What does the `id()` function return when called on an object?

The memory address of the variable label

A unique integer representing the object's identity

A boolean indicating if the object is mutable

A developer implements a deep copy of a custom class that contains a reference to a shared cache object. The cache is expensive to recreate and should be shared between the original and the copy. However, all other attributes must be independent. Which approach achieves this?

Use copy.copy() and manually deepcopy the other attributes.

Implement __deepcopy__ to deepcopy all attributes except the cache, which is assigned by reference.

Use copy.deepcopy() without any customization.

Use pickle to serialize and deserialize the object.

What does the `copy()` method on a list do?

Returns the same list object without creating a new one

Creates a completely independent copy of the list and all nested objects

Copies only the first element of the list

Creates a new list with the same top-level elements, but nested objects are shared

A developer writes a caching system where keys are objects. The system must distinguish between two objects that have equal values but different identities. Which approach correctly implements this distinction?

Use obj as the cache key directly.

Use obj == obj as the cache key.
