Project description
Run any standard Python code quality tool on a Jupyter Notebook
Table of contents
๐ Installation
In your virtual environment, run one of the following:
python -m pip install -U nbqa(minimal installation)python -m pip install -U nbqa[toolchain](install supported code quality tools as well)conda install -c conda-forge nbqa(if you use conda)
๐ Examples
Command-line
Reformat your notebooks with black:
$ nbqa black my_notebook.ipynb --nbqa-mutate
reformatted my_notebook.ipynb
All done! โจ ๐ฐ โจ
1 files reformatted.
Sort your imports with isort:
$ nbqa isort my_notebook.ipynb --nbqa-mutate
Fixing my_notebook.ipynb
Upgrade your syntax with pyupgrade:
$ nbqa pyupgrade my_notebook.ipynb --py36-plus --nbqa-mutate
Rewriting my_notebook.ipynb
See command-line examples for examples involving autoflake, check-ast, doctest, flake8, mypy, and pylint.
Pre-commit
Here's an example of how to set up some pre-commit hooks:
-
Put this in your
pyproject.tomlfile (see configuration for details)[tool.nbqa.mutate] isort = 1 black = 1 pyupgrade = 1 [tool.nbqa.addopts] pyupgrade = ["--py36-plus"]
-
Put this in your
.pre-commit-config.yamlfile (see usage as pre-commit hook)- repo: https://github.com/nbQA-dev/nbQA rev: 0.5.0 hooks: - id: nbqa-black additional_dependencies: [black==20.8b1] - id: nbqa-pyupgrade additional_dependencies: [pyupgrade==2.7.3] - id: nbqa-isort additional_dependencies: [isort==5.6.4]

๐ฌ 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
