What is the role of indexes in a database and why are they used?

Static code analysis tools (e.g., pylint, flake8, mypy for Python) analyze source code without executing it to find errors, potential bugs, and style violations.

How to use:

• Integration into the development process: run checks when saving a file or before committing.
• CI/CD: include static analysis in the pipeline to automatically check code on each push.
• Rule configuration: adapt the configuration to the project standards, disable or enable necessary checks.

For example, pylint will point out unused variables, syntax errors, PEP8 violations, and mypy will check types if type annotations are used.

This helps to detect errors early, improve code quality, and maintain a consistent style within the team.
