is another component of the BeeWare suite that focuses on packaging Python projects into standalone applications. It supports creating executables for various platforms, including mobile. Key Features: Simplifies the packaging process Supports iOS and Android Integration with other BeeWare tools Getting Started: pip install briefcase 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: From the resource library of andolasoft.inc Page 5

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) From the resource library of andolasoft.inc Page 6

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 1.Simplicity and Readability: Python's clean and readable syntax makes it an ideal choice for developers. Its simplicity allows for faster development cycles, crucial in the ever-evolving landscape of mobile applications. From the resource library of andolasoft.inc Page 7
