Jupyter Language Server Protocol Server Extension

jupyter-lsp acts as a multi-language server WebSocket proxy for Jupyter Notebook and JupyterLab servers. It enables advanced IDE-like features such as code navigation, hover suggestions, linters, and autocompletion in Jupyter environments by leveraging the Language Server Protocol (LSP). It works in conjunction with a frontend extension, typically `jupyterlab-lsp`, and specific language servers (e.g., `python-lsp-server`). The library is actively maintained, with version 2.3.0 being the current stable release, supporting Python >=3.8.
