What is Python Abstract Class?
A Python abstract class is a blueprint for other classes that cannot be instantiated directly. It serves as a template, defining methods that must be created within any subclass derived from it. Abstract classes are defined using the `abc` module, which provides the `ABC` class and the `@abstractmethod` decorator to designate abstract methods. These methods must be implemented by subclasses, ensuring a consistent interface across different implementations. Abstract classes are useful for enforcing certain behaviors in derived classes while allowing flexibility in how those behaviors are realized, promoting code reusability and organization in object-oriented programming.
