falsy-dict-get-fallback (RUF056)

Fix is always available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does

Checks for dict.get(key, falsy_value) calls in boolean test positions.

Why is this bad?

The default fallback None is already falsy.

Example

if dict.get(key, False):
    ...

Use instead:

if dict.get(key):
    ...

Fix safety

This rule's fix is marked as safe, unless the dict.get() call contains comments between arguments.
