A simple extension for Jupyter Notebook and Jupyter Lab to beautify Python code automatically using Black.
Please note that since the Black package only supports Python 3.6+, so YAPF package will be used for the lower versions.
You can install this package using pip:
$ [sudo] pip install nb_black
Just put this code into the first cell in your Notebook, and that's all. :)
%load_ext nb_black
