Changes Made

Added hello.py — a simple Python script that prints Hello, World! to stdout.

The script includes:

1. A module-level docstring ("""A simple hello world script.""")
2. A main() function with its own docstring that calls print("Hello, World!")
3. An if __name__ == "__main__" guard that invokes main()

Test result: PASS — running python3 hello.py outputs Hello, World! as expected.
