Hello World

A minimal Python program that prints Hello World! to the terminal. It serves as a test and reference for the basic elements of a simple Claude Code Python repository.

The message has one new line before it and a blank line left after it.

Design

The program is split into two files:

• application.py holds a single class, Application, which exposes a single method, run, that prints Hello World! to the terminal.
• main.py holds the main function, which creates a new instance of Application named application, and then calls application.run.

Requirements

• Python 3.x (uses only the standard library — no third-party packages required).

Usage

Run the program from the project root:

python main.py

Or use the launcher script, which can be invoked from any directory:

./run.sh

Output

Hello World!

The blank line above the message is the single new line before the Hello World! string, and the blank line below it is the new line left after the message.
