flake8-unused-arguments

A flake8 plugin that checks for unused function arguments.

This package adds the following warnings:

• U100 - An unused argument.
• U101 - An unused argument starting with an underscore

Configuration options also exist:

• unused-arguments-ignore-abstract-functions - don't show warnings for abstract functions.
• unused-arguments-ignore-overload-functions - don't show warnings for overload functions.
• unused-arguments-ignore-override-functions - don't show warnings for overridden functions.
• unused-arguments-ignore-stub-functions - don't show warnings for empty functions.
• unused-arguments-ignore-variadic-names - don't show warnings for unused *args and **kwargs.
• unused-arguments-ignore-lambdas - don't show warnings for all lambdas.
• unused-arguments-ignore-nested-functions - don't show warnings for nested functions. Only show warnings for functions in the top level of a module, or methods of a class in the top level of a module.
• unused-arguments-ignore-dunder - don't show warnings for double-underscore methods. These methods implement or override native builtin methods which have a specific signature. Therefore arguments must always be present. This is the case of methods like __new__, __init__, __getitem__, __setitem__, __reduce_ex__, __enter__, __exit__, etc.
