Additional arguments when running python scripts in terminal

[BeyondAntares]

Whenever I execute python code, I find additional arguments being printed prior to inteded executable outputs. These include

• file location of the Python interpreter
• location of .vscode extensions
• tvsd launcher file location
• launcher conditions
  --defaul, --nodebug, --client, --host localhost, --port 59106
• Python file location

I believe these have been enabled by an extension, but I don't want them to be printed everytime. How do I prevent additional arguments from being printed and just view the inteded out in the terminal?

NB: I'm using the anaconda bash terminal, but the error is present with command prompt and powershell.

Environment data

Expected behaviour

Normal execution of code no additional arguments

Actual behaviour

$ "C:\Program Files\Python37\python.exe" c:\Users\USERNAME\.vscode\extensions\ms-python.python-2019.9.34911\python
Files\ptvsd_launcher.py --default --nodebug --client --host localhost --port 59106 c:\Users\USERNAME\Documents\Code\P
ythonSocket\Client.py

Thanks for reporting this issue.

You are running the code by using the Debug -> Start Without Debugging option.
In such situations, VS Code uses the extension debugger API to run code (this is a VS Code design implementation).
As the debugger is used to launch the code on the users behalf, the arguments such as ptvsd_launcher.py --default --nodebug are passed into the interpreter.

Unfortunately there's nothing we (Extension) can do about this as this is the architectural decision made by the VS Code team.

If you do not wish to see such arguments being passed into the interpreter and want to just run code in the terminal, then please consider using the command Python: Run Python File in Terminal, this is also available as a menu item in the context menu for a python file.

Closing as this is by design (upstream VS Code).
