nb_black
A Jupyter Notebook/Lab extension that automatically formats Python code using Black (or YAPF for older Python).
What is nb_black?
nb_black is a Jupyter extension that automatically formats Python code in notebook cells using the Black formatter (or YAPF for Python <3.6). It solves the problem of inconsistent or messy code styling in interactive Jupyter environments by applying standardized formatting on execution.
Data scientists, researchers, and developers who use Jupyter Notebook or Jupyter Lab for Python programming and want to maintain clean, PEP 8-compliant code without manual formatting.
It integrates Black's opinionated, zero-config formatting directly into Jupyter workflows, saving time and ensuring consistency where manual formatting is often overlooked.
Overview
A simple extension for Jupyter Notebook and Jupyter Lab to beautify Python code automatically using black.
Use Cases
Best For
- Automatically formatting Python code in Jupyter notebooks to adhere to PEP 8
- Enforcing consistent code style across data science or research notebooks
