I'd be happy to help you create a simple Python application. Let's start with a basic "Hello, World!" program to get you started. Here's a simple Python script:

This script does the following:

1. We define a main() function that prints "Hello, World!" to the console.
2. The if __name__ == "__main__": block ensures that the main() function is only called if the script is run directly (not imported as a module).

To run this script, you would typically save it as hello_world.py and then run it from the command line using:

This will output:

Is there any specific functionality you'd like to add to this Python application? I can help you expand it with more features or explain any part of the code in more detail.
