flake8-comments

Report redundant comments in python code.

An example of a bad comment:

# create user
user.create(force=True)

In this example, the comment gives even less information that the code itself. So, you can safely remove the comment without losing any information. The goal is to reduce the information redundancy, leaving in the code only what is actually important and helpful.

Installation

python3 -m pip install flake8-comments

Usage

Check that plugin was added in your flake8:

$ python3 -m flake8 --version
3.7.7 (flake8-comments: 0.1.0, mccabe: 0.6.1, pycodestyle: 2.5.0, pyflakes: 2.1.1) CPython 3.6.7 on Linux

If you don't see flake8-comments in the previous command output, check that flake8 and flake8-comments is installed in the same interpreter.

If everything is OK, run flake8:

python -m flake8 example.py

There are a few more good flake8 plugins targeted on cleaning up comments:

• flake8-eradicate detects commented out code.
• flake8-todos controls consistency of TODO comments.
• wemake-python-styleguide has a few checks targeted on comments, like if there are empty comments, too many noqa, no cover, bad shebangs.
