Known limitations

By default, nbQA will skip cells with invalid syntax. If you choose to process cells with invalid syntax via the --nbqa-dont-skip-bad-cells flag (see configuration), then the following will still not be processed:

• cells with multi-line magics;

• automagics (ideas for how to detect them statically are welcome!);

• cells with code which IPython would transform magics into (e.g. get_ipython().system('ls')).

Because nbQA converts the code cells in Jupyter notebooks to temporary Python files for linting, certain flags like flake8’s --per-file-ignores don’t work. The temporary Python files will not match the specified file patterns and ignored error codes will still surface (GH issue).

Any other limitation is likely unintentional - if you run into any, please do report an issue.
