Introduction to Linters

Linters are tools that analyze source code to flag programming errors, bugs, stylistic errors, and suspicious constructs. They help maintain code quality and ensure adherence to coding standards. Two popular linters are Pylint for Python projects, such as those using Django, and ESLint for JavaScript/TypeScript projects, such as those using Next.js.

Chapter 1: Pylint for Django Projects

What is Pylint?

Pylint is a widely used static code analysis tool for Python. It checks for errors in Python code, enforces a coding standard, looks for code smells, and offers simple refactoring suggestions.
