title: VSCode running Python 2 instead of 3
body: <p>I am using Python with VSCode, and if I use Cmd+Shift+P and type Run Code, it runs the code with Python2 even though I have specified it to use Python3. I have read this tutorial:
  <a href="https://stackoverflow.com/questions/53110324/how-to-force-vscode-to-use-python-3-instead-of-python-2">How to force VSCode to use Python 3 instead of Python 2?</a>
  but I do not understand how to change it. (and I can't comment because I don't have enough reputation yay)
  Could anyone help? Thanks!</p>
  
  <p>Maybe it could be related to the fact that the mini terminal at the bottom runs "python -u " instead of "python3 -u "? Does anyone know how to change that?</p>
