🔗 VSCode: Setting line lengths in the Black Python code formatter
dev.to
The docs for the Black Python code formatter say that the formatter "is not configurable". This is largely true, but if you have Black set up > to work in VSCode, you can configure the line length.
In VSCode, go 'Code -> Preferences -> Settings' and search for "python formatting black args".
Add two separate arguments, in this order:
--line-length
andn
, where "n" is your desired number of allowed characters per line.A few notes about line lengths in Python:
- PEP8 recommends a line length of [79 characters]https://www.python.org/dev/peps/pep-0008/#maximum-line-length (72 for docstrings)
- Black sets line lengths to 88 characters by default
- The Django docs recommend a maximum line length of 119 characters (79 for docstrings)
If you are working on a shared project with a team, consider bypassing the VSCode settings entirely, and setting line lengths via the project's
pyproject.toml
:1[tool.black] 2line-length = 119
Note to self, if you want to add it to the VS Code workspace settings, add this:
1{
2 "[python]": {
3 "editor.defaultFormatter": "ms-python.black-formatter"
4 },
5 "black-formatter.args": ["--line-length", "119"]
6}
