Abstraction in Python MCQs Exercise I

Ques 1 Abstraction

What is abstraction in Python?

A Hiding implementation details
B Exposing implementation details
C Creating complex data structures
D Ignoring error handling

Ques 2 Abstraction

What is the purpose of an abstract method in Python?

A It's used for private functionality.
B It's automatically inherited from the base class.
C It's optional to implement in the derived class.
D It must be implemented in the derived class.

Ques 3 Abstraction

In Python, what is the purpose of providing default implementations in an abstract class?

A To prevent derived classes from overriding methods.
B To make the class non-abstract.
C To provide a starting point for derived classes.
D To increase the speed of method execution.

Ques 4 Abstraction

What is the output of the following python Code? 

from abc import ABC, abstractmethod
class Shape(ABC):
    @abstractmethod
    def area(self):
        pass
class Circle(Shape):
    def __init__(self, radius):
        self.radius = radius
    def area(self):
        return 3.14 * self.radius * self.radius
circle = Circle(5)
print(circle.area())

A 31.4
B 78.5
C 15.7
D Error: Cannot instantiate abstract class
