Linting and Static Analysis

Linters and static analyzers help detect style issues, bugs, and anti-patterns before runtime.

What They Do

  • Enforce style conventions (PEP8 for Python).
  • Detect possible errors (unused variables, unreachable code).
  • Suggest improvements (complexity, typing).
  • Python: flake8, pylint, mypy (static typing)
  • JavaScript: eslint

Run a simple check with flake8:

flake8 path/to/file.py

Interpreting Warnings

Not all warnings are errors — assess severity and fix relevant issues. Configure tool rules to match project preferences.
