Pre-commit: A framework for managing and maintaining multi-language pre-commit hooks.įinally, let’s put it all together with pre-commit. It doesn’t like when binary operators are broken into multi-line statements.W503: line break before binary operator.In one of my libraries I am checking if an argument is a string, and in order to cover my bases with plain strings (str) and Unicode, I found that using basestring would work for all characters, including non-Latin characters.I do import some modules in order to get “Intellisense” when I peek into the details in P圜harm.In my case, this occurs again with the print statement where I am printing just one argument like this print arg.Since in Python 2 print is not a function, black adds a space between the print statement from Python 2, and the opening parenthesis.In my case, I am using 72 as the maximum allowed characters for my docstrings, in accordance with PEP 8, and ignoring the following errors: -ignore: Comma-separated list of errors and warnings to ignore (or skip).-max-doc-length: Maximum allowed doc line length for the entirety of this run.
PEP 8 recommends limiting docstrings or comments to 72 characters, which is exactly what I’m using for flake8. flake8: A python tool that glues together pep8, pyflakes, mccabe, and third-party plugins to check the style and quality of some python codeĪnthony Sottile ( has mentioned that he plans to drop support for Python 2.7 in future releases, maybe in version 3.9 or 4.0.įortunately, I can still use it for Python 2 by running the following command: black does not care about comments or docstrings, and isort cares even less, for obvious reasons enter flake8. If auto is specified, the version of the interpreter used to run isort (currently: 39) will be used.īut there’s still something missing. Default is to assume any Python 3 version could be the target, and use a union of all stdlib modules across versions. -python-version: Tells isort to set the known standard library based on the specified Python version.Profiles include: black, django, pycharm, google, open_stack, plone, attrs, hug. -profile: Base profile type to use for configuration.-multi-line: Multiline output (0-grid, 1-vertical, 2-hanging, 3-vert-hanging, 4-vert-grid, 5-vert-grid-grouped, 6-vert-grid-grouped-no-comma, 7-noqa, 8-vertical-hanging-indent-bracket, 9-vertical-prefix-from-module-import, 10-hanging-indent-with-parentheses).The options used are mainly to be compatible with black (see here): $ isort -multi-line 3 -profile black -python-version 27.
