Abstract Base Class in Python
An abstract base class (ABC) in Python is a foundational class that defines a common API for a set of subclasses. It works as a template for other classes, ensuring that derived classes implement particular methods from the base class. ABCs are instrumental in enforcing a certain interface or behavior, which is useful in large systems with many class hierarchies.

Key Features of Abstract Base Classes
- Method Definitions: ABCs allow you to define methods that must be created within any child classes using the
@abstractmethoddecorator, thus enforcing an interface.
2. Prevent Instantiation: You cannot create instances of an abstract base class. Attempting to instantiate an ABC directly will result in an error.
3. Modularity: ABCs promote a more modular and cleaner design by allowing you to define a set…
