vscode: debugging python scripts with args

On the top, left side of VSCode, find your debugsettings files by going to the gear icon.

In launch.json you should see pre-populated settings that looks something like:

{
// 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: Current File (Integrated Terminal)",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        },
    ]
}

For scripts, that require args you can update the json configuration to look something like this:

"configurations": [
    {
        "name": "Python: Current File (Integrated Terminal)",
        "type": "python",
        "request": "launch",
        "program": "/Users/<username>/<path>/<to>/<file>/<file_name>.py",
        "console": "integratedTerminal",
        "args": ["-p","<project_name>", "-k", "<key_name>"]
    },
]

If you get an error that a Python Interpreter is missing:

You need to select a Python interpreter before you start debugging. Tip: click on "Select Python Interpreter" in the status bar.

You can fix it by making sure that there is a virtual environment in the same root directory you are using the debugger. VSCode will auto-detect and activate the venv for you, and then know which Python interpreter to use.
