Discuss it

Question 2

Which access modifier in Python allows an attribute to be accessed within the same package?

  • Public

  • Private

  • Protected

  • None of the above

Discuss it

Question 3

How does encapsulation contribute to data hiding in Python?

  • By making all attributes private

  • By providing access to attributes through getters and setters

  • By using name mangling to obscure attribute names

  • By restricting access to implementation details

Discuss it

Question 4

How can you enforce encapsulation in Python?

  • By declaring all attributes as private

  • By using access modifiers like public, protected, and private

  • By using only getter methods for attribute access

  • By avoiding the use of encapsulation in code

Discuss it

Question 5

Consider the following Python code:

class BankAccount:
   def __init__(self, balance):
       self.__balance = balance

   def withdraw(self, amount):
       if amount <= self.__balance:
           self.__balance -= amount
           return amount

           return "Insufficient funds"
 

  • Public

  • Private

  • Protected

  • Read-only

Question 7

What is the purpose of using getters and setters in Python?
