What is the purpose of defining a class as abstract in Python?

To make all methods in the class static.

To prevent the class from being instantiated directly.

To allow the class to have multiple instances with the same state.

To make the class automatically inherit from all other classes.

What is required for a concrete subclass of an abstract class to be instantiable?

It must inherit from at least two abstract classes.

It must have a __init__ method.

It must be defined in the same module as the abstract class.

It must override all abstract methods with concrete implementations.

When a class inherits from multiple abstract classes, what must it do to be instantiable?

Implement only the abstract methods from the first parent class.

Call super().__init__() in its constructor.

Use the ABCMeta metaclass explicitly.

Implement all abstract methods from all parent abstract classes.

A developer has an abstract class `Shape` with an abstract method `area()`. They create a subclass `Rectangle` that implements `area()`. Later, they create another subclass `Square` that inherits from `Rectangle` and overrides `area()`. What is true about `Square`?

`Square` cannot override `area()` because it is abstract.

`Square` must implement `area()` again because it is a new class.

`Square` is abstract because it overrides an abstract method.

`Square` is concrete because `Rectangle` already implemented `area()`.

Part of the Advanced Object-Oriented Programming domain, which accounts for 35% of the PCPP-32-1 exam. Python Institute does not publish an official question count, but from its 65-minute exam (~25–45 total, ~9–16 in this domain), expect 1–1 from this objective — we provide 17 practice questions to prepare you well beyond it.
