How can I pass arguments to the python interpreter like "-u" in launch.json configurations?

I am trying to call python -u file.py in VS Code debug mode. I get that I can use the "args" field to specify arguments, but what about python interpreter flags?

>Solution :

If you’re using "type": "python" in your launch configuration, just use the "pythonArgs" field and pass an array of arguments (as strings) to pass to the python interpreter.

That field’s description:

Command-line arguments passed to the Python interpreter. To pass arguments to the debug target, use "args".

For example:

{
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": true,
            "pythonArgs": ["-u"]
        }
    ]
}
