Vs Code Python + Black Formatter Arguments - Python.formatting.blackargs

I'm using the May 2018 Python extension (released June 2018) for VS Code 1.23.1 on Windows, python 3.6 via Anaconda, conda installing black from conda-forge into my conda environme

Solution 1:

The issue is that you need =80 instead of 80 after --line-length for version 1.38.1 and above:

--line-length=80

Solution 2:

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"]

Solution 3:

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

Visual Studio Code GUI Settings for Python Formatting

This converts into the settings.json into this:

Visual Studio Code JSON Settings for Python Formatting

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

Solution 4:

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