Python Programming - Inheritance

Exercise : Inheritance - General Questions
  • Inheritance - General Questions
1.
What is the purpose of the super() function in Python when working with inheritance?
To call the superclass constructor
To create a new instance of the subclass
To access class attributes directly
To override a method in the superclass
Answer: Option
Explanation:
The super() function is used to call the constructor of the superclass, allowing the subclass to initialize its own attributes while reusing the superclass's initialization code.
2.
What is method overriding?
Creating a new method in the subclass
Modifying the implementation of a method in the subclass
Calling a method of the superclass
Creating a new instance of the subclass
Answer: Option
Explanation:
Method overriding in Python involves redefining a method in the subclass with the same name and parameters as in the superclass, thereby providing a new implementation.
3.
How is multiple inheritance implemented?
By using the extends keyword
By using the inherit keyword
By using the super() function
By specifying multiple parent classes in the class definition
Answer: Option
Explanation:
Multiple inheritance in Python is implemented by specifying multiple parent classes in the class definition, separated by commas.
4.
What is the purpose of the isinstance() function?
To check if an object is an instance of a specific class
To create a new instance of a class
To access class attributes directly
To call a method of the superclass
Answer: Option
Explanation:
The isinstance() function is used to determine if an object is an instance of a specified class or a tuple of classes.
5.
In Python, what is the order in which classes are searched when resolving a method or attribute?
Bottom-up: From subclass to superclass
Top-down: From superclass to subclass
Random: No specific order
Alphabetical: Based on class names
Answer: Option
Explanation:
In Python, the method resolution order (MRO) follows a top-down approach, searching for methods or attributes first in the current class, then in its superclass, and so on.
