Jupyter Notebook
Iterative Python via live Jupyter kernel (hamelnb).
Gives you a **stateful Python REPL** via a live Jupyter kernel. Variables persist
across executions. Use this instead of `execute_code` when you need to build up
state incrementally, explore APIs, inspect DataFrames, or iterate on complex code.
Platforms: linux, macos, windows.
