An error with vscode.

I recently bought a book on how to use Python the book is called "Python for dummies". I was trying to create a workspace in vscode and in the book it was said that you should click the 3 buttons on the top right corner and from there it will say opensettings.json. However this did not appear and I am unsure why. If anyone knows if there is a problem then I would be grateful if you shared it. Also I did try in vscode and my post was taken down for some reason.
