To apply these changes, remove the `--nbqa-diff` flag
See command-line examples for examples involving doctest, flake8, mypy, pylint, autopep8, pydocstyle, and yapf.
Pre-commit
Here's an example of how to set up some pre-commit hooks: put this in your .pre-commit-config.yaml file (see usage as pre-commit hook)
- repo: https://github.com/nbQA-dev/nbQA
rev: 1.2.0
hooks:
- id: nbqa-black
- id: nbqa-pyupgrade
args: [--py36-plus]
- id: nbqa-isort
If you need to select specific versions of any of these linters/formatters,
add them to additional_dependencies.

💬 Testimonials
Michael Kennedy & Brian Okken, hosts of the Python Bytes podcast:
This is really cool. I think it brings so much of the code formatting and code analysis, clean up to notebooks, which I think had been really lacking
Nikita Sobolev, CTO at wemake.services:
It is amazing!
Alex Andorra, Data Scientist, ArviZ & PyMC Dev, Host of 'Learning Bayesian Statistics' Podcast:
well done on
nbqa@MarcoGorelli ! Will be super useful in CI
Matthew Feickert, Postdoc at University of Illinois working on LHC physics:
nbqa in your pre-commit hooks along with @codewithanthony 's pre-commit CI service is amazing! Everyone using Jupyter notebooks should be doing this.
Girish Pasupathy, Software engineer and now core-contributor:
thanks a lot for your effort to create such a useful tool
Simon Brugman, Data scientist & pandas-profiling dev:
nbQA helps us to keep notebooks to the same standards as the rest of the code. If you're serious about your code standards, you should keep them consistent across both notebooks and python scripts. Great addition to the ecosystem, thanks!
Bradley Dice, PhD Candidate in Physics & Scientific Computing:
nbqa is a clean, easy to use, and effective tool for notebook code style. Formatting and readability makes a huge difference when rendering notebooks in a project's documentation!
James Lamb, engineer @saturn_cloud, LightGBM maintainer
today I learned about
nbqa, a command-line tool to run linters likeflake8over #Python code in @ProjectJupyter notebooks. Thanks to @jayyqi for pointing me to it. So far, I really really like it.
Lars Yencken, Tech Lead @ Our World In Data
Super useful! I only wish it was built-in to Jupyterlab.
Vincent D. Warmerdam, maintainer @ calmcode.io
Nice. nbQA looks like a great way to prevent the Untitled12.ipynb-phenomenon. I like!
