dict-get-with-none-default (SIM910)

Derived from the flake8-simplify linter.

Fix is always available.

What it does

Checks for dict.get() calls that pass None as the default value.

None is the default value for dict.get(), so it is redundant to pass it explicitly.

ages = {"Tom": 23, "Maria": 23, "Dog": 11}
age = ages.get("Cat", None)

Use instead:

ages = {"Tom": 23, "Maria": 23, "Dog": 11}
age = ages.get("Cat")
