The proper way to config in the Settings GUI pane is with --line-length and the desired value as separate items:

"python.formatting.blackArgs": ["--line-length", "110"]

Answer 2

Well, I was fighting with new VSCode settings myself. I tried all things suggested in the other answers with many variations, and result was nil.

--line-length=80  

Answer 3

My setting is: "python.formatting.blackArgs": ["--line-length=110"] and it's working correctly. The equal sign was missing in your user settings.json

Answer 4

The examples of formatter-specific settings show the following:

"python.formatting.autopep8Args": ["--max-line-length", "120", "--experimental"],
"python.formatting.yapfArgs": ["--style", "{based_on_style: chromium, indent_width: 20}"]

So try:

"python.formatting.blackArgs": ["--line-length", "80"]
