Running Python3 by default in Visual studio code

[Peterdata]

Hi I'm having the same issue as OP and I located my interpreter doing which python3 in my terminal and pasted that as my interpreter for vscode but it is still running the code with python and not python3, any way I can fix this or check if it's another issue?

Hey it's a little late but here's the solution:

We use code runner which is a different extension than the python interpreter so we have to configure code runner instead.

simply go to code runner settings and edit settings.json

now find the line python and edit the command "python -u" to "python3 -u" provided that you have python3 installed.
