Running python program fails, please help!

Hi,

Ok so first of all, I am sorry for creating another topic. I was able to find a similar error which was discussed here previously:

That's the same issue I am facing.

I see the solution recommended is to add the full path to python exe like so:

C:\Users\user x\AppData\Local\Programs\Python\Python36\python.exe"

Which 'user' would that be?

Thank you.
