useless-object-inheritance (UP004)

Derived from the pyupgrade linter.

Fix is always available.

What it does

Checks for classes that inherit from object.

Why is this bad?

Since Python 3, all classes inherit from object by default, so object can be omitted from the list of base classes.

Example

class Foo(object): ...

Use instead:

class Foo: ...
