How to pass an argument to the python interpreter (not to the python code) in VS code via launch.json

Question

I would like to pass the "-q -X faulthandler" arguments to the python interpreter in VS code launch.json but I have not found a solution yet (args passes argument to the .py file).

So the command would look like this in the teminal:

python** -q -X faulthandler** main.py --arg1 --arg2

Thank you!

I've read the VS code documentation but I have not found any description for this. I've tried to execute the python script in VS code with the following lauch.json options (neither worked):

1, "type": "python -q -X faulthander", "cwd": "${workspaceRoot}", "request": "launch", "program": "main.py",

2, "type": "python", "cwd": "${workspaceRoot}", "request": "launch", "program": "- q -X faulthandler main.py",

pythonArgs: Specifies arguments to pass to the Python interpreter using the syntax "pythonArgs": ["<arg 1>", "<arg 2>",...]. — JialeDu

According to the official documentation, in launch.json you can add pythonArgs configuration to specify parameters for the interpreter.

Another way is to install the Code Runner extension, and then search for Code-runner: Custom Command in setting to customize the execution command.

Or add the following configuration directly in settings.json to have the same effect.

    "code-runner.customCommand": "python $fileName",

After the configuration is complete, use Ctrl+Shift+P --> Run: Cunstom Command(Ctrl + Alt + K) to execute the code.

Hi.Thanks! I am testing it. In general I do not like that VS code does not properly show what is the command that is executed in its terminal so I can not see wether these arguments are really passed to the interpreter. I've found someone reporting a bug recently github.com/microsoft/vscode-python/issues/19810... so I tried with python.terminal.launchArgs fist. Unfortunately this does not seem to pass the params. (code stopped with no warnings/error but in the native terminal window I god a proper error message). So now I try with "pythonArgs": ["-q", "-X", "faulthandler"]. let's see..

The "pythonArgs": ["-q", "-X", "faulthandler"] works fine! Also VS code displays the error! Thanks once again!
