Registering Virtual Subclasses

Medium Abstraction & Interfaces

Problem Statement

Create an ABC `Plugin`. Instead of standard inheritance, use `Plugin.register()` to register a separate, unconnected class `ThirdPartyPlugin` as a virtual subclass. Use `issubclass()` to verify the registration and print the boolean result.

Input Format

None

Output Format

Print True.

Constraints

None

Sample Output

True

Explanation

Virtual subclasses allow you to declare that a third-party or separate class implements an interface without modifying its original source code.

Starter Code

import abc

class Plugin(abc.ABC):
    pass

class ThirdPartyPlugin:
    pass

if __name__ == '__main__':
    # Register the subclass and verify with issubclass
    pass
