Can the Code Runner extension in VS Code use the selected kernel when running a piece of code?

Question

I'm new to programming and I'm setting up setting up Visual Studio Code to start learning some Python. I've got the following setup:

• MacOS 10.6.4 (I've got a system Python 2.7.16)
• installed Anaconda ('base' environment with Python 3.9.7 and 'Python310InclCoreDS' environment with Python 3.10.4)
• installed Visual Studio Code 1.66.2
  • ext: Python 2022.4.1
  • ext: Pylance 2022.4.3
  • ext: Jupyter Notebook Renderers v1.0.6
  • ext: Jupyter Keymap v1.0.0
  • ext: Jupyter 2022.3.1000901801
  • ext: Code Runner 0.11.7
  • ext: Black Formatter v2022.1.11231003

Now I have some trouble understanding the way the Code Runner extension picks it's Python version. See the screenshot below.

• Whenever I run a complete regular Python file (.py) the Python kernel picker works as expected and the selected Python version is used. (This scenario is not in the screenshot.)
• Whenever I run a code cell in a Jupyter notebook using the "Execute Cell" button the Jupyter kernel picker works as expected and the selected Python version is used. (This scenario is shown in my screenshot in red.)
• Whenever I select a piece of code using Code Runner in either a regular Python file (.py) or a Jupyter notebook the kernel pickers don't work as expected. I've noticed it will use my system Python 2.7.16 if terminal.integrated.inheritEnv=True. (This scenario is shown in my screenshot in blue.) It will use my Python 3.9.7 Anaconda environment when terminal.integrated.inheritEnv=False. (This scenario is not in the screenshot.)

Now I wonder: can Code Runner when running a piece of code also use the selected kernel (either when executing a piece of a.py file, or when executing a piece of a Jupyter notebook)?

Solution summary
Quick summary of the solution, because part of it is in a comment below. You need to configure the Executor Map of Code Runner as described below. Apart from that, Code Runner always uses the kernel selected in the Python extension, never the one from the Jupyter extension.

Answer 1

This should be related to the default Python interpreter used by code-runner, which you can change in setting.json.
