BAD: Using dicts or 3+ element tuples for ad-hoc data types. - **Linting/formatting**: Use `ruff`. - **Language version**: Assume Python 3.12+: tomllib, typing features, etc. - **Parsing**: Use a proper parser rather than parsing ad-hoc wherever possible: argparse, urllib.parse, tomllib, etc. --- > Source: [lf-/dotfiles](https://github.com/lf-/dotfiles) — distributed by [TomeVault](https://tomevault.io).
