Configuration settings are applied in three ways: user, project, and the
--config CLI argument. The user (global) configuration is read first. Next
the project configuration is loaded, and overrides any settings found in both
the user (global) and project configurations. Finally, if the
argument is used on the command line, the specified file is loaded and
overrides any settings that overlap with the user (global) and project
The user settings are read from the
~/.config/flake8 file (or the
~/.flake8 file on Windows).
[flake8] ignore = E226,E302,E41 max-line-length = 160 exclude = tests/* max-complexity = 10
At the project level, the
files are read if present. Only the first file is considered. If this file
does not have a
[flake8] section, no project specific configuration is
Per Code Line¶
To ignore one line of code add

ignore option is not in the configuration and not in the arguments,
only the error codes
E241/E242 are ignored
(see the warning and error codes).
This is a (likely incomplete) list of settings that can be used in your config
file. In general, any settings that
pycodestyle supports we also support and
we add the ability to set
max-complexity as well.
