Pyflakes

At Caktus, “clean” (in addition to “working”!) code is an important part of our delivery. For all new projects, we achieve that by using flake8. flake8 is a wrapper around several tools: pep8, pyflakes, and McCabe. pep8 checks to make sure your code matches the PEP 0008 style guidelines, pyflakes looks for a few additional things like unused imports or variables, and McCabe raises warnings about overly complex sections of code.
