Run any Python code quality tool on a Jupyter Notebook!
Project description
nbQA
Adapter to run any standard code-quality tool on a Jupyter notebook. Documentation is hosted here.
Installation
Install nbqa with pip:
pip install -U nbqa
Examples
Reformat your notebook with black:
$ nbqa black my_notebook.ipynb --line-length=96 --nbqa-mutate
reformatted my_notebook.ipynb
All done! ✨ 🍰 ✨
1 files reformatted.
Sort your imports with isort:
$ nbqa isort my_notebook.ipynb --treat-comment-as-code='# %%' --nbqa-mutate
Fixing my_notebook.ipynb
Check your type annotations with mypy:
$ nbqa mypy my_notebook.ipynb --ignore-missing-imports
my_notebook.ipynb:cell_10:5: error: Argument "num1" to "add" has incompatible type "str"; expected "int"
Run your docstring tests with doctest:
$ nbqa doctest my_notebook.ipynb
**********************************************************************
File "my_notebook.ipynb", cell_2:11, in my_notebook.add
Failed example:
add(2, 2)

**********************************************************************
1 items had failures:
1 of 2 in my_notebook.hello
***Test Failed*** 1 failures.
Configuration
Here's an example .nbqa.ini file - see
configuration
for more on configuration:
[isort]
config = setup.cfg
mutate = 1
addopts = --treat-comment-as-code '# %%%%'
[flake8]
config = setup.cfg
Usage as pre-commit hook
If you want to use nbqa with pre-commit,
here's an example of what you could add to your
.pre-commit-config.yaml file:
- repo: https://github.com/nbQA-dev/nbQA
rev: 0.1.30
hooks:
- id: nbqa
args: ["flake8"]
name: nbqa-flake8
alias: nbqa-flake8
additional_dependencies: ["flake8"]
- id: nbqa
args: ["isort", "--nbqa-mutate"]
name: nbqa-isort
alias: nbqa-isort
additional_dependencies: ["isort"]
Supported third party packages
In theory, nbqa can adapt any Python code-quality tool to a Jupyter Notebook.
In practice, here are the tools it's been tested with:
