What is Flake8 in Python?

Flake8 is a Python library that wraps PyFlakes, pycodestyle and Ned Batchelder’s McCabe script. It is a great toolkit for checking your code base against coding style (PEP8), programming errors (like “library imported but unused” and “Undefined name”) and to check cyclomatic complexity.

What is the difference between PEP8 and Pyflakes?

You can see the result of pep8 (error code is Exxx and Wxxx) and pyflakes (error code is Fxxx) are output together. This means the error of pyflakes (Fxxx) can be arranged in the configuration file by ignore and select like pep8. It’s easy to customize.
