How to run python3 code in VSCode? /bin/sh: 1: python: not found

I'm trying to run a python file in VSCode using python3.

I can run using integrated terminal like it says in the microsoft vscode tutorial on python. However, I would like the program to print in the output tab and not take up the terminal window. However I'm getting this error.

Clik here to view.

The standard code runner config file launch.json, looks like this;

"version": "0.2.0","configurations": [    {"name": "Python: Current File","type": "python","request": "launch","program": "${file}","console": "integratedTerminal"    }]

I've tried to set my python path in VSCode in settings.json

..."python.pythonPath": "python3","code-runner.executorMap": {"python3": "/usr/bin/python3"}

I've also set an alias for python -> python3 (as my ubuntu 20.04 doesn't come with python2 anymore)

alias python="python3"

However, I keep getting the above error. Any Ideas?
