hngocuyen/dinhtiendu-challenge ? reverse-engineered prompt

I’ve got a tiny Python 3.12 challenge repo with one obfuscated script called obf helloworld.py.

Please help me figure out what it does, then rewrite it into a clean, readable version that behaves the same way. If there’s any weird obfuscation or trick in the code, explain it in simple terms as you go, and keep the final result working in Python 3.12.

If it helps, you can check current Python docs online for anything version specific. I mainly want a clear, easy to understand version of the script, plus a short explanation of how the original works and what it prints or returns.
