Installing

Install the flake8 command line utility to run Python code through flake8 and find where it does not meet the standards:

pip install flake8

Configuring

Also covered in the documentation: http://flake8.pycqa.org/en/3.3.0/user/configuration.html

Relaxing Line Length Standard

To relax the max line length default, set it with the flake8 config file.

Put the following into your ~/.config/flake8 file:

[flake8]
max-line-length = 120

Ignoring certain errors and warnings

Suppose one of the warnings or errors is the bane of your existence and you never want to see it again. Easy enough, just add it to the ignore list in your flake config file at ~/.config/flake8:

[flake8]
ignore = E203, E266, E501, W503
