What is the primary goal of Object-Oriented Programming (OOP)?
Code reusability and modularity
Efficient memory utilization
In Python, what is a class?
A blueprint for creating objects
What is an instance variable in a class?
A variable shared among all instances of a class
A variable defined outside the class
A variable specific to an instance of a class
A variable used for method overloading
What is encapsulation in OOP?
The process of converting a class into a module
Combining multiple classes into a single class
Restricting access to certain components of an object and hiding the implementation details
Creating a new instance of a class
What is the difference between a class variable and an instance variable?
Class variables are specific to instances, while instance variables are shared among all instances.
Class variables are defined outside the class, while instance variables are defined inside the class.
Class variables are shared among all instances, while instance variables are specific to each instance.
Class variables are used for method overloading, while instance variables are used for method overriding.
Inheritance in OOP allows a class to:
Combine multiple classes into one
Define multiple methods with the same name
Inherit properties and behaviors from a superclass
Restrict access to certain components of an object
What is polymorphism in OOP?
Combining multiple classes into one
Restricting access to certain components of an object
Defining multiple methods with the same name in a class
Providing a single interface for different types
Which keyword is used to achieve method overloading in Python?
Python does not support method overloading
What is the primary purpose of abstraction in OOP?
Combining multiple classes into one
Restricting access to certain components of an object
Defining multiple methods with the same name in a class
Simplifying complex systems by modeling classes based on their essential characteristics
What is the term for the process of creating a new class based on an existing class?
