Use :

Python3 Helloword.py

Or:

Python Helloword.py

You have to tell to OS this is a python file. You just wrote file name but didn't tell what's execute this.

make sure to use lowercase `python` or `python3` – shark Sep 14 '21 at 15:00
For Windows it doesn't matter – data_m Sep 15 '21 at 06:42
I don't use Windows, so I didn't know. But it's definitely good to lowercase everything because that's the standard for literally every other operating system, unless you alias it. Besides, it's one less keystroke for it, so why not? – shark Sep 15 '21 at 13:30
@shark you're right. – data_m Sep 15 '21 at 14:11
