Python - Polymorphism and Dynamic Behavior
What happens if you try to instantiate an abstract base class directly in Python?
What happens if you try to instantiate an abstract base class directly in Python?
easy🧠 Conceptual Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand abstract base class instantiation rules
Abstract base classes (ABCs) cannot be instantiated if they have abstract methods not implemented.Step 2: Check what happens when instantiating an ABC
Python raises a TypeError if you try to create an instance of an ABC with unimplemented abstract methods.Final Answer:
It raises a TypeError because abstract methods are not implemented -> Option DQuick Check:
Instantiating ABC = TypeError [OK]
Quick Trick: Cannot create ABC instance if abstract methods exist [OK]
Common Mistakes:
MISTAKES- Thinking ABCs can be instantiated like normal classes
- Confusing SyntaxError with TypeError
- Assuming abstract methods return None by default
