A developer is writing a tool that needs to list all class-level attributes (not methods) of a given class. The tool should only show attributes that are defined directly on the class, not inherited ones. Which approach correctly achieves this?

Iterate over `SomeClass.__dict__` and filter out callable objects.

Iterate over `SomeClass.__bases__` and collect their attributes.

Iterate over `dir(SomeClass)` and filter out callable objects.

Use `vars(SomeClass)` and include all values.

What does the __class__ attribute of an object return?

The base classes of the object's class.

The memory address of the object.

The name of the class as a string.

The class of which the object is an instance.

A developer is building a framework that must automatically convert all class variable names to uppercase. For example, a class variable `name` should become `NAME`. The conversion should happen at class definition time. Which approach should be used?

Use `__init_subclass__` to rename attributes in each subclass.

Use `type()` to create classes manually and rename attributes.

Use a class decorator that renames attributes after class creation.

Use a metaclass that iterates over the class namespace in `__new__`, renames keys to uppercase, and creates the class with the modified namespace.

A developer is working on a framework that needs to inspect the inheritance hierarchy of classes at runtime. The framework must determine the direct parent of a given class to understand its immediate lineage. Which attribute should be used?
