To change the character limit for the Black Python formatter, you can add a file named [pyproject.toml](https://www.python.org/dev/peps/pep-0518/) with the following:
[tool.black] line-length = 80 in your project directory.
This change is permanent but will work only in the project with the mentioned file. As of July 2020, I haven’t found a way to make this change permanent globally to a Python environment
