Installed Atom however script won't run

Hi All - new to Python and Atom so watched a few videos on how to install Python and Atom however I run into the below issue.

I have downloaded the Script package, and have Python installed to PATH. I even created the project folder within the same folder yet no difference.

When I disable the app execution aliases as mentioned, I get the below new error message:

“‘python’ is not recognized as an internal or external command, operable program or batch file.”

Any help would be appreciated because I’m quite confused

Thanks for the link.

Not sure what happened but once I restarted my laptop, it started to work.
