vscode python debug with arguments syntax error in launch.json

Question

I followed the microsoft doc and tried the following SO post. Currently I'm debugging via Python: Current File, and my launch.json is as follow:

{
    // 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",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": ["saveData","-s","XYZ"]
        }
    ]
}

and I'm experiencing the following error

File "/home/XD/miniconda3/envs/drl/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
File "/home/XD/miniconda3/envs/drl/lib/python3.6/runpy.py", line 85, in _run_code
    exec(code, run_globals)
...
File "/mnt/c/Users/XD/Documents/folder.vscode/launch.json", line 2
    // Use IntelliSense to learn about possible attributes.
     ^
SyntaxError: invalid syntax

My main script is as follows:

if __name__ == "__main__":
    parser = argparse.ArgumentParser(description='Choose Task')
    subparser = parser.add_subparsers(dest='subcommand',help='sub-command help')
    parser_sd = subparser.add_parser("saveData")
    parser_sd.add_argument('-s','--Symbol', type=str, required=True)
    parser_sd.add_argument('-f','--fileDest',type=str,default=None)

What is wrong with it?

@smaillis Have you ever tried to run this script in the cmd window? Can it run successfully or does the same issue occur? It is recommended that you could check the code writing and format. In addition, it will be better solved if you could provide complete code information, especially the codes near code lines 85 and 193. — Jill Cheng

This is an easy mistake to make: you edit the launch.json file, then start debugging and get the error you mentioned. It means that you're trying to run/debug the launch.json file itself, rather than your code.

Switch to the tab containing your code, then start debugging.

(as mentioned by @rioV8 in the comments, but this is an easy enough mistake to make that it seems worth an answer).

FACE. PALM. Also, EYE. ROLL. I'm really hoping there's a way to prevent this by setting up a particular file to be debugged or something like that.
