pint.utils.open_or_use

pint.utils.open_or_use(f: str | bytes | Path | IO[Any], mode: str = 'r') → Generator[IO[Any], None, None]

Open a filename or use an open file.

Specifically, if f is a string, try to use it as an argument to open. Otherwise just yield it. In particular anything that is not a subclass of str will be passed through untouched.
