The strictest and most opinionated python linter ever!
This release fixes how ... is used. For example, it is common to define
function stubs / protocols like this:
def some_function(): ...
Now, ... will be excluded from several rules.
TooDeepNestingViolation not to trigger
on ... in functions and classesStatementHasNoEffectViolation not to trigger
on ... in functions and classes, when it is the only nodeThis minor version will be the last release with all the flake8 plugins.
In the future this project will be migrated to be used together with ruff.
python3.12 supportpython3.8 supportobject required base class exception:
since class Klass[_Type] must not contain object,
this rule is change to be the opposite:
object explicit base class must not be used.
You can use ruff to change all object-based types to the new style:
ruff check --select=UP004 --fix .
