In today's blog post, we dive into setting the minimum and maximum Python versions in pyproject.toml 🐍.
We explore how this impacts llamabot and discuss the new syntax for indicating the union of types in Python 3.10.
This new syntax is visually easier to understand, making our coding journey a bit smoother! 🚀👩💻👨💻
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.
h/t my colleague Jiayi Cox who helped me identify the bug in this issue.
