Exercise : Inheritance - General Questions
  • Inheritance - General Questions
6.
How does Python support encapsulation in the context of inheritance?
By making all attributes public
By using private attributes and methods
By restricting inheritance
By removing the need for constructors
Answer: Option
Explanation:
Python supports encapsulation by allowing the use of private attributes and methods, denoted by a double underscore (e.g., __private_attribute), which are only accessible within the class.
7.
What is the purpose of the issubclass() function?
To check if an object is an instance of a specific class
To create a new instance of a class
To check if a class is a subclass of another class
To access class attributes directly
Answer: Option
Explanation:
The issubclass() function is used to check if a given class is a subclass of another class.
8.
What is the purpose of the __init__ method in Python classes?
To define class attributes
To create a new instance of the class
To initialize class attributes and perform setup operations
To access superclass attributes
Answer: Option
Explanation:
The __init__ method is a special method in Python classes used for initializing the attributes of an object and performing setup operations during object creation.
9.
What is the diamond problem in the context of multiple inheritance?
A naming conflict in class attributes
Difficulty in determining method resolution order
Ambiguity caused by a class inheriting from two classes with a common ancestor
Inability to use private attributes
Answer: Option
Explanation:
The diamond problem occurs in multiple inheritance when a class inherits from two classes that have a common ancestor, leading to ambiguity in method resolution order.
10.
In Python, what is the purpose of the super(type, obj) function?
To call the superclass constructor
To create a new instance of the subclass
To access class attributes directly
To explicitly specify the superclass
Answer: Option
Explanation:
The super(type, obj) function is used to call the constructor of the superclass, providing a way to initialize the superclass when working with multiple inheritance.
