pre-requisites: of course, you must have some of the corresponding packages installed:
pip install black [--user]Then the extension provides
- a toolbar button
- a keyboard shortcut for reformatting the current code-cell (default: Ctrl-B)
- a keyboard shortcut for reformatting whole code-cells (default: Ctrl-Shift-B)
Syntax shall be correct. The extension will also point basic syntax errors.
If you use jupyter-contrib-nbextensions, proceed as usual.
