% ruff rule RUF059

unused-unpacked-variable (RUF059)

Derived from the Ruff-specific rules linter.

Fix is sometimes available.

What it does

Checks for the presence of unused variables in unpacked assignments.

Why is this bad?

A variable that is defined but never used can confuse readers.

If a variable is intentionally defined-but-not-used, it should be
prefixed with an underscore, or some other value that adheres to the
[lint.dummy-variable-rgx] pattern.

Example

def get_pair():
    return 1, 2


def foo():
    x, y = get_pair()
    return x

Use instead:

def foo():
    x, _ = get_pair()
    return x

This rule applies only to unpacked assignments. For regular assignments, see
unused-variable.

Options

• lint.dummy-variable-rgx
