Within the numpy codebase we aim to keep the maximum line length at 88 (#27320). We will enforce the ruff E501 rule for the codebase step by step:

List of files to be handled can be found in the ruff.toml file.

Procedure:

1. Select a couple of files to fix (for example all python files in numpy/random)
2. Update ruff.toml to enable ruff E501
3. Change python files to have maximum line length 88
4. If some formatting really is better with longer lines, use # noqa: E501 to make an exception
