PEP-8 Naming Conventions

Check the PEP-8 naming conventions.

This module provides a plugin for flake8, the Python code checker.

(It replaces the plugin flint-naming for the flint checker.)


You can install, upgrade, uninstall pep8-naming with these commands:

$ pip install pep8-naming
$ pip install --upgrade pep8-naming
$ pip uninstall pep8-naming

Plugin for Flake8

When both flake8 and pep8-naming are installed, the plugin is available in flake8:

$ flake8 --version
2.0 (pep8: 1.4.3, pyflakes: 0.6.1, naming: 0.2)

By default the plugin is enabled.

These error codes are emitted:

N802 function name should be lowercase
N803 argument name should be lowercase
N804 first argument of a classmethod should be named 'cls'
