Consider the following code:

class Bird:
    def __init__(self, species):
        self.species = species

class Parrot(Bird):
    def __init__(self, species, color):
        super().__init__(species)
        self.color = color

What is the primary purpose of using super().__init__(species) in the Parrot class constructor?

A:

To call the constructor of the Parrot class

B:

To create a new instance of the Bird class

C:

To initialize attributes of the Bird class in the Parrot class

D:

To access superclass attributes directly

Answer: C

super().__init__(species) is used to call the constructor of the superclass Bird and initialize the species attribute.

Consider the following code:

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

class EBook(Book):
    def __init__(self, title, author, format_type):
        super().__init__(title, author)
        self.format_type = format_type

What is the primary advantage of using super().__init__(title, author) in the EBook class constructor?

A:

To call the constructor of the EBook class

B:

To create a new instance of the Book class

C:

To initialize attributes of the Book class in the EBook class

D:

To access superclass attributes directly

Answer: C

super().__init__(title, author) is used to call the constructor of the superclass Book and initialize the title and author attributes.

Consider the following code:

class Shape:
    def __init__(self, color):
        self.color = color

class Square(Shape):
    def __init__(self, color, side_length):
        super().__init__(color)
        self.side_length = side_length

What is the primary advantage of using super().__init__(color) in the Square class constructor?

A:

To call the constructor of the Square class

B:

To create a new instance of the Shape class

C:

To initialize attributes of the Shape class in the Square class

D:

To access superclass attributes directly

Answer: C

super().__init__(color) is used to call the constructor of the superclass Shape and initialize the color attribute.
