Debugging with arguments does not work with spaces in path to python.exe

[spkl]

Type: Bug

Behaviour

When the path to the python.exe contains spaces (e. g. c:\Program Files\Python311\python.exe), debugging with arguments is not possible.

The terminal shows the following:

PS C:\Data\Temp\py>  c:\Program Files\Python311\python.exe c:\Users\SebastianF\.vscode\extensions\ms-python.debugpy-2024.4.0-win32-x64\bundled\libs\debugpy\adapter/../..\debugpy\launcher 53374 -- C:\Data\Temp\py\script.py aaa 
c:\Program: The term 'c:\Program' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

After a few seconds, an error dialog "Timed out waiting for launcher to connect" appears.

Depending on the path, a workaround can be used by specifying a path with shortened names, e.g. c:\Progra~1\Python311\python.exe. This is not easily discoverable.

Steps to reproduce:

Precondition: In the settings, the python default interpreter path contains spaces.

1. Create a .py file and type some code
2. Press F5
3. Select "Python Debugger"
4. Select "Python File with Arguments"
5. Type some command line arguments and confirm

Hey!

I am have the exact same problem.

Added information: I was following this guide to enable debugging Python with command line arguments: https://devblogs.microsoft.com/python/python-in-visual-studio-code-august-2023-release/ > Debugger configuration for running files with arguments

This is the launch.json that got created in the process:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Debugger: Current File with Arguments",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": "${command:pickArgs}"
        }
    ]
}
