unused-function-argument (ARG001)

Derived from the flake8-unused-arguments linter.

What it does

Checks for the presence of unused arguments in function definitions.

Why is this bad?

An argument that is defined but not used is likely a mistake, and should be removed to avoid confusion.

Example

def foo(bar, baz):
    return bar * 2

Use instead:

def foo(bar):
    return bar * 2
