pep8-naming
Check PEP-8 naming conventions, plugin for flake8
Decision gist · record as of 2026-08-14
Yes. pep8-naming is a lightweight, zero-configuration flake8 extension that adds genuine value to code quality checks. It has no security vulnerabilities, permissive licensing, and low install friction. The aging maintenance status (466 days since release) is not a blocker—the plugin's scope is narrow and stable, and the underlying PEP 8 standard does not change frequently. Install it if you use flake8 and want to enforce naming conventions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires flake8 to be installed; the plugin only works as a flake8 extension, not as a standalone tool.
- Installs with minimal friction as a pure Python wheel depending only on flake8.
- The package is aging (466 days since last release) but remains in production/stable status with an active repository.

What it is and what it does
pep8-naming is a flake8 plugin that enforces PEP 8 naming conventions across your Python codebase. When installed alongside flake8, it automatically becomes available and checks for naming violations: class names should use CapWords, functions and variables should be lowercase, method arguments should follow specific patterns (cls for classmethods, self for instance methods), and imports should preserve the naming style of their source. It emits error codes N801 through N818 to identify specific violations.
The plugin integrates seamlessly into your existing flake8 workflow—once installed, it runs without additional configuration. It provides options to ignore specific names or patterns (useful for test frameworks that use setUp/tearDown conventions), and to recognize custom decorators as classmethods or staticmethods to avoid false positives. It supports Python 3.9+ and has been maintained since 2013.
Use it for
- Enforce consistent naming style across a team's codebase during CI/CD by adding pep8-naming checks to your flake8 configuration.
- Catch naming violations in pull requests automatically, flagging issues like improper function names or variable names that violate PEP 8.
- Configure custom decorator recognition to avoid false positives when using frameworks with non-standard method decorators.
- Validate codebases for naming convention compliance before refactoring or standardizing on PEP 8 style.
- Integrate into pre-commit hooks to catch naming issues before code is committed to the repository.
