Python Institute PCPP1 Interview Questions

Practice real interview prompts based on Python Institute PCPP1 objectives. Review strong sample answers, listening cues, and common traps before the conversation gets real.

Question 1 of 8

The use of `ABCMeta` and `@abstractmethod` enforces a class's abstract nature, preventing instantiation until the abstract methods are implemented. This ensures that subclasses adhere to a specific interface, promoting code reuse and reducing the risk of unexpected behavior. This is a core principle of abstract classes in object-oriented design.
