Requirements

1. A machine with no Python installed
   • I'm not sure how to get a new macOS machine with no Python installed, but for Windows you can create one on Azure and for Linux you can just open VS Code in a devcontainer with no Python installed
2. VS Code Insiders
3. Pre-release version of the Python extension

Steps

1. Open the walkthrough ("Get started... Open walkthrough" command, select "Get started with Python development")

2. Verify that no "No Python installed" notifications pop up

3. Verify all 4 tiles appear as expected:

   

4. Verify clicking on "Create Python file" creates an untitled Python file on the side:

6. Verify clicking on "Select Python Interpreter" shows a "Python is not installed" option in the drop down:

   

7. Clicking on it will show different things depending on the OS.

   • On Windows 10/11: Click on in the "install Python" button should open the latest version of Python in the Microsoft store. After installing Python is completed, verify the interpreter shows up the next time Select Interpreter button is clicked.
   • On macOS/Linux: It should open the tile with installation instructions. Verify clicking on the "Install Python via ___" button opens a terminal and fills in the suggested commands.

On Linux:

• I used sudo mv /bin/python3 /bin/python3.bak, then sudo mv /bin/python3.8 /bin/python3.8.bak, then mv ~/anaconda3/bin/python ~/anaconda3/bin/python.bak, then mv ~/anaconda3/bin/python3 ~/anaconda3/bin/python3.bak, then mv ~/anaconda3/bin/python3.9 ~/anaconda3/bin/python3.9.bak, then code-insiders to try to start VSCode insiders without Python.
• New window, then "Get started... Open walkthrough" then "Get started with Python development".
• I'm not getting the "No Python installed" notifications pop up.
• All 4 tiles appear as expected:

• Clicking on "Create Python file" creates an untitled Python file on the side. Also, at this point, I see a yellow "Select Interpreter" message at the bottom:

• By either clicking on the yellow message at the bottom, or going through the next section "Select a Python Interpreter" and clicking the "Select Python Interpreter", I get the following:

• Clicking on the "Python is not installed" option shows the following:

After installing Python via the Windows Store on a clean VM and clicking 'Select Interpreter' again, I initially get this

Clicking the refresh button in the top right of the quickpick results in the Windows Store Python install showing up. Not sure if that's expected?

@joyceerhl Could you please create an issue? I expect refresh to automatically be triggered when the list is opened without the need to use the refresh button.

@luabud, @karrtikr uninstalling python on macOS seems like a significant undertaking.
Can any of you please provide what is the recommended way to uninstall python from a clean macOS machine?

@lszomoru Can you try running Python: Select Interpreter command and delete every binary file listed there? #19550 (comment)

@karrtikr, I have spent hours today trying to delete /usr/bin/python3 without any luck. I have already disabled System Integrity Protection, but I am still getting sudo chown $(whoami):admin /usr/bin/. Any recommendation on how to move forward would be appreciated. Thanks!
