Today, I learned how to set the minimum version of Python in pyproject.toml.
If I want a minimum version of Python:
[project] python = ">=3.10"
If I want a maximum version of Python:
[project] python = "<=3.10"
This problem came up within the context of llamabot, where I was using relatively new syntax to indicate the union of types:
doc_paths: List[str] | List[Path] | str | Path = None
Pre-Python 3.10, the only way to show this was:
doc_paths: Union[List[str], List[Path], str, Path] = None
Visually, I think the post-Python 3.10 syntax is a bit easier to reason about.
