Show HN: LangTool – create semantic tools from Python functions and classes

LangTool adds a semantic layer on top of python functions and classes, to enable LLM interactions with functions and classes. LangTool borrows the concept of a Tool from LangChain (https://github.com/hwchase17/langchain). One of the goals of this project is to complement LangChain by providing a high-level interface for users to create tools on the fly.
