x = 2
x = x * 3
x = x + 1
print(x)

a) 5
b) 7
c) 8
d) 9

Correct answer is d)
Explanation: The code multiplies the value of “x” by 3, adds 1 to it, and assigns the result back to “x”. Therefore, the value of “x” becomes 7, then 8.

22). What will be the value of the variable “y” after the execution of the following code?
x = [1, 2, 3]

Explanation: The round() function in Python rounds a number to the nearest whole number. In this case, num is 2.789, which is closer to 3 than to 2. Therefore, when you use round(num), it will round up to 3.0.

11). Python Variable must be declared before it is assigned a value:

a) True
b) False

Correct answer is b).
Explanation: No need to declare a variable before it is assigned a value

12). What are the things inside the list called?
a) variables
b) identifiers
c) elements

13). Identify the correct key value pair:
dict = {“Name”:”Rahul”, “Age”:24, “Occupation”:”Lawyer”}
a) Key is Rahul, Value is Name
b) Key is Name, Value is 24
c) Key is Name, Value is Rahul
d) Key is Name, Value is Age

Correct answer is c).
Explanation: Here, we are asked to identify the correct key value PAIR, so it will be option c).

14). Choose the correct option of the below code:

def num():
global a
a = 20
a = a+10
print(a)

a=10
num()
print(a)

a) 30
10

b) 30
30

c) 20
10

d) 20
20

Correct answer is b).
Explanation: Inside function num(), variable “a” is initially declared as global and assigned value as 20. Value of “a” will be printed when num() is called.
Variable inside the function will be given preference and hence the output of a will be a = a+10 = 20+10 = 30.
As we have declared “a” as global so when the function ends, outside print(a) will also output 30. So the correct answer is b).

15). What will be the output of the following code:
print(20//7)
a) 2
b) 2.0
c) 2.857142857142857

48. Problem to create an inheritance example in Python

In this Python oops program, we will create an inheritance example in Python. Python class called Dog that inherits from the Animal class.

Inheritance example in Python

Steps to solve the program

The Dog class extends the Animal class, which means it inherits the properties and methods of the Animal class.
The Dog class has its own constructor method __init__ that takes four parameters: name, color, breed, and weight. It calls the constructor of the Animal class using super() to initialize the name and color properties inherited from the Animal class. It also initializes two additional properties: self.breed to store the breed of the dog and self.weight to store the weight of the dog.
The Dog class overrides the print_details method inherited from the Animal class. It calls the print_details method of the Animal class using super().print_details() to print the name and color of the dog. Then, it prints the additional details: breed and weight.
The code creates an object dog of the Dog class by calling its constructor with the arguments “Jelly”, “Golden”, “Golden Retriever”, and 25.
The print_details method is called on the dog object to print the details of the dog, including the inherited name and color, as well as the breed and weight specific to the Dog class.
Thus, we have created an inheritance example in Python.

				
					class Animal:
    def __init__(self, name, color):
        self.name = name
        self.color = color
    
    def print_details(self):
        print("Name:", self.name)
        print("Color:", self.color)

class Dog(Animal):
    def __init__(self, name, color, breed, weight):
        super().__init__(name, color)
        self.breed = breed
        self.weight = weight
    
    def print_details(self):
        super().print_details()
        print("Breed:", self.breed)
        print("Weight:", self.weight)

# Create an object of the Dog class
dog = Dog("Jelly", "Golden", "Golden Retriever", 25)
dog.print_details()

Output:

				
					Name: Jelly
Color: Golden
Breed: Golden Retriever
Weight: 25

47. Problem to create an inheritance example in Python

In this Python oops program, we will create an inheritance example in Python. Python class called Animal with attributes name and color.

Inheritance example in Python

Steps to solve the program

The Animal class has a constructor method __init__ that takes two parameters: name and color. It initializes two instance variables: self.name to store the name of the animal and self.color to store the color of the animal.
The class also has a print_details method that prints the name and color of the animal.
The code creates an object animal of the Animal class by calling its constructor with the arguments “Lion” and “Golden”.
The print_details method is called on the animal object to print the details of the animal.
Thus, we have creates an inheritance example in Python.

				
					class Animal:
    def __init__(self, name, color):
        self.name = name
        self.color = color
    
    def print_details(self):
        print("Name:", self.name)
        print("Color:", self.color)

# Create an object of the Animal class
animal = Animal("Lion", "Golden")
animal.print_details()

Output:

				
					Name: Lion
Color: Golden

Create a Python class called ShoppingCart with attributes items and total_cost.

Create a Python class called Dog that inherits from the Animal class.

46. Problem to create a Python class example

In this Python oops program, we will create a Python class example. Python class called ShoppingCart with attributes items and total_cost.

Python class example

Steps to solve the program

The ShoppingCart class has a constructor method __init__ that initializes two instance variables: self.items as an empty list to store the items in the cart, and self.total_cost as 0 to track the total cost of the items.
The class also has three methods:
The add_item method takes item and cost as parameters and appends the item to the self.items list and adds the cost to the self.total_cost.
The remove_item method takes item and cost as parameters and removes the item from the self.items list if it exists and subtracts the cost from the self.total_cost.
The calculate_total_cost method returns the self.total_cost, representing the total cost of the items in the cart.
The code creates an object cart of the ShoppingCart class by calling its constructor without any arguments.
The add_item method is called three times on the cart object to add three items: “Shirt” with a cost of 250, “Pants” with a cost of 500, and “Shoes” with a cost of 1000.
The remove_item method is called on the cart object to remove the “Shirt” item with a cost of 250.
The calculate_total_cost method is called on the cart object to calculate the total cost of the items in the cart, and the result is assigned to the total_cost variable.
Finally, the contents of the cart are printed using cart.items, and the total cost is printed using total_cost.
Thus, we have created Python class example.

				
					class ShoppingCart:
    def __init__(self):
        self.items = []
        self.total_cost = 0
    
    def add_item(self, item, cost):
        self.items.append(item)
        self.total_cost += cost
    
    def remove_item(self, item, cost):
        if item in self.items:
            self.items.remove(item)
            self.total_cost -= cost
    
    def calculate_total_cost(self):
        return self.total_cost

# Create an object of the ShoppingCart class
cart = ShoppingCart()
cart.add_item("Shirt", 250)
cart.add_item("Pants", 500)
cart.add_item("Shoes", 1000)
cart.remove_item("Shirt", 250)
total_cost = cart.calculate_total_cost()
print("Items in cart:", cart.items)
print("Total Cost:", total_cost)

Output:

				
					Items in cart: ['Pants', 'Shoes']
Total Cost: 1500

Create a Python class called EBook that inherits from the Book class.

Create a Python class called Animal with attributes name and color.

45. Problem to create an inheritance example in Python

In this Python oops program, we will create an inheritance example in Python, Python class called EBook that inherits from the Book class.

Inheritance example in Python

Steps to solve the program

The Book class is defined with a constructor method __init__ that takes title, author, and pages as parameters and initializes the instance variables self.title, self.author, and self.pages with the provided values.
The class also has three methods: get_title, get_author, and get_pages.
The get_title method returns the title of the book.
The get_author method returns the author of the book.
The get_pages method returns the number of pages in the book.
The EBook class is defined as a subclass of the Book class. It inherits the attributes and methods of the Book class.
The __init__ method of the EBook class extends the functionality of the Book class’s __init__ method by adding two additional parameters: file_size and format. It initializes the instance variables self.file_size and self.format with the provided values.
The open_book method prints a message indicating the opening of the e-book.
The close_book method prints a message indicating the closing of the e-book.
The code creates an object ebook of the EBook class by calling its constructor and passing the title “Harry Potter”, author “J.K. Rowling”, number of pages 300, file size “10MB”, and format “PDF” as arguments.
The get_title, get_author, and get_pages methods inherited from the Book class are called on the ebook object to retrieve the respective book details, which are then printed.
The file_size and format attributes specific to the EBook class are accessed directly from the ebook object and printed.
The open_book method is called on the ebook object to simulate opening the e-book, and a corresponding message is printed.
The close_book method is called on the ebook object to simulate closing the e-book, and a corresponding message is printed.
Thus, we have created an inheritance example in Python.

				
					class Book:
    def __init__(self, title, author, pages):
        self.title = title
        self.author = author
        self.pages = pages
    
    def get_title(self):
        return self.title
    
    def get_author(self):
        return self.author
    
    def get_pages(self):
        return self.pages



class EBook(Book):
    def __init__(self, title, author, pages, file_size, format):
        super().__init__(title, author, pages)
        self.file_size = file_size
        self.format = format
    
    def open_book(self):
        print("Opening the e-book")
    
    def close_book(self):
        print("Closing the e-book")

# Create an object of the EBook class
ebook = EBook("Harry Potter", "J.K. Rowling", 300, "10MB", "PDF")
print("Title:", ebook.get_title())
print("Author:", ebook.get_author())
print("Pages:", ebook.get_pages())
print("File Size:", ebook.file_size)
print("Format:", ebook.format)
ebook.open_book()
ebook.close_book()

Output:

				
					Title: Harry Potter
Author: J.K. Rowling
Pages: 300
File Size: 10MB
Format: PDF
