Chapter 10: Object Oriented Programming

In Python, a class is ___________ for a concrete object.

• a blueprint
• a distraction
• an instance
• a nuisance

class Dog: def __init__(self, name, age): self.name = name self.age = age The correct way to instantiate the above Dog class is:

• Dog("Rufus", 3)
• Dog.create("Rufus", 3)
• Dog()
• Dog.__init__("Rufus", 3)

Object and class attributes are accessed using ___________ notation in Python.

• dash
• indent
• dot
• slash

In Python, a function within a class definition is called a:

• an operation
• a method
• a callable
• a factory
• a class function

What concept of OOP is demonstrated by the 'Dog' and 'Cat' classes in the above code?

• Encapsulation
• Inheritance
• Polymorphism
• Abstraction

What is Object-Oriented Programming (OOP)?

• A method of programming that uses procedures and functions.
• A programming paradigm based on the concept of "objects".
• A type of programming that focuses solely on data analysis.
• A programming technique used only in web development.

What does a class represent in OOP?

• A specific data type, like integers or strings.
• A blueprint for creating objects.
• A function inside an object.
• A variable used in object methods.

What are instance attributes in OOP?

• Attributes that are shared by all instances of a class.
• Functions that operate on the data of an object.
• Attributes specific to a particular instance of a class.
• The process of creating new objects.

How is a class attribute different from an instance attribute?

• Class attributes can only be accessed inside methods.
• Instance attributes are shared across all instances of the class.
• Class attributes have the same value for all class instances.
• There is no difference.

What is the purpose of the __init__ method in Python classes?

• To terminate an instance of a class.
• To initialize a newly created object.
• To inherit properties from a parent class.
• To delete an object's properties.
