Python - Polymorphism and Dynamic Behavior
How can you enforce that all subclasses of an abstract base class 'Processor' implement both 'process' and 'reset' methods, and also provide a concrete method 'status' that returns 'Ready'?

hard🚀 Application Q9 of Q15
Step-by-Step Solution
Solution:
Step 1: Mark 'process' and 'reset' as abstract methods
Use @abstractmethod decorator on these methods to require implementation in subclasses.Step 2: Define 'status' as a concrete method
Implement 'status' normally in Processor to provide shared functionality.Final Answer:
Use @abstractmethod on 'process' and 'reset' in Processor; define 'status' normally -> Option BQuick Check:
Abstract required methods + concrete shared method = Use @abstractmethod on 'process' and 'reset' in Processor; define 'status' normally [OK]
Quick Trick: Abstract methods require @abstractmethod; concrete methods are normal [OK]
Common Mistakes:
MISTAKES- Marking concrete methods as abstract
- Not using @abstractmethod for required methods
- Making abstract methods static incorrectly
