Question -- How to link Sublime Text 3 Build system (Build 3211) to Python 3.9 Using Windows 10

Am trying to use Sublime Text 3 (Build3211) with Python 3.9.0 on Windows 10.
Have downloaded both successfully and

  1. Gone to Sublime Text to: Tools -> Build System -> New Build System
    and put the next lines:

“cmd”: [“python3”, “-u”, “$file”],
“file_regex”: “^File “(…?)”, line ([0-9]*)”,
“selector”: “source.python”

Then saved it with the name: python3.sublime-build
But when I write a program like:

print(“Help”) and run under Sublime Text to Tools Python 3, I get the following message:

Python was not found but can be installed from the Microsoft Store:[Finished in 0.3s]

Am just beginning to learn how to code… PLEASE HELP!
