PyLint: Python static code analysis tool

An open-source tool for identifying programming errors, enforcing coding standards, and examining coding style in Python scripts.

What is PyLint?

PyLint is an open-source Python static code analysis tool that looks for programming errors, helps enforce coding standards, and examines coding style. Developed to be fully customizable, PyLint has support for plugins and can be integrated with IDEs like VS Code, PyCharm, and Atom to display warnings and errors directly during coding.

When run, PyLint generates a report detailing issues it found in code such as:

  • Unused imports and variables
  • Missing docstrings and type annotations
  • Too many branches, statements or local variables per function
  • Unused argument names in overridden methods
  • Unreachable code
  • Invalid name choice for variables, classes, functions etc
  • Duplicate keys/entries in dicts/sets

Beyond just flagging issues, PyLint can also enforce coding standards and style conventions if properly configured via pyproject.toml or pylintrc config files. It helps standardize project code over time.

With customizable output formats, exit codes and thresholds, PyLint can be integrated into CI/CD pipelines to fail builds when code quality thresholds are not met. This motivates developers to address issues before they make it to production.

Overall, PyLint is a powerful tool to analyze Python code, promote good coding practices and make code easier for humans to understand. Its flexibility and breadth of checks make it valuable for any Python project, especially larger codebases with multiple developers.
