Enhancements compared to dnanhkhoa/nbblack: Configurability: Try to read black config from pyproject.toml if available Override settings such as line length and black.TargetVersion if desired Uses black.formatcell to greatly simplify the.

Notebooks also support a few auxiliary magic commands: REPLs can share state only through external resources such as files in DBFS or objects in object storage. Variables defined in one language (and hence in the REPL for that language) are not available in the REPL of another language. When you invoke a language magic command, the command is dispatched to the REPL in the execution context for the notebook. This includes those that use %sql and %python. If your notebook contains more than one language, only SQL and Python cells are formatted.
