Pylint is a static code analysis tool for Python or Jupyter Notebooks. It checks your Python code for errors, enforces a coding standard, and looks for code smells. CodeRabbit runs Pylint version 4.0.7.

​
Supported Files

Pylint will run on files with the following extensions:
  • *.py
  • .ipynb (using nbQA)

​
Configuration

Pylint is enabled by default. Enable or disable it with .coderabbit.yaml or the CodeRabbit web UI:
.coderabbit.yaml
Pylint supports the following config files:
  • .pylintrc
  • pylintrc
  • .pylintrc.toml
  • pylintrc.toml
CodeRabbit will not run Pylint if no config file is found.

​
What CodeRabbit runs

Pylint runs per-file in a sandbox. We validate the config before execution.

​
Security policy and restrictions

CodeRabbit skips Pylint if the configuration declares init-hook, load-plugins, or load_plugins. These options can load repository-controlled code before analysis. When any of these options is present, CodeRabbit skips the Pylint run and produces no Pylint findings for the repository.

​
When we skip Pylint

CodeRabbit will skip running Pylint when:
  • No config file is found.
  • The config contains init-hook.
  • The config contains load-plugins.
  • The config contains load_plugins.
  • Pylint is already running in GitHub Actions, GitLab CI, CircleCI, or Azure Pipelines.
When the configuration contains any of these three code-loading options, CodeRabbit skips the Pylint run and produces no Pylint findings for the repository.

​
Profile behavior

In Chill mode, Pylint filters out:
  • Warnings and conventions
  • E0401 (Unable to import)
  • C0301 (Line too long)
In Assertive mode, all findings are reported.

​
Features

Pylint can detect many issues such as:
  • Coding standard violations (PEP8)
  • Unused variables and imports
  • Undefined variables
  • Code smells and refactoring suggestions
  • Error-prone constructs
  • And many more
