A lint-like tool for Python to identify common errors quickly without executing code

pyflakes

passive checker of Python 2 and 3 programs

Pyflakes is program to analyze Python programs and detect various errors. It works by parsing the source file, not importing it, so it is safe to use on modules with side effects. It's also much faster. Unlike PyLint, Pyflakes checks only for logical errors in programs; it does not perform any checks on style. This is the Python 2 command line `pyflakes3` program.
