Read-only TOML support is in the standard library since Python 3.11, though. And it's based on an easily obtained third-party package (https://pypi.org/project/tomli/).
(If you want to write TOML, or do other advanced things such as preserving comments and exact structure from the original file, you'll want tomlkit instead. Note that it's much less performant.)
