I am running a Python program that takes some command line arguments. How can I provide these arguments when I am building a program within the Visual Studio Code?

1You can put the parameters in the properties dialog of your project.gplayer– gplayer2016-10-14 07:11:18 +00:00Commented Oct 14, 2016 at 7:11

You can pass in the arguments into the program by defining the arguments in the args setting of launch.json as defined below:
json
{
"name": "Python",
"type": "python",
"pythonPath":"${config.python.pythonPath}",
"request": "launch",
"stopOnEntry": true,
"console": "none",
"program": "${file}",
"cwd": "${workspaceRoot}",
"args":["arg1", "arg2"],
"env": {"name":"value"}
}
Further information can be found on the documentation site here: https://github.com/DonJayamanne/pythonVSCode/wiki/Debugging#args

This works, but in the debug mode. Is it possible to make it run in the non-debug mode?
Alex
@cerebrou you ever find an answer for this?

Not the right answer: This only works for debugging (as cerebrou already pointed out)
Don
You can use
Run without debugging option, it'll still use the same options and it will not debug your code

@CoryKramer can you give a hint on how to add a console argument for python executable itself (not the program)? I just need to run "python -i <scriptfile>" so I can continue in the integrated console. I am struggling with the docs and forums for just a simple thing like that and I can't find it.

If you use the Code Runner extension you can add the following to your settings (click on the '{}' icon in the top right corner to get the settings.json file):
"code-runner.executorMap": { "python": "$pythonPath -u $fullFileName xxx" }
where xxx is your argument. This is a global change so you have to change when working on other files.

A better method would be to just keep it simple and run the command manually from the terminal and supply the necessary command line arguments. Or better yet, use a Makefile with custom targets. I find code runner works best for running programs without command-line arguments.

As it’s currently written, your answer is unclear. Please edit to add additional details that will help others understand how this addresses the question asked. You can find more information on how to write good answers in the help center.
One way to do it in the version 2.0.0 is:
"command": "python ${file} --model_type LeNet5 --prior_file conf1.json --epochs 200",

where do you add this? launch.json is for debugging, isn't
running your script from the command line in the terminal works.

slow
but then you can not debug it. or how would you do it?
I was also looking for an answer for this. Setting in launch.json works, but you can only use debugging afterwards and if you have more that one configuration, it makes it hard to go back and forth.
So I write a simple function that I can load in main app file. You can give your args with a json file with this method and it works for both debugging and normally running script
import sys
import json
def loadArgs(path):
with open(path) as args_file:
args = json.load(args_file)
for arg in args:
name = '--' + arg
value = args[arg]
if name not in sys.argv:
sys.argv.append(name)
sys.argv.append(value)
print('Args are loaded...')
And import in your main file
from set_args import loadArgs
loadArgs(path='args.json')
