Learn Python 3 Programming with PysimpleGUI and Pydroid 3 on Android Devices to Master Graphics Programming.

Introduction:
Programming on Pydroid 3 is a great way to develop Python programs on your Android device. With Pydroid 3, you have a Python IDE, interpreter, and a full-featured development environment right on your Android device. In this tutorial, we will cover how to use Pydroid 3 along with PySimpleGUI to create graphical user interfaces on Python 3 on Android devices.

Step 1: Install Pydroid 3
The first step in programming on Pydroid 3 is to install the app from the Google Play Store. Once you have installed the app, open it and you will see a screen with a Python console and a file browser.

Step 2: Setting up the environment
To start programming, you need to create a new Python script by tapping on the "+" button in the top right corner of the app. You can then start writing your Python code in the editor window.

Step 3: Installing PySimpleGUI
PySimpleGUI is a Python library that makes it easy to create graphical user interfaces. To install PySimpleGUI on Pydroid 3, you need to open the "Pip" tab in the app and type in the command "pip install PySimpleGUI". This will install the PySimpleGUI library in your Pydroid 3 environment.

Step 4: Writing your first GUI program
Now that you have installed PySimpleGUI, you can create your first graphical user interface program. Let’s create a simple program that displays a window with a button. Copy and paste the following code into your Python script:

import PySimpleGUI as sg

layout = [[sg.Button('Click me')]]

window = sg.Window('Hello PySimpleGUI', layout)

while True:
    event, values = window.read()
    if event == sg.WIN_CLOSED:
        break

window.close()

This code creates a window with a button that says "Click me". When you click the button, the window will close. This is just a simple example to get you started with PySimpleGUI.

Step 5: Running your program
To run your program, tap on the play button in the top right corner of the app. This will run your Python script and display the graphical user interface on your Android device.

Conclusion:
Programming on Pydroid 3 with PySimpleGUI is a great way to develop graphical user interfaces on your Android device using Python 3. With Pydroid 3, you have all the tools you need to write and run Python programs right on your Android device. I hope this tutorial has been helpful in getting you started with programming on Android devices using Python and PySimpleGUI. Happy coding!
